Finding

Title

Licensee-Identified Violation

Description

TS 3.3.1 requires reactor protection instrumentation of each function identified in TS Table3.3.1-1, to be operable. Contrary to this requirement, Entergy personnel identified that as found readings had, on two occasions, exceeded operability criteria for the overpower delta temperature trip and rod stop functions for a loop 4 reactor coolant temperature bistable module. Specifically, this exceedance was identified following surveillance testing on September 17, 2009, and during subsequent reviews, was also identified to have occurred during the previous surveillance testing conducted on June 26, 2009. Entergy technicians subsequently replaced the bistable module, and documented this issue in the corrective action program for resolution under condition report CR-IP3-2009-03817. In addition, Entergy personnel determined a contributor to this operability issue was caused by test inputs (voltages) that were not recorded in certain physical locations of the circuit to validate their use in the circuit and therefore, allow validation of accurate trip set points. The inspectors determined that this finding was of very low safety significance. The bistable affected only one of four redundant channels and the trip of two channels is required to generate a trip signal. Two redundant channels remained operable to generate the trip signal and satisfy the safety function throughout the period when this bistable was inoperable.
