Vassallo, Chief Operating Reactors Branch No. 2 Division of Licensing United States Nuclear Regulatory Commissica Washington, DC 20555 BRUNSWICK STEAM ELECTRIC PLANT, UNIT NOS. 1 AND 2 DOCKET NOS. so-325 & 50-324/ LICENSE NOS. DPR-71 & DPR-62 NUREG-0737 ITEMS II.K.3.30/31

Dear Mr. Vassallo:

SUMMARY

In your letter of January 4, 1984, you stated that the NRC has accepted the General Electric small break loss of coolant accident (LOCA) model for use in satisfying NUREG-0737 Item II.K.3.30. You noted that this CE model was originally approved in a letter dated February 4,1981 as described in the GE Topical Report NEDO-20566, Revision 1 and Revision 4. You also noted that if this model was used in the LOCA analysis for the Brunswick Plant and was

, documented in the Updated Final Safety Analysis Report (FSAR), then NUREG-0737 Items II.K.3.30 and II.K.3.31 are considered complete.

DISCUSSION General Electric has notified the BWR Owners' Group that there are no Revisions 1 and 4 of NEDO-20566. The confusion is due to an error in the title of the cover letter from Mr. R. L. Tedesco (NRC) to Mr. G. G. Sherwood (GE), " Acceptance for Referencing of Topical Report NEDE-20566P, NEDO-20566-1, Revision 1, and NEDE-20566-4, Revision 4." This letter, which is the February 4,1981 letter referenced above, transmitted the NRC approval for:

(1) the base LOCA Nel described in NEDO- 20566, (2) Revision 1 of the Amendment 1 option to the base model, and (3) the Amendment 4 option to the model. NED0-20566-1, Revision I refers to Revision 1 of Amendment 1, and NEDE-20566-4 refers to Amendment 4. There is no Revision 4 to either the base adel or Amendment 4; therefore, the reference to NEDO-20566-4, Revision 4 is erroneous.

During a telephone conversation between Mr. D. L. Wigginton (NRC) and Mr. D.

K. Dennison (GE) on January 4,1984, the Staff stated that in order to satisfy NUREG-0737 Item II.K.3.31, a licensee need only identify to the NRC the reference on the docket to NEDO-20566 or NEDE-20566P (proprietary version) either in the final version or in the draft version of August 1974. On page 6.3R-1 of the Brunswick Updated FSAR, you will find referenced (Reference 6.3.3-2) " General Electric Company Analytic Model for Loss-of-Coolant-Analysis in Accordence with 10CFR50 Appendix K," NEDO-20566 (Draf t), subnitted August 1974. Theretuie, Carolina Power & Light Company considers NUREG-0737 Items II.K.3.30 and II.K.3.31 as complete for the Brunswick Plant.
