As part of the on-going EPRI research program to control radiation fields in LWRs, decontamination processes for use on core materials are being qualified. In this project, two BWR fuel assemblies were chemically decontaminated, one each with the AP/CAN-DECON and AP/LOMI processes. Both assemblies had been irradiated for three fuel cycles in the Quad Cities Nuclear Station. The primary objective was to study the effects of commercially available decontamination reagents on fuel assembly materials. A secondary objective was to show that these reagents can effectively remove crud deposits from fuel surfaces. In addition, CERT specimens made from an irradiate dcontrol blade were exposed to the decontamination reagents to look for indications of irradiation assisted SCC or other types of corrosion.
