Japan Atomic Energy Research Institute (JAERI) has been developing design studies of the Gas Turbine High Temperature Reactor (GTHTR300) based on the experiences of development of the High Temperature Engineering Test Reactor (HTTR) of JAERI. Feasibility of the GTHTR300 fuel which is irradiated under high burnup condition of approximately 140GWd/t at the maximum was investigated. It was certified that failure of coated fuel particles during irradiation will not occur and the integrity of coated fuel particles will be kept. Cost evaluation for fuel production and fuel cycle was also studied in order to clarify the economical feasibility which is important item for the development of the GTHTR300. The fuel cost per electricity production is estimated to be less than 1.1Yen/kWh. The feasibility of the fuel cost is certified.
The present study is entrusted from Ministry of Education, Culture, Sports, Science and Technology of Japan.
