.

! Dear Mr. Cockfield:

\

Subject: HRC Inspection of Trojan Nuclear Plant  ;

l 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 l

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
