Subject:
Second Ten-Year Interval Pump and Valve Testing Program for I
Davis-Besse Nuclear Power Station Unit 1 (TAC Number M76025)
Gentlemen:
By letter dated March 22, 1990, (Serial Numbex 1776) Toledo Edison (TE) submitted the subject Pump and Valve Testing Program for Davis-Besse Nuclear Power Station Unit 1 (DBNPS) to the Nuclear Regulatory Commission. The
- p program was updated in accordance with 10 CFR 50.55(g)(5)(1) to be applicable for the second ten-year in-service inspection and testing interval. The: Pump and Valve Testing Program incorporates the 1986 Edition of the American I
Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, which is the most recent edition incorporated by reference in 10 CFR 50.55(a)(b).
{
The second ten-year interval vill begin on September 21, 1990.
j The scope of the pump and valve inservice testing program-includes safety-related pumps and valves required to (1) shutdown the reactor to the safe shutdown condition; (2) maintain the reactor in the safe shutdown j!
enditions or (3) mitigate the consequences of an accident. The safe shutdown condition for the DBNPS, as licensed, is the hot standby condition defined by the Operating License Appendix A Technical Specifications. Toledo Edison considers that this scope encompasses those pumps and valves whose function is required for safety, consistent with 10 CFR 50.55a(g)(4)(11).
3 Toledo Edison recognizes that Section XI, Article IVV-1100 of the 1986 edition of the ASME Code, vould include valves which are required to perform a specific function in shutting down the reactor to the cold shutdown condition.
A general relief request from Article IVV-1100 is included in the program for' the purpose of identifying this difference in scope between the 1986 edition of ASHE Code and the DBNPS licensing basis.

s Docket Number 50-346 Lic:nso Nu;ber NPF-3 S rial Nu:ber 1838 Page 2 F.'nce the program was eubmitted on March 22, 1990, subsequent review has identified the need for changes to the program as originally submitted.
Table 1 identifies the location and nature of t.he program chsnges. The most substantial change is an expansion of program scope to include additional makeup system components which are credited by the Updated Safety Analysis Report in mitigating the consequences of a tornado.
The program includes requests for rellef from certain ASME Seetion XI pump and valve testin..equirements. The program includes both new relief requests and relief requests which vare approved for the first ten-year interval.
As a q
result of program expansion, prsviously approved relief requests have been applied to components which have been added to the program.
In some cases, previously approved relief requests have been modified to reflect experier.ce gained during the first ten-year interval.
Because the program is organized by system, requests for relief from the same k
ASME Code Section XI requirements are repeated in each section of the program where applicable.
Deferment of check valve testing from quarterly to each refueling, for example, represents the most videly applied relief request.
Table 2 summarizes the relief requests for pumps by specific ASME Code requirement. Table 3 summarizes relief requests for valves by specific ASME Code requirement.
These tables ident'.fy specific Code requirements, applicable components, Pt.ID references, and the program location where system
[
specific relief justification can be found.
These tables are intended to facilitate NRC review of relief requests required for implementation of the program.
As discussed in a telephone conference with the NRC Staff on July 26, 1990, Toledo Edison understands that the NRC Staff intends to perform an initial review of the relief requests with a goal of granting interim approval where justification appea.s to be adequate by September 21, 1990, the program implementation date, pending completion of a detailed reviev.
Toledo Edison also underst. ands that the NRC Staff prefers that the updated program be implemented on September 21, 1990, even if the requested relief has not been granted. Updated programs are generally considered to be more comprahensive and an improvement over previous programs.
Should you have any questions regarding this updated in-service testing program, please call Mr. R. V. Schrauder, Manager - Nuclear Licensing, at i
