In this investigation, ceramics denitration containers with ball valve units were manufactured and preliminary tests of microwave denitration, calcination and reduction were carried out in last fiscal year. In this fiscal year, a small scale denitration /conversion apparatus with turntable system was designed and manufactured, then a series of microwave denitration/conversion tests was conducted. Feasibility of the denitration/conversion apparatus with turntable system was evaluated by checking powder properties and soundness of apparatus through the series of tests. The summary of the results are as follows;(1).By the series of microwave denitration, calcination, and reduction tests using small scale denitration/conversion apparatus with turntable system manufactured, it is confirmed that there are no critical problem in the apparatus.(2).Checking the powder properties after grinding, it is confirmed that the powder is equivalent of one obtained by conventional microwave denitration /conversion facility.(3).Reduced powder was grinded and pressed to several pellets, then sintered. It was confirmed that high density pellet fuel can be obtained.(4).Studying the test results from the viewpoint of feasibility of denitration/conversion facility with turntable system, the R&D issues were made clear.
