In our letter of April 15, 1988 (Refe:ence 3) we responded to various questions, which you had posed (Reference 2) in regard to your evaluaticn of revisions to the LACLWR Emergency Plan s.bmitted previously (Reference 1).

One cocnent which had l>een raised by you (Reference 2) wa a m uest for us to provide a technical basis which demonstrates that there 12 3 r ;essity for a Site Area or a General Emergency classification during LACBWY. '.,AFSTOR

Document Control Desk LAC-Page 2 s May 17, 1988 equivalent limits should not be exceeded by onsite personnel, if precautionary sheltering.....out to 80 meters....is undertaken (for a ground'r'elease). This scenario included a ground level release of Kr-85 from damaged spent fuel assemblies with containment not being isolated. Sheltering should be done at the ALERT declaration, if significant fuel damage with potential for a ground level release, is the initiating condition.

In our telephche conversation (Reference 4), you requested that we include a statement regarding precautionary sheltering and Control Room ventilation isolation in the Emergency Plan revision. We have made a change to the Emergency Plan, Section 3.8.1 "Radiological Protection of Onsite Personnel" (page D-12) which describes the conditions for precautionary onsite sheltering and Control Room ventilation isolation. This change is enclosed with this letter for your review.

Please replace the old page D-12 in the copies of the Emergency Plan revision which were sent to you (Reference 3) with this new page D-12.

If you have any questions or comments, please contact us.
