SUBJECT:
Nine MilePoint Unit 1 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 MilePoint Nuclear Station Unit 1. Niagara Mohawk, in accordance with 10CFR50.54 (q), has reviewed these EALs and determined that they represent an enhancement to the Nine MilePoint Emergency Plan. The EALs have been revised consistent with the NUMARCNESP-007 methodology, and were developed as part of a joint project withall nuclear utilities withinNew YorkState. In order to assist your review we have included a number of developmental documents in the enclosed EALGeneration Package.
The EALGeneration Package consists of the following:
~Plant-Specific EALGuideline
~EAL Technical Bases
~Fission Product Barrier Evaluation
~Emergency Action Level Matrix
~EALBinning Document
~Validation and Verification Report provides an explanation of the contents of the EALGeneration Package.
These EALs were developed as a joint project with the New YorkPower Authority, Consolidated Edison, Rochester Gas and Electric, and Niagara Mohawk. This process ensures consistent emergency classification between all New YorkState nuclear utilities to the greatest extent possible, limited only by plant design differences. We believe that a coordinated review ofall the New YorkState nuclear utilityEALrevisions 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, MJM/JDJ/bh

ATTACHMENT1 NINE MILEPOINT NUCLEAR STATION UNIT 1 EAL GENERATION PACKAGE CONTENT
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.
in P
The PEG is the NMP1 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 NUMARCmethodology are listed in the references section of the PEG.
B 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 xample EALs, and the number of s 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'etermine ifit properly defines the appropriate threshold for the classification. If a condition or set of conditions was appropriate, a comment reflecting this conclusion was recorded in this document. Ifa condition or set of conditions is determined to be inappropriate, it is lined out and the reason for this conclusion is similarly recorded.
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.
NMP1EALTe hnical Ba e D curn n 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 NMP1 EALs and provide historical documentation for future reference.
This document is also intended to be used by those individuals responsible for implementation of the NMP1 classification procedure as a technical reference and aid in EAL interpretation.
NMP1 Emer en Action Level Matrix The Emergency Action Level Matrix is the user level result of the EAL development project.
This matrix willbe incorporated in the Emergency Plan Implementing Procedures and is used directly by operations personnel to classify an event.
I'nR The NMP1 Verification and Validation Report documents the process conducted to verify and to validate'he 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 NMP1 EALs and classification procedures are technically correct.
The NMP1 EAL verification was conducted prior to the EAL validation exercises.
The technical accuracy of the upgraded EALs were verified through tabletop reviews.
, ~
t The validation process ensures that the NMP1 EALs and clarification 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.
