H. Faulkner, Research Agreements Coordinator, Office of International Programs FROM:
B. Grimes, Assistant Director for Engineering and Projects,D0R
SUBJECT:
INFORMATION REQUESTED BY SWISS Enclosed are several documents requested by D. H. Njo during our meeting with the Swiss delegation on November 7,1978. The request was for infor-mation regarding occupational exposures at aperating nuclear power plants.
Our response has been delayed pending completion of some items requested by Dr. Njo. A list of the enclosed information is also attached. Please forward the attached information to Dr. Njo.
In the November meeting, the Swiss delegation briefly described their regu-latory policy on implementation of the As Low As Reasonably Achievable (ALARA) concept to occupational radiation exposures. Their approach appears to be based on cumulative man-rem exposure limits per reactor which is quite different from our approach which has historically avoided the use of speci-fic limits or objectives for total cumulative radiation exposure. The Com-mission, in tneir action on SECY 78-415, asked the staff fo further consider the use of cumulative exposure limits and objectives for implementing ALARA at all licensed facilities including operating power reactors. Consequently, it would be useful to obtain information on the Swiss ALARA regulatory poli-cies. Specifically, the following information would be u'seful:
(1)
Description of the Swiss method 01 implementation of the ALARA occupational exposure concept.
(2)
Description of how cumulative man-rem limits and objectives are determined, especially for power reactors.
(3)
How special reactor maintenance operations, e.g., PWR steam generator repairs and BWR vessel nozzle repairs, are addressed in the establishment of limits or objectives.
(4)
What happens if a licensee, e.g., power reactor, exceeds the limit or objective.
Please forward the above questions to the Swiss with the attached information.
