     SUBJECT:
                     NRC INSPECTION REPORT NO. 50155/97009(DRP)
     Dear Mr. Powers:
     On August 4,1997, the NRC completed an inspection at your Big Rock Point Nuclear Plant. The
     enclosed report presents the results of that inspection.
     During the 6 week period covered by this inspection, operations, maintenance, and engineering
     activities were generally performed satisfactorily. However, the NRC was concerned about two
     issues identified during this inspection period. The first issue involved lack of a questioning
     attitude during the repairs to the equipment lock door, resulting in a hydraulic leak and the
     potential to breach containment. The second issue was inadequate engineering support noted
     during the work activities to repair the number two spent fuel pool heat exchanger tubes.
     Engineers improperty translated eddy current data, resulting in a failure to plug two degraded
     heat exchanger tubes. Also, engineering personnel could not provide justification for the
     plugging criterion provided prior to the start of work activities, resulting in the need to reanalyze
     and establish new tube plugging criteria. Attention to detail and questioning attitudes by plant -
     staff and management at Big Rock Point will be key factors in ensuring that the upcoming
     dismantlement of plant systems will be performed in a manner that complies with regulatory
     requirements and will maintain public health and safety.
     Good work control processes were noted during the spent fuel bundle reconstitution. Also, good
     radiological performance was noted in support of both a fuel bundle reconstitution and the SFP
     heat exchanger repairs.
     No violations were cited based on the results of this inspection.
                                               Sincerely,
                                               /s/Geoffrey E. Grant
                                              Geoffrey E. Grant, Director                                \
