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...

Development of remote alpha contamination measurement detector for field application

TEPCO’s Fukushima Daiichi Nuclear Power Station Accident caused severe accident to lose functions of many instrumentation systems. As a result, many important plant parameters couldn’t be monitored. In order to monitor plant parameters in the case of severe accident, new instrumentation systems available in the severe conditions are being developed. Water level in reactor pressure vessel and hydrogen concentration in primary containment vessel are one of the most important parameters. Performance test ...
