Qualification tests of coatings for inner walls in a BWR reactor

摘要

Qualification tests of coatings for inner walls in a Boiling Water Reactor (BWR) were performed under request for decontamination purposes. Several types of coatings were contaminated with fission products obtained from a UO2,solution irradiated in a nuclear research reactor,afterwards a successive decontamination process according with standards based on gamma activity was applied. In each decontamination stage, alpha and gamma activity measurements were made on the probes. Results obtained for cl activity using nuclear track detectors are presented as an alternative assessment method during the decontamination process. [References: 2]
