l UNITED STATES NUCLEAR REGULATORY COMMISSION j
NORTHERN STATES POWER COMPANY DOCKET NO. 50-263 NOTICE OF CONSIDERATION OF ISSUANCE OF AMENDMENT TO FACILITY OPERATING LICENSE. PROPOSED NO SIGNIFICANT HAZARDS CONSIDERATION DETERMINATION. AND OPPORTUNITY FOR A HEARING The U.S. Nuclear Regulatory Comission (the Comission) is considering issuance of an amendment to Facility Operating License No. DPR-22 issued to the Northern States Power Company for operation of the Monticello Nuclear Generating Plant located in Wright County, Minnesota.
j The proposed amendment would revise Technical Specification (TS)
Section 4.7, " Surveillance Requirements for Primary Containment Automatic Isolation Valves." Specifically, the proposed amendment would revise the replacement frequency of the seat seals for the drywell and suppression chamber purge and vent valves from every 5 years to every six operating cycles.
Before issuance of the proposed license amendment, the Comission will I
have made findings required by the Atomic Energy Act of 1954, as amended (the Act) and the Commission's regulations.
The Comission has made a proposed determination that the amendment request involves no significant hazards consideration. Under the Comission's regulations in 10 CFR 50.92, this means that operation of the facility in accordance with the proposed amendment would not (1) involve a'significant increase in the probability or consequences of an accident previously j
evaluated; or (2) create the possibility of a new or different kind of l

accident from any accident previously evaluated; or (3) involve a significant reduction in a margin f safety. As required by 10 CFR 50.gl(a), the licensee 1
l has provided its analysis of the issue of no significant hazards consideration, which is presented below:
i-r The oronosed amendment will not involve a sianificant increase in the orobability or conseauences of an accident oreviousiv evaluated.-
An evaluation of the operational performance of the 18-inch purge and vent valves has concluded that a change in the seat seal replacement frequency specified in Monticello Technical Specification surveillance requirement 4.7.D.4 will have no adverse impact on the seat leakage performance of these primary containment isolation valves, no adverse j-impact on the testing performed in accordance with 10 CFR 50, Appendix J, and thus no adverse impact on the containment isolation function of these primary containment isolation valves.
The material of which the T-shaped elastomer seat is comprised of has been found to withstand normal and accident thermal exposures for the design life of
{
the plant based on a thermal aging analysis.
Radiation effects will not have an adverse impact on the elastomer seat material. Therefore, this amendment will not cause a significant increase in the probability or consequences of an accident previously evaluated for the Monticello plant.
The oronosed amendment will not create the possibility of a new or different kind of accident from any accident oreviousiv analyzed.
The proposed change to the Technical Specifications for the Primary Containment Purge and Vent valves does not alter the function of these components or their interrelationships with other systems.
Therefore, this amendment will not create the possibility of a new or different kind of accident from any accident previously analyzed.
The oronosed amendment will not involve a sianificant reduction in the marain of safety.
The operating experience of these valves has demonstrated that the testing performed in accordance with 10 CFR 50, Appendix J, provides a high level of confidence in the ability of these valves to perform their safety function with respect to valve leak tightness. The proposed criteria for seat seal replacement provides added assurance that these containment isolation valves will perform the required safety function of containment isolation. The proposed amendment will not involve a significant reduction in the margin of safety.

The NRC staff has reviewed the licensee's analysis and, based on this review, it appears that the three standards of 10 CFR 50.g2(c) are satisfied.
Therefore, the NRC staff proposes to determine that the amendment request I
involves no significant hazards consideration.
The Commission is seeking public comments on this proposed l
' determination. Any comments received within 30 days after the date of publication of this notice will be considered in making any final f
determination.
l Normally, the Commission will not issue the amendment until the 5
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, for example, 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 consideration. The final determination will consider n11 public and State comments received. Should the Comission take this action, it will publish in the FEDERAL REGISTER a notice of issuance and provide for opportunity for a hearing after issuance. The Comission expects that the need to take this action will occur very infrequently.
W:itten comments may be submitted by mail to the Rules Review and Directives Branch, Division of Freedom of Information and Publications Services, Dffice of Administration, U.S. Nuclear Regulatory Comission, Washington, DC 20555, and should cite the publication date and page number of this FEDERAL REGISTER notice. Written comments may also be de' livered to Room 6022, Two White Flint North,11545 Rockville Pike, Rockville, Maryland, from
. 4 7:30 a.m. to 4:15 p.m. Federal workdays. Copies of written comments received may be examined at the NRC Public Document Room, the Gelman Building, 2120 L Street,NW., Washington,DC.

The filing of requests for hearing and petitions for leave to intervene is discussed below.
By April 8,1996, 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 request for a hearing and a petition for leave to intervene. Requests for a hearing and a petition for leave to intervene shall be filed in accordance with the Commission's " Rules of Practice for Domestic Licensing Proceedings" in 10 CFR Part 2.
Interested persons should consult a current copy of 10 CFR 2.714 which is available at the Commission's Public Document Room, the Gelman Building, 2120 L Street, NW., Washington, DC, and at the local public l
document room located at the Minneapolis Public Library, Technology and Science Department, 300 Nicollet Mall, Minneapolis, Minnesota 55401.
If a request for a hearing or petition for leave to intervene is filed by the above date, the Commission or an Atomic Safety and Licensing Board, designated by the Commission or by the Chairman of the Atomic Safety and Licensing Board Panel, will rule on the request and/or petition; and the Secretary or the designated Atomic Lfety and Licensing Board will issue a notice of hearing or an appropriate order.
As required by 10 CFR 2.714, a petition for leave to intervene shall set forth with particularity the interest of the petitioner in the proceeding, and
i how that interest inay be affected by the results of the proceeding. The petition should specifically explain the reasons 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 party to.the proceeding; (2) the nature and extent of the petitioner's property, financial, or other interest in the proceeding; and (3) the possible effect of any order which may be entered in the proceeding on the petitioner's interest. The petition should also identify the specific aspect (s) of the subject matter of 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 15 days prior to the first prehearing conference scheduled in the proceeding, but such an amended petition must satisfy the specificity requirements described above.
Not later than 15 days prior to the first prehearing conference scheduled in the proceeding, a petitioner shall file a supplement to the petition to intervene which must include a list of the contentions which are sought to be litigated in the matter. Each contention must consist of a specific statement of the issue of law or fact to be raised or controverted.
In addition, the petitioner shall provide a brief explanation of the bases of 1
the contention and a concise statement of the alleged facts or expert opinion which support the contention and on which the petitioner intends to rely in proving the contention at the hearing. The petitioner must also provide references to those specific sources and documents of which the petitioner is aware and on which the petitioner intends to rely to establish those facts or expert opinion.
Petitioner must provide sufficient information to show that a e
+-e-

i
{*,
genuine dispute exists with the applicant on a material issue of law or fact.
l Contentions shall be limited to matters within the scope of the amendment under consideration. The contention must be one which, if proven, would f
entitle the petitioner to relief. A petitioner who fails to file such a supplement wh'ich satisfies these requirements with respect to at least one i
contention will not be permitted to participate as a party.
d Those permitted to intervene become parties to the proceeding, subject l
to any limitations in the order granting leave to intervene, and have the opportunity to participate fully in the conduct of the hearing, including the l
opportunity to present evidence and cross-examine witnesses.
If a hearing is requested, the Comission will make a final determination on the issue of no significant hazards consideration. The final determination will serve to decide when the hearing is held.
If the final determination is that the amendment request involves no significant hazards consideration, the Comission may issue the amendment and make it immediately effective, notwithstanding the request for a hearing. Any hearing held would take place after issuance of the amendment.
l If the final determination is that the amendment request involves a significant hazards consideration, any hearing held would take place before the issuance of any amendment.
A request for a hearing or a pution for leave to intervene must be filed with the Secretary of the Comission, U.S. Nuclear Regulatory Commission Washington, DC 20555, Attention: Docketing and Se' vices Branch, r
or may be delivered to the Comission's Public Document Room, the Gelman Building, 2120 L Street, NW., Washington, DC, by the above date. Where
