Gentlemen:

Subject: NRC Region I Inspection Report No. 50-293/90-20
This refers to the routine safety inspection conducted by Messrs. J. Macdonald, A. Cerne,
I
W. Olsen, and D. Kern of this office August 16 October 8,1990 at the Pilgrim Nuclear
Power Station, Plymouth, Massachusetts. Areas examined during this inspection are
described in the NRC Region ! Inspection Report which is enclosed with this letter.
l
The September 2 manual reactor scram and plant shutdown was extensively reviewed by the
i
resident staff in this report as well as by the Special Inspection Team dispatched to the site in
response to the event (Inspection Report 50-293/90-21). Region I management concluded
.
that the licensed operators on shift at the time of the event displayed strong performance in
'
response to the component failures and system malfunctions encountered while bringing the
i
plant to cold shutdown conditions. Additionally, the multi disciplinary analysis team
j
(MDAT) provided effective and comprehensive investigation of each event anomaly and
i
t
recommended appropriate specific and programmatic corrective actions.
'
Notwithstanding effective event response, we remain concerned with the number of
challenges presented to the operators during the event and the apparent contribution of the
maintenance program to these challenges. We are aware of your self assessments of the
'
maintenance program as well as the enhancements planned and implemented in response to
weaknesses you identified. We will assess the effectiveness of these changes and the
,
,
maintenance program in general during the NRC Maintenance Team Inspection to be
'
l
conducted November 516,1990.
Additionally, it appears that one of your activities involving the temporary leak repair of a
shutdown cooling system suction valve was not conducted in accor/.ance with NRC
!
requirements. You are required to respond to this letter following the instructions in the
enclosed Notice of Violation. In your response you should adoress 'he adequacy of the
temporary leak seal program in general and specifically describe administrative measures in
,
place to ensure that quality standards are maintained during program application.
