. *6. 3 (Cont'd)

A. High Radiation Area In lh u of the " control device" or " alarm signal" required by paragraph 20.203(c)(2) of 10 CFR Part 20, each high radiation area in which the dose rate is greater than 100 mrem /hr but less than 1000 mrem /hr* shall be barricaded (barricade will impede physical movement across the entrance or access to the high radiation area; i.e., doors, yellow and magenta rope, turnstile) and conspicuously posted as a high radiation area and entrance thereto shall be controlled by requiring issuance of a Special Work Permit (SWP)**.

Any individual or group of individuals permitted to enter such areas shall be provided with or accompanied by one or more of the following:

1. A monitoring device which continuously indicates the radiation dose rate in the area.

2. A monitoring device which continuously integrates the radiation dose in the area and alarms when a preset integrated dose is received. Entry into such areas with this monitoring device

.! may be made after the dose rates in the area have been

! established and personnel have been made knowledgeable of them.

3. A radiation protection qualified individual (i.e., qualified in radiation protection procedures), with a dose rate monitoring device, who is responsible for providing positive control over

the activities within the area and shall perform periodic dose i- rate monitoring at the frequency specified by Health Physics

) supervision.

I In addition to the requirements of the above specification, areas accessible to personnel with dose rates such that a major portion of the body could receive in I hour a dose greater than 1000 mrem

• shall be provided with locked doors to prevent unauthorized entry.

Doors shall remain locked except during periods of access by personnel under an approved SWP which chall specify the dose rates in the immediate work area. For individual high radiation areas accessible to personnel that are located within large areas, such as the containment, or areas where no enclosure exists for purposes of locking and no enclosure can be reasonably constructed around the individual areas, then that area shall be barricaded and conspicuously posted. Area radiation monitors that have been set to alarm if radiation levels increase, provide both a visual and an audible signal to alert personnel in the area of the increase.

These monitors may be used to meet specifiention 6.3.A.1 provided that the dose rates and alarms have been established by radiation protection personnel. Stay times or continuous surveillance, direct or remote (such as use of closed circuit TV cameras), may be made by personnel qualified in radiation protection procedures to provide additional positive exposure control over the activities within the area.

• Measurement made at 18 inches from source of radiation. l

• • Radiation protection personnel or personnel escorted by radiation protection personnel shall be exempt from the SWP issuance requirement during the performance of their assigned duties, provided they are otherwise following plant radiation protection procedures for entry into high radiation areas.
