m L SEP 101990 l-Docket Nos. 50-369 and 50-370 MEMORANDUM FOR: Robert Licciardo, Planning, Program and Management Support Branch, PMAS Office of Nuclear Reactor Regulation FROM: Thomas E. Murley, Director Office of Nuclear: Reactor Regulation

SUBJECT:

CLOSURE OF DPO ISSUES REGARDING MCGUIRE TECHNICAL SPECIFICATIONS (TACS 55435/

55436/67757).

In accordance with my memorandum to you of December 29,'1989, the actions the McGuire regarding your ~Differing Technical Specifications Professional = Opinion (DPO) on (TSs) have been completed'or are proceeding have included: to an established resolution plan. These actions (1) Issuance of amendments to the McGuire operating-licenses changing TSs based on plant-specific issues.

The DPO issues resolved in this manner are: identified by Table 1 and are discussed-by Enclosure 1.

(2) Changes updates. to the McGuire FSAR by the licensee's annual discusscd byThese are identified Enclosure 2. by Table 2 and are those changes to the FSAR The licensee in identified has itsstated letter that~

of June 10, 1986, if not already made, arefbeing addressed by the "1989 update" to be issued-in September 1990..

(3) Reevaluations by SRXB and other technical branches: for several plant-specific issues. -Unlike item (1) above,'

s these by taken reevaluations the licensee. determined that no actions need be During these reevaluations the NRC staff has had the benefit of comments by an NRC contractor, the licensee :(who, in turn, reflected the results.ofstaff previous comments reviews. by Westinghouse) and the results of DPO issues resolved by this further evaluation discussed by Enclosureare 3. identified'by Table 3 and are The staff has also had the benefit of your further comments of June 19, 1990, on A. Thadani's memorandum CONTACT: D. Hood, PDII-3/NRR 49-20905 h

c L

SEP 101990l Distribution See_Next Page of May 14, 1990. -Where appropriate, these further:

comments have been addressed'in Enclosure 3 by adding' clarifications to the: prior resolutions of May,14, 1990 ~

'(dated' April 1990).

(4) Evaluation by OTSB of DPOs based upon generic' issues. . i Issues in this category were evaluated using criteria  ;

given in the Commission's Interim Policy Statement on -!

Technical-Specification Improvement tol determine if they '

should be incorporated.into the Standard Technical' Specifications (STS) for the Westinghouse Owners Group  !

(WOG). For this evaluation, OTSB .7d the benefit of i

extensive-support by NRR technical branches and information from WOG. These issues are identified by Tables- 4 and 5' and are discussed in Enclosure 4.: The j

results generally indicate that.the new STS have addressed'several of the DPO issues, while other DPO concerns need not be added to the'STS because they do.

not qualify under the: Commission's TS: criteria or for.

jl technical reasons.

1 The above actions have addressed all'DPO issues not previously closed by R. Bernero'a memorandum of August 30,'1984.-

Additionally, these previously closed issues (160 in.all) were reviewed in light of events at Diablo Canyon and Vogtle. ~ 'The review found that the original DPO issues regarding mid-loop operation have all been addressed throughEstaff considerations and actions in response to the Diablo Canyon event,Lincluding- 1 resolution of Generic-Issue 36A. . With respect to the Vogtle-event, none of the 160 issues included concerns regarding:' station blackout. Moreover, no reason to re-open anyJof the 160. issues i' was found during the review.

=Accordingly, this completes NRR action on your DPO and.the

~

subject TACS are closed.
