-m EM D Wms Vee Pmset March 28, 1986 Trojan Nuclear Plant Docket 50-344 License NPF-1 Director of Nuclear Reactor Regulation ATTU:

Mr. Steven A. Varga Director, PWR-A Project Directorate No. 3 U.S. Nuclear Regulatory Commission Washington DC 20555

Dear Sir:

Safety Parameter Display System on July 9, 1985, the Trojan Safety Parameter Display System (SPDS) was placed into operation. A few outstanding items / issues remained and were addressed in our July 3,1985 letter. On August 6-8, 1985, an NRC team visited Trojan to observe the SPDS and assess the status of the SPDS implementation. On March 3, 1986, the NRC team released their report which identified potential concerns in the areas of system reliability, system testing, operator training and operator acceptance of the system.

As reported in our July 3, 1985 letter, the reliability of the SPDS over the two previous years had been very poor.

This fact was also recognized by the NRC audit team. The system has, however, performed very reliably since that time. The system has been online since July 1985 with only minor outages for scheduled maintenance.

System testing is near completion. The Site Acceptance Test has been completed satisfactorily with only one minor open item. The point-by-point input verification is approximately 70 percent complete and the remainder will be completed during the upcoming refueling outage.

Initial operator training was completed prior to declaring the system operable in July 1985. At the time of the NRC audit, the operators were in the process of becoming familiar with a new system.

Since that time, the SPDS has been utilized by the operators and they are continuing to become more comfortable with the system.

In fact, the SPDS was used with great effectiveness during the 1985 Radiological Emergency Response Plan exercise in November, after the tean visit.

A user's manual is currently being prepared to aid the operators and assist in their training.

This~ training will improve the operator's familiarity with the capability of the SPDS during accident conditions.

In conclusion, we believe the Trojan SPDS is a reliable and useful aid to Operations personnel. We are continuing to work to improve the system and the operators knowledge of its capabilities, and we are evaluating ways to better integrate the system with other emergency response capabilities.

The audit report sununarizing perceptions that existed 8 months ago does not reflect the current status of the system.

Sincerely.
