ENCLOSURE Supplement to the Fire Protection Safety Evaluation Report In the Ma+ter of Consumers P er Comoan_y Big Rock Point Plant Docket No. 50-155 3.2.2 Fire Brigade Our evaluation on the minimum required fire brigade shift size was sent to the licensee by letter of September 7,1979. Additionally, this requirement is now included in Appendix R to 10 CFR Part 50 which will become effective in the near future. We, therefore, expect that the licensee will conform to this requirement. Subject to conformance to this requirement, this item is satisfactorily reselved.
3.2.3 Cabling in the Recirculation Pumo _ Area Incomplete item 3.2.3 in our fire protection SER of April 4,1979, noted that the licensee was continuing to evaluate the need for providing fire protective thermal insulation on the cabling and valve operators for the emergency condenser return line valves in the recirculation pump area. By letter of June 15, 1979, the licensee provided the results of an evaluation of a fire in this area and concluded that additional protection was not required for the following reasons:
(1) the likelihood of a fire is small because the only significant flammable material in the area is the recirculating pump lube oil, this oil has a relatively high flash point and ignition temperature, and no ignition sources are present in the area of these pumps; (2) a directed water spray system is being provided on the recirculation pumps should a fire occur; (3) smoke detectors are located in this area and manual hose stations are available nearby; and (4) safe shutdown could be achieved using systems that would not be affected by a fire in the recirculation j
pumo area.
We have reviewed the licensee's evaluation and concur in the conclusions. We find that fire protection for this area con-I foms to the guidelines in Section 2.0 of our SER and is, therefore, acceptable.
