ST LUCIE NUCLEAR PLANT INITIAL LICENSE EXAMINATION ADMINISTRATIVE JPM A-4 ST. LUCIE RADIATION REQUIREMENTS Directions to the applicant for Administrative JPMs:

I will explain the initial conditions and state the task to be performed. You will be allowed to use any reference need to complete the task. Ensure you indicate to me when you finish your assigned task by returning the material needed for the task that I provided you.

Initial Conditions:

Unit 1 is in a refueling outage. During the Upper Guide Structure (UGS) lift, it was identified that three (3) CEAs have become caught on the UGS and were being withdrawn. The UGS was set back down in the reactor vessel and a recovery plan was developed.

The recovery plan will take 40 minutes to complete (not including setup and cleanup) in a 2900 mR/hr field. It has been decided that this does NOT constitute a Planned Special Exposure (PSP). All four workers current years exposures are documented and up to date.

Worker 1 must enter the work area 5 minutes prior to the rest of the group to set up the equipment. He will leave at the end of the recovery plan.

Worker 2 will enter the work area after Worker 1 has setup the equipment. He will remain in the work area for the entire recovery plan and will spend 10 additional minutes cleaning up.

Worker 3 will enter the work area after the equipment is set up and will remain for the entire recovery plan.

Worker 4 will enter the work area after the equipment is set up and will leave 10 minutes into the recovery plan.

Below are the workers dose records:

Initiating Cue:

1. What dose would be received for each person?
2. Which worker(s) is(are) allowed to perform the recovery plan in accordance with approved FPL procedures?
3. What highest level of managerial approval is required for each worker in accordance with approved FPL procedures?

  • Worker 1 exceeds the 1 R limit annual site dose, so at least the PGM approval is required. He does not exceed the 2.5 R (site) or 3 R (all sites) dose, so no higher approval is required.
  • Worker 2 exceeds the NRC limit of 5 R for the year. This is not an emergency or PSE so no extension is available.
  • Worker 3 exceeds the 2.5 R site dose, this requires VP approval.
  • Worker 4 does not exceed the 1R site dose or 3 R all-site dose. No further approvals are required.
