Gentlemen:
Subject: NRC Combined Inspection No. 50-272/90-12; 50-311/90-12
This letter transmits the findings of a special inspection conducted by Messrs.
T. P. Johnson, G. M. Tracy, S. T. Barr, and S. M. Pindale during the period
April 11 - 18, 1990, at the Salem Nuclear Generating Station.
The findings of
the special inspection were discussed with Mr. L. K. Miller of your staff at
the conclusion of the inspection.
The.inspection was conducted to review the circumstances surrounding the mis-
calculation of the safety injection pumps' flow rates in the emergency core
cooling system (ECCS) flow balance verification surveillance procedure.
The
miscalculation resulted in each unit being operated with the flow rates for one
of the two intermediate-head safety injectior pumps exceeding the maximum value
allowed by Technical Specifications.
Although the miscalculation was identified by your staff and reported to the
NRC, we note that a similar miscalculation, involving surveillances for the
high-head charging pumps, was identified by your staff in January 4, 1990.
The
January 4, 1990, event and your corrective actions were also reported to the
NRC (Reference LER No.90-002).
Your corrective actions for the previous event
indicated all similar surveillances were reviewed and no additional examples
were identified.
The identification of a second example of apparent failure to meet Technical
Specification ECCS surveillance requirements raises concerns about the adequacy
of your corrective actions for the previous event.
Consequently, we plan to
conduct an Enforcement Conference with you at the NRC Region I office in the
near future to discuss this matter .
