EXEMPTION 1.

The Virginia Electric and Power Company (VEPC0 the licensee) is the holder of Facility Operating License No. DPR-32 and Facility Operating License No. DPR-37, which authome operation of the Surry Nuclear Power Station.

Units 1 and 2.

The licenses provide that ti.e licensee is subject to all rules, regulations, and orders of the U.S. Nuclear Regulatory Commission (NRC or the Commission) now or hereafter in effect.

The facility consists of two pressurized-water reactors at the licensee's site located in Surry County, Virginia.

II.

The Code of Federal Regulations at 10 CFR 70.24. " Criticality Accident Requirements." requires that each licensee authorized to possess special nuclear material shall maintain a criticality accident monitoring system in each area in which such material is handled, used, or stored.

Sections 70.24 (a)(1) and (a)(2) specify detection and sensitivity requirements that these monitors must meet. Section 70.24(a)(1) also specifies that all areas subject to criticality accident monitoring must be covered by two detectors.

Section 70.24(a)(3) requires licensees to maintain emergency procedures for each area in which this licensed special nuclear material is handled, used, or stored.

. and provides (1) that the procedures ensure that all personnel withdraw to an area of safety upon the sounding of a criticality accident monitor alarm. (2) that the procedures must include drills to familiarize personnel with the evacuation plan, and (3) that the procedures designate responsible individuals for determining the cause of the alarm and placement of radiation survey instruments in accessible locations for use in such an emergency. Section 70.24(b)(1) requires licensees to have a means by which to quickly identify personnel who have received a dose of 10 rads or more.

Section 70.24(b)(2) requires licensees to maintain personnel decontamination facilities, to maintain arrangements for a physician and other medical personnel qualified to handle radiation emergencies, and to maintain arrangements for the transportation of contaminated indNduals to treatment facilities outside the site boundary.

Section 70.24(c) ext ts Part 50 licensees from the requirements of 10 CFR 70.24(c) for tcial nuclear material used or to be used in the reactor. Subsection 70. 4(d) states that any licensee who believes that there is good cause why he should be granted an exemption from all or part of 10 CFR 70.24 may apply to the Commission for such an exemption and shall specify the reasons for the relief requested.

III.

By letter dated January 27, 1997, as supplemented March 24, 1997 VEPC0 requested an exemption from 10 CFR 70.24(a). The Commission has reviewed the licensee's submittal and has determined that inadvertent criticality is not likely to occur in special nuclear materials handling or storage areas at Surry Nuclear Station. Units 1 and 2.

The quantity of special nuclear material other than fuel that is stored on site is small l

enough to preclude achieving a critical mass.

The purpose of-the criticality monitors required by 10 CFR 70.24 is to ensure that if a' criticality were to occur during the handling of special

~

nuclear material, personnel would be alerted to that fact and would take appropriate action. Although the staff has determined that such an accident l

1s not likely to occur, the licensee has radiation monitors, as required by-

' General. Design Criteria 63, in fuel storage and handling areas.

These

-monitorsfwill alert personnel to excessive radiation levels and allow them to l-1 initiate appropriate safety actions 11H3 low probability of an inadvertent criticality together with the licensee's adherence to General Design Criterion 63 constitute good cause for granting an exemption to the. requirements of 10 CFR 70.24(a).

IV.

The Commission has determined-that, pursuant to 10 CFR 70.14..this

-exemption is authorized by: law, will not endanger life or property or the common defense and security, and is.otherwise _in the public interest:

therefore, the Commission hereby grants the following exemption:

The Virginia Electric and Power Company is exempt from the requirements of 10 CFR-70.24(a) for the Surry Nuclear Power Station. Unit 1 and Unit 2.

Pursuant to 10 CFR 51.32, the Commission has determined that the granting of this exemption will have no significant impact on the quality of the human environment ( 62 FR 44495).

'T.';is exemption is effective upon issuance.
