CONNECTICllT YANKEE ATOMIC POWER ) Docket No. 50-213 COMPANY )

1 (Paddam Neck Plant) i EXEMPTION I.

Conn cticut Yankee Ato.mic Power Comnany (the licensee) is the holder of

~

. F_acility Operating License No. DPR-61 which authorizes the operation of the ,

Paddam Neck Plant (the facility) at the steady-state power levels not in excess of 18P5 mecewatts thernal~. The facility;11,a pressurized wateAreactor located at the licensee's site in Middlesex County, Connecticut. ThelIc'ense provides, among other thinos, that it! is sub.iect to all rules, regulations and Orders of the Nuclear Regulatory Commission (the Commissioni now or hereafter in effect.

.. II.

Section 50.71(e)(3)(ii).0,f 10,CFR Part 50 requires that those plants initiallysub.iectt[theNRC'ssystematicevaluationprogram(SEP)mustfile 4

a complete upda-ted final safety analysis report within P4 months after receipt

. o' notificatior! that the SEP has been_ completed. By letter dated July 20, 1983, the staff informed Connecticut Yankee Atomic Power Company (CYAPCo) that tne SEP had been completed for the Haddan Neck Plant and that, pursuant to 10 CFR 50.71(e)(3), the licensee was required to file ar updated Facility 8504250299 DR 850411 ADOCK 05000213 PDR

Descriotion and Sa#ety Analysis (FDSA). By letter dated February 4, 1985, the licensee requested an exemption to defer submittal of the updated FDSA on the bases that ongoing reviews would directly affect the content of the updated '

FDSA and that the required submittal would affect the work o# the licensee's engineering personnel ~on issues of higher safety significance.

The NRC staff has reviewed the licensee's request for an exemption from the Haddam Neck updated FDSA submittal date. For most plants covered by 10 CFP.

50.71 (el(3)(ii), anple. tim'e was available for updating the FDSA within the 24 6onth interval allowed in the regulations. However, the Haddam Neck Plant ~

recuested participation in an_ expanded assessment of outstanding regulatory

~

recuirements with the idea of estab1'ishing an intibrated schedule for The.

conoletion of these issues in a resource efficient nanner.

In addition the licensee has other ongoing activities which would directly affect the auality and substance of an updated FDSA. For example, CYAPCo is contracting with Westinghouse to develop and document detailed in#ormation on the decian and licensing bases for key systems at the Heddam Neck Plant. CYAPCo.has undertaken an extensive design bases reanalysis hihich will result in new analyses for all FDSA Chapter 10 transients and accidents and for several SEP topics. The licensee believes that these additional efforts will facilitate a*better understanding of the plant design bases when the updated FDSA is subnitted. -

The staff is also implementing a limited Integrated Safety Assessment Progran (ISAP) for the Haddam Neck Plant. Because the licensee had placed the updating of its FDSA into its original integrated assessment proposal, the staff will be reviewing that licensing action as part of its screening review of ISAP related topics. The Commission has authorized the staff in its policy statement on ISAP (49 FR 45112), to suspend specific existing implementation schedule requirements for plants to be reviewed under ISAP.

However, the staff bel'ieves that a current FDSA is a vital and.necessary

. fool in documenting the design bases of safety systems at the Haddam Neck ~~~

Plant as well as establishing the bases for future plant modifications and changes to technical specifications. WhileHaldaENeckhasshowngoo7 pause for_the requested exemption, the staff has determined that only a 6 month exemption from compliance with 10 CFR 50.71 is warranted at this time. Any additional exemptions from compliance from 10 CFR 50.71 will be granted by the Director of Licensing only upon review and approval of a program plan containing comprehensive schedules or milestones for the submittal of an updated FDSA for the.Haddam Feck Plant.

The NRC staff considered safety aspects of the requested exemotion from the updated FDSA submittal date. The proposed exemption affects only the reouired date fo~r updating the-FSAP and does not affect the risk of facility accidents. Thus, the granting ~of the requested exemption will have no significant impact on plant safety.

III.

The public interest will be served by. granting the exemption since the licensee can continue to use its personnel to complete other work of higher safety significance sooner than would be the case if personnel were diverted to update the FDSA immediately.

Based on its review, the staff concludes that issuance of this exemption will have no significant effect o'n plant safety. Further, this action.is in

~

~

the public interest and good cause-has been shown to support the exemption.

Therefore, a 6 month exemption from.the date of issuance of this exemption is

. : . +

being granted by the staff for the submittal of an updated FDSA for the -

Haddam Neck Plant.

Pursuant to 10 CFR 51.32, the Commission has determined that the granting of this exemption will have no significant impact on the environment (50 FR 13433, April 4, 1985).

~

Accordingly, the Commission has determined that, pursuant to 10 CFR

~

50.12,'an exemption is authorized by law and will not endanger life or

~

property or the common defense.and security and is otherwise in the public interest. Therefore, the Commission hereby approves the following temporary exemptionfromcompiiancewith50.7I(e).

An updated FDSA containing those original pages of'the FDSA that are still applicable plus new replacement pages shall be filed on or before a date 6 months from the date of issuance of the exemption. This updated FDSA shall bring the

S.

FDSA up to date as of a maximum of 6 months prior to the date of filing the uodated FDSA, with subsequent revisions no less frequently than annually thereafter. Any additional exemptions from compliance with 10 CFR 50.71 will be granted by the Director of Licensing only upon review and approval of a orogram plan containing comprehensive schedules or milestones for the submittal of an updated FDSA for the Haddam Neck Plant.
