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

a. A radiation monitoring device that continuously indicates the radiation dose rate in the area.

l

b. A radiation monitoring device that continuously integrates the radiation  !

dose rate in the area and alarms when a preset integrated dose is received. j Entry into such areas with this monitoring device may be made after the  !

dose rates in the area have been determined and personnel have been made l knowledgeable of them. ,

l

c. An individual qualified in radiation protection procedures (e.g., a radiation l protection technician or supervisor) with a radiation dose rate monitoring device. This individual shall be responsible for providing positive radiation protection control over the activities within the area and shall perform l

periodic radiation surveillance at the frequency specified by radiation protection supervision.

5.7.2 In addition to the requirements of Specificatica 5.7.1, high radiation areas in which an individual could receive a deep dose equivalent 21000 mrem in one hour (at 30 cm) shall be provided with locked or continuously guarded doors to prevent unauthorized entry. The keys to such locked doors shall be administratively controlled by the shift supervisor or radiation protection supervisor (or respective designee). Doors shall remain locked except during periods of access by personnel under an approved RWP or equivalent.

Individual high radiation areas in which an individual could receive a deep dose equivalent 21000 mrem in one hour (at 30 cm), accessible to personnel, that are located within large areas such as reactor containment, where no enclosure exists for enabling locking, or that is not continuously guarded, and where no lockable enclosure can be reasonably constructed around the individual area, shall be barricaded and conspicuously posted, and a flashing light shall be activated as a warning device..

. /Afjg R'f" ( Conbh stGd) 5.7.3 In addition to requirements of Specification 5.7.1 and 5.7.2 for high radiation areas, if an individual could receive a deep dose equivalent > 3000 mrem in one hour (at 30 cm), the RWP or equivalent shall also specify the maximum allowable stay time or dose (on an alarming dosimeter) for individuals ia those areas. In lieu of the stay time or dose specification of the RWP or equivalent, direct or remote (such as closed circuit TV cameras) continuous surveillance may be made by personnel qualified in radiation protection procedures to provide positive exposure control over the activities being performed within the area.

5.7.4 Individuals qualified in radiation protection procedures or personnel continuously escorted by such individuals may, for the performance of their assigned duties in high radiation areas in which an individual could receive a deep dose equivalent s; 3000 mrem in one hour (at 30 cm), be exempt from the requirements of Specifications 5.7.1 and 5.7.2 for issuance of an RWP or equivalent provided they are otherwise following plant radiation protection procedures for entry into such high radiation areas.
