Development of sampling and assay methods for WAGR radwaste
The radioactive waste inventories for the Windscale advanced gas-cooled reactor (WAGR) have been assessed and demonstrated. Methods for assay and codes to calculate the inventory of weak emitters, following measurement of dominant gamma emissions, have been developed. This report covers: - methods for cost-effective sampling of steel and for assay of cobalt, nickel, niobium, silver and europium therein; - investigations into activities in WAGR graphite; - preliminary work on activities in WAGR concrete; - development of calculation codes for the estimation of radwaste total activity, given a measure of the dominant gamma radiation emissions from Co-60, applicable especially to steel radwaste. The study showed that adequate sampling and assay methods for characterising steel radwaste can be defined, and that provision can be made for these during WAGR dismantling.
