- 2. 50.14 DERGDCY RADIATION EXPOSURE CONTROL i
1.0 DISCUSSION
During a plant mergency, high levels of radiation and/or radioactivity may be encomtered. These levels may range fra slightly above those experienced during nonnal plant operation to several hundred Rem in a short period of time. Under all situations, whether it is inmediate actions to regain control of the energency or for li'e-saving purposes, care should be taken to minimize personnel exposures fra external and/or internal sources of radiation.
Specific exposure guidelines for entry or re-entry into areas in order to reove injured persons, and/or mdertake corrective actions, are defined in Table I.
The Plant Manager or his designatee will authorize emergency dose guidelines consistent with these or more restrictive dependent upon emergency conditions. The senior Medical Team Representative and the senior Health Physics Representative present should discuss the hazards involved in rescue procedures with the members of the response team prior to undertaking any rescue mission.
O consideretions to de mede v=1or to el1o ins versonnel to eccept ris*s associated with rescue operations will include:
1.
Female sployees of child-bearing age should not be allowed to participate; 2.
Volunteers above the age of 45 years should be given priority; 3.
The individual (s) awareness of the consequences that such an exposure can have; and 4
All practicable protective measures to limit exposure.
Every attempt will be made to maintain exposure to individuals providing other energency fmetions within 10CFR20 regulatory limits and "es low as reasonably achievable." Overall emergency exposure limits, however, are as specified in Table I.
R The Radiological Controls Supervisor, or a designated alternate, is responsible for developing emergency radiological protection progres for f
plant staff and support persomel. Energency kits are provided with high range self-reading dosimeters. Fach individual reporting to the site will be
~
provided a TLD badge. Ibse records will be maintained based upon the results of the self-reading dosimeters. 1his information will be cross-referenced with TLD badge data.
O Guideline action levels for continuous habitability of all emergency centers is presental in Table II.

4.0 PRECAUTIONS
1.
During my emergency involving radiological hazards, exposure to pV personnel should be minimized consistent with the nature of the emergency response required.
2.
Utilize radiological protective measures md equipnent whenever practical.
3.
Acininister potassiun iodide (KI) to all Rescue, Assistance, Site bomdary and Off-Site rame prior to potential iodine exposure, if practicable.
5.0 PROO DJRE-
[
5.1 Fersonnel Search and/or Rescue l
A.
Inmediate Life-Saving Rescue Required l.
Within the limits allowed by the urgency of the situation, make every reasonable effort to assemble as much of the following as can be brought to bear:
a.
pertinent information (i.e., what happened, what may happen, what hazards are present, what cm be done, etc.).
i b.
available protective and nonitoring equipnent and possible rescue devices.
c.
backup assistance from others nearby or request assistance from the Control Roczn.
O l
2.
Evaluate available information ad discuss rescue approach with senior l
l Medical and Health Physics personnel prior to attempt, if practicable.

O 3.
If availal.le, other personnel in the area should render assistance, keep the 'lechnical Support Center advised md monitor the time i
rescuer (r,) are f'. a high radiatim area.
4.
Perfonn rescue mission consistent with good first aid practices md as dictated by dose rates encomtered and the guidelines discussed above.
NOIE:
Work as quickly as is consistent with safety and avoid sources of high dose rates within the rescue area, whenever practicable.
B.
Organized Search and Rescue - following a personnel accountability check 1.
Uoon notification of missing persomel, the Technical Support Coordimtor will page on the Femco to determine if missing personnel may be unharmed, but isolated in see area of the plant or plant site.
2.
If personnel are unaccounted for, the Technical Support Coordinator requests assistance from the Operations Support Center or the Energency Coordinator.
3.
If practicable, the Pescue Team quickly assembles any additional protective equipnent or survey meters which may be needed at the H.P.
Control Point.
O 4.
Concurrently with 3 above, a member of the Rescue Team scans the Radiation ' Work Permits posted on the RWP board in an effort to learn the possible location of missing personnel.
5.
Conduct a search, keeping all members of the rescue tean in the same general area (i.e., frequent visual checks), but each searching independently.
6.
Een victim or victims are located, notify the Technical Support Center intnediately. 'Ihis should be followed up with additional relevant information (i.e., nature and extent of injuries, dose rates encomtered, etc.) as this information develops.
7.
Limit exposure of rescuers to appropriate level specified in Table I.
8.
Treat victims in accordance with 2.50.8, Medical Energency Plan.
6.0 DfERGENCY ON-SI'IE ASSISTANCE i

If prceticable, the Plant Assistance Team proceeds to the H.P.
Control Point and quickly aserrbles any additional protective equipment or survey meters that may be needed depending on the circanstances.
3.
The Plant Assistance Team proceeds to the specified area.
4.
If practical, evaluate conditions and nre-plan activities prior to entry into the incident or work area.
5.
Work as quickly as is consistent with safety and avoid high dose rates whenever practicable.
6.
Perform only those assigned duties intended to control the emergency, but as dictated by the dose rates encomtered and the appropriate emerg y exposure limits specified in Table I.
7.
Report progress and/or ccznpletion of the assigned work to the Technical Support Coordinator by radio or Fenco.
7.0 PEPENNE DOSIMEIRY RECmD-KEEPING R
IUTE:
For the Unusual Event and Alert Conditions, dosimetry issue and records keeping will be done by normal plant procedures.
Q For the Site-Area and General 1:mergencies, dosimetry issue and record keeping will be done at the Energency Operations Facility tnless radiological conditions require issuance at another location.
A.
In-plant Bnergency Centers R
1.
The Health Physics representative will insure that:
a.
Habitability action guidelines specified in Table II are observed, unless otherwise directed by plant management, and b.
All assigned personnel at the Energency Center are wearing their TLD badge and pocket dosimeter.
2.
All persomel assigned duties in a high radiation area, or in the vicinity of the incident, have been issued a high range dosimeter prior to leaving their assigned Bnergency Center.
R 3.
All persomel are responsible for periodically reading their f
dosimeter and noting their level of exposure. Notify the Health Physics representative if dosimeter level approaches full scale.
R 4.
Upon being relieved, each person shall report to the Bnergency h
Operations Facility where his dosimeter reading will be recorded.
R 5.
Dosfinetry records will be maintained at the EOF for all emergency center persomel. Persomel assigned to In-Plant Energency Centers will pick up and return their dosimetry to the EOF at the end of their shift.
