~ Commonwealth Edison Company's (CECO) Nuclear fuel Services (NFS)

DJpartment has-been developing its ability-to perform Reload Nuclear >

Design-and Safety Analyses. The_NRC'has encouraged utilities to perform ~such analyses-and expects-CECO to'be an industry leader. In support of-that effort, CECO 1 submitted a. Topical Report for Neutronics Methods-for BHR Reload Design (Reference (a)). The'NRC has reviewed and approved.thefmethodology presented in the__ Topical Report

-(ReferenceL(g)).

.The_ Topical' Report and subsequent approval by the NRC,_ establishes CECozas a qualified user =of the General 11ectric (GE) neutronics

.hmthodology. The GE inethods are described. in the GESTAP-II (Reference ,

(d)).

. CECO-has=two fuel vendors for its three BHR stationst GE is the fuel supplier for-Quad Cities and LaShlie County Stations; Siemens (formerkily ANF)1is the fuel supplier for Dresden Station.

~

Due to the ,

differences between the GE and Siemens-neutronic methodologies.with p 1 respect. to the Critical Power correlation-and -the associated uncertaintles, CECO is currently not planning oa_ using the GE~ methods described in the~ topical report for neutronic licensing calculations for Dresden' Station.(which has Siemens - supplied fuel).

sThe current version of.Section 6.6 of both_LaSalle County and Quad Citle!' Technical- Specifications references NEDE-24011-P-A (Reference -

(d))Las the;only approved analytical methodology._.The_ proposed-

^ changes maintain NEDE-24011-P-A and-include CECO's Topical Report (including- Supplements .1 and .2). The_ proposed' changes-allow' CECO to

' perform the analyses necessary to determine the core operating !!mits

-for both LaSalle County _and. Quad CitiesLStations.

L BASIS OF REQUESTED AMENDMENT

, zThis~ amendment request is to add the CECO Topical Report, and its

. Supplements to Quad Cities and LaSalle County Stations' Technical Specifications in Section 6.6, which- describes the- approved analytical e

, _ methods-for developing theLlicensing_ values contained in the COLR

<This will: allow CECO to perform the neutronic licensing calculations

, Lfor Quad Cities:and laSalla County, Ceco demonstrated their capability to perform the neutronic analyses required for licensing, operation, testing dndLsurveillance of a BHR

-reload' cycle and_provided these results to the NRC for. review and.

concurrence. .The NRC reviewed and approved.the results contained in L the CECO. topical,and thus determined that the Topical is acceptable for referencing for future reload cycles (Reference'(g)).

,1111U".E ANALYSES ANG USES The analyses for pressurt:ation events, stability margins, and Loss of Coolant Accident (LOCA) will continue to be maintained by General Electric for LaSalle Cour.ty and Quad Cities Stations. CECO wi'1 ger.erate the future Core Operating Limits Reports (COLR) in accordance with Reference (d). The benchmarks provided in References (a), (b),

and (c) displayed that CECO's calculation of the thermal.-mechanical narameters will have no adverse effect on the validity of the cycle specific limits or associated calculations. In addition, CECO will generate the updates to the Core Monitoring software by the methodolegies described in Reference (d).

CEN RELOAD IMPLE14EN1AT10N SCllEDULE

.Because CECO is phasing in the process of reload design, an Interfacing Procedure with GE was developed for establishing responsibilities and communication protocol during the phase in process. The purpose of the Interfacing Proced'jre is to provide the guidelines for design related technical interactions between Ceco and GE and to provide detailed guidelines for the type of information, type of correspondence and schedule for interactions between CECO and GE.

The current schedule for phasing in CECO responsibility for reload desian is as follows:

(LNLTICYCLE SIARTDP_DME CECO _RESECMSLBILIIIES LaSalle Unit 2 April 1992 Performed all initial fuel Cycle 5 management. Performed neutronic licensing calculations in parallel with official GE calculations.

Quad Unit 1 November 1992 Performed all initial fuel Cycle 13 management. Hill perform all neutronic licensing calculations in parallel with official GE calculations. N111 develop Core Monitorir.g Code inputs in parallel with official GE inputs.

LaSalle Unit 1 Ja.uary 1993 Perform all initial fuel

-Cycle.6 management. Perform alI neutronic licensing calculations. Develop Core Monitoring Code inputs in parallel with official GE inputs.

Quad Unit 2 June 1993 Perform all initial fuel Cycle 13 management. Perform all neutronic licensing calculations. Tentatively develop Core Monitoring Code inputs.

CECO proposes to revise inhnical Specification Section 6.6 of Quad l C!ttes Units I and 2 a'id LaSalle County Station Units I and 2 to l include the CECO Topical Report NFSR-0085 and its supplements. The l proposed revisions for these amendments, which are identical, are presented in Attachment 0 and C for Quad Cities and LaSalle County, res,)ectively. .The proposed changes will allow CECO to perform the reload neutroric calculatfors for Quad cities and LaSalle Cot"ity Stations. CECO rec;uests that these amendments be issued by June 15, 1992. There are no other Technical Specification changes required.

SCHEDULE The normal reload development process requires a lead time of approximately six (6) months. Because LaSalle Unit 1 is scheduled to startup fnom a refuel outage in January 1993. CECc requests approval for both LaSalle County and Quad Cities Stations, by June 15, 1992 to facilitate the usage of CECO methodologies for Initiating the analyses necessary for LaSalle Unit 1. Reload 5. CECO considers this amendment to be purely administrative and hence, the June 15, 1992 date should provide sufficient time for NRC review. The first full utilizatior for the CECO methodology at Quad Cities is not scheduled for usage until June 1993.
