Haddam Neck Plant Millstone Nuclear Power Station, Unit Nos. I and 2 Generic letter 89-06 On April 12, 1989, the NRC Staff issued Generic Letter 89-06, "Ta Plan Item I.D.2--Safety Parameter Display System--10CFR50.54(f).'gAction This Generic Letter requested a response within 90 days of the date of the Generic Letter. Since Connecticut Yankee Atomic Power Company (CYAPCO) and Northeast Nuclear Energy Company (NNECO) did not receive this Generic Letter until May 12, 1989, the NRC Staff was contacted to request an extension for the submittal of our response 1989. This request was formally docketed on July 12,1989,(2yntil July 21,at the request of the Staff.

. Generic Letter 80-06 generally discusses the results of the Staff's evaluation of the implementation of safety parameter display systems (SPDSs) by various licensees / applicants. Enclosed with the Generic Letter is NUREG-1342, "A Status Report Regarding Industry Implementation of Safety Parameter Display Systems," dated April 1989. NUREG-1342 describes methods used by some I

licensees / applicants .to implement SPDS in a manner found acceptable by the NRC Staff. Additionally, NUREG-1342 documents design features that the NRC Staff has found unacceptable and gives the Staff's reasons for finding them unacceptable.

Generic' Letter 89-06 specifically states that the information in NUREG-1342 does not constitute new requirements and that the Supplement I to NUREG-0737 establishes SPDS requirements. We commend the NRC's effort to document- the l acceptability to the Staff of various licensees'/ applicants' implementation of

, the SPDS criteria found in Supplement I to NUREG-0737. Whenever NRC require-L ments are general . in nature, as is the case with SPDS provisions found in Supplement I to NUREG-0737, it may be beneficial to licensees to be aware of more detailed NRC guidance regarding potential acceptable means of meeting the more general requirements. It is our understanding, however, that the infor-mation contained in NUREG-1342 constitutes one of several means of meeting the SPDS provisions found in Supplement I to NUREG-0737. Accordingly, not meeting precisely the NRC positions contained in the informational NUREG-1342 does not imply that a licensee does not comply with the more general SPDS provisions found in Supplement I to NUREG-0737.

As requested in Generic Letter 89-06, we have reviewed the SPDSs for the Haddam Neck Plant and Millstone Unit .Nos. I and 2 taking into account the information in NUREG-1342. (Generic Letter 39-06 specifically excludes Millstone Unit No. 3 from consideration.) We have also completed the check-list contained in the Generic Letter for these three plants. As explained below, we believe the SPDSs for the subject plants meet the applicable requirements of Supplement I to NUREG-0737. We do not, however, agree with the characterization in Generic Letter 89-06 that Supplement I to NUREG-0737 establishes the "legel requirements" for SPDS. It is our understanding that the provisions of Supplement I to NUREG-0737 are not in themselves legally binding requirements.

Besides those provisions of Supplement I to NUREG-0737 contained in NRC regulations (e.g.,10CFR50, Appendix E), the only aspects of Supplement I to NUREG-0737 which are legally binding are those contained in the various confirmatory orders the NRC issued on this subject which confirm previously docketed commitments. If we did not commit to a certain aspect of Supple-ment I to NUREG-0737, or if a commitment was not confirmed in the subject orders, the provisions of Supplement I to NUREG-0737 are not legally binding.

The following statement taken from Section 1 of Supplement I to NUREG-0737 h particularly illustrative of this interpretation:

It is . . . not intended that either the guidance documents or the l fundamental requirements are to be considered to be legal require-ments at this time.

With respect to the implementation of SPDSs at the Haddam Neck Plant and }

Millstone Unit Nos. I and 2, significant correspondence has been previousiy submitted to the NRC Staff identifying the means by which the provisions of l

Supplement I to NUREG-0737 would be met. In addition, this docketed informa-  !

tion has been reviewed by the Staff. Where additional information was required to be submitted to support Staff review of our SPDSs, such informa-tion was previously provided. In the case of the Haddam Neck Plant, the Staff's review of our dgeted information resulted in the issuance of an ,

October 21, 1988 letter which documented the Staff's conclusions that '

CYAPCO had met.all of its commitments for the implementation of the SPDS and 1 that the Staff review of the SPDS was complete. In a similar fashion, Staff review of docketed correspondence led to the issuance of for the Millstone Unit No. 2 SPDS on February 12,1987.I4 Safety A moreEvaluation detailed history of past correspondence between CYAPC0, NNECO, and the NRC can be found .

in Attachment 1.  !

Based upon the information referenced in Attachment I and, in particular, the SPDS Safety Analysis Reports (SARs) for each plant which specifically identi- i fied the means by which we intended to comply with the provisions of Supple- '

ment 1 of NUREG-0737, CYAPC0 and NNEC0, on behalf of the Haddam Neck Plant and Millstone Unit Nos. I and 2, respectively, hereby certify pursuant to  ;

10CFR50.54(f) and the Generic Letter 89-06 request that our SPDSs meet the applicable requirements of Supplement I to NUREG-0737. This certification does not imply that our SPDSs fully meet all the positions contained in NUREG-1342. Although we have reviewed our SPDSs in response to Generic letter 89-06 and conclude that they are consistent with the majority of the positions provided in NUREG-1342, given the fact that the NRC states that NUREG-1342 does not contain new requirements, we believe the previously docketed information remains sufficient to establish compliance with the applicable requirements of Supplement I to NUREG-0737.

With respect to the above certification, we note that changes to our SPDSs may be implemented without NRC approval pursuant to 10CFR50.59. Although we certainly intend to fully compe with the applicable requirements of Supple-ment I to NUREG-0737, changes to our SPDSs that do not affect legally binding requi.+ements, as defined above, can be made fully consistent with the require-ments of 10CFR50.59.

' July 21, 1989 issued by: the NRC ' Staff on July 27,1985,(13) the Staff acknowledged that an SAR and an implementation plan had been submitted on March 25, 1985, and confirced that the SPOS would be fully operational prior to the start Cycle 8 or by March 25, 1987, whichever was later. On February 11,1986, zig i, the NRC Staff requested that NNEC0 provide additional information on the SPDS.

.In accordance dated July 31, 1986. with ig) request, NNEC0 provided the information in a letter As a result of telephone conversations with the

, Staff, NNEC0 elected to conduct additional testing of one of the types of d isolation devices used in the SPDS. The testing an results were described in a letter to the Staff dated October 24,1986.qige On February 12, 1987,III) the NRC Staff issued a safety evaluation for the Millstone Unit No. 2 SPDS. It was concluded that no serious safety questions were posed by the proposed SPDS and g'prefore the implementation of the SPDS could continue. On June 1, 1987,I NNEC0 documented that the SPDS at Millstone Unit No. 2 was declared fully operational on March 24, 1987.

Included in this letter were our comments on the NRC. Staff's safety evaluation dated February 12, 1987. In respongg)to our June 1, 1987 letter, the NRC Staff responded on June 18, 1987, nnting that our comments on the 1 February 12, 1987 safety evaluation did not change the Staff conclusion that no serious safety questions are posed by the proposed SPDS.
