August 2006 d. Plant Operator Familiarization With Facility Operation and Trial Use of Operating and Emergency Operating Procedures Plant modifications, setpoint adjustments, and parameter value changes, in conjunction with the increased decay heat generation associated with higher power operation, can impact the execution of abnormal plant procedures and EOPs. For example, the EPU may change the timing and sequence of significant operator actions that are relied upon in abnormal plant procedures and EOPs, or it could impact the accident mitigation strategies that are credited in abnormal or emergency operating procedures. For each EPU LAR, the technical branch responsible for operator licensing and human performance should review the impact of the requested power uprate on operator training and human factors in accordance with separate SRP guidance. These reviews should include an evaluation of the changes in operator actions, procedures, and training (including necessary changes to the control room simulator) resulting from the EPU. The initial test program objectives, as described in RG 1.68, Revision 2, included plant staff familiarization with facility operation and trial use of abnormal plant procedures and EOPs. However, based on previous review experience, it is not expected that power ascension testing will normally be performed solely for procedure verification or operator familiarization. Nonetheless, the possibility exists that the review of operator training (including simulator training) and human factors aspects of the EPU could indicate a need to perform power ascension testing for procedure verification or operator familiarization. e. Minimal Reductions in the Margin of Safety The licensee’s justification for omitting a test (or tests) from the test program may consider the extent of the EPU’s impact on the results of the safety analyses and may consider such factors as the amount of remaining margin to SRP acceptance criteria, the sensitivity
