Ex-post evaluation of safety research by technology interaction analysis

Yanagisawa, Kazuaki; Komoda, Fumio*

By using the database INSPEC, an ex-post evaluation of the safety research was carried out by a technology interaction analysis. Selected institutions were JAERI, ORNL and FZK. As the control term of INSPEC a water-reactor-safety was utilized and studied the established key technologies and the interacted technological elements. (1) For a nuclear safety research JAERI held priority to 22 out of 30 key technologies consisted of the nuclear fuels, the nuclear materials and so on. JAERI contributed much to Japan. For ORNL and FZK, 19 and 20 key technologies were held priorities. ORNL was in the ascendant at the nuclear power plant operation, while FZK held priority to the radiation protection. (2) JAERI and FZK interacted strongly with the accident, the engineering calculation, the fuel cladding and the reactor core cooling. The interaction was enhanced by an international cooperation like LOFT. As for JAERI and ORNL, they interacted strongly with the instruments and the research reactors.
