AREA HIG~ RADIATION 8_D...0~U8 O-S*.~A-13
- Revision-0 May 1975 A.
SYMPTOMS
- 1.
Routine survey indicates high radiation.
- 2.
ARM or MAIN STEAM LINE HIGH* RADIATION. alarm.
- 3.
Removal or re-arrangement of shielding.
- 4.
Removal of source from its shielded container.
B.
AUTOMATIC ACTIONS
- 1.
SBGTS starts and* reactor building ventilation system isolates when radiation levels reach llMR'reactor building ventilation exhaust or lOOMR refueling floor.
C.
IMMEDIATE OPERATOR ACTIONS
- 1.
Verify automatic actions, if radiation levels reach trip points in-dicated in 8.1.
- 2.
Assign personnel to guard entry to the area and prevent access.
Use Public address system to warn personnel of access restrictions.
D.
SUBSEQUENT OPERATOR ACTIONS
\\
- 1.
Locate the source of radiation.
- 2.
Survey to ~eter~ine the limits of the high radiation area and establish a controlled crea.
- 3.
Install temporary shielding~ place the source of radiation in a shielded container, or. reduce reacto~.power as applicable.
- 4.
Follow abncr:-::al procedure for fuel element failure high radiation if applicable (DGA-16).

Notify Radiation-Chemical Supervisor and request assistance in restor-ing area to previous backgro~nd levels.
].
Refer to Dresden Radiation Control Standards and OSEP.
E.
