SUBJECT:
NRC INTEGRATED INSPECTION REPORT 50-334/97-01 AND 50-412/97-01
l
Dear Mr. Cross:
'
The NRC conducted an inspection of the Beaver Valley Power Station (BVPS) facilities from
.
February 9 to March 15,1997. The enclosed report presents the results of that
>
inspection.
2
During the 5-week period covered by this inspection period, your operations personnel
,
performed well when challenged by equipment failure or unexpected occurrences during
planned evolutions. Examples ncluded prompt Unit 2 operator response to a failed
l
secondary process rack power supply and to an unexpected reactor coolant system (RCS)
boration during a degas evolution. Further, a Unit 1 shift supervisor identified an
inadequate containmant hydrogen recombiner surveillance test in sufficient time to
preclude a reactor shutdown. Your Quality Services Unit has been proactive and provided
valuable independent oversight for station activities. Recent engineering audit and
technical specification surveillance testing audit findings were noteworthy.
Notwithstanding, our inspectors noted several examples of poor performance. Insufficient
planning and system knowledge during troubleshooting on a Unit 2 secondary process rack
unexpectedly caused two atmospheric steam dump valves to open. An unrepresentative
chemistry sample resulted in an unanticipated boration of the RCS. Post maintenance
testing was performed on service water system valves without proper authorization. Each
of these activities unnecessarily challenged plant operation. Further, weaknesses in
surveillance test scheduling and failure to account for instrument accuracies placed the
units in shutdown action statements on two occasions. Your continued attention to these
i
issues is warranted.
