7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION UNION-ELECTRIC COMPANY DOCKET NO. E0-483 NOTICE OF CONSIDER l.:.ON OF ISSUANCE OF AMENDMENT TO FACILITY OPERATING LICENSE, PROPOSED NO SIGNIFICANT HAZARDS CONSIDERATION DETERMINATION, AND OPPORTUNITY FOR HEARING The U.S. Nuclear Regulatory Commission (the Comission) is consi-dering issuance of an amendment to Facility Operating License No.
NPF-30,issuedtoUnionElectricCompany(thelicensee),foroperation of the Callaway Plant, Unit No. I located in Caltaway County, Missouri.
The_ amendment would correct the Callaway Technical Specification (TS) Surveillance Requirement 4.8.1.1.2.F.(2)' by deleting the reference tc.a value " greater than or-equal to.1352 kW" as a criterion for an acceptable emergency diesel. generator (EDG) load rejection test. - That value was derived from siziag design calculations and is not represen-tative of the largest single load on the diesel under design basis conditions. The revised ruiuirement'would reflect the criteria that' have been uced to demonstrate the capability of the EDGs to withstand-the rejbetion of the largest. load; namely, that voltage-and frequency can be maintained within specified limits.
The proposed' amendment is necessary in order to bring the current surveillance test into full, literal compliance with the TSs. The tests as conducted have been consistent with the licensing basis for the facility and have conformed with NRC Regulatory Guides 1.9 and 1.108.

Before issuance of the proposed license amendment, the Comission will have made findings required by the Atomic Energy Act of 1954, as amended (the Act) and the Comission'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 probaDility or consequences of an accident previously evaluated; or (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety.
The licensee nas provided an evaluation indicating _that the proposed change does not 'ny'lve a significant hacards consideration under the Comission's regulations in 10 CFR 50.92 as follows:
The proposed change does not involve a significant hazards con-sideration because operation of Callaway-Plant _ in-accordance with this change would not:
(1)
Involve a significant increase in the probability or con-sequences of an accident previously evaluated.
TheIloa rejection surveillance test in' question is taken from Regulatory Guide 1-.9, Revision 1, Position C,5 and Regulatory Guide 1'.108,; Revision.1, Position C.2.a.(4) which call for a test of the loss 1
of the largest single load. This surveillance test is performed at Callaway by disconnecting an ESW pump motor with the ESW and AC power m
___.___ _.___.___._ _ _.._ _ _ _ _ _ _m m.-
systems aligned in their emergency operation modes.
Currently there is no direct way to assure that this rejected load equals the 1352 kW listed in'the Technical Specifications. However, the actual kW load associated with the ESW pump motors-is less than 1352 kW and can vary slightly depending on plant conditions and motor efficiency. This Variance is insignificant as assured by the preventive maintenanca program that monitors pump / driver performance. Therefore, there should
-be no listed value for this load in the Technical Specifications nor is one needed to satisfy the regulatory guide requirements.
The intended requirement is to assure that the diesel meets the specified acceptance criteria given the. rejection of the ESW pump motor load when the plant is in a lineup representative of emergency conditions at Callaway.
No new design requi ements are being imposed on any plant systems or components.
There is no change to the 12 second diesel ; tart time assumed in the accident analyses and verified by Technical Specification 4.8.1.1.2.a.(4) nor is there is a change to the acceptance criteria for any of the diesel-generator surveillance tests, including the startup, rated load, and load rejection tests.
There will be. no effect on the capability of the diesel generators to supply the loads assumed in the mitigation of-the accidents analyzed in FSAR Chapte: 15.
.(?) Create the possibility of 9 new or different kind of accident from any previous.ly-evaluated.
The proposed change does not involve a.y design changes or hardware modif.ications nor will there be'any changes to the intended manner
+
of plant operation or in the method by which any safety-related plant -
- system performs its safety function.
No new accident initiators,
.~
-4 transient precursors, failure rechanisms, or limiting single failures are introduced as a result of this change.
(3)
Involve a significant reduction in a margin of safety.
The requirement to test for the loss of the single largest load will continue to be satisfied given the approval of this anendment application. The proposed change does not alter the manner in which safety limits or limiting safety system settings are determined. The proposed change will have no effect on those plant systems necessary to assure the accomplishment of protection functions and meet the accident analysis acceptanto criteria in FSAR Chapter 15.
There will be no impact on DNBR limits, F, F-delta-h, LOCA PCT, or any other defined g
safety margin.
The NRC staff has reviewed the licensee's analysis and, based on this review, it appears that the three standards of 10 CFR 50.9?(c) are satisfied.
Accordingly,. the Commission proposes to determine that this change does not involve a significant hazards consideration.
The Commission is seeking public ccm.nents on this proposed deter-mination.
Any couments received within fif teen (15) days af ter the date of publicat' ion of this notice will be considered in making any final 6etermination.
The Cor.nission will not normally make a final determination unless it receives a request for a hearing.

The filing of f
requests for hearing.and petitions for leave to intervene is discussed
- below.
By December 27, 1991
, the licensee may file a request for a hearing wit." respect to issuance of the amendment to the subject facility operating license and any person,fnose interest may be affected
-by this proceeding and who wishes to participate as a party in the proceeding must file a written request for hearint and a petition for
. leave to intervene.
Requests for a hearing and petitions for leave to intervene shall be filed in accordance with the Connission's " Rules of

Interested persons should-consult a current copy of 10 CFR f 714 which is available at the Comnission's Public Document Room, the Gelman Building, 2120 L Street, N.W., Washington, D.C. 20555 and at the 1.ocal-Public Document Room located at the Callaway County Public Library, 710 Court Street, Fulton, Missouri 65251, if a request for a hearing-or petition for leave to intervene is filed by the above date, the Connission or an l>
Atomic Safety and Licensing Board, designated by the Commission or by p
the Chairman of the Atomic Safety and Licensing Board Panel, will rule on the request and/or petition;- ano the Secretary or the designated l
..u..-.
e,
Atomic Safety 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 how that interest may be affected by the reselts of the proceeding. The petition should specifically explain the reasons I
why intervention should be permitted with particular reference to the following f actors:.(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 petit'oner's property, financial, or other interest in the proceeding; and (3) the possible effect of any order which rnay be entered in the proceeding on the petitioner's interest.
The petition snould also l
identify the specific aspect (s) of the subject matter of the pror.eeding as to which petitioner wir.hes to intervene. Any person who has filed a petition for leave to intervene or who has been admitt;? as a party may amend the petition without requesting leave of-the Board up to fifteen (15)-days prior to the first pre-hearing conference scheduled in the proceeding, but such an amended petition must satisfy the specificity requirements described above.
Not later than fifteen (15) days prior to the first preherring conference scheduled in the proceeding, a petitioner shall file a supplement-to the petition to intervene, which must include a list of
- the contentions that 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
- - 7..
provide a_brief explanation of-the bases of the contention and a concise statement of the alleged facts or expert opinion wh'ich support i
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 inust provide sufficient information to show that a genuine dispute exists with the applicant on a material issu'e of law or fact.
Contentions shall be limited to matters within the scope of the amendment under consideration. The contention must be one which, if_ proven, would entitle the petitioner to relief. A petitioner who fails to file such a supplement which satisfies these requirements with respect to at least one contention will not be
)
l permitted to. participate as a party.
Those permitted to intervene become parties to the proceeding, subject to any limitations in the order granting leave to intervene, and have the opportunity to participate fully in the conduct of the L
hearing', including the opportunity to present evidence and cross-examine witnesses.
-If the amendment is issued before the expiration of 30-days, the i
Commission will make a final determination on the issue of no significant i
bazards considerations.
If_a hearing is requested, the final determination will serve to decide when-the hearing is held.
Ii If the final determination is that the amendment request involves a i
no significa". hazards consideration, the Connission may issue the i
i l
amendment and make it imediately effective, notwithstanding the request for a hearing. Any hearing held would take place after issuance of the amendment.
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.
Normally, the Comission will not issue the amendment until the expiration of the 15-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 15-day notice period, provided that its final determination is that the amendment involves no significant hazards considerations. The final determination will consider all public and State comments received.
Should the Commission take this action, it will publish in the FEDERAL REGISTER a notice of issuance. The Comission expects that the need to take this action will occur very inf requently.
A request for a hearing or a petition for leave to intervene must 4
be filed with the Secretary of the Comission, U.S. Nuclear Regulatory Commission, Washington, D.C.
