NUCLEAR REGULATORY COMMISSION

[Docket No. 50-443]

 

North Atlantic Energy Service Corporation, et al; Notice of 
Issuance of Amendment 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, 
Unit No. 1 (Seabrook) located in Rockingham County, New Hampshire. 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. 
Other 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 
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 
amendment.
    Notice of Consideration of Issuance of Amendment and Opportunity 
for Hearing in connection with this action was published in the Federal 
Register on January 18, 1994 (59 FR 2632). No request for hearing or 
petition for leave to intervene was filed following this notice.
    For further details with respect to this action see (1) the 
application for amendment dated November 23, 1993, as supplemented by 
letter dated August 15, 1994, (2) Amendment No. 33 to License No. NPF-
86, and (3) the Commission's related Safety Evaluation, and (4) the 
Commissions Environmental Assessment dated September 27, 1994. All of 
these items are available for public inspection at the Commission's 
Public Document Room, 2120 L Street, NW., Washington, DC, and at the 
local public document room located at the Exeter Public Library, 47 
Front Street, Exeter, NH 03833.

    Dated at Rockville, Maryland, this 23rd day of November, 1994.

    For the Nuclear Regulatory Commission.
