Abstract

It is very important to minimize the secondary waste generation for the decontamination of the primary coolant system. The SP-HyBRID process can obtain a similar decontamination performance to the HP CORD UV process. The SP-HyBRID decontamination wastewater can be purified by a precipitation process using Ba(OH)2, and the waste generation can be greatly reduced. For this reason, removal tests of impurities in a SP-HyBRID decontamination wastewater surrogate were conducted using the precipitation process. As the results, the impurities in the surrogate were effectively removed, and the waste generation was reduced by 60% when compared with the HP CORD UV process.
