June 25, 1979 Trojan Nuclear Plant Docke t 50-344 License NPF-1 Lict.nse Change Application 51 Director of Nuclear Reactor Regulation ATTN:
Mr. A. Schwencer, Chief Operating Reactors Branch #1 Division of Operating Reactors U.S. Nuclear Regulatory Commission Washington, D. C. 20555
Dear Sir:
Mailed sepe.rately on June 20, 1979 were 40 copies of Topical Report PGE-1022, Inservice Testing (IST) Program for Pumps and Valves, in support of our License Change Application 26.
This Topical Report is provided in accordance with 10 CFR Part 50, Section 30.55a(g). The Inservice Testing Program for Pumps and Valves is in compliance with the American Society of Mechanical Engineers (ASME), Boiler and Pres-sure Vessel Code,Section XI, as referenced by 10 CFR 50.55a(g) through the 1977 edition and addenda through the Sum =er of 1978. Those places where relief or exe=ptions are requested are identified in this Topical Report.
Since the next 40 onth period for our IST Program commences on September 20, 1979, we would appreciate your prompt review and issuance of the requested license amendment.
If you have any questions regarding this document, please do not hesitate to contact us.
The next 40 month period for the Inservice Inspection (ISI) Program also begins on September 20, 1979. Our existing 10 yr ISI plan 1 currently being revised based upon the experience obtained during the 1
40-month inspection period. We are attempting to integrate als
..<e da ta and experience obtained into the new program prior to submitting it.
Additionally, we are reviewing the option of revising our committments to include the 1977 edition and addenda through the Summer of 1978 based upon your transmittal of the proposed change to 10 CFR 50.55a(g). Our initial impression is that we can make the transition to this newer code, but due to the numerous changes which have taken place between the two editions, the review of the additional requirements imposed by this code 282 25.4
- l 6/ d 7007030Y
JSP.
Mr. A. Schwencer June 25, 1979 Page Two requires extensive engineering analysis and study. We hope to have co=pleted at the time of submission our evaluations in order to apply the code that is most practical for both economic and safety reasons.
As a result, the revised ISI Program for the next 40 conth period will not be ready for submittal for some tice (i.e., 30-60 days). However, since we do not expect to be performing any inspections until the next refueling outage in early 1980, this delay abould not effect a rcview and approval schedule prior to its needed implementation.
Sincerely, "f
