MILLSTONE NUCLEAR POWER STATION. UNITS 1. 2. AND 3 DOCKET NOS. 50-245. 50-336. AND 50-423

1.0 INTRODUCTION

By letter dated December 30,1997, the Northeast Nuclear Energy Company (the licensee) submitted Revision 24 to the Millstone Nuclear Power Station (MNPS) Emergency Plan (the Plan) for the NRC's review and approval. In the letter, the licensee stated that the revision was in accordance with 10 CFR 50.54(q) and did not decrease the effectiveness of the Plan, and, as revised it continued to meet the standards of 10 CFR 50.47(b) and the requirements of Appendix E to 10 CFR Part 50. However, the licensee requested NRC review and approval of Revision 24 to resolve concems raised over the licensee's emergency plans as documented in NRC Inspection Report Numbers 50-245/97-81,50-336/97-81, and 50-423/97-81.

By letters dated March 24, April 15, and May 13,1998, the licensee submitted Change 1, Change 2, and revised Change 2, respectfully, to the Plan. These changes were updates to Revision 24 submitted on December 30,1997.

2.0 BACKGROUND

The licensee implemented Revision 22 of the Plan in June 1997. Revision 22 was issued as a complete revision of the Plan. In August 1997, the licensee implemented Revision 23 of the Plan to correct problems the licensee had subsequently identified in Revision 22.

During an inspection conducted in August 1997, as documented in NRC Inspection Report Numbers 50 245/97-81,50 336/97-81, and 50-423/97-81, the inspectors reviewed selected portions of Revisions 22 and 23 of the Plan. The inspectors concluded that, with the implementation of Revision 22, the licensee made changes to the Plan, which decreased its effectiveness. The changes were made without Commission approval, in some instances, the MNPS Emergency Plan, as changeci, no longer continued to meet some of the standards of 10 CFR 50.47(b), and some of the requirements of Appendix E to 10 CFR Part 50. The inspectors identified several items that were omitted from Revisions 22 and 23. The licensee stated that 1 Revision 24 provided enhancements to the Plan, and requested NRC's review and approval of the Plan. '

The staff evaluated Revision 24 of the Plan against the standards of 10 CFR 50.47(b) and the

. requirements of Appendix E to 10 CFR Part 50 using the guidance provided by NUREG-0654,

. " Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants," Revision 1, dated November 1980, and the guidance contained in NUMARC/NESP-007, " Methodology for Development of Emergency Action 9906000344 980604 5 PDR ADOCK 0

2 Levels," Revision 2, dated January 1992. The staff also considered in the review process the information contained in NUREG-1031, Supplement No. 4, " Safety Evaluation Report Related to the Operation of Millstone Nuclear Power Station, Unit No. 3," dated November 1985.
