Raymond F. Fraley Executive Director Advisory Committee on Reactor Safeguards MEthORANDUM FOR:
Mr. William J. Dircks Executive Director for Operations 8

Subject:
OCCUPATIONAL EXPOSURES AT PALO VERDE NUCLEAR GENERATING STATION AND OTHER SYSTEM 80 PLANTS During its review of the CESSAR-80/Palo Verde Nuclear Generating Station, Units 1, 2, and 3, the ACRS was provided estimates of the'annual collec-tive occupational dose associated with the operation of each unit at the Palo Verde Station which may average well over one-thousand person rem.
In view of the fact that these units are based on a standard design which supposedly incorporates application of the ALARA principle, the members expected somewhat lower dose estimates.
In this connection, it should be noted that the occupational dose esti-mates may have been unduly conservative and therefore misleading.
The Committee's review did not provide an opportunity to examine the basis for these dose estimates in detail and this should be done to determine if they result from the CESSAR-80 design, the balance of plant design, the proposed method of operation, or other factors.
The Committee urges attention to this matter regar ding the Palo Verde Station and. the CESSAR-80 standardized plant design.
The ACRS Subcom-mittee on Reactor Radiological Effects would be pleased to discuss this matter further with the NRC Staff.
