Given the following plant conditions:

. It is the end of a shift and there is an outstanding Configuration Control Card (CCC) that is being maintained in the Control Room

. The component being tracked on the CCC can NOT be returned to its AS FOUND position before the end of shift In accordance with SOMP 02-01 (Safety Tagging and Configuration Control), which ONE (1) of the foIloMng describes the required disposition of the CCC?

A. Document the CCC as part of yourturnover at shift relief.

B. Return the CCC to the OSM. An R&R will be issued prior to shift turnover.

C. Return the CCC to the CRS to determine whether it should be turned over, or if a procedure change will be required.

D. Return the CCC to the WCC SRO. The CCC will be tracked as open until the component can be repositioned to its AS FOUND position.

A radiation worker is repainng a valve in a contaminated area, which has the following radiological characteristics:

. The workers present exposure is I 938 MREM for the year

. The RWP states:

0 General area dose rate = 30 MREM/hr 0 Airborne contamination concentration = I 0. 0 DAC The job will take 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> if the worker wears a full-face respirator. The 2-hour time for work with a respirator includes the respirator-induced inefficiency factor. It will only take I hour if the worker does not wear the respirator.

lfthe RP Manager grants all applicable dose extensions, which ONE (1) of the following choices for completing this job would maintain the workers exposure within the station administrative requirements and the principles of ALARA AND why is that action appropnate?

A. The worker must wear the respirator.

He will exceed DAC limits if he does NOT wear one.

B. The worker must wear the respirator.

The calculated TEDE dose received will be less than if he does NOT wear one.

C. The worker should NOT wear the respirator.

The calculated TEDE dose received will be less than if he does wear one.

D. The worker should NOT wear the respirator.

The dose received wearing a respirator will exceed site annual personnel dose limits.
