SUBSEQUENT CORRESPONDENCE WITH THE LICENSEE CLOSED THIS ITEM WITHOUT FURTHER ACTION REQUIRED BY BRAIDWOOD.  NO VIOLATION RESULTED.

No Color. The guidelines established by Branch Technical Position (BTP) Chemical Engineering Branch (CMEB) 9.5-1, Section C.5.c, Alternative or Dedicated Shutdown Capability, paragraph (2)(d), required that the process monitoring function should be capable of providing direct readings of the process variables necessary to perform and control the shutdown functions. Analyzed instrumentation for the reactor coolant pump (RCP) seal leak-off temperature indication was not available to the operators outside of the main control room. This temperature indication was necessary for the operators to determine when to trip the RCPs prior to reaching RCP seal temperature limitations. The license’s failure to provide an analysis that demonstrated the capability of plant operators involved in post-fire shutdown activities to have access to the seal leak-off temperature process variable, necessary to perform and control the reactor coolant makeup function, is a violation of the Braidwood Station’s Facility Operating License (Section 1R05.5b.(2)).
