December 17, 1979 Docket No. 50-155 Mr. David P. Hoffman Nuclear Licensing Administrator Consumers Power Company 212 West Michigan Avenue Jackson, Michigan 49201
Dear Mr. Hoffman:
By letter of August 31, 1979, you provided certain design criteria as requested by our Fire Protection SER of April 4,1979, for the following proposed modifications:
3.1.3 Fire Detection Systems; 3.1.4 Fire Pump Header; 3.1.13 Fire Barrier Penetrations; 3.1.23 Recirculation Pump Area Sprinklers; and 3.1.26 Protection of Reactor Depressurization System (RDS) Cables. We have reviewed these design criteria and find that: an adequate number and type of fire detectors will be installed in appropriate locations; hose connections and isolation valves will be provided to bypass breaks in the fire pump header; an adequate cable penetration fire stop design will be used; an appropriate water spray system will be installed for the recirculation pump oil hazard; and adequate barriers are being installed to protect RDS cables. Additionally, these modifications are being designed in accordance with appropriate NFPA standards. On this basis, we find that the design of these modifi-cations provides the protection we intended in preparing our SER.
Accordingly, we find the design criteria for these modificiitions to be acceptable.
Sincerely, 34 wv%
