EXEMPTION 1.
The North Atlantic Energy Service Corporation (NAESCO) is tbn holder of Facility Operating License No. NPF-86, which authorizes operation of the Seabrook Station, Unit No.1 reactor at a steady-state power level not in excess of 3411 megawatts thermal. The facility is a pressurized water reactor located at the licensee's site in Rockingham County, New Hampshire. This license provide, among other things, that the facility is subject to all rules, regulations, and orders of the Commission now or hereafter in effect.
II.
Section VI(4)(d) of Appendix E to 10 CFR 50, states that "Each licensee shall complete implementation of the ERDS (Emergency Response Data System] by February 13, 1993, or before initial escalation to full power, whichever comes l
later."
By letter dated October 28, 1991, the Seabrook licensee requested a schedular exemption tvom the requirements of Section VI(4)(d) of Appendix E.
The licensee stated that they planned a replacement of the Seabrook Station, Unit I computer system during the third refueling outage scheduled to begin March, 1994.

. III.
In developing the ERDS rule, the NRC staff provided implementation guidance in NUREG-1394, Revision 1.
Appendix J (Question 3) indicates that a cost of $20K to $50K was envisioned for plants where no new hardware was required.
The licensee has indicated that if the exemption is not granted, it l
would be required to install two differeat ERDS for the same reactor within one year at an additional cost (above that estimated in NUREG-1394) of as much as $50K.
In addition, software resources (staff) would have to be diverted from the main plant computer changeout to a redundant ERDS installation.
This would represent redundant and unnecessary cost. The licensee stated it will install ERDS at the same time it is completing installation of the new main plant computer, and, therefore, will comply with the intent of the regulation.
As indicated in NUREG-1394, R; 'sion 1, Appendix J, the NRC response role in an emergency will not materially change due to the ERDS. The ERDS is for NRC information only. Alse, the ERDS does not change the licensee's emergency procedures or response plan.
For these reasons, we conclude that granting a schedular exemption-from Appendix E,Section VI(4)(d) of 10 CFR 50 will relieve the licensee from unnecessary hardship and redundant costs of installing and testing two ERDS systems within one year, costs significantly in excess of those contemplated when the rule was adopted. Therefore, the licensee's request is granted.
4 IV, L
Accordingly, the Commission has de'; ermined that, pursuant to 10 CFR 50.12(a)(1), this exemption is authorized by law, will not present an undue risk to the public health and safety, and is consistent with the common defense and security. The Commission further determines that special circumstances, as provided in 10 CFR 50.12(a)(2)(iii), are present justifying the exemption.
Accordingly, the Commission hereby grants an exemption as described in Section III above from Appendix E,Section VI(d)(4) of 10 CFR Part 50 to extend the completion date of the ERDS.
Pursuant to 10 CFR 51.32, the Commission has determined that the granting of the Exemption will have no significant impact on the environment (57 FR 47126).
This Exemption is effective upon issuance.
FOR THE NUCLEAR REGULATORY COMMISSION original signed by Steven A. Varga, Director Division of Reactor Projects - I/II Office of Nuclear Reactor Regulation Dated at Rockville, Maryland, this 19th day of November 1992.
