I PURPOSE This procedure provides instructions for establishing special radiation exposure controls during an emergency.

2 REFERENCES 2.1 Title 10, Code of Federal Regulations, Part 20, (10 CFR 20) "Standards for Protection Against Radiation" 2.2 RBNP-024, River Bend Station Radiation Protection Program 2.3 Company Procedure RP-101, Prenatal Exposure 2.4 NCRP Report No. 55, Protection of the Thyroid Gland in the Event of Releases of Radioiodine 3 DEFINITIONS 3.1 Committed Dose Equivalent (CDE) - The dose equivalent to organs or tissues of reference that will be received from an intake of radioactive material during the 50 year period following the intake.

3.2 Total Effective Dose Equivalent (TEDE) - The sum of the Deep Dose Equivalent (DDE) (from external exposure) and the Committed Effective Dose Equivalent (CEDE) (from internal exposure).

4 RESPONSIBILITIES 4.1 Emergency Director (ED)- The ED is responsible for authorizing individuals to receive exposures in excess of 10 CFR 20 limits and approving the issuance of potassium iodide (KI).

4.2 Radiation Protection Coordinator (RPC) - The RPC is responsible for advising the ED, tracking the dose history for those individuals authorized to receive exposures in excess of 10 CFR 20 limits, and notifying the Nuclear Regulatory Commission of any overexposures.

EIP-2-012 REV -16 PAGE 2 OF 14 EIP-2-012 REV - 16 PAGE 2 OF 14

4.3 Senior Radiation Protection Technician (SRPT) - The SRPT is responsible for performing the duties of the RPC per this procedure until his arrival at the Technical Support Center.

5 GENERAL 5.1 During a classified emergency, the administrative exposure controls of the River Bend Station Radiation Protection Program RBNP-024 and RPP-0122, Personnel Monitoring, are suspended; however, efforts shall be made to maintain personnel exposures within the limits established by 10 CFR 20.

5.2 Due to rapidly changing conditions during an emergency, administrative approvals for exceeding established exposure limits are suspended. Only the ED shall have the authority for authorizing exposures in excess of 10 CFR 20 limits (included as Attachment 1 for reference).

5.3 During the emergency phase of an accident, the Radiation Work Permit (RWP) provisions of the River Bend Radiation Protection Program are suspended, but shall be re-implemented at the termination of an emergency when the recovery phase is initiated.

5.4 -Potassium Iodide (KI) (thyroid blocking agent) is available in the Control Room, Technical Support Center, Decontamination Room (Second Floor of the Services Building), Emergency Operations Facility (EOF) and the Offsite Monitoring Team Emergency Kits.

5.5 A declared pregnant female shall not be assigned any functions during a declared emergency which may cause her to exceed the dose limits of 10CFR20.1208 (See Attachment 1); however, a female who declares herself pregnant after an emergency is declared will be expected to continue to fulfill her assignment until a qualified relief can be found. In this case every effort will be made to limit the female's TEDE to the limits specified in Attachment 1, consistent with the needs of the Emergency Response Organization.

6 PROCEDURE NOTE The actions of this procedure may be completed in any sequence, however, the sequence presented is recommended.

6.1 The ED should:

6.1.1. Use 10CFR20 exposure limits contained in Attachment 1.

These limits apply to all members of the Emergency Response Organization, whether or not every person has completed Radiation Worker Training.

6.1.2. When assigning members of the emergency organization to perform tasks which may result in exposures in excess of the 10 CFR 20 limits (see Attachment 1, Section A):

1. Consult with the RPC to determine the person's current exposure history to verify the amount of exposure the individual may receive without exceeding the 10 CFR 20 limit.
2. Authorize each individual a maximum exposure limit, not to exceed the limits in Attachment 1, Section B.

NOTE The Emergency Directorshall initiatea logfor the documentation of emergency information. The Operations Shift Superintendentshall use the ControlRoom log.

3. Document the authorization of each individual in the ED's log.
4. In accordance with the Entergy Operations Inc. policy concerning exposures to females who may be pregnant, no female who suspects she is pregnant should be assigned any responsibilities during an emergency which could result in exposures in excess of the 10 CFR 20 limits.

6.1.3. Ensure that any individual believed to have received greater than 25 rem (250 mSv) TEDE is promptly relieved from the Emergency Response Organization.

EIP-2-012 REV - 16 PAQ F 4 OF 14 ETP-2-012 REV-16 PAGE 4 OF 14

NOTE SCBA 's and other masks do notpreclude the consideration of the disseminationof K..

6.1.4. Authorize the use of KI, as necessary.

6.2 The RPC should:

6.2.1. Ensure that current exposure margins are readily available for the emergency organization.

6.2.2. When time permits, consult with the ED on the methods available to prevent excessive exposures during the emergency.

NOTE SCBA 's and other masks do not preclude the consideration of the disseminationof K[

6.2.3. Consult with the ED regarding the use of KI by emergency response personnel involved in actions to save a life of another individual, mitigate accident consequences, or prevent major releases of radioactivity to the environment I.A.W. Section 6.4 6.2.4. Inform emergency workers who are authorized emergency exposure in excess of 10 CFR 20 limits regarding the relative risks involved with excessive radiation exposure.

6.2.5. Determine the need to process emergency worker TLDs.

6.2.6. Initiate efforts to obtain a medical evaluation of any individual who receives greater than 25 rem (250 mSv) TEDE, during emergency operations by a physician who is familiar with acute effects of radiation exposure. These individuals shall not be subjected to any further radiation exposure until approved by the Superintendent of Radiation Control and the General Manager of Plant Operations.

EIP-2-012 REV -16 PAGE 5 OF 14 ETP-2-012 REV-16 PAGE 5 OF 14

NOTE The following notification will be made in accordancewith the reportingrequirements of 10 CFR 20.2202 and 20.2203.

6.2.7. As soon as practical during an emergency, make oral reports of radiation overexposures to the Nuclear Regulatory Commission followed by a written report. Written reports should be provided within 30 days as provided by 10 CFR 20.2203 except when the emergency continues for more than 30 days, then the written report shall be provided within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after termination of the emergency.

6.2.8. Ensure that TEDE dose received during an emergency is recorded on each individual's dose history file. All occupational doses, including emergency doses, are required to be included as part of an individual's accumulated dose history and can affect the individual's allowable exposure during the current and subsequent years.

6.2.9. Ensure that declared pregnant females do not exceed the dose limits specified in Attachment 1, and that radiation doses to females, who declare themselves pregnant after the declaration of an emergency, are limited to the extent practical to the limits specified in Attachment 1, consistent with the needs of the Emergency Response Organization.

6.3 The SRPT should:

6.3.1. Assume duties of the RPC per this procedure until position is filled.

6.3.2. Assist in evaluating radiation exposure levels likely to be encountered during emergency operations.

NOTE Completion ofAttachment 3 is not requiredunless a worker's thyroid CDE is expected to be >_25 Rem.

Attachment 2 may be used as a reference without completion ofAttachment 3.

6.4 Administration of Iodine Blocking Agents.

6.4.1. Assessing the Need to Issue KI

1. If there is a potential need to issue KI, potential recipients of KI may fill out their portion of Attachment 3 in advance.
2. If a worker's thyroid CDE is expected to approach 25 Rem, obtain a copy of Attachment 2, Thyroid Committed Dose Equivalent Graph, and estimate the dose commitment for the thryoid.
3. Verify your calculations/measurements/estimates and record the results on Attachment 3, Potassium Iodide Administration Form.
4. Report the results to the ED and advise him as to the need to issue KI in accordance with this procedure.
5. The Emergency Director may approve the issuance of KI via telecon/radio.

6.4.2. KI Issuance Requirements

1. When thyroid CDE is estimated to be 25 rem or greater the following are required:

"* The ED shall designate the individuals who will receive KI.

"* The individual to receive KI shall voluntarily elect to take KI.

" The individual to receive KI shall read Potassium Iodide precaution information provided by the drug company. The individual shall then complete the appropriate sections of Attachment 3 - Potassium Iodide Administration Form.

'3. Ensure personnel read and/or complete the appropriate sections of the above.

EIP-2-012 REV - 16 PAGE 8 OF 14 ETP-2-O1 2 REV- 16 PAGE 8 OF 14

6.4.4. Guidelines for the Administration of KI NOTE The Emergency Directorcan authorize the administration of K1 in the field after the FieldMonitoring Team members have complied with the guidelines of this procedure.

Completion of the K1(documentation may be accomplished at the convenience of the Emergency Director.

1. If possible, KI should be administered approximately one half hour before exposure for maximum blockage.
2. Final uptake is halved if KI is administered within 3-4 hours after exposure.
3. Little benefit is gained with KI administration 10-12 hours after exposure.
4. Once the KI is taken and the Iodine concentration is verified or the calculated dose determined, the tablets should be issued for a minimum of six (6) to a maximum of ten (10) consecutive days. One tablet is issued each day.
5. Verify that each individual receiving KI has completed and signed Attachment 3.
6. Verify that there are no "YES" blocks marked for allergies or iodine sensitivity on Attachment 3, Potassium Iodide Administration Form.
7. Individuals who have answered "YES" for allergies or iodine sensitivity to those questions on Attachment 3,,

will initially be considered to be iodine sensitive and must be treated as follows:

1. The individuals will be relocated or replaced to eliminate or minimize the uptake of radioiodine in the thyroid gland, or
2. The individuals WILL NOT receive KI without the Radiation Protection Coordinator's authorization (after evaluation of the "YES" answer and the Emergency Director's concurrence).

EIP-2-012 REV - 16 PAGE 9 OF 14 EIP-2-012 REV- 16 PAGE 9 OF 14

8. Issue each individual designated to receive KI one (1) 130 mg KI tablet.
9. Forward all completed paperwork to the Radiation Protection Coordinator.

6.4.5. Final Conditions

1. Ensure that each individual whose estimated exposure to radioiodine exceeded 25 rem has been identified and administered KI, as appropriate.
2. Ensure all necessary forms are completed and reviewed by the Radiation Protection Coordinator and the Emergency Director.
3. Ensure that each individual who was exposed to radioiodine with a calculated thyroid CDE >25 Rem has been scheduled for bioassay analysis.

7 DOCUMENTATION 7.1 Attachment 3 of this procedure, completed during actual events shall be submitted to permanent plant files (PPF) per EPP-2-100. Attachments from exercises/drills and tests will be used to critique and evaluate exercises/drills and test performance. This documentation will not be sent to PPF and may be discarded.

ATTACHMENT I PAGE 1 OF I RADIATION EXPOSURE LIMITS AND GUIDELINES A. 10CFR20 RADIATION EXPOSURE LIMITS 5 rem/yr. (50 mSv/yr.) Total Effective Dose Equivalent (TEDE) to the whole body.

50 rem/yr. (500 mSv/yr.) sum of the Deep Dose Equivalent (DDE) and the Committed Dose Equivalent (CDE) to an individual organ or tissue other than the lens of the eye.

15 rem/yr. (150 mSv/yr.) Eye Dose Equivalent (LDE) to the eye.

50 rem/yr. (500 mSv/yr.) Shallow Dose Equivalent (SDE) to the skin or an extremity.

50 mrem (0.5 mSv) in a one month period for a declared pregnant female, not to exceed 500 mrem (5 mSv) for the entire 9 month pregnancy period (10CFR20.1208).

B. GUIDELINES FOR EMERGENCY EXPOSURES

1. Emergency Total Effective Dose Equivalent (TEDE) limits are:
a. 5 rem (50 mSv) for preplanned emergency actions.
b. 5 rem (50 mSv), in addition to any other dose received, for Post Accident Sampling.
c. 10 rem (100 mSv) for immediate actions taken to prevent major damage to equipment, prevent the release of radioactive materials, or control fires.
d. 25 rem (250 mSv) without consent and 75 rem (750 mSv) on a voluntary basis for action to save a life or to protect large populations.
2. Committed Dose Equivalent to the Thyroid NOTE Although RBS Emergency Plan Table 13.3-10 establishes thy'oid exposure guidelines, the difficulty in monitoringthyroid exposure over a short period of time prevents use of these numbers as absolute limits.

Therefore, when radioiodineairborneconcentrationsare known, projected thyroid doses will be calculatedto prevent exceeding these guidelines.

a. To save the life of another individual there is no specified limit. Although respirators should be used where effective to control the dose to emergency workers, thyroid dose should not be a limiting factor for lifesaving missions.
b. To mitigate accident consequences and prevent major releases of radioactivity to the environment or control fires- 100 rem (1 Sv) Committed Dose Equivalent (CDE).
c. Emergency duties including decontamination and first aid, but not related to protecting equipment, the public or for lifesaving - 50 rem (500 mSv) CDE.
3. Shallow Dose Equivalent to the Extremities
a. To save the life of another individual, extremity exposure should not be a factor.
b. To mitigate accident consequences and prevent major release of radioactivity to the environment - 100 rem (1 Sv) Shallow Dose Equivalent (SDE).
c. When preplanned emergency actions are possible -50 rem (500 mSv) SDE.

"ATTACHMENT2 PAGE 1 OF 2 THYROID COMMITTED DOSE EQUIVALENT GRAPH Instructions for Use:

1. Determine the estimated or actual 1-131 airborne concentration in the area(s) of interest. Divide this by the protection factor of the equipment used (if unknown, use 1). Locate this number on the Horizontal Axis.
2. Locate the duration of exposure in minutes on the Vertical Axis. Find the point at which this value intersects with the number from step 1.
3. If this point of intersection is located to the left (below) the line, the thyroid CDE is less than 25 rem.
4. If this point of intersection is located to the right (above) the line, the thyroid CDE is greater than 25 rem.
5. If this point of intersection is located on the line, the thyroid CDE is 25 rem.
