4.3 Fully Qualified Radiation Protection Technician (FQRPT) - The FQRPT 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 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 proceduremay be completed in any sequence, however, the sequencepresented 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 Control Room 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.

EEP-2-012 REV - 15 PAGE 44 OF 16 Efl'-2-O12 REV 15 - PAGE OF 16

NOTE SCBA 's and other masks do not preclude the consideration of the disseminationof KI 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. After the emergency is terminated, 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.

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

Completion of the KI 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 Attachments 3 and 4.

6. Verify that there are no "YES" blocks checked on Attachment 4, Medical Questionnaire: Iodine Sensitivity.

7. Individuals who have answered "YES" to any question on Attachment 4, Medical Questionnaire: Iodine Sensitivity, 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).

8. Issue each individual designated to receive KI one (1) 130 mg KI tablet.

17.1P-*-Ol 2 REV - 15 PAGE 9 OF 16 1FYP-2-01 2 REV - 15 AE9F1

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 Attachments 3 and 4 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.

ATFACHMENT 1 PAGE 1 OF 2 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 thyroid exposure guidelines, the difficulty in monitoring thyroid exposure over a shortperiod 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.

EIP-2-012 REV - 15 PAGE 11 OF 16 ELP-2-012 REV-IS PAGE11OF16

ATTACIIMENT 1 PAGE 2 OF 2 RADIATION EXPOSURE LIMITS AND GUIDELINES 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.

ATTACHMENT 2 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.t of intersection is located on the line, the thyroid CDE is 25 rem.
