Trojan Nuclear Plant Docket 50-344 License NPF-1 Mr. John B. Martin Regional Administrator, Region V 1450 Maria Lane, Suite 210 Creekside Oaks Office Park U.S. Nuclear Regulatory Commission Walnut Creek CA 94596-5368
Dear Mr. Martin:
TROJAN NUCLEAR PLANT Corrective Action Systems A number of events including restrained thermal expansion of the Reactor Coolant System Piping and the misapplication of throttle valves in the Containment Spray system indicate a need to improve the approach to determine the root cause of equipment performance problems at Trojan.
Accordingly, more management emphasis and additional personnel resources will be devoted to programs for corrective actions, with particular attention to improving our capability to determine the root cause of problems.
Specific actions to be taken are as follows:
1.
The corrective action systems currently in use will be integrated into a new Nuclear Division Procedure (NDP 600-0), to assure uniform application by Plant and headquarters personnel.
2.
The Event Report procedure currently in use at Trojan will be expanded into a Nuclear Division Procedure (NDP 600-3) for use by both Plant and headquarters personnel to report problems.
It will be broadened to prescribe the process to be followed for trouble shooting and conduct-ing root cause evaluations.
3.
The Nuclear Division Procedure (NDP 600-1) for nonconforming equipment will be revised to better define " rework" and " repair", and to require that root cause evaluations be performed for significant deficiencies identified during the conduct of maintenance.

Special training will be conducted using techniques such as MORT, to assure that personnel who are involved in root cause evaluations are well-versed in techniques for such evaluations.
5.
A team of technical personnel reporting to the Quality Assurance Manager will be assigned to independently review evaluations of events having nuclear safety implications until we are satisfied that adequate and complete root causes are being determined by the line management organization.
6.
A quality hot line will be established as part of a program to demon-strate management commitment to "doing it right" and to stress the responsibility of everyone to report their concerns to appropriate management or through the hot line.
Work on these changes will commence immediately and be fully implemented by September 30, 1986. The quality hot line will be placed in operation prior to July 15, 1986.
On a related matter, the completion schedule for the system walkdowns/
checkouts / reviews by Plant system engineers, as committed to in our letter to you dated May 22, 1986, will be reassessed to determine if this work can be completed before the end of 1987. Reliance on contractors for this work will be minimized.
An outside firm will be engaged to conduct an independent review of our programs, processes, organization, resources, and management to assess the technical adequacy of design modifications and related technical support for Trojan and identify areas where improvements are needed.
My intent throughout these changes is to prevent the occurrence of avoidable equipment degradation, challenges, or failures by throughly evaluating problems when they occur.
Sincerely,,
Bart D. Withers Vice President Nuclear I
