Only the neutron portion of the FCT is required

There are a limited number of faults that can affect both pillars; troubleshoot each pillar independently starting with the control pillar. Failure of components that are common to both gamma detector channels should affect both channels similarly. If the problems in the channels are different (GH in one and GL in the other), troubleshoot the gamma channels separately.

If there are no or low neutron counts on a channel, place a source on the affected detector before performing troubleshooting steps
