3[1 The Honorable Alan Cranston APR 2 4 M United States Senate Washington, DC 20510

Dear Senator Cranston:

I am writing in response to your letter dated March 5,1986 to the NRC Office of Congressional Affairs in which you forwarded concerns by several of your constituents about the Rancho Seco Nuclear Generating Station. Specifically, i

the concerns expressed by your constituents are based on a preliminary proposal by the Sacramento Municipal Utility District (SMUD) to construct radioactive waste evaporation ponds at the Rancho Seco Nuclear Power Station.

The evaporation ponds were being considered by SMUD as a conceptual means of handling some of the relatively low level liquid radioactive waste which is generated at the plant. However, at the present time SMUD is not pursuing the evaporation pond method of handling the icw level liquid radioactive waste.

The radioactive material of interest, resulting from some radioactive leakage through the steam generators, is currently being collected on feedwater demineralizer resins in a process which is very similar to that used in home water purification systems. The contaminated resins are then disposed of at a licensed low level radioactive waste burial facility instead of being regenerated at the Rancho Seco facility.

Should SMUD decide to pursue the evaporation pond alternative in the future, i

a detailed description of the process and an associated safety evaluation would be submitted to the NRC for review. These submittals have not been made and SMUD has informed the NRC that they are not expanding resources on this project at the present time.

I trust this is responsive to your constituent's concerns.

Sincerely,

~ ~ " T.A neta GJ Victor Stello, Jr.

Specifically, the concerns expressed by your constituents are based on a preliminary proposal by the Sacramento Municipal Utility District (SMUD) to construct radioactive waste evaporation ponds at the Rancho Seco Nuclear Power Station.

The evaporation ponds were being considered by SMUD as a conceptual means of i

The evaporation pond alternative, should SMU decide to pursue in the future, a detailed description of the process an'd associated safety evaluation would g

be submitted to the NRC for review. These ubmittals have not been made and SMUD has informed the NRC that they are t

panding resources on this project at the present time. We will keep you dvise if SMUD resurrects the evapor-ation pond alternative.
