4.4 GAMMA AND NEUTRON FAULTS
Criterion Condition Decrement
Faults GH, GL, or NH present? 5 seconds of availability / fault
When a background line is written to the daily file, a boundary check is performed that can produce
Gamma High, Gamma Low, and Neutron High faults. If a gamma or neutron background measurement is
out of range, the associated fault line is written to the daily file instead of the regular Gamma Background
or Neutron Background line. The purpose of the faults is to notify the operator of unusual background
data
