SUBJECT:
SYSTEMATIC ASSESSMENT OF LICENSEE PERFORMANCE (SALP)
REPORT NO. 50-293/93-99
Dear Dr. Boulette:
This letter forwards the Pilgrim Nuclear Power Station SALP report for the
period March 14, 1993, to October 8, 1994. This SALP was' conducted under the
revised process that was implemented by the Nuclear Regulatory Commission
(NRC) on July 19, 1993. The revised SALP process rates licensee performance
in four functional areas: Operations, Maintenance, Engineering and Plant
Support. The Plant Support functional area includes:
radiological controls,
security, emergency preparedness, fire protection, chemistry and housekeeping.
Overall, the NRC observed strong safety performance at your facility during
this assessment period. The use of multi-disciplined analysis teams was very
successful in resolving complex technical issues. Your staff conservatively
shut down the reactor on several occasions to perform maintenance when
critical components, such as the scram solenoid pilot valve diaphragms,
exhibited accelerated degradation. Your organization's self-assessment, root-
cause analysis and quality assurance work was generally excellent. The
ovcrsight and independent assessment provided by both the Nuclear Safety
Review and Audit Committee and the Operations Review Committee contributed to
safe plant operation.
Despite generally strong performance, some areas require continued management
attention to improve the safety performance of the Pilgrim Station. There
were instances in the beginning of the SALP period where senior plant
management failed to provide a vigorous safety focus.
For example, senior
management failed to recognize the importance of a significant decrease of
water level in the east bay of the intake structure during a December 1993
storm. The potential effect of the level decrease on the operation of the
salt service water pumps was not fully evaluated until highlighted by the NRC.
In another case, while performing a leak repair on an ASME Code Class 1
boundary valve, senior management did not assure that pre-job planning
included an evaluation of the failure consequences for various repair options
and development of thorough failure mitigation strategies. Maintenance
supervisory oversight is an additional area where continued management
attention is warranted.
Late in the SALP period, poor supervisory oversight
and craft performance problems were observed during maintenance performed on
both the emergency and station blackout diesel generators. We are aware that
you hgve formed a task force to review the maintenance performance issues.

Operations was again rated Category 1 and exhibited strong performance during
the latter half of the assessment period, recovering from a performance
dccline in the early part of the assessment period. Operations response to
plant transients and off-normal conditions was generally excellent. Thorough
shift turnovers, formal communications between operators, and a highly
'
effective operator training program contributed to safe plant operations.
Maintenance was again rated as Category 2.
Management oversight and control
of activities were generally strong and communications with other departments
were excellent. Your programs for inservice inspection, inservice testing,
check valve testing and snubber testing were generally strong.
Preventive
maintenance was generally effective; however, a weaknesses was noted in the
management controls used for the preventive maintenance deferral process.
Recent inadequacies in supervisory oversight were evidenced by problems
resulting from maintenance activities on the emergency diesel generators and
the station blackout diesel generator. A relatively high number of component
failures that challenged operators and continuing procedural problems
detracted from otherwise very good performance in this area.
Performance in Engineering has improved and is rated as Category 1.
Strong
management support and oversight were exemplified by the successful
implementation of several major plant modifications, including the service
water piping replacement, the fatigue study of reactor primary system
components and the switchyard improvement program. The use of multi-
disciplined analysis teams has been successful in resolving several complex
.
plant problems including degraded scram time test results, reactor core
isolation cooling turbine lubricating oil problems, and recirculation pump
1
trips.
Plant Support was rated as Category 1.
Overall, the plant support functions
contributed very effectively to support safe plant operations.
Performance in
the radiological controls area continued to be good with some areas for
improvement, including the "as low as is reasonably achievable" (ALARA)
program.
Excellent performance was noted in the radiological effluent and
environmental monitoring programs. There was continued excellent performance
in the emergency preparedness program; however, two exercise weaknesses were
noted during the full participation exercise. The security program
performance continued to be outstanding.
Fire-protection program
implementation and housekeeping were generally effective.
We have scheduled a management meeting for November 30, 1994, at the Pilgrim
Nuclear Power Station site, open to the public, to present our assessment. At
'
the meeting, you and your staff should be prepared to discuss our assessment
and any initiatives you plan to take to address the concerns noted in our
evaluation.
