~
Radiation Work Permits 1.0 PURPOSE The purpose of the procedure is to explain the proper method of completing a Radiation Work Permit (R.W.P.).
2.0 DISCUSS,10N A RWP is required of all personnel prior to entering an area posted with signs indicating, CAUTI0ti:
Radioactive Materials, Airborne Contamination, High Radiation Area, Radiation Area, and Contaminated Area. This procedure provides a means of controlling access to areas wher e personnel could receive exposures in excess of the limits in 10CFR20.
Individuals enter.ing RWP areas must have obtained at least RWP clearance or be provided with a qualified escort.
Only in the event that safety of equipment or personnel is endangered, may entry be made into a "RWP Required Area" without a RWP.
In such a case, the entry will be made by qualified oersonnel (HP Clearance) carrying portable radiation monitors, wearing appropriate protective clothing, dosimeters and film badges.
Following such an entry, a permit will be executed shortly thereafter.
Using the RWP as a keypunch form permits pertinent information to be inputted into the REM (Radiation Exposure Monitoring) computer system.
This information will be used to generate reports on Man-Rem Exposure by Job Category and Radiation Work Permit Detail List.
For further information on computer applications of the RWP refer to the Radiation Exposure Monitoring System (REMS) Procedure Manual.

NOTE:
Radiation Protection Personnel may enter an area where limits may or do exceed either/or all of a, b and c for the purpose of conducting a radiological survey for the preparation of an R.W.P. without first having a valid R.W.P.
If this is the case, the person conducting the survey will use the last survey of the area as a guideline for choosing the

~
when required, and to see that all Radiation Controls are enforced while work is in progress.
In addition, it is the responsibility of the personnel involved to adhere to the instructions listed on the R.W.P.
5.2 Initiation of RWPs All RWPs (except standing RWPs) will automatically terminate on the day following the issue date or as specified by the Radiation Protection Supervisor / Foreman.

5.2.2 Blocks #1, #2, #3, #4 and #5 should be filled in by the person initiating the RWP.
NOTE:
Block #3, the Job Ticket Number, composed of component, task, and schedule number, will be used for future cross-reference with the maintenance systems.
If the Job Ticket Number is not available, the Work Request Number may be used. Block #4, the Job Category Code, will be used in the REM system to break down exposure (Man-Rem) by Job Category and 2

Refuelino All jobs related to a scheduled refueling period.
This period will be from plant shutdown for refueling to establishment of normal plant operation.
The person initiating the RWP takes it to the Radiation Protection Department.
5.2.3 The persen initiating the RWP will then take the RWP to the Job Foreman in charge of the work. The Job Fortman will complete the information in block #7, " Author! zed Personnel".
