UNITED STATES OF AMERICA NUCLEAR REGULATORY COMMISSION In the Matter of WISCONSIN ELECTRIC
)
POWER COMPANY Docket No. 50-266 (Point Beach Nuclear Plant
)
Unit 1)
)
~
EXEMPTION I.
Wisconsin Electric Power Company (the licensee) is the holder of Facility Operating License No. DPR-24 (the license) which authorizes oper,
ation of the Point Beach Nuclear Plant, Unit No.1 (the facility) at' a steady state reactor power level not in excess'of 1518 megawatts thermal.
The facility consists of a Westinghouse E,lectrtt Corporation designed-pressurized water reactor (PWR) located at the licensee's site in Manitowoc County,, Wisconsin.
The license is subject to all rules, regulations and Orders of the Commission.
II.
10 CFR 50.44(c)(3)(iii) requires a licensee to provide each light-water nuclear power reactor with high point vents for the reactor coolant system, for the reactor vessel head, and for other systems required to maintain adequate core cooling if the accumulation of non-condensible gases would cause the loss of function of these systems.
Required modifications are to be completed by the end of the first scheduled outage of sufficient duration beginning after July 1, 1982.
By letter dated June 18, 1982, the licensee requested an exemption to the schedular requirements of Paragraph (c)(3)(iii) of 10 CFR Part 50.44.
The licensee requests that it be granted an exemption until no later than 8302d20226 830125 PDR ADOCK 05000266 P
2 January 1,1984 to install the reactor coolant system and reactor vessel head high point vents for the Point Beach Nuclear Plant, Unit No.1.
The licensee has stated that the control panels necessary to pennit
. complete remote operation of the reactor cooJant gas vent system for Point Beach Unit No. I were not available for installation during the Fall 1982 annual refueling outage for this unit. The Fall 1982 refueling outage was the first sc,heduled outage of sufficient duration after July 1,1982 to -
permit installation of the reactor coolant gas vent system at Point Beach Unit 1.
The licensee has further stated that the Point Beach Unit No. I reactor coolant gas vent system valves and piping are installed and have been hydrostatically tested. Manual valves upstream of the vent. valves are closed to preclude inadvertent operati,on of system.
The licensee has further stated that temporary-power supplies could be utilized to operate the reactor vessel head vent in the event of an accident occurring before final installation is completed. The existing Power Operated Relief Valves form the pressurizer high point vent portion of the system. These are fully operable.
Delivery of the control panels necessary to permit remote operation of the reactor coolant vents system is expected in the Spring of 198'i. The I
next scheduled outage for Po. int Beach Unit No.1 is the Fall 1983 annual re fueli ng. out. age.
Final hookup and functional system testing will be accomplished during this outage.
The NRC staff has reviewed the basis for an exemption to the RCS vents 1
schedule for, Point Beach Unit No.1.
The licensee's efforts to minimize inadvertent F.tuation by removing power from the power operated solenoid isolation valv-es until construction is completed are warranted. Since the like-lihood that vents would be needed prior to the completion of the vent system is low, the NRC sta.ff concludes that a schedular exemption to the hydrogen rule vents requirements (10 CFR 50.44(c)(3)(iii)) until the system controls are in-l

stalled and fully tested, but no later than January 1, 1984, is reasonable and that the licensee's request for exemption should be granted.
III.
Accordingly, the Commission has determined that, pursuant to 10 CFR 50.12, the exemption requested by the licensee's letter of June 18, 1982, as discussed above, is authorized by law and will not endanger life or property or the common defense and security, and,is otherwise in the public interest. The requested exemption is hereby granted as follows:
The date specified in Paragraph (c)(3)(iii) of 10 CFR Part 50.44 to complete installation of reactor coolant system high point vents is extended to no later than January 1,1984 for the Point Beach Nuclear Plant, Unit No.1.
The Commission has concluded, based on the considerations discussed above, that (1) because the granting of this Exemption does.not involve a significant increase in the probability or consequences of an accident previously evalaated, does not create the possibility of an accident of a type different from any evaluated previously, and does not involve a significant reduction in a margin of safety, the Exemption does not in-volve a significant hazards consideration, (2) there is reasonable as-surance that the health and safety of the public will not be endangered by operation in the proposed manner, and (3) such activities will be con-i ducted in compliance with the Commission's regulations 'and the granting of this Exemption will not be inimical to the common defense and security -
or.to the health and safety of the public.
The Commission has determined that the granting of this Exemption 4.will not result in any significant environmental impact and that pursuant j
...,...... ~..,..
e to CFR 51.5(d)(4) an environmental impact statement or negative declara-tion and environmental impact appraisal nee,d not be prepared in connection with this action.
This Exemption it, effective upon issuance.
