Abstract

Radiochemical procedures were developed for the analysis of plutonium in primary cooling water and in ion-exchange resin. Analyses of cooling-water samples from unit 2 of the Ringhals nuclear power station demonstrated that a major fraction of the plutonium found in the cooling water is associated with panicles. The amounts of plutonium isotopes retained annually in the ion-exchange cleaning system are estimated at 3 MBq of ²³⁸Pu and 2 MBq of ^239+240Pu and in a mechanical filter the amounts are estimated at 2 MBq of ²³⁸Pu and 0.6 MBq of ^239+240Pu.
