SUBJECT:
NINE MILE POINT NUCLEAR STATION, UNIT NO. 2 - REQUEST FOR ADDITIONAL INFORMATION - AMENDMENT APPLICATION RE: ULTIMATE HEAT SINK TEMPERATURE REQUIREMENTS (TAC NO. MC0594)
Dear Mr. Katz:
The Nuclear Regulatory Commission (NRC) staff is reviewing the subject proposed amendment, requested by your application dated August 22, 2003. On October 24, 2003, we held a telephone conference with Mr. John Dosa, et al., of your staff, on comments we previously e-mailed to your staff (available in the Agencywide Documents Access and Management System under Accession No. ML032830009). Participants agreed that a formal request for additional information (RAI) be issued. Enclosed please find the RAI. Your staff agreed that it can respond before January 15, 2004.
If you have any questions, please call me at 301-415-1451.
Sincerely,
/RA/

REQUEST FOR ADDITIONAL INFORMATION NINE MILE POINT NUCLEAR STATION, UNIT NO. 2 AMENDMENT APPLICATION REGARDING ULTIMATE HEAT SINK TEMPERATURE REQUIREMENTS
Reference:
Letter, P. E. Katz of Nine Mile Point Nuclear Station, LLC, to Nuclear Regulatory Commission, August 22, 2003.
(1)
At worst-case current licensing basis conditions with an ultimate heat sink (UHS) temperature of 84 F, what temperatures are expected in the cooling system of the emergency diesel generators (EDGs), and what are the associated limits?
(2)
What is the peak suppression pool temperature following a main steam line isolation transient from 100% power coincident with a loss of offsite power assuming a UHS temperature of 84 F? Describe how the residual heat removal system heat exchanger tube plugging limit described in the submittal is administratively controlled.
(3)
The application is worded in such a way that it is not clear that analyses at the proposed UHS temperature of 84 F were performed for various systems and parameters. It appears that, in most cases, a conclusion of acceptability was based on margin at the current UHS temperature. Please verify that analyses were performed at the proposed higher temperature and that the conclusions in the application remain valid at the higher temperature for the following. Note, that there is no need to submit the analyses; simple statements that analyses were done would suffice.
- a. EDG building heating, ventilation, and air conditioning
- b. Control building safety-related area coolers
- c. The maximum post-LOCA peak suppression pool temperature
- d. Reactor building supply air cooler
- e. Reactor core isolation room unit coolers
- f. Turbine building closed loop cooling system.
