5.0 ADMINISTRATIVE CONTROLS
K. 5.7 High Radiation Area
5.7.1 Pursuant tol10 CFR 20. paragraph 20.1601(c), in lieu of the
requirements of 10 CFR 20.1601, each high radiation area, as.
defined in 10 CFR 20, in which the intensity of radiation is
> 100 mrem/hr but < 1000 mrem/hr, shall be barricaded and
conspicuously posted as a high radiation area and entrance thereto
shall be controlled by requiring issuance of a Radiation Work
Permit (RWP). Individuals qualified in radiation protection
procedures (e.g.. Radiation Protection personnel) or personnel
continuously escorted by such individuals may be exempt from the
RWP issuance requirement during the performance of their assigned
duties in high radiation areas with exposure rates 5 1000 mrem/hr,
provided they are otherwise following plant radiation protection
procedures for entry into such high radiation areas.
Any individual or group of individuals 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.
b. A radiation monitoring device that continuously integrates
the radiation dose rate 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 rate
levels in the area have been established and personnel have
been made knowledgeable of them.
c. An individual qualified in radiation protection procedures
with a radiation dose rate monitoring device, who is
responsible for providing positive control over the
activities within the area and shall perform periodic
radiation surveillance at the frequency specified by the
Radiation Protection Supervisor in the RWP.

High Radiation Area

5.7 High Radiation Area (continued)
5.7.2 In addition to the requirements of Specification 5.7.1. areas
accessible to individuals with radiation levels such that an
individual could receive in 1 hour a dose equivalent > 1000 mrems
but < 500 rads at one meter from sources of radioactivity shall be
provided with locked doors to prevent unauthorized entry, and the
keys shall be maintained under the administrative control of the
Nuclear Shift Supervisor on duty and/or the radiation protection
supervision. Doors shall remain locked except during periods of
access by personnel under an approved RWP that shall specify the
dose rate levels in the immediate work areas and the maximum
allowable stay times for individuals in those areas. In lieu of
the stay time specification of the RWP, 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.
5.7.3 For individual areas accessible to individuals with radiation
levels such that a major portion of the individual's body could
receive in 1 hour a dose > 1000 mrems with measurement made at
30 centimeters from the source of radioactivity, but < 500 rads at
one meter from sources of radioactivity that are located within
large areas such as reactor containment, where no enclosure exists
for purposes of locking, and where no enclosure can be reasonably
constructed around the individual area, that individual area shall
be roped off and conspicuously posted, and a flashing light shall
be activated as a warning device.
