Neutron detector cable monitoring
Creators
Description
In a neutron detector connected by a cable with a current amplifier for the signal based on (n,e)-processes, any change in the insulation resistance of the cable is monitored by means of an a-c voltage which is super-imposed on the offset voltage of the amplifier. The resistance-dependent a-c variable at the output of the amplifier, is used to make a limit indicator respond via a connected filter. The invention is of importance particularly for monitoring the internal core instrumentation of pressurized-water reactors
