Southern California Edison (SCE), licensee for SONGS Unit 1, plans to release the formercooling system intake and discharge piping from the NRC license under provisions of 10 CFR50.83 "Release of part of a power reactor facility or site for unrestricted use" prior to approval ofa license termination plan. This piping is located off-shore from the plant, approximately seven and a half meters (~25') below the surface of the pacific ocean, and about one and a third meters (~4') below the top of the seabed. SCE presented it plans to survey this piping to demonstrate compliance with release criteria (Attachment B). DISCUSSION:

The piping is classified as Class 3 in MARSSIM terminology - affected area not expected tohave residual contamination above a fraction of the DCGL

w. SCE presented it plans to samplethe 30 meters (100') closest to shore of the intake piping and the last 30 meters (100') of the discharge piping because that is where residual contamination is most likely to be. The samples will comprise sediment, sea life, if present, and cores of the concrete pipes. Asufficient quantity of each sample will be taken to split with NRC, and other regulatory agenciesif desired. NRC staff suggested SCE compare actual uptake in sea life, especially crustaceans, with calculated values. Sampling is expected to begin about mid-September, 2006. After sample analyses demonstrate the pipes meet unrestricted release criteria, the western-most (off-shore) 2 meters

(~6') of each pipe will be plugged with concrete. ACTIONS:

SCE will provide an updated schedule, including the submittal date of the request for partial siterelease, once sampling starts. ATTACHMENTS:A: Attendance log B: SCE Presentation
