JSee Title Page Georgia Power A .. o 1 of 9 RADIATION EXPOSURE LIMITS A. PURPOSE To provide limits of exposure for the protection of personnel against radiation hazards arising from work associated with the operation of the Hatch Nuclear Plant.

The limits of exposure as set forth in this procedure are based upon applicable limits as described in 10 CFR 20, Standards for Protection Against Radiation. A continuous effort will be made to reduce levels of radiation and radioactivity in order to maintain radiation doses as low as reasonably achievable below these establist ! ad limits.

D. MAXIMUM PERMISSIBLE EXPOSURE (10 CFR 20). (Tech. Spec. Section 6.1 \ L

l. The maximum quarterly' exposure to the whole body, head and trunk, active blood forming organs, lens of the eyes or gonads shall be limited to 3,000 mrem / quarter.

2. The maximum quarterly exposure to the skin of the whole body shall be 1.imited to 7,500 mrem / quarter.

3. The maximum quarterly exposure to the extremities, hands and forearms, feet and ankles, shall be limited to 18,750 mrom/ quarter.

NOTE .

All limits of exposure are bbsed upon individuals 18 years of age and older. No person under 18 years of age shall be occupationally exposed to ionizing radiation. ,

! 4. The limits as set forth above are subject to the following conditions:

a. The dose to the whole body, when added to the accumulated occupational dose, shall not exceed 5(N-18) rem, where "N" equals the , individual's age in years on t

his last birthday.

b. The individual's accumulated occupational dose to the whole body has been determined and recorded on Form 1, Occupational External Radiation Exposure History.

See Title Page 2 of 9

c. No individual will be permitted to receive a whole body exposure in excess of 300 mrem / quarter unless he has submitted a signed statement indicating the amount of occupational exposure received during the current quarter from sources of radiation possessed or controlled by other licensees and a reasonable effort to obtain the individuals prio'r occupational exposure has been made. In the event an individual is unable to provide exposure information for the current quarter, and his duties are likely to result in an exposure in excess of 300 mrem before such information could be obtained, authorization to 2500 mrem may be granted using Form 2 of this procedure, by the Plant Manager and the Health Physics Superintendent provided: (1) a current quarter exposure of 1250 mrem is assumed, (2) prior quarter exposures are known or have been calculated in accordance with 10 CFR 20.lO2(c)(1), and (3) the Plant Manager has declared the individual critical to start-up or continued operations.

C. MAXIMUM PERMISSIBLE CONCENTRATIONS IN AIR (10 CFR 20)

No individual will be permitted to inhale a quantity of radioactive material in any period of one calendar quarter greater than the quantity which would result from inhalation for 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> per week for 13 weeks at uniform concentrations of radioactive material in air as specified in Appendix B Table I, Column 1. If the radioactive materials are of such form that intake by absorption through the skin'is~11 Rely, individual exposures to radioactive material shall be controlled so that the uptake of radioactive material by any organ from either inhalation or absorption or both routes of intake in any calendar quarter does not exceed that which would result f,com inhaling such radioactive material for 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> per week for 13 weeks at

uniform concentrations specified in Appendix B Table 1, Column 1 .

of 10 CFR 20. Refer to 10 CFR 20. 103 for further details.

D. ADMINISTRATIVE EXPOSURE GUIDES

1. Administrative exposure guides are established to provide l guidelines for plant operations in order that personnel I exposures will be maintained within the maximum limits as l established in 10 CFR 20 and Section B of this procedure.

I 2. Exposure of the whole. body shall be limited to 300 i mrem / week. This administrative limit, however does not relieve the individual or his supervisor from their responsibliity to keep all radiation exposure as low as

, reasonably achievable (ALARA).

See Title Page 3 of 9

3. Whole body radiation exposure,above.3OO mrom in any week will require written approval from the immediate supervisor and a Lab Foreman on Form 2, Authori~zation to Exceed Administrative Exposure Guides. '

4. Exposure of the whole body shall be, limited to 1,250 mrem / quarter.

5. Whole body radiation exposure above 1,250 mrem / quarter will require written approval from the immediate supervisor and a Lab Foreman on Form 2, Authorization to Exceed Administratiave Exposure Guides. In no case, except for conditions as specified in Section C, shall a whole body exposure exceed 2500 mrem / quarter as measured by pocket dosimeter,or estimated by portable Health Physics instruments,

6. All female employees working in the Protected Area will be required to acknowledge in writing that she has received s ~

instruction concerning prenatal radiation exposure on Form 4.

For purposes of administering a program for limiting exposure to pregnant women, the following administrative guides will be established:

Radiation exposure to female employees wil.1 be limited to 500 mrem per two month period unless a higher limit is specifically requested in writing by the employee on Form 4.

Radiation exposure to pregnant women will be limited to 500 mrem during the entire gestation period unless a higher limit is specifically requested in writing by the employee on Form 4. -

E. ADMINISTRATIVE CCNTROL OF INTERNAL EXPOSURE

1. Exposure to airborne concentrations approaching the MPC's of 10 CFR 20 should be prevented. If exposure above the MPC's are necessary, the wear.ng of properly fitted respiratory protective equipment or other appropriate methods will be required as determined by the Health Physics staff.

HNP-80lO specifies administrative controls for use of respiratory equipment. .

2. Plant personnel normally traversing Radiation Control Areas should have a whole body count annually.

F. EXPOGURE LIMITS FOR NON-PLANT PERSONNEL

1. .

Vendors, subcontractors, and other non plant personnel who are likely to receive a whole body radiation exposure in excess of 300 mrem in any calendar quarter shall be required ,

to furnish current radiation exposure records.

2. The quarterly exposure to the whole body shall be limited to 1,250 mrem. Any occupational exposure received at another facility during the current quarter -(whether. actual, based

. on TLD or film badge results, or estimated, based on pocket dosimeter results, or a combination thereof) shall be considered in the maintenance of this limit. However, if mutual agreement between Georgia Power Company and the pertinent outside organization exists, and provided that the requirements of 10 CFR 20, Section 20.101 have been satisfied, this limit may be exceeded. Refer to Form 2, Authorization to Exceed Radiation Exposure Guides.

Subcontractor personnel must have received the Radiation Protection Orientation lectures or demonstrate knowledge covered in the lectures, and must agree to abide by the regulations and policies of the Georiga Power Company prior to gaining access without escort to areas where radiation exposures may be received.

G. EMERGENCY AND ACCIDENTAL EXPOSURE Although an emergency situation transcends the normal requirements of limiting exposure, there are suggested levels for exposure. Refer to HNP-4812 for guidance.

H. ADNORMAL PERSONNEL EXPOSURES Whenever a situation occurs involving the suspected or known exposure of personnel to ionizing radiation in excess of 10 CFR 20 limits specified in this procedure, the incident will be promptly investigated and personnel exposures evaluated.

Personnel monitoring results that are either excessively high or excessively low with respect to the work that an individual has been known to be doing, will also be immediately investigated.

All such incidents will be immediately reported to the H.P. .

Laboratory Foreman or his alternate. A committee consisting of the Laboratory Foreman, Health Physics Superintendent or his i designee, and supervisor of the group in which the abnormal exposure occurred, will conduct an official investigation and issue a written report of its findings and recommendations to the concerned individual, his immediate supervisor and the Plant Manager. Every effort will be made to determine if the suspected exposure is actual exposure using, as necessary, special bio-assays, whole body counting, radiation surveys, and reviews of work assignments and working procedures.

1 i

The written report submitted will consist of the investigation, the evaluation of results documented on Form 3, Abnormal Radiation Exposure, and a Radiation Occurrence Report (Figure 2 FNPJSOOS).
