1 7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION ERT.H ATLANTIC ENERGY SERVICE CORPORATION. ET AL DOCKET NO. 50-443 NOTICE OF ISSUANCE OF AMEN 0 MENT TO FACILITY OPERATING LICENSE The U. S. Nuclear Regulatory Commission (the Commission) has issued Amendment No. 33 to Facility Operating License No. NPF-86, issued to North Atlantic Energy Service Corporation (the licensee), which revised the Technical Specifications for operation of the Seabrook Station, dit No. 1 (Seabrook) located in Rockingham County, New Hampshirs. The amendment is effective as of the date of its issuance, to be implemented before startup from the fourth refueling outage.
The amendment modifies the Seabrook Technical Specifications (TS) to permit operation of the Seabrook core with an expanded axial flux difference band (wide-band operation) from that currently permitted.
'her TS changes allow for fuel design enhancements. Wide-band operation is based on information derived from the fixed in-core detector system (FIDS).
The core design enhancements are based on methodologies described in Yankee Atomic Electric Company reports YAEC-1849P, YAEC-1854P, and YAEC-1856P which were approved previously for use at Seabrook. Additionally, the licensee supported the proposed technical specification changes with reanalyses of the Updated Final Safety Analysis Report Chapter 15 accidents and transients, documented 9412010226 941123 PDR ADOCK 0500 3

. in YAEC-1871, and a Westinghouse Electric Corporation loss-of-coolant-accident reanalysis. These supporting documents and a revised Core Operating Limits Report were submitted with the application for amendment.
The licensee proposed certain changes to TS 3.1.1.3 that would permit operation with a positive moderator temperature coefficient. The Commission has not yet determined the acceptability of this proposed change pending submission of additional information from the licensee. Therefore, the proposed change to TS 3.1.1.3 is not implemented by this amendment.
This amendment affects TS Sections 3.1.3.4, 3.2.1, 3.2.2, 3.2.3, 3.2.4, 3.2.5, 3.3.3.2, 4.2.1, 4.2.2, 4.2.5, 4.5.2, 5.3, and 6.8.1, Figure 2.1-1, and Tables 2.2-1, 3.3-4, and 4.3-1.
The application for the amendment complies with the standards and requirements of the Atomic Energy Act of 1954, as amended (the Act), and the Commission's rules and regulations.
The Commission has made appropriate findings as required by the Act and the Commission's rules and regulations in 10 CFR Chapter I, which are set forth in the license amende nt.
