A Study on an improvement of the small sodium leakage detection system (Conceptual study)

not registered 

A study on an improvement of the small sodium leakage detection system of the FBR plant was carried out. At first, the item which should be improved were examined and focused to S/N, responsibility and exclusive detectability for sodium aerosol. Next, the feature of the new detection techniques which could be feasible was studied. Then, the laser breakdown spectroscopy was selected as an advanced system. Finally, development subjects were picked up, and the direction of the research and developmet program was proposed.
