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 regarding your Differing Professional = Opinion (DPO) the McGuire Technical ~ Specifications on (TSs) have been completed'or are proceeding to an established resolution plan.
These actions have included:
(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 to the McGuire FSAR by the licensee's annual updates.
These are identified by Table 2 and are discusscd by Enclosure 2.
The licensee has stated that~
those changes to the FSAR identified in its letter 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,'
these reevaluations determined that no actions need be taken by the licensee.
s During these reevaluations the NRC staff has had the benefit of comments by an NRC contractor, the licensee :(who, in turn, reflected the results.of comments by Westinghouse) and the results of previous staff reviews.
DPO issues resolved by this further evaluation are identified'by Table 3 and are discussed by Enclosure 3.
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,
'(dated' April 1990).
~
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 results generally indicate that.the new STS have j
addressed'several of the DPO issues, while other DPO l
concerns need not be added to the'STS because they do.
j not qualify under the: Commission's TS: criteria or for.
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.
