(a) Do so only on a voluntary basis.
"(b) Be more than 45 years of age.
(c) Be made fully aware of the risks involved, including the numerical levels of dose at which acute effects of radiation exposure will be incurred and numerical estimates of the risks of delayed effects.
EP-IP-440 Rev. 7 Page 7 of 21
6.3 EMERGENCY EXPOSURE DOCUMENTATION ký/; [111 Emergency exposure documentation for ERO personnel shall be maintained by the Onsite and Offsite Radiological Supervisors (as applicable). individual exposures will be recorded on Attachment 1 or other similar form to ensure adequate documentation and tracking during the course of the emergency.
[2] Activities in support of emergency efforts which involve emergency exposure must include a radiological briefing and will be documented through a Radiation Work Permit (RWP) or on an Emergency Radiological Controls Form (Attachment 2).
I NOTE Although it is preferable to document radiological controls prior to dispatching individuals on emergency related tasks, radiological controls and precautions may, be provided verbally and documented as soon as possible thereafter.
[3] Radiological controls determined to be necessary for a task conducted during the emergency are documented on Attachment 2 as follows:
(a) Task Assiqnment: The task, number, location, and date are copied from the OSC Team Task Assignment Sheet or completed as appropriate (for tasks such as RMT dispatch).
NOTE Prior ED/EPM approval must be given for all emergency exposures anticipated to cause an individual to have accumulated greater than 5 rem over the course 6f the emergency.
(b) Task Exposure (Individual) Estimate: The maximum expected dose to any single member of the team. Team members are instructed to either contact the team coordinator or to return prior to exceeding this dose. Consideration shall be given to the benefit of performing the task versus the exposure to be received by personnel when this value has been determined. I (c) Task Dose Rate Limit: The maximum expected whole body dose rate. Team members are to fall back to an area of lower dose rate and contact the team coordinator or return when this limit is encountered.
(d) Dosimetry: Describes any requirements beyond a TLD and SID. A TLD and SID are automatic requirements for all tasks involving radiological controls.
(e) PCs and Respiratory Protection: Denotes the necessary protective clothing and equipment required for the task.
EP-IP-440 Rev. 7 Page 8 of 21
N (f) Sugqgested Route: Best or preferred route to the task site or the sequence to follow for tasks conducted at multiple locations.
(g) Anticipated Conditions: Radiation, contamination, and airborne conditions.
Values need not be provided for tasks which could be hindered by stopping to conduct contamination and airborne surveys. When air sampling is required, ensure guidance is provided regarding:
(1) Sample location(s).
(2) Sample volume (collection time and flow rate).
(3) Analysis or counting method to be used.
(4) Actions for high exposure rates on collected samples.
(h) Survey Equipment and Maps: Describes any radiological equipment and logs or maps used to conduct surveys performed as part of or during the task.
(i) Special Instructions: Describes any additional radiological information or instructions necessary to the task.
[4] Task Exposure: The task exposure section is used to identify the individuals assigned to and track exposure received during conduct of the task. Current emergency dose will be checked against the task exposure estimate prior to teamldispatch to ensure no exposure limits are exceeded without proper authorization.
NOTE Although it is preferable to document authorization prior to tasks which allow extended exposure, authorization may be granted verbally and documented as soon as possible thereafter.
[5] Extended Exposure: The extended exposure section provides authorization by the Emergency Director (or Emergency Plant Manager for onsite ERO personnel when delegated) prior to activities which would result in doses greater than the lower emergency limits.
(a) If the task exposure estimate exceeds 5 rem or the task exposure will result in an individual's emergency exposure exceeding 5 rem, an extended limit must be determined and authorized.
(b) Extended emergency exposures for life saving or protection of large populations anticipated to exceed 25 rem must include additional briefing and documentation in accordance with the Emergency Volunteer Acknowledgment Form (Attachment 3).

[1] EPA-400 specifies that emergency exposures received during an emergency are considered a once-in-a-lifetime exposure and are not added to occupational exposure accumulated under nonemergency conditions.
[2] 10CFR20 specifies doses received during emergencies must be subtracted from the limits for Planned Special Exposures that the individual may receive during the current year and during the individual's lifetime.
[3] Individuals receiving doses beyond the lower exposure limits'shall be restricted from further occupational (nonemergency) radiation exposure pending the outcome of exposure evaluations and medical surveillance.
[4] The Entergy Medical Department shall be contacted for follow-up care and further evaluation, as required.
6.5 ADMINISTRATION OF POTASSIUM IODIDE (KI)
[1] The Emergency Director or the Emergency Plant Manager shall be responsible for authorizing the administration of KI to PNPS emergency workers.
NOTE KI is 90% effective in blocking the uptake of radioiodine by the thyroid if administered within the first hour of uptake, and is 50% effective if administered within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> after uptake.
Almost no benefit will be obtained if KI is administered 10 to 14 hours1.62037e-4 days <br />0.00389 hours <br />2.314815e-5 weeks <br />5.327e-6 months <br /> after exposure; therefore, it shall not be administered after such a duration.
[2] KI should be considered as a potential dose reducing option for any situation in which airborne radioactive iodine is present (an additional ALARA option).
[3] Dose Determination: KI should be administered to emergency workers if by calculation, measurement, or estimation the total dose to the thyroid will exceed i
50 rem.
(a) The isotopic halogen concentrations must be determin!ed before a thyroid dose can be estimated. Concentrations can be determined by direct measurement of each isotope or by estimations based on a known 1-131 concentration.
(1) Concentration estimations can be determined as follows:
- By the use of the Halogen Concentration Worksheet (Attachment 4).
0 Through the use of the Excel spreadsheet file SAMPLE. SAMPLE is loaded on the TSC core damage compute'r and the EOF dose assessment computers.
EP-IP-440 Rev. 7 Page 10 of 21
(2) When estimated concentrations are used, the estimations should be confirmed by direct measurement as soon as practical.
(3) The sample data and calculation sections are used to determine 1-131 activity if an Nal equipped E-600 (or equivalent) is used to analyze the 1-131 concentration. Otherwise, the 1-131 concentration can be entered directly.
(4) Accident type is determined by the Reactor or Core Damage Engineer in the TSC. If the accident type is unknown, assume a gap release.
(b) Thyroid dose can be estimated from isotopic concentrations (in tCi/cc) as follows:
(1) Direct Calculation Thyroid Dose, = Concentration,x DCFP x- x e"-j. t +
DCF (rem

Total thyroid dose is the sum of the individual doses from each of the isotopes above.
(2) Through the use of the Excel spreadsheet file titled SAMPLE. SAMPLE is loaded on the TSC core damage computer and the EOF dose assessment computers.
(3) Through the use of the dose assessment computer application titled DAPAR. DAPAR is loaded on computers in the Control Room and the EOF.

[4] Issuing KI: The Onsite Radiological Supervisor or the Offsite Radiological Supervisor, as applicable, shall:
NOTE The Emergency Director or the Emergency Plant Manager is responsible for authorizing the administration of KI to PNPS emeraencv workers.
(a) Ensure approval and documentation are recorded on the Potassium Iodide Administration Form (Attachment 5).
wo aveknwnCAUTION Indviual Individuals who have known allergies to iodide shall NOT be issued KI.
(b) Notify those who are to receive KI to report to a designated location for distribution.
(c) Issue one 130 mg KI tablet to each individual who is to receive KI. KI is stored in the OSC Medical locker and in the EOF Medical locker. Additional supplies are also located in the Medical Department.
(d) Contact the Entergy Medical Department and request follow-up care and further guidance concerning KI administration.
(e) Instruct individuals to take one 130 mg KI tablet daily for 10 days or as directed by the Entergy Medical Department and record each issuance on the Potassium Iodide Administration Form (Attachment 5).

THE FOOD AND DRUG ADMINISf FRATION APPROVED PACKAGE INSERT HOW POTASSIUM IODIDE WORKS THYRO-BLOCK Certain forms of iodine help your thyroid gland work right.
TABLETS Most people get the iodine they need from foods, like iodized salt or fish The thyroid can "store" or hold only a certain (POTASSIUM IODIDE TABLETS, USP) amount of iodine. i (pronounced poe-TASS-e-um EYE-oh-dyed)
(abbreviated: KI) In a radiation emergency, radioactive iodine may be released in the air. This material may be breathed or swallowed It may enter the thyroid gland and damage it. The damage would probably not show itself for years. Children are most likely to TAKE POTASSIUM IODIDE ONLY WHEN PUBLIC have thyroid damage HEALTH OFFICIALS TELL YOU. IN A RADIATION EMERGENCY, RADIOACTIVE IODINE COULD BE If you take potassium iodide, it will fill up your thyroid gland RELEASED INTO THE AIR. POTASSIUM IODIDE (A This reduces the chance' that harmful radioactive iodine will enter the thyroid gland i FORM OF IODINE) CAN HELP PROTECT YOU.
