SUBJECT:

Nine Mile Point Unit 2 Emergency Action Levels Revision Based on NUMARC NESP-007 In accordance with the guidance provided by the NRC staff at recent NEI meetings, Niagara Mohawk is submitting for review and approval the enclosed Emergency Action Levels (EALs) for Nine Mile Point Nudear Station Unit 2. Niagara Mohawk, in accordance with 10CFR50,54 (q), has reviewed these EALs and determined that they represent an enhancement to the Nine Mle Point Emergency Plan, The EALs have been revised consistent with the NUMARC NESP407 methodology, and were developed as part of a joint project with all nudear utilities within New York State. In order to assist your review we have included a number of developmental documents in the endosed EAL Generation Package.

The EAL Generation Package consists of the following:

~ Plant-Specific EAL Guideline ~ EAL Technical Bases

~ Fission Product Barrier Evaluation ~ Emergency Action Level Matrix

~ EAL Binning Document ~ Validation and Verification Report Attachment 1 provides an explanation of the contents of the EAL Generation Package.

These EALs were developed as a joint project with the New York Power Authority, Consolidated Edison, Rochester Gas and Electric, and Niagara Mohawk. This process ensures consistent emergency classification between all New York State nuclear utilities to the greatest extent possible, limited only by plant design differences. We believe that a coordinated review of all the New York State nuclear utility EAL revisions willpromote this consistency and willresult in the most advantageous use of time and resources.

Please contact Ms. Coleen Ware, Director of Emergency Preparedness, at 349-2066 should you have any questions or require additional information regarding this matter.

Very truly yours, c

M . McCormick, Jr.

SUMMARY

INTRODUCTION Prior to the acceptance by the NRC of NUMARC/NESP-007 "Methodology for Development of Emergency Action Levels" as an acceptable alternative to the NUREG 0654 EAL guidance, the four nuclear utilities in the State of New York decided to perform a joint implementation of the new methodology. This upgrade project involved the following plants:

Nine Mile Point Unit 1 (NMP1) - Niagara Mohawk Power Corporation Nine Mile Point Unit 2 (NMP2) - Niagara Mohawk Power Corporation James A. FitzPatrick Nuclear Power Plant - New York Power Authority Indian Point Station 2 - Consolidated Edison Indian Point 3 Nuclear Power Station- New York Power Authority R. E. Ginna Nuclear Power Station - Rochester Gas and Electric While the resulting upgraded EALs are site specific, an objective of the upgrade project was to ensure conformity and consistency between the sites to the extent possible.

The following paragraphs describe the site specific EAL developmental documents which are included in the EAL review package.

~ ~

1 The PEG is the NMP2 Interpretation of the NUMARC methodology for developing EALs. The PEG identifies deletions from the NUMARC methodology by striking out words and phrases that are not applicable, additions are identified by underlining new words and phrases. The documents which provide the basis for these changes from NUMARC methodology are listed in the references section of the PEG.

i nP B 'r vl i The FPBE contains the evaluation of the NUMARC example EALs for each of the three fission product barriers. The result of this evaluation is a discrete set of quantifiable EALs which represent the NUMARC fission product barrier loss matrices.

, ~

Based on the number o example EALs, and the number o oss and potential loss conditions, the set of conditions that can yield a given emergency classification can be determined. An evaluation of each condition or set of conditions was made to determine if it properly defines the appropriate threshold for the dassification. If a condition or set of conditions was appropriate, a comment reflecting this conclusion was recorded in this document, If a condition or set of conditions is determined to be inappropriate, it is lined out and the reason for this conclusion is similarly recorded.

P2E LB Since the format presented in NUMARC/NESP-007 is inadequate for implementation; the EALs.defined-by-the.PEG-and FPBE-must be binned into categories and subcategories which support ease of use. The binning document identifies where each PEG/FPBE Initiating Conditions (IC) is addressed within the presentation scheme, NMP2 EAL Technical Bases Document The EAL Technical Bases Document provides an explanation and rationale for each of the emergency action level (EALs) included in the EAL Upgrade Program.

It is also intended to facilitate the review process of the NMP2 EALs and provide historical documentation for future reference. This document is also intended to be used by those individuals responsible for implementation of the NMP2 dassification procedure as a technical reference and aid in EAL interpretation.

NMP2 Emer en A ion Level Matrix The Emergency Action Level Matrix is the user level result of the EAL development project. This matrix will be incorporated in the Emergency Plan Implementing Procedures and is used directly by operations personnel to classify an event.

P2V r' li i The NMP2 Verification and Validabon Report documents the process conducted to verify and to validate the site specific EALs and supporting documentation, This document also includes the comments received during validation along with comment resolutions.

The verification process was performed to ensure the NMP2 EALs and classification procedures are technically correct. The NMP2 EAL verification was conducted prior to the EAL validation exercises. The technical accuracy of the upgraded EALs were verified through tabletop reviews.

, 0 The validation process sures that the NMP2 EALs and c assification procedures are usable and correct, and ensures that emergency response personnel are able to arrive at consistent interpretations of EALs under similar conditions. The EALs were validated through observation of emergency response organization personnel responding to simulated emergency events. The group of EALs selected for validation were sufficiently representative of all the EALs.
