7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION C0CKET N0. 50-285 OMAHA PUBLIC POWER DISTRICT NOTICE OF GRANTING OF EXEMPTION FROM APPENDIX R TO 10 CFR PART 50 FIRE PROTECTION PROGRAM The U. S. Nuclear Regulatory Commission (the Commission) has granted an Exemption from certain requirements of Appendix R to 10 CFR Part 50 to Omaha Public Power Company (the licensee). The Exemption relates to the fire protection program for the Fort Calhoun Station, Unit No. I (the facility) located in Washington County, Nebraska. The Exemption is effective as of July 3,1985.
The Exemption waives certain reoufrements of Subsection III.G of Appendix R to 10 CFR Part 50 as follows: Certain cables in containment beneath the pressurizer need not have 20-foot separation and other cables in containment having at least 20-foot separation may have some intervening combustibles between them. An area-wide automatic fire suppression system will not be required for the intake structure and fire detectors around the pull boxes near the intake structures will not be required. Regarding the air compressor room, cables and components of redundant shutdown divisions need not be separated by a continuous 1-hour fire-rated barrier. A complete fixed fire suppression system will not be required in the electrical penetration room.
In regard to the switchgear room, redundant shutdown divisions need not be separated by a complete 3-hour fire-rated barrier.

f
., Lastly, an area-wide fixed fire suppression system will not be required for the control rocm. The Exenption is granted mainly on the basis that the existing fire protection, coupled with proposed modifications at Fort Calhoun, is the most practical method for meeting the intent of Appendix R and literal compliance would not significantly enhance the fire protection capability.
Detafis are provided in the Exemption.
The reouests for the Exemption comply with the standards and reouf rements of the Atomic Energy Act of 1954, as amended (the Act), and the Comission's rules and regulations. The Commission has made aporopriate findings as reovired by the Act and the Comission's rules and regulations which are set forth in the Exemption.
Pursuant to 10 CFR 51.32, the Commission has determined that the issuance of the Exemption will have no significant impact on the environment (50 FR 20156).
