ADDITIONAL RESPONSES TO AGENCY COMMENTS WASHINGTON NUCLEAR PROJECT, UNITS 1 AhT 2 Docket Nos, 50-460/513 Federal Energy Administration l

Coastent:

"It is unclear from the description of the gaseous waste management system (Gm!S) in Section 3 that sufficient I

amounts of krypton-85 will be stripped from the gaseous waste and placed in controlled containers.

If not, the alternative of installing cryogenic noble gas strippers and facilities to compress and bottle krypton-85 should be discussed."

Response

The term " stripping", as used in the DES, refers to the process of separating dissolved gases from the primary coolant liquid and does not infer the stripping of the isotope krypton-85 from the gaseous waste. The alternative of installing cryogenic noble gas strippers and facilities to compress and bottle krypton-85 was not considered in the DES beca'use the proposed radwaste systems meet our ALAP criteria and are therefore acceptable.
