'he U.S. f'uclet* Pegulatory Cerrission (the Ccmnissicr) is c:nsidering issurn:e of an a endment to Frovisional Operating License No. DFF-21 issued to The Connecticut Light and Power Company, L'estern Massachusetts Electric Company and Northeast Nuclear Energy Company (the licensees), for operation of the Millstone Nuclear Power Station, Unit No.1, located in New London County, Connecticut.

.. The amendrent would revise the Technical Specifications to allow continuous reactor operation for a period up to 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> with containment oxygen concentration greater than d'- and drywell to suppression chamber differential pressure less than 1 psid. This amendment was requested in the licensee's application dated May 15, 1985. .

Before issuance of the proposed license amendment, the Comnission will have made findings required by the Atomic Energy Act of 1954, as arended (the Act);an'd the Commission's regulations.

The Cc,'issicn has rade.a proposed deter-inatico that the amendrent request involves no significant hazards consideration. Under the Ccamission's regulaticos in.10 CFR 50.92(c), this means that operation of the facility in acc0 & cs ud.th the pr:p0 sed amendre".t would r.ct (1) involve a sictificant

' Nrease in the e-eteoility or conse,quencas of an accicent creviously evaluated; or (2) create the possibility or a new or different kind of eccident fron any. accident previously evaluated; or (3) involve a significant reduction in a margin of safety.

. The proposed atendment would change the technical specifications to permit containment deinerting ard pressure eoualizatien with power reduction based on ALARA (worker radiative exposure) considerations. The change would allow dry <. ell entry, vFile at power, for visual inspection, equipment adjustments, and maintenance-necessary fer centinuous safe reactor operation. For this tyre cf activi y current technical soecifications recuire that the reactor te shut d:wn within the allcwed 2a-hour deinerting peried and' full" irerted within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after reactor startup. .The proposed change, therefore. -does not affect the time that the reactor could be operating without inerted containment or a 1 psid differential pressure between the drywell and

. suppression chamber. Elimination of an unnecessary plant transient reduces, thouch insignificantly, the probability of accident.

I' The licensee has evaluated the proposed technical specification changes

nd ha: detcrminec that they do nct represent a cignificant ha:ards centideration.

. Based on the cri_teria for defining a significant hazards consideration set-forth in 10 CFR 50.92(c), operation of Millstone Nuclear. Power Station, Unit 1 in accordance with the proposed amendment will not (1) involve a significant increase in the probability or consequences of an accident previously evaluated

-because l the overall time for reactor operation with deinerted containment remains

T urchanged frca the currently approved technical specifications; cr (2) create the 4

pcssibility.of a new or different kind of accident #rca any accident c reviously evaluated because the conditions for postulated accidents remain uncha nged from these orevic'usly evaluated; or (3) involve a significant reduction -in argin

!?#ety, because the p"ccesed changes do net affect the previcusly evaluated safety margins. Besed on the above, the staff therefore proposes that_the arendnent request. involves no significant hazards consideration.

The Comnission is seeking public comments on this proposed determination.

. Any enements received within 30 days after the date of publication of this .

notice' will be considered in making any final determination. The Commission will not normally make a final determination unless~ it receives a reauest for a hearing.

Comments should be addressed t.o the Secretary of the Commission, U.S.

Nuclear Reculatory Corrissier, Vasnington, D.r. 40R:c,

By June 24, 1985 , the licensee may file a request for a hearing with respect to issuance of the amendment to the subject facility operating

. license and any person whose interest may be affected by this proceeding and who wishes to participate as a party in the proceeding must file a written petition for leave to intervene. Request for a hearing and petitions for

. leave to intervene shall be filed in accordance with the Connission's " Rules of Practice for Domestic Licensing Proceedings" in 10 CFR Part 2. If a reauest for a hearing or petition for leave to intervene is filed by the above

• e L.m

r-4-

c:te, the Cc=ission or an Atcmic Safety and Licensing Board, designated by the Ccmission or by the: Chairman of the Atomic Safety and Licensing Board Fanel, will rule on the request and/or petition and the Secretary or the cd ignated Atsmic' Safety and Licensin'; Board will issue a notice cf hearing or

nereprit e e-der. .

-As required by 10 CFR 92.714, a petition for leave to intervene shall set forth with particularity the interest of the, petitioner in the proceeding, anc hcw that interest may be affected by the results of the proceeding. The

- petition should specifically explain the reascns why intervention should be permitted with particular reference to the following factors: (1) the nature of the petitioner's right under the Act to be made a party to the proceeding; (2) the nature and extent of the petitioner's property, financial, or other interest in the croceeding; and (3) the possible effect of any orcer which may be entered in the proceecing on the petitioner's interest. The petition shculd also identify the specific. aspect (s) of the subject natter cf the proceeding as to which petitioner wishes to intervene. Any person who has

-filed.a petition for leave to intervene or who has.been admitted as a party may amend the petition without requesting leave of the Board up to fifteen (15) days' prior to the first prehearing conference scheduled in the proceeding, but,such an amended petition must satisfy the specificity requirerents described above.

Not later tnan fifteen (15) days prior to the first prehearing conference scheduled in the proceeding, a petitioner shall file a supplement to the pet'ition to intervene which must include a list of the contentions which are scught to be ~ litigated in the matter, and the bases for each contention set o

p-

- forth with reasonable specificity. Contentions shall be limited to matters within the scope of the amendment under consideration. A petitioner who fails to file such a supplement which satisfies these requirements with respect to at least one contention will not be permitted to participate as a party.

Th0se permitted to intervere becere parties to the ::recseding, rubject t0 any limitations in the order granting leave to intervene, and have the

. opportunity to participate fully in the conduct of the hearing, including the opportunity to present evidence and cross-examine witnesses.

If a-hearing is requested, the Commission will make a final determination -

.on the issue of no significant hazards consideration. The final determination s

will serve to decide when the hearing is held.

-If-the final determination is that the amendment request involves no significant hazards consideration, the Commission may issue the amendment and make it effective, notwithstanding the request for a hearing. Any hearing held would take place after issuance of the amencment.

If the final determination is that the amendment involves a significant hazards consideration, any hearing held would take place before the issuance of any amendment.

Normally, the Commission will not issue the amendment until the expiration of the 30-day notice period. However, should circumstances change during the notice period such that failure to act in a timely way would result in derating or shutdown of the facility, the Comission may issue the license amendment-before the expiration of the 30-day notice period, provided that its' final determination is that the amendment involves no significant hazards 4

censideration. The final determination will consider all public and State ccmments received. Should the Commission take this action, it will publish a

~

notice of. issuance and provide for opportunity for a hearing after issuance.

-The Cc=,ission expects that the need 'to take this acticn will occur very infre u ntly.

A request for a hearing or a petition for leave to intervene must be filed with.the Secretary of the Commission, U.S. Nuclear Regulatory Cerission, Washington, D.C. 20555, Attn: Docketing and Service Branch, or

- may-be delivered to the Commission's Public Document Room,1717 H Street, N.W. .

Washington, D.C., by the above date. Where petitions are filed during the last ten (10) days of the notice period, it is requested that the petitioner promptly so inform the Commission by a toll-free telephone call to Western Union operater at (800) 325-6000 (in Missouri (E00) 342-6700).
