Fuel Safety Research Meeting 2005, which was organized by the Japan Atomic Energy Agency was held on March 2-3, 2005 at Toshi Center Hotel, Tokyo. The purposes of the meeting are to present and discuss the results of experiments and analyses on reactor fuel safety and to exchange views and experiences among the participants. The technical topics of the meeting covered the status of fuel safety research activities, fuel behavior under Reactivity Initiated Accident (RIA) and Loss of coolant accident (LOCA) conditions, high fuel behavior, and radionuclide release under severe accident conditions. This summary contains all the abstracts and sheets of viewgraph presented in the meeting.

True-stress vs. true-strain analysis with results of ring tensile tests

Hamanishi, Eizo*

JAEA introduces analytical method to obtain true stress - true strain curve from the ring tensile test results. In the method, Finite Element method Analysis is performed iteratively to reproduce the experimental load - displacement curve. The strain hardening exponent and the strength coefficient, representing the true stress - true strain obtained by this analysis, were in agreement with reference data. Accordingly, the evaluation method was successfully verified.
