The Status of Standardization for Nuclear Fuels Reprocessing Facilities - Design / Construction and Fitness-for-Service of Equipments -

We have both the national technical standards and the japanese society standards, that is, the nuclear power generation facilities codes available for the japanese nuclear power plants in terms of design and fitness-for-service. They are already esta blished, systematized and incorporated in our regulations, so that chey are referred when the design or the inspections take place at the stage of plant construction and when nspections, evaluations and maintenance have to be carried out properly dur ing the o...

The Situation of Standardization about a Design / Fitness-for-Servicefor Nuclear Fuels Reprocessing Facilities

The nuclear fuels reprocessing facilities are required to perform appropriate maintenances for the ageing phenomena of the facilities. Development of non-destructive testing devices with high detection precision of the defects, small sizes, and lightweights are essential for testing the facilities. In this study, thallium bromide (TlBr) detectors, which have high absorption efficiency for gamma rays, are developed for the application to a radiographic testing (RT) device. The detector performance was...
