C9&L Carolina Power & Light Company J AN 0'41988 SERIAL:
NLS-88-001 10CFR50, Appendix R United States Nuclear Regulatory Commission ATTENTION: Document Control Desk Washington, DC 20555 BRUNSWICK STEAM ELECTRIC PLANT, UNIT NOS. 1 AND 2 DC"~4T NOS. 50-325 6 50-324/ LICENSE NOS. DPR-71 6 DPR-62 FIRE ANALYSIS Gentlemen:
i Carolina Power & Light Company (CP6L) hereby submits the Brunswick Steam Electric Plant (BSEP) Probabilistic Fire Analysis for your review and approval. This analysis included the construction of a detailed computerized fire model for both BSEP units.
Each model was heavily based on plant-specific data.
A calculation of fire-related core damage frequency (CDF) was made for each unit based on this model.
The Company requests early review of this model to achieve the following:
1.
Confirm its use at BSEP as a tool in fire protection / risk reduction activities, 2.
Confirm the merit of the methodology for possible use at the other CP&L units.
In addition, CP&L is also providing the BSEP Fire Risk Analysis.
This analysis is an application of the fire model to identify actions needed to reduce fire-related CDP to an internal goal of 3E-5/ year.
It also evaluates the risk reduction of certain Appendix R modifications and indicates the value of probabilistic risk analysis in meeting the goals of regulatory requirements such as Appendix R.
The Company has identified four required Appendix R modifications that provide negligible risk reduction as well as additional administrative controls not required by Appendix R that provide further reductions in risk.
The Company may elect to file exemptions from certain Appendix R requirements that provide negligible risk reduction in order to free the resources needed to pursue the reduction in fire related CDP to the above stated goal.
These documents contain CP&L proprietary information.
Therefore, in accordance with 10CFR2.790, the Company requests that they be withheld from public disclosure, An affidavit attesting to this fact is included g,%
in Attachment 1.
