RP-AA-203 Revision 3 Page 2 of 12

3.1. Responsibility

for approval of exposures in excess of administrative dose control levels resides with the Radiation Prot ection Manager (RPM), the Station/Plant Manager, and the Site Vice President.

4. MAIN BODY 4.1. Limitations

4.1.1. Exposures

shall not exceed the 10CFR20 Exposure Limits as described in Table 1, "NRC Exposure Limits."

TABLE 1 - NRC EXPOSURE LIMITS Individual and Limit Type TEDE LDE SDE TODE (1) Occupational Worker, Minor, Routine Annual 0.5 rem 1.5 rem 5 rem 5 rem (2) Occupational Worker, Adult, Routine Annual 5 rem 15 rem 50 rem 50 rem (3) Occupational Worker, Adult, PSE Annual 5 rem 15 rem 50 rem 50 rem (4) Occupational Worker, Adult, PSE Lifetime 25 rem 75 rem 250 rem 250 rem (5) Declared Pregnant Woman Dose equivalent to the embryo/fetus of 500 mrem, or 50 additional mrem if the dose equivalent to the embryo/fetus exceeds 450 mrem at

the time the female declares, in writing, her pregnancy. (Note: The

dose equivalent to the embryo/fetus equals the DDE to the declared

pregnant woman plus the dose equivalent to the embryo/fetus from radionuclides in the embryo/fetus plus the dose equivalent to the embryo/fetus from radionuclides in the declared pregnant woman.)

(6) Member of The Public The total effective dose equivalent to individual members of the public shall not exceed 100 mrem in a year.

RP-AA-203 Revision 3 Page 3 of 12 NOTE: Any request to raise the admin istrative dose control level for a minor shall be approved and documented by the Radiation Protection Manager. 4.1.2. Administrative dose control levels have been established for Total Effective Dose Equivalent Limits as follows:

2000 mrem routine cumulative TEDE/yr.

200 mrem TEDE for minors. NOTE: In the Midwest Regional Operating Group, controls for High Lifetime Exposure are not applicable for non-Exelon employees due to the limitations of the Exposure Tracking System. 4.1.3. An administrative dose control level of 1000 mrem TEDE plus PSE has been established for employees with High Lifetime Exposure. 4.1.4. The Radiation Protecti on Manger shall review an individual's occupational exposure when the dose equivalent reaches 80% of the NRC Limits for Lens Dose Equivalent (LDE), Shallow Dose Equivalent (SDE), and Total Organ Dose Equivalent (TODE).

The 80% threshold values are as follows:

12 rem LDE.

40 rem SDE.

40 rem TODE.

4.1.5. If an individual's current year dose hi story documentation includes an absent/

no record (A) dose type, then REDUCE the individual's allowable exposure (normally 2000 mrem TEDE for the year) by 1250 mrem TEDE for each quarter of the current year for which dose history documentation is absent/

no record (A), until all of that dose is resolved.

4.1.6. If an individual is suspected of exceeding any of the NRC exposure limits in Table 1, then PROHIBIT the individual from entering the RCA until a detailed evaluation of the individual's actual dose equivalent has been conducted. Future access will depend

upon the results of the evaluation.

1. If an exposure in excess of the applic able exposure limit has occurred, then PROHIBIT the individual from entering the RCA until the end of the current calendar year. 2. If an exposure in excess of the applicable exposure limit has not occurred, then the individual may be permitted to re-enter the RCA.

RP-AA-203 Revision 3 Page 4 of 12

The Radiation Protection Department s hall complete Section II Attachment 1 or computerized equivalent. 4.2.4. Pending investigations or calculati ons of internal exposure shall be reviewed and evaluated to determine the individuals TEDE. 4.2.5. Non-Exelon Nuclear and non-ROG dose equi valent shall be included in the dose to determine the worker's current TEDE. NOTE: An individual shall not be approved to receive greater than 2000 mrem TEDE if that person has any absent/

no record (A) dose equivalent for the year. 4.2.6. T o raise the ADCL up to and including 3000 mrem TEDE in a calendar year, written a pproval is required by the Radiati on Protection Manager and the work group supervisor.

4.2.7. T o raise the ADCL to between 3001 and 4000 mrem TEDE in a calendar year, written a pproval is required by the Radiation Pr otection Manger, a work group supervisor, a nd the Station/Plant Manager. NOTE: An individual being considered for approval greater than 4000 mrem TEDE for the year should not have significant estimated dose equivalent. 4.2.8.

Individual's supervisor, RPM, Plant Manager, and Site Vice President for end of year dose equivalent exceeding 2000 mrem TEDE. 4.4. Planned Special Exposures (PSEs)

NOTE: PSEs are not the same as emergency doses. PSEs only apply to adult workers. 4.4.1. PSEs are to be authorized only in excepti onal situations when alternatives that might avoid the dose estimated to result from the PSE are not available or are deemed impractical. 4.4.2. A manager from the departm ent requesting a PSE shall submit a request to the Radiation Protection Department, indicating:

The name and identification number of each individual for whom a PSE is being requested, and The nature of the task for which a PSE is being requested, and A detailed explanation of why the PSE is necessary. 4.4.3. Prior written approval is required before the PSE occurs.

RP-AA-203 Revision 3 Page 6 of 12

4.4.4. Prior

to participating in a PSE, individuals involved shall be: 1. Informed of the purpose of the PSE.

2. Informed of the estimated dose and associated potential risk or conditions involved in performing the PSE. 3. Instructed in dose reduction measures and techniques for the PSE. 4.4.5. PSE approval is granted when the PSE document is signed (by hand) and dated by:

The individual(s) for whom a PSE is being requested, and The work group manager or other leve l of supervisory authority for the individual as chosen by the RPM or designee, and The RPM or designee, and The Plant Manager, and The Site Vice President.

NOTE: If there are any periods of expos ure during the life of the monitoring individual that have not been determined or documented (i.e., Absent/

No record), then participation in a PSE is not permitted. 4.4.6. All of the individual's previous PSE dos e equivalents and previous doses in excess of routine occupational limits must be deter mined from records for each individual who will participate in the PSE. Doses rece ived in excess of the routine occupational dose limits in effect at the time of exposures during accidents and emergencies must also be determined and subtracted from the limits for PSEs.

4.4.7. DOCUMENT

each individual's current year and previous years:

PSE dose equivalents, and Dose equivalents in excess of the exposure limits in effect at the time of the exposures (rows (1) and (2) of Table 1, "NRC Exposure Limits," and the former 10 CFR 20.101), and Dose equivalents in excess of any non-NRC exposure limits. 4.4.8. The maximum authorized dose equivalent an individual may receive for a PSE shall be limited to an amount that does not cause the individual to receive a dose equivalent in excess of the limits li sted in rows (3) and (4) in Table 1.

4.4.9. DOCUMENT
