Mr. A. Schwencer, Chief Licensing Branch No.
2 Division of Licensing Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, DC 20555
Dear Mr. Schwencer:
Re:
Nine Mile Point Unit 2 Docket No. 50-410 Enclosed is Revision 0 of the Emergency Procedure Guideline for Nine Mile Point Unit 2 which has been revised based upon Nuclear Regulatory Commission staff comments.
Also provided is a draft of the development, verification and validation procedures for your information.
These latter procedures are included as requested by the Nuclear Regulatory Commission staff to show evidence of the detailed methods used to ensure the accuracy of the Emergency Procedure Guideline.
Additionally, the Nuclear Regulatory Commission requested that we provide a commitment to revise Figure 7 of the Emergency Procedure Guideline.
Niagara Mohawk will revise Figure 7 and determine the primary containment pressure limit taking into account the ultimate containment pressure and consider the operability of the purge/vent isolation valves and the operability of the Automatic Depressurization System valves as part of the analysis.
Very truly yours, TEL/NLR:ja Enc losure cc:
