Fusion energy is having a moment – an increasingly fruitful one – but as radio astronomers and particle physicists know, bigger and better experiments and simulations mean data deluges that quickly become difficult to manage. In a paper for the 22nd Smoky Mountains Computational Sciences and Engineering Conference – hosted virtually last year – researchers from General Atomics, Oak Ridge National Laboratory and the University of Virginia outlined their vision for a science gateway to help manage and share fusion data that the authors expect to “substantially balloon in the near future.”

Taking A New Angle to Boost Plasma Performance in Advanced Tokamaks

Magnetic confinement is one of the leading paths to fusion energy. One variant of this approach uses a device known as a tokamak like the DIII-D National Fusion Facility to confine the super-hot plasmas inside powerful magnetic fields until fusion occurs. The tokamak approach has demonstrated exceptional ability to contain these plasmas, which are created when the fuel gas is heated until atoms separate into charged particles and serve as the fuel for nuclear fusion.

The U.S. National Science Foundation and the Czech Science Foundation are funding a new collaborative project of scientists from the University of California San Diego and General Atomics in the U.S. and the Institute of Physics of the Czech Academy of Sciences which aims to leverage the capabilities of the ELI Beamlines multi-petawatt laser facility. Researchers hope these experiments can achieve a breakthrough by demonstrating efficient generation of dense gamma-ray beams.

At a quiet commercial park in Poway, California, in the dry hills above San Diego, there are few clues that the future is being built inside the warehouse-like machine workshop. But this is where the Central Solenoid, a five-storey, 1,000-tonne superconducting electromagnet at the heart of ITER is being manufactured by General Atomics, a defence and energy contractor better known for making Predator drones.

For a collaboration that is often measured in microns, it is a bit ironic that the Laboratory for Laser Energetics (LLE) and General Atomics (GA) are more than 2500 miles apart.

In a tokamak, impurities can move through the edge of the plasma and enter the plasma’s core, contaminating it and reducing power. However, researchers do not fully understand impurity transport along the plasma edge. Researchers at the DIII-D National Fusion Facility, in partnership with the University of Tennessee, deployed a diagnostic called a collector probe to measure tungsten content in the edge of plasmas. 

The first of seven modules that make up a crucial component of an international effort aimed at turning the vast potential of nuclear fusion energy into a reality has been successfully shipped overseas from the San Diego area — and another is about to head out the door this week. General Atomics is fabricating and testing pieces of what will make up the Central Solenoid — the world’s most powerful magnet — that will be inserted into the mammoth ITER nuclear fusion project, under construction near the town of Cadarache in southern France.

Imagine almost limitless clean, carbon-free electricity. That’s the dream that’s driving scientists to build the world’s biggest magnet.

The world's most powerful magnet, the "Central Solenoid," is finally here. At 59 feet tall, 14 feet wide, and 1,000 tons, the decade-in-the-making magnet is truly massive. Appropriately, it will soon find a home at the world's largest fusion reactor. General Atomics completed construction of the magnet's first module earlier this year. 

Darren & Jack Talk With Guest General Atomics Director of Engineering and Projects John Smith About Building The Worlds Biggest Magnet.

World's strongest magnet developed in San Diego, being sent to Europe

John Smith, director of engineering and projects at General Atomics, joins ABC 10News to discuss the development of the world's strongest magnet and its eventual usage.

This week marked two major milestones for fusion energy. On June 15, San Diego-based General Atomics (GA) said it was ready to ship the first module of the Central Solenoid—the world’s most powerful magnet—which will become a central component of ITER, the world’s largest experimental fusion facility that is under construction in France.

The strongest magnet in the world, capable of lifting an aircraft carrier, is set to head to France, where it will be used as part of a nuclear fusion generator. The 59-foot tall, 1,000-ton Central Solenoid magnet will form a crucial part of the fusion generator because it will use its intense magnetic field to control a band of superheated plasma at temperatures of tens of millions of degrees.

It may turn out to be one of the most consequential road trips of all time. This week, key components for one of the world’s most powerful magnets, so strong it can lift an aircraft carrier 2 metres off the ground, were strapped onto a 24-axle truck in California.

One of the world’s most powerful magnets is the Central Solenoid of the megaproject ITER. It will be as tall as a six-story building, can lift an aircraft carrier, and is designed to play a central role in an upcoming experiment that might just provide humanity with the means to produce limitless energy without harming the planet.

The world’s most powerful magnet is being shipped to France for installation in the core of ITER, the experimental fusion reactor. It is hoped that ITER will prove the feasibility of creating fusion energy on an industrial scale by replicating the process seen in the centre of our sun.

Engineers in the U.S. are preparing to ship the first part of the world's most powerful magnet to France, where it will help power a state-of-the-art nuclear fusion reactor.

The world's largest magnet, a decade in the making, is ready to be shipped to France where it will form the centrepiece of a project to replicate the power of the sun. This will form a central part of ITER, a £17 billion ($23.95 billion) machine that creates fusion energy on Earth, built in France by 35 partner countries to find a 'true renewable power'.

General Atomics is about to ship the first piece of a crucial component of an ambitious and expensive international nuclear fusion project under construction in France. In segments, the San Diego-based company is building the world’s most powerful magnet — called the Central Solenoid — that will be inserted into the ITER project, which seeks to harness the power of nuclear fusion and deliver on the long-anticipated prospect of generating a virtually inexhaustible supply of carbon-free energy to the globe.

Ben Penaflor is computer systems manager at General Atomics, which operates the DIII-D National Fusion Facility in San Diego, California, for the US Department of Energy. This post is part of a series on how the COVID-19 pandemic is affecting the personal and professional lives of physicists around the world.

Scientists at the DIII-D National Fusion Facility have released a new design for a compact fusion reactor that can generate electricity and help define the technology necessary for commercial fusion power. General Atomics, which operates the DIII-D facility in San Diego, California, for the U.S. Department of Energy, says the approach is based on the “Advanced Tokamak” concept pioneered by the DIII-D program.

If fusion is to contribute to decarbonizing electricity generation by mid century, the US must begin to construct a grid-scale pilot fusion-power plant well before a self-sustaining fusion reaction is first achieved, says a new report from the National Academies of Science, Engineering, and Medicine (NASEM).

After nearly five years of fabrication and testing, one of the first pieces of an incredibly powerful magnet built by General Atomics has been completed and will be shipped to Europe in the coming months, to be inserted into the heart of an ambitious international nuclear fusion project.

After enduring a battery of rigorous tests, the first of seven superconducting magnet modules that will make up the beating heart of the ITER international fusion reactor has earned a clean bill of health.

One of the great challenges in fusion tokamaks is how to keep the core of a plasma hot enough that fusion can occur while maintaining a temperature at the edge of the plasma low enough that it doesn’t melt the tokamak’s walls. This requires dissipating the heat and particles flowing towards the wall without reducing the performance of the core. Researchers developed a new way to address the core-edge integration challenge by combining a new divertor geometry recently installed at the DIII-D National Fusion Facility at General Atomics with impurity radiation.

The main criticism about nuclear fusion has been that its vast potential as a commercial source of energy has always been just out of reach. But a group of the nation’s top fusion scientists and researchers just issued a report to the Department of Energy that calls for the U.S. to build a fusion pilot plant by the 2040s. The 80-page report, written by the Fusion Energy Sciences Advisory Committee, was two years in the making.

San Diego-based General Atomics has already taken on a major role in the United States’ contribution to an international, multi-billion-dollar nuclear fusion experiment under construction in France. On Friday, the company announced it will do a little bit more. General Atomics won a contract to develop assemblies that will transmit microwave heating into the centerpiece of the project, called ITER.

Scientists at the DIII-D National Fusion Facility, operated by General Atomics, have solved a key challenge to maintaining density in the core of a fusion reactor without direct core fueling.

As the operator of the DIII-D National Fusion Facility for the U.S. Department of Energy Office of Science, General Atomics has been a pioneer in fusion energy research for decades. As part of the Oak Ridge National Lab Hub, General Atomics is advancing computational chemistry techniques on IBM Q Network hardware in an effort to improve the understanding of plasma-facing materials within the extreme environment of fusion energy tokamaks.

Picture an airplane that can only climb to one or two altitudes after taking off. That limitation would be similar to the plight facing scientists who seek to avoid instabilities that restrict the path to clean, safe and abundant fusion energy (link is external) in doughnut-shaped tokamak (link is external) facilities. Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and General Atomics (GA) have now published a breakthrough explanation of this tokamak restriction and how it may be overcome.

Using the power of the National Ignition Facility (NIF) the world’s highest-energy laser system, and targets manufactured by General Atomics, researchers at Lawrence Livermore National Laboratory (LLNL) and an international team of collaborators have developed an experimental capability for measuring the basic properties of matter, such as the equation of state (EOS), at the highest pressures thus far achieved in a controlled laboratory experiment. The results are relevant to the conditions at the cores of giant planets, the interiors of brown dwarfs (failed stars), the carbon envelopes of white dwarf stars and many applied science programs at LLNL.

The DIII-D National Fusion Facility, operated by General Atomics for the U.S. Department of Energy (DOE), is the largest magnetic fusion research facility in the U.S. The mission of the DIII-D research program is to establish the scientific basis for the optimization of the tokamak approach to fusion energy production. The DIII-D program is a cornerstone element in the U.S.’s fusion program strategy. DIII-D research has delivered multiple innovations and scientific discoveries that have transformed the prospects for fusion energy.

Scientists at the DIII-D National Fusion Facility have for the first time studied the internal structure and stability of high-energy runaway electron (RE) beams in a tokamak. The scientists used hard X-ray radiation to study the RE beams. The finding could provide a way to control the damaging potential of RE beams. This could contribute to future power production using tokamak fusion power plants.

Practical, economic generation from fusion is not yet here, and it’s a solid bet that it will not arrive on the grid before the 2030s. Yet that reality is considerably closer than many people realize.

Nuclear fusion’s energy potential is vast. Scientists believe it could, theoretically, lead to the construction of commercial power plants that would deliver virtually unlimited amounts of energy without leaving a trail of waste behind. But efforts to harness the technology have been exceedingly slow.However, a small step forward has been made by scientists at the DIII-D National Fusion Facility operated by San Diego-based General Atomics.

Research into fusion energy has long been a driver of innovation in magnet technology. General Atomics (GA) has been developing HTS magnets based on REBCO conductor to advance the magnetic fusion energy development program in conjunction with operating the DIII-D National Fusion Facility in San Diego for the U.S. Department of Energy.

Researchers at DIII-D, a Department of Energy user facility operated by General Atomics in San Diego, are working on ways to improve electron-cyclotron current drive (ECCD), which uses powerful microwaves to heat electrons in the plasma in a tokamak device. ECCD is important because it helps stabilize the plasma as the tokamak heats the plasma to temperatures necessary for fusion reactions.

Lawrence Livermore National Laboratory scientists have employed compound parabolic targets manufactured by San Diego’s General Atomics to achieve relativistic effects associated with significantly greater laser intensities. This innovation has substantially expanded the experimental capabilities of the National Ignition Facility’s Advanced Radiographic Capability (ARC) laser.

A team of scientists—including Christopher Holland of theUniversity of California San Diego, Jeff Candy of General Atomics, and Nathan Howard of MIT—are using the world’s smartest and fastest supercomputer, the 200-petaflop IBM AC922 Summit system at the Oak Ridge Leadership Computing Facility (OLCF), to better understand turbulence, an important characteristic of plasma behavior that affects performance in fusion devices such as ITER.https://www.hpcwire.com/off-the-wire/resear...

Alex Nagy, an engineer who for four decades has been working on ways to heat and fuel plasmas in experiments aimed at harnessing the process that powers the sun and stars, was named a Distinguished Engineering Fellow by the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) on Dec. 20.

San Diego-based General Atomics is working to find an abundant source of energy without pollution or nuclear waste. The goal of this nuclear fusion program known as DIII-D is to harness a virtually inexhaustible source of energy that, theoretically, could supply electricity for power plants all over the world while emitting no carbon pollution or long-lived nuclear waste. And to help with that effort, the Department of Energy has given researchers a 5-year funding extension.

Recently, researchers at the DIII-D National Fusion Facility operated by General Atomics in San Diego discovered a new way to eliminate magnetic islands in fusion plasmas, which are unstable structures within the magnetic fields that tear holes in the field and release energy from the plasma, stopping the fusion reaction. For future fusion power plants to produce electricity efficiently, the growth of magnetic islands must be prevented or eliminated.

Researchers at the DIII-D National Fusion Facility operated by General Atomics in San Diego have demonstrated a new approach for injecting microwaves into a fusion plasma that doubles the efficiency of a critical technique that could have major implications for future fusion reactors. The results show that launching the microwaves into the plasma via a novel geometry delivers substantial improvements in the plasma current drive.

A team at the DIII-D National Fusion Facility operated by General Atomics in San Diego recently took a different approach to studying fast ions, which can damage fusion tokamaks. The research showed promising results that have not only yielded insights into the physics of the particles themselves, but they may also lead to new and reliable ways to monitor and manage how well fast ions are contained in future reactors.

Energy Group Director of Business Development Zabrina Johal appeared on an episode of the Titans of Nuclear podcast to discuss her background as a nuclear engineering officer in the U.S. Navy and why nuclear fission and fusion are critical elements of the energy mix – and what we need to do make it happen.

Today, the U.S. Department of Energy (DOE) announced $14 million in funding for 10 university-led research projects using the DIII-D National Fusion Facility, operated by General Atomics in San Diego.  A major goal of the research is to develop methods of sustaining steady-state or continuous operation of fusion reactors, an essential step toward eventually making nuclear fusion a practical energy source.

San Diego is known for many things – its climate, its beaches, its naval base. But there is a little-known industry in the region that seeks to change the future of humanity. All the stars in the universe rely on fusion, and San Diego has its own star in DIII-D at General Atomics: a donut-shaped chamber that heats matter to more than 100 million degrees.

The energy potential for nuclear fusion has always been remarkably ambitious but progress has usually been painfully slow. But researchers and collaborators working on the DIII-D National Fusion Facility based at San Diego’s General Atomics have completed a series of successful experiments with an approach called “Super-H Mode” that has improved performance so dramatically they think it will accelerate the development of nuclear fusion reactors that could result, in theory, in ...

A plasma disruption can damage tokamak walls and other structures. Mitigating disruptions means injecting impurities into the plasma. The impurities radiate the plasma energy evenly around the tokamak as light.

A team at the DIII-D National Fusion Facility, operated by General Atomics, recently achieved high-pressure operation of a plasma configuration known as a reverse D. They did so while maintaining a low pressure, stable region near the plasma edge that was inherently free of reactor-damaging disruptions. Their work turned conventional wisdom about plasmas on its head.

After shutting down for 11 months for upgrades, an ambitious U.S. Department of Energy nuclear fusion program is about to resume conducting experiments at San Diego?s General Atomics. The DIII-D National Fusion Program looks to further developments in the decades-long quest to harness the vast potential of nuclear fusion for practical purposes, such as generating electricity at power plants.

The new technologies installed during the 11-month upgrade will play a key role in developing the scientific basis for fusion as a reliable and nearly limitless energy source. When experiments restart in early June, researchers will converge on San Diego to use these tools to optimize the performance of fusion plasmas and help bring practical fusion energy closer to realization.

To eight-year-old David Hill, the UFO-like top and spindly legs of the Space Needle looked like the future. Outside his suburban Seattle home, he'd climb trees to watch workers as they built the Space Needle in preparation for the 1962 World's Fair. When he saw the Needle finally completed, he felt like he was experiencing "tomorrow" right in the present day.

The next round of Discovery Science Program experiments at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) will further explore plasma astrophysics, hydrodynamics, nuclear physics, equation of state, material science, and particle acceleration.

Workin...

General Atomics Director of Business Development for the Energy Group Zabrina Johal talks about how her service as a nuclear-trained officer in the U.S. Navy prepared her for a career in the nuclear industry and helping GA innovate in advanced nuclear.

Researchers at the DIII-D National Fusion Facility have demonstrated a revolutionary new technique to achieve "inside-out" cooling of fusion plasmas before a disruption occurs. The new approach transforms prospects for fusion energy by potentially solving three major problems—efficiently radiating away the plasma's heat, reducing forces by the plasma on the fusion device, and preventing the formation of energetic electron beams.

An international team at the DIII-D National Fusion Facility has developed a new way to suppress damaging waves in fusion plasmas using microwaves. The researchers believe the results can lead to the development of approaches to control or reduce the presence of waves in the magnetic fields and could help chart a path to more efficient fusion energy.

As the hubbub of interest and activity surrounds development of small modular reactors (SMRs) hovering between 60 MW and 300 MW, and medium-sized nuclear reactors of under 700 MW, several nuclear technology vendors including General Atomics have quietly been developing micro-reactors—which are of 10 MW or less.

Dr. Christina Back, General Atomics’ vice president for Nuclear Technologies and Materials, testified Sept. 13 before the Senate Committee on Environment and Public Works about the benefits of advanced nuclear technology, specifically accident tolerant fuel (ATF) for commercial nuclear reactors.

Before scientists can capture and recreate the fusion process that powers the sun and stars to produce virtually limitless energy on Earth, they must first learn to control the hot plasma gas that fuels fusion reactions. In a set of recent experiments at the DIII-D National Fusion Facility, operated by General Atomics for the DOE, scientists have tamed a plasma instability in a way that could lead to the efficient and steady state operation of ITER, the international experiment under constructio...

Naysayers are nothing new for General Atomics. While others say nuclear power is on the decline, the privately held company is betting on a vision of small reactors cooled by helium gas. It’s a long-term vision since GA’s reactor design is not ready for commercial use.

Four researchers from San Diego-based General Atomics have received awards totaling $6.9 million from the U.S. Department of Energy to continue their work on harnessing the vast potential of nuclear fusion as a source of energy. In addition, DOE granted $7.8 million to eight researchers across the country to come to General Atomics to perform research at the DIII-D National Fusion Facility that houses what is called a “tokamak” — a doughnut-shaped fusion reactor that is crucial...

Postdoctoral associate Cristina Rea at MIT’s Plasma Science and Fusion Center (PSFC) is exploring ways to predict disruptions in the turbulent plasma that fuels fusion tokamaks. Tokamaks use magnetic fields to contain hot plasma in a donut-shaped vacuum chamber long enough for fusion to occur. Chaotic and unpredictable, the plasma resists confinement, and disrupts.

Researchers in the Oak Ridge National Laboratory (ORNL) Stable Isotope Group are accustomed to helping scientists identify solutions that optimize the design of their experiments and enable the novel use of isotopes. This division works closely with California-based General Atomics on a national fusion energy tokamak device called DIII-D, located in San Diego, and is collaborating with them on improving methods for tracing the erosion, transport, and re-deposition of tungsten (W) at the plasma m...

The U.S. is pouring funding into developing new fuel technology for advanced nuclear reactors in a bid to help the flagging industry. On April 27, it awarded General Atomics (GA) $3.2 million for two projects that the San Diego, California-based company is developing, including an accident tolerant fuel (ATF) solution that the company says is “truly revolutionary.”

A variety of ATF designs have been proposed by DOE-funded groups and other manufacturers. Both new fuel-rod cladding materials and new fuel types are under development, including an advanced silicon carbide (SiC) composite fuel-rod cladding being developed by General Atomics. This effort has the support of multiple stakeholders across the nuclear industry, from fuel suppliers and DOE national laboratories to the Electric Power Research Institute, utilities, and plant owners.

General Atomics has received two awards from the U.S. Department of Energy totaling more than $3.26 million to continue the San Diego-based company's work on developing new types of fuel for advanced nuclear reactors. The awards will go to two projects aimed at speeding the development and licensing of a reactor fuel that features silicon carbide composite fuel cladding that contains uranium carbide fuel pellets.

The development of fusion energy has led to many important spinoff technologies that are being used around the world, including the GA-developed Electromagnetic Aircraft Launch System (EMALS), which leveraged expertise from the DIII-D National Fusion Facility. The U.S. Navy is using EMALS on the USS Gerald R.

Funding for research in nuclear fusion was fully restored by Congress in the omnibus spending bill, reversing what supporters feared might be declining interest in the research. An executive of General Atomics said during his March 6 testimony in Congress that he sensed a new attitude toward fusion science.

Theresa Wilks has come full circle, at least geographically. After receiving an MS and PhD from Georgia Tech, she returned to her home state of California in 2016 as an MIT postdoctoral associate doing fusion energy research at the DIII-D tokamak. Her research is part of a growing collaboration MIT has with DIII-D, a national user facility in San Diego operated by General Atomics.

After months of doubt, the federal government has agreed to boost 2018 funding for the U.S. share of the world’s largest and most ambitious nuclear fusion project. That means what may be the endeavor’s most important piece — a massive magnet being assembled by San Diego-based General Atomics — will continue this year without interruption.

Fast-gated imaging diagnostics are a key element of high-energy-density (HED) experiments in stockpile stewardship. GA scientists were part of a team that developed a new type of high-speed x-ray imager. This breakthrough sensor is capable of recording multiple frames with nanosecond separation and represents a 50-fold improvement in shutter speed over previous devices.

Recent technological advancements could turn environmentalists into huge fans of nuclear power, according to a nuclear physicist. Physicist Christina Back said her company General Atomics has developed nuclear fuel that can keep advanced nuclear power plants from melting down, which could largely address public fears about expanding the U.S. nuclear fleet.

As a physicist who has vested my career in energy research, the claim that nuclear energy will never be cost-effective is one I have heard countless times but refuse to believe. The importance of safe and efficient power generation to energy security — and national security — challenges me to push the boundaries of what is possible. Nuclear energy is by far the largest source of clean, non-intermittent electricity in the United States.

Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory and General Atomics have simulated a mysterious self-organized flow of the superhot plasma that fuels fusion reactions.

Global demand for electricity will increase by 70% over the next 30 years, requiring a variety of cheap and clean technologies to meet that demand. Nuclear energy must be a significant portion of that energy mix, but it can't be unless we overcome the challenges nuclear electricity faces today: high electricity cost, safety concerns, waste issues, and proliferation fears. http://community.energycentral.com/community/energybiz/better-tomorrow-brought-you-affordable-safe-nuclear-energy

The US Domestic Agency and vendor General Atomics completed a major milestone on 6 April by winding the first module for the ITER central solenoid. The feat was accomplished at the General Atomics Magnet Development Facility in Poway, California.

Organized by the Department of Commerce and the Organization of American States, the delegation consisted of more than 50 government and business leaders from Latin America and Asia who traveled to the U.S. to learn about innovation and entrepreneurship. They started their weeklong tour in Arizona and finished in San Diego.

Big time fun with physics: General Atomics educational outreach program volunteers drew big crowds at the annual Science and Engineering Festival EXPO at Petco Park this weekend, with kid-friendly demonstrations for a crowd of more than 30,000 of the important work our Magnetic Fusion Energy program does in developing fusion as a new clean-energy source and deepening our understanding of the universe. http://timesofsandiego.com/tech/2016/03/05/exploding-cucumbers-robot-cobras-welcome-to-petco-st...

The Inertial Fusion Technology Division of General Atomics is contributing to a breakthrough in fusion research by enabling the path of energy in fast ignition laser fusion targets to be "seen". The researchers published their findings online in the Jan. 11 issue of the journal Nature Physics.

KUSI TV highlights the Energy Group?s innovative technology to deliver an isotope that was facing critical shortage, in a landmark U.S.-Canada partnership http://www.kusi.com/story/30153902/nordion-welcomes-milestone-funding-from-national-nuclear-security-administration-to-advance-new-source-of-medical-isotopes

The Department of Energy?s National Nuclear Security Administration has approved a cooperative agreement that enables development of a medical isotope used in approximately 80 percent of nuclear diagnostic imaging procedures in the United States, equating to about 50,000 medical procedures every day, and millions more per year. worldwide.  http://www.murr.missouri.edu/press_releases.php

Igniting and sustaining the fusion of light nuclei requires an astonishingly high temperature, on the scale of 100 million kelvin. No material can tolerate such an environment, and for some 60 years scientists have been studying plasmas bound within a cage of magnets to insulate the walls of a reaction vessel from the intense heat inside it. Equally important, the confinement helps avoid cooling the bulk plasma to the point of quenching the reaction. (PDF)

It is generally acknowledged that the future of nuclear power, with all of its low carbon virtues, will rely on the emergence of small reactors that greatly reduce costs and increase deployment opportunities. Reactors that manufacturers can produce in assembly-line fashion and transport to their destination on trucks will allow utilities and other users to purchase capacity in affordable chunks, rather than requiring them to spend the roughly $10 billion that today's large reactors require.

General Atomics is working on a new paradigm that would drive down the cost of nuclear power by 30 percent, and solve some of the safety issues that plague nuclear power today. http://www.kpbs.org/news/2012/may/21/better-nuclear-power-plant

Years before the safety of nuclear reactors was jeopardized by the devastating hydrogen explosion at Fukushima, U.S. scientists successfully developed revolutionary technology that promises to create safe, clean and virtually unlimited electrical power. http://www.utsandiego.com/news/2012/mar/11/tp-technology-can-solve-americas-energy-crisis/?page=1

Today, due partly to the high capital cost of large power reactors generating electricity via the steam cycle and partly to the need to service small electricity grids under about 4 GWe,b there is a move to develop smaller units. http://www.world-nuclear.org/info/inf33.html
