July 11, 2002 Mr. David L. Wilson Vice President of Nuclear Energy Nebraska Public Power District P. O. Box 98 Brownville, NE 68321
SUBJECT:
COOPER NUCLEAR STATION (CNS) - REQUEST FOR EMERGENCY PROCESSING OF PROPOSED LICENSE AMENDMENT REQUESTS FOR EMERGENCY CORE COOLING SYSTEM (ECCS) PUMP NET POSITIVE SUCTION HEAD (NPSH) REQUIREMENTS AND ULTIMATE HEAT SINK (UHS)
AND REACTOR EQUIPMENT COOLING (REC) WATER TEMPERATURE REQUIREMENTS (TAC NOS. MB2896 AND MB5123)
Dear Mr. Wilson:
This is in response to your letter dated July 3, 2002, in which you requested emergency processing of two license amendment requests submitted on July 30, 2001, and May 20, 2002, by the Nebraska Public Power District (NPPD). By letter dated July 30, 2001, you requested an amendment for the ECCS pump NPSH requirements and by letter dated May 20, 2002, you requested an amendment for the UHS and REC water temperature requirements.
In your letter of July 3, 2002, you provided the following rationale for your request for emergency processing of your two license amendment requests. You stated that the current situation at CNS satisfies the criteria for an emergency as outlined in Regulation 50.91(a)(5) of Title 10 of the Code of Federal Regulations (10 CFR) in that CNS Technical Specifications (TSs) 3.7.2 and 3.7.3 require a hot shutdown of the plant in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and cold shutdown of the plant in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> in the event the temperature of the Missouri River, the UHS for CNS, exceeds the TS temperature limit (90EF) or REC water temperature exceeds TS limit (95°F). You stated that this emergency situation is caused by environmental factors beyond the control of NPPD.
During the evening of June 30, 2002, the temperature of the Missouri River exceeded 85EF.
You indicated that taking the uncertainty of the permanent instrumentation into account, the plant staff must begin to take action at 87EF to place the plant in shutdown. You concluded that the combination of natural phenomena and the standard regulatory process (30-day public comment period for the NPSH amendment) could result in an unwarranted plant shutdown.
The regulation 10 CFR 50.91(a)(5) requires licensees to "explain why this emergency situation occurred and why it could not avoid this situation." Your letter of July 3, 2002, did not address why the emergency could not be avoided. Therefore, the NRC staff determined not to act on your request pursuant to 10 CFR 50.91(a)(5), as requested in your letter. However, the staff has also determined that for safe continued operation of CNS, the licensee and the Commission must act quickly, and the time does not permit the Commission to wait for the 30 days of comment period for prior public comment. Therefore, the staff is processing the two amendments concerned on an exigent basis outlined in 10 CFR 50.91(a)(6).
David L. Wilson If you have any questions, please contact Mohan Thadani at (301) 415-1476 or Robert Gramm at (301) 415-1302.
Sincerely,
/RA by Robert A. Gramm for/
