.s UNIT NO. 1 EMERGENCY PLAN IMPLEMENTING PROCEDURE NO. 1004.9 RADIOLOGICAL CONTROLS DURING EMERGENCIES l
1.0 PURPOSE The purpose of this procedure is to proiride guidelines for coordination of the implementation of the radiological program during emergency conditions and for re-entry operations during and after the declaration of a radiological emergency to assure maximum protection of the general l
l public, plant personnel, and emergency teams without restricting necessary operations and maintenance.
The Radiological Controls Coordinator is responsible for implementing Section 4.0 of this procedure. The Radiological Assessment Coordinator is responsible for implementing Attachment I of this procedure.

Revision 2 3.1.2 If it is necessary to enter an area, during or after a radiation related emergency, in which the radiological conditions are unknown but are suspected to be hazardous.
3.1.3 As referenced by other emergency procedures.
3.1.4 As directed by the Emergency Director.
4.0 EMERGENCY ACTIONS INITIALS NOTE:
For overall coordination of Radiological Controls activities, refer to the Radiological Controls Checklist, Attachment I.
4.1 If exposures in excess of the limits of 10CFR20.101 are anticipated, ensure t' hat each member of the team (Search and Rescuc, Emergency Repair, In-Plant Monitoring, etc.) under-stands that this exposure is voluntary. Exposure in excess of the limits of 10CRF20.101 shall be authorized by the Emergency Director only.
4.2 Preference should be given to those team members who are current in their Radiation Worker Training.
4.3 When re-entry to a hazardous or potentially hazardous area is necessary, ensure that re-entry team members are briefed on all known hazards in the re-entry area (i.e., heat, smoke, steam, flooding, fire, toxic materials, direct radiation and airborne radioactivity levels) and that they are properly prepared.
If time pennits, the re-entry should be planned in detail and every effort should be made to minimize exposure.

team (s) is (are) briefed and ready to perfonn the assigned task.
4.6 Ensure that communications at predetennined intervals, are maintained with the Operations Support Center.
4.7 Appropriate Radiological Controls Procedures (RCP-1602, RCP-1609, RCP-1605) shall be used.
Implement the following i
,(
guidelines and controls when deviations from routine proce-dures are detennined to be necessary. The specifics of the implementation will be dependent on the radiological condi tions. Assign individuals to be responsible for each desig-(
v' nated area and make appropriate entries on Attachment IV.
l 4.7.1 Access Control Insure that inadvertent entry into areas of extreme dose rate does not occur by considering implementa-l tion of one or more of the following controls:
a.
Request the Ops Support Center Coordinator to l
have the Control Room make an announcement over the public address systein identifying the locations of those areas that are off limits due to radiological hazards.
b.
Lock the doors at all possible entry points.

Whole Body"Coun'.s on personnel should be used to evaluate the effectiveness of the respiratory program and the need for additional concern of personnel who have made entries. Unless real-time monitoring is available, air samples should not be used as guidance in determining respiratory require-ments during accident conditions. flaximum protec-l tion shall be afforded each individual.
4.7.5 Personnel Briefing / Debriefing Insure that each individual entering an area of extreme radiation exposure rate has appropriate authorization to enter. A briefing and debriefing
(
should be accomplished before and after each entry.
\\
Attachment I provides guidance in briefing /
debriefing information requirements. The Radio-logical Controls Coordinator should assign a specif_
ic individual (s) to conduct the briefing / debriefing.
NOTE:
These individuals may be located at the access control point and also provide positive access control required by 4.7.1.

Revision 2 4.7.6 Personnel Assignments As soon as possible, individuals should be assigned to maintain radiological controls supplies and equipment. Segregation of contaminated materials for eventual decontamination or discarding should occur. Attachment IV provides specific logistic 3
concerns which should be addressed.
4.7.7 Personnel Decontamination Assign a specific Sdividual to insure all con-taminated personnel are properly deconned and evaluated as necessary. Control Point personnel must be aware of the location of decontaminated facilities and insure contaminated personnel are directed to the facility.
(See procedure 1004.16 Radiation Overexposure and Decontamination, for personnel decontamination).
4.7.8 Bioassay All personnel entering known high airborne radio-activity areas shall be scheduled for whole body count.i. An individual shall be assigned, as soon as practical, to coordinate the whole body counts, assuring that all scheduled personnel are counted, j
reviewing and evaluating the results and. scheduling follow-up counts. Health Physics Consultants (i.e.,
Porter Consultants, Inc., Radiation Management Corporation, etc.) can be used for this function.
