WASHINGTON, D.C. 20006 0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NOS. 182 AND 186 TO FACILITY OPERATING LICENSE NOS. DPR-24 AND DPR-27 WISCONSIN Ft FCTRIC POWER COMPANY POINT BEACH NUCLEAR PLANT. UNITS 1 AND 2 DOCKET NOS. 50-266 AND 50-301 I
1.0 INTRODUCTION
j By letter dated January 21,1997, as supplemented and modified on December 15,1997, the Wisconsin Electric Power Company (the licensee) requested amendments to the Technical Specifications (TS) appended to Facility Operating Licenses Nos. DPR-24 and DPR-27 for the J
Point Beach Nuclear Plant, Units 1 and 2. The proposed amendments would revise TS Section 15.6.11, " Radiation Protection Program," to update references to 10 CFR Part 20, " Standards for Protection Against Radiation." Section 20.1101, " Radiation Protection Programs," requires licensees to develop and implement a radiation protection program appropriate to the scope of licensed activities and potential hazards._ Section 20.2102 requires licensees to document these programs.
The December 15,1997, supplement provided clarifying information and modified proposed language within the scope of the original application and did not change the staffs initial proposed no significant hazards considerations determination.
2.0 EVALUATION The licensee has proposed a complete revision of TS 15.6.11. The revision specifes what constitutes high radiation areas, specifies posting, barricading, access restrictions, and monitoring required for these areas.
The current TS defines a high radiation area as having an intensity of radiation greater than 100 j
mrom/hr but less than 1000 mrem /hr (with measurements made at no more than 18 inches l
from the source of radioactivity.) The proposed TS address two categories of high radiation l
areas and provide specific requirements for each. The two categories are (1) high radiation j
l areas with dose rates not exceeding 1.0 rem / hour at 30 centimeters from the radiation source or from any surface penetrated by the radiation, and (2) high radiation areas with dose rates greater than 1.0 rem / hour at 30 centimeters from the radiation source or from any surface penetrated by the radiation, but less than 500 rads / hour at 1 meter from the radiation source or from any surface penetrated by the radiation. The categories of radiation areas are consistent with 10 CFR Part 20 requirements and are acceptable to the staff.

' Current TS require each high radiation area to be conspicuously posted and the entrance thereto controlled by requiring issuance of a radiation work permit (RWP). The current TS allow health physics qualified personnel or personnel escorted by health physics personnel to be exempt from the RWP issuance requirement during the performance of their assigned radiation protection and operational surveillance duties, provided they comply with approved radiation protection procedures regarding entry into high radiation areas and radiological conditions l
remain stable.
l l
The proposed TS for "High Radiation Areas with Dose Rates Not Exceeding 1.0 rem / hour at 30 l
Centimeters from the Radiation Source or from Any Surface Penetrated by the Radiation" requires:
- a. Each entryway to such an area shall be barricaded and conspicuously posted as a high radiation area. Such barricades may be opened as necessary to permit entry or exit of personnel or equipment.
- b. Access to, and activities in, each such area shall be controlled by means of Radiation Work Permit (RWP) or equivalent that includes specification of radiation dose rates in the immediate work area (s) and other appropriate
{
radiation protection equipment and measures.
- c. Individuals qualified in radiation protection procedures (e.g., health physics technicians) and personnel continuously escorted by such individuals may be exempted from the requirement for an RWP or equivalent while performing their assigned duties provided that they are following plant radiation protection procedures for entry to, exit from, and work in such area.
The proposed TS for "High Radiation Areas with Dose Rates Greater than 1.0 rem / hour at 30 Centimeters from the Radiation Source or from Any Surface Penetrated by the Radiation, but Less than 500 rads / hour at 1 Meter from the Radiation Source or from Any Surface Penetrated by the Radiation" specifies the following:
- a. Each entryway to such an area shall be conspicuously posted as a high radiation area and shall be provided with a locked door or gate that prevents unauthorized entry, and, in addition:
- 1. All such door and gate keys shall be maintained under the administrative control of the shift supervisor, radiation protection manager, or his or.her designee.
- 2. Doors and gates shall remain locked except during periods of personnel or equipment entry or exit.
I
- b. Access to, and activities in, each such area shall be controlled by means of i
an RWP or equivalent that includes specification of radiation dose rates in
.L 3
the immediate work area (s) and other appropriate radiation protection equipment and measures.
- c. Individuals qualified in radiation protection procedures may be exempted from the requirement for an RWP or equivalent while performing radiation surveys in such areas provided that they are following plant radiation protection procedures for entry to, exit from, and work in such areas.
An additional restriction was added for this high radiation area to specify that "Such individual areas that are within a larger area that is controlled as a high radiation area, where no enclosure exists for the purpose of locking and where no enclosure can reasonably be constructed around the individual area need not be controlled by a locked door or gate, but shall be barricaded and conspicuous, clearly visible flashing light shall be activated at the area as a waming device."
The requirements for posting, barricading, locking, and control of access to high radiation areas are clarified by use of wording suggested for plants converting to improved Standard Technical Specifications as described in an April 9,1997, letter to the Nuclear Energy Institute (NEI) from C.I. Grimes, Chief, Technical Specifications Branch, Office of Nuclear Reactor Regulation. The revised wording is acceptable to the staff.
The current TS requires radiation monitoring for entry into a high radiation area that consists of the following:
- a. A radiation monitoring device which continuously indicates the radiation dose rate in the area.
- b. A radiation monitoring device which continuously integrates the radiation dose rate in the area and alarms when a preset integrated dose is received.
Entry into such area with this monitoring device may be made after the dose rate level in the area has been established and personnel have been made knowledgeable of these conditions.
- c. Coverage by an individual qualified in radiation protection procedures who is equipped with a radiation dose rate monitoring device. This individual shall be responsible for providing positive control over the activities within the area and shall perform periodic radiation surveillance as specified by the plant health physics supervisor on the RWP.
I The proposed TS for radiation monitoring in "High Radiation Areas with Dose Rates Not Exceeding 1.0 rem / hour at 30 Centimeters from the Radiation Source or from Any Surface Penetrated by the Radiation" requires as one attemative for each individual or group entering such an area possession of:
- 4. A self-reading dosimeter (e.g., pocket ionization chamber or electronic dosimeter) and, [such individual or group shall)
d
" (i) Be under the surveillance, as specified in the RWP or equivalent, while in the area, of an individual qualified in radiation protection procedures, equipped with a radiation monitoring device that continuously displays radiation dose rates in the area; who is responsible for controlling personnel exposure within the area, or (ii) Be under the surveillance as specified in the RWP or equivalent, while in the area, by means of closed circuit television, o' personnel qualified in radiation protection procedures, responsible for controlling personnel radiation exposure in the area, and with the means to communicate with and control every individual in the area.
Similar'y, the proposed TS for "High Radiation Areas with Dose Rates Greater than 1.0 rem / hour at 30 Centimeters from the Radiation Source or from Any Surface Penetrated by the Radiation, but Less than 500 rads / hour at 1 Meter from the Radiation Source or from Any Surface Penetrated by the Radiation" requires:
- d. Each individual or group entering such an area shall possess:
- 1. A radiation monitoring device that continuously integrates the radiation rates in the area and alarms when the device's dose alarm setpoint is reached, with an appropriate alarm setpoint, or
- 2. A radiation monitoring device that continuously transmits dose rate and cumulative dose information to a remote receiver monitored by radiation protection personnel responsible for controlling personnel radiation exposure within the area with the means to communicate with and control every individual in the area, or
- 3. A self-reading dosimeter (e.g., pocket ionization chamber or electronic dosimeter) and, (i) Be under the surveillance, as specified in the RWP or equivalent, while in the area, of an individual qualified in radiation protection procedures, equipped with a radiation monitoring device that continuously displays radiation dose rates in the area; who is responsible for controlling personnel exposure within the area, or (ii) Be under the surveillance as specified in the RWP or equivalent, while in the area, by means of closed circuit television, of personnel qualified in radiation protection proce nres, responsible for controlling personnel radiation exposua; in the area, and with the means to communicate with and control every individual in the area, or
1 4. In those cases where options (2) and (3), above, are impractical or determined to be inconsistent with the "As Low As is Reasonably Achievable" principle, a radiation monitoring device that continuously displays radiation dose rate:, in ther area.
The proposed changes are consistent with the guidance provided in the April 9,1997, letter -
from the NRC to NEl and are acceptable to the staff.
