Alpha Camera has been developed to check the alpha contamination of solid wastes generated during decommissioning of Fukushima Daiichi Nuclear Power Station (1F). A lot of measurements are needed to reveal the alpha contamination distributions due to the narrow field of view of the Alpha Camera. Therefore, in this paper, we propose a novel approach which reconstructs the divided measurement data in a three-dimensional space to identify the contaminated area easily. In primitive demonstration using new recon...

Alpha Camera is developed as a remotely-operated detector to check the alpha contamination of wastes generated during decommissioning of Fukushima Daiichi Nuclear Power Station. The smear method is currently used to check the alpha contamination inside the plant. However, a large amount of waste will be generated from future decommissioning. Therefore, in order to reduce the exposure of workers, a remotely-operated alpha detector with wide range is needed. In this paper, to confirm that the Alpha Camera can...

Water environment improvement (ex. Hydrogen Water Chemistry (HWC)) is carried out for Stress Corrosion Cracking (SCC) mitigation in some of BWR plants. Japan Nuclear Technology Institute (JANTI) has the guideline on the inspection programs based on effectiveness of environmental SCC mitigation technique for BWR core internals. The guideline provides the crack growth rate (CGR) under HWC. Although CGR is defined by ECP (electroch emical corrosion potential), a dealing of evaluation of ECP and the HWC avail...
