NP-1000/NPP-1000
The NP-1000 and NPP-1000 are advanced design neutron monitoring safety channels already in use at many research reactor installations worldwide. All NP-1000 channels feature current mode analog circuitry for percent power and pulse power monitoring (NPP-1000 only) using signals generated by an ionization chamber. They include a built-in pulse integrator circuit (NPP only) and connect to computer analysis systems and/or hard-wired scram systems. The integrity of NP-1000 output signals is assured by the use of isolation devices.
