!!r. Darrell G. Eisenhut, Director Division of Licensing Office of Nuclear Reactor Regulation U. S. Nuclear Regulatory Commission Washington, DC 20555

Dear Mr. Eisenhut:

Your letter of October 1,1980 requested us to provide pertinent informa-tion relative to environmental qualification tests to be conducted within the next 2 years on equipment used or to be used in our facility. Please be informed that at the present time, PCE is participating in two joint efforts to qualify equipment for use in several facilities. These are the Utility Transmitter Qualification Group program for Rosemont and Foxboro pressure transmitters, and the Technology for Energy Corporation Acoustic Valve Flow Monitors Qualification Test program.

The Urility Transmitter Qualificatior Group program is being coordinated by Wisconsin Electric Power Company. The details of this program have already been reported to you by their letter of October 31, 1980. Pres-ently, the only pressure transmitters installed at the Trojan Nuclear Plane being qualified by this test program for a harsh environment are the Foxboro N-E10 series. These transmitters are used for pressurizer level measurement.

We plan to install either N-E10s or Rosemont 1153Ds for auxiliary feedwater flow indication, steam flow indication, turbine first-stage pressure, and Containment pressure indication within the next few years.

The safety valve flow-monitoring system testing is being conducted by Technology for Energy Corporation in Knoxville, Tennessee. This test program is attempting to qualify their Model 1414 monitoring system for use in indicating pressurizer safety valve position. Three of these units were installed at Trojan last year in response to NUREG-0578. This test. program began in August 1980 and is expected to be. completed before d)\\

the beginning of 1981.

t Although we are not directly controlling the conduct of either of these test. programs, we are tracking the progress and reviewing the test plans 560 8 01A0gh.mcynm

Mr. Darrell G. Eisenhut November 25, 1980 Page two and any changes to them in order to ensure that the programs will produce a usable qualification document for Portland General Electric Company.

Our cognizant contact in both of these cases is:

Gary Johnson Portland General Electric Company 121 S. W. Salmon Street Portland, OR 97204 Telephone number (503)226-8069.

As part of the environmental qualification review required by IE Bulletin 79-OlB, we have identified several items for which testing may prove to be a desirable means for resolving environm2atal qualification open items as identified in the Open Item Resolutien Plans included in our response to I' Bulletin 79-01B submitted on Sep'. ember 5, 1980. We expect to identify any necessary additional testing by early next year.

Sincerely, L ud Bar t D. Withers Vice President liuclear c:
