i Radiological Field Operations Personnel Qualification / Training Program The purpose of this program is to establish qualification standards for Radiological Control technicians and Radiological Control Foreman at Three Mile Island and Radiological Control technicians and Radiological Control Group Supervisors at Oyster Creek. This program includes the minimum theoretical and practical training requirements to ensure that tnose per-sonnel assigned to the Radiological Field Operations Department understand their general and specific radiological duties. The theoretical and practical ability requirements are attached as Appendices A and B respectively.
Contractor personnel are used to fulfill manpower needs during periods of fluctuating radiological workloads. Contractor personnel are required to meet the same training requirements as Company personnel. Contractor personnel may be exempted from the entire training program provided that:
- 1. Their services are performed as defined by the Manager Radiological Field Operations or his designee, and:
- 2. They receive training in procedures applicable to their specific duties.
The training program consists of initial training of selected Radiological Control Technicians and a cyclic training program for all Technicians, Foreman and Group Supervisors. The cyclic training material is based upon but is not limited to:
- 1. Areas where weaknesses in performance have been noted.
- 2. Areas where regulations and/or procedures have changed.
- 3. Areas where increased deptn in academic understanding will improve performance.
- 4. Areas where requalification training requirements exist.
Written qualification and where applicable requalification examinations will be administered for all levels. The written examinations will be used to evaluate an individuals ability to meet objectives following the completion of formal classroom training. Oral Board examinations will also be given as a means of determining their ability to respond to unusual radio-logical situations. The pass / fail criteria used in conjunction with the written and oral examinations are contained in
2 the Station Procedures covering the qualification and training of Radiological Field Operations Personnel.
The Practical Factors portion of the training program is administered through the use of Practical Factors Worksheets which contain materials outlined in Appendix "B" attached.
Each item on the Practical Factors Worksheet shall be completed as an actual task unless approved otherwise by the Manager, Radiological Field Operations or his designee. Radiological Field Operations personnel will be restricted to performing, unsupervised, only those tasks for which the Practical Factors Worksheets have been signed as approved.
Written qualification /requalification examinations.shall be administered and corrected by the Radiological Training Depart-ment. Oral Board examinations shall be administered by manage-ment personnel designated in writing as approved examiners by the Manager, Radiological Controls or the Radiological Controls Director.
The following training records shall be maintained by the Radiological Training Department.
- 1. All final written qualification /requalification exami-nations.
- 2. A summary statement of the individual's performance in oral board examinations, including the areas covered oy the examination.
- 3. All Completed Practical Factors Worksheets.
- 4. A Certificate of Qualification signed by the Manager, Radiological Controls or the Radiological Controls Director.
- 5. Records of qualification of Contractor personnel tempo-rarily cmployed in Radiological Field Operations.
The following training records shall be maintained by the Training Department:
- 1. Certificates of Qualification.
- 2. Summary records of all training delivered by the train-
! ing' department and such other records as provided by the Rad Con Department, along with achievement levels on Radiological Field Operations personnel.
