Dear Mr. Cockfield:
\\
Subject: HRC Inspection of Trojan Nuclear Plant
l
l
On hay 18-21, 1987, Messrs. E. T. Baker, A. J. H. Lee, and Ms. C. M. Abbate of
I
the Office of Nuclear Reactor Regulation and a consultant conducted a special
inspection of activities authorized t>y NRC License No. NPF-1. The findings were
l
discussed with you and with members of your staff at the end of the inspection.
!
This letter forwards the hRC inspection report.
Areas examined during this inspection included aspects of your 10 CFR 50 Appendix J, and American Society of Mechanical Engineers (ASME) Boiler and
Pressure Vessel Code,Section XI test programs applicable to check valves,
check valve maintenance, and location of check valves with respect to sources
of turbulence, and your response to the Institute for Nuclear Power Operation
(INPO) Significant Operating Event Report (SOER) 86-03.
No violations of
the NRC requirements were identified. Two items were identified, concerning
check valve testing which will be considered during the review of your inservice
i
testing program for the second ten year interval. The inspection did reveal
that to date valves located in areas of turbulent flow (e.g., pump discharge
check valves) were not all receiving preventive maintenance or being tested
1
in a manner that would ensure valve disk and seat integrity.
However, the
newly established check valve reliability and enhanced testing programs, if
effectively implemented, should result in improvements in check valve
performance and plant safety.
In accordance with 10 CFR 2.790(a) a copy of this letter and the enclosure
will be placed in the NRC Public Document Room.
Should you have any questions
concerning this inspection, please contact E. Baker (301) 492-4783 or T. Chan
(301) 492-8997.
Sincerely
e700130379 h h44
