本検討では、昨年度に検討を行った、ターンテーブル式脱硝転換設備概念に基き、セラミックス製脱硝容器を製作し、硝酸ウラニル溶液を用いたマイクロ波脱硝、焙焼および還元処理による粉末の性状並びに脱硝容器の健全性についての確認を行い、下記の成果を得た。 (1)試験用脱硝容器を製作し、硝酸ウラニル溶液のマイクロ波脱硝を行った結果、通常の発泡体が得られることを確認した。 (2)オーガを用いて脱硝体を粗砕し、均一な粉末が得られる見通しを得た。 (3)焙焼および還元後の粉末について粉末物性を測定し、従前のマイクロ波脱硝粉末とほぼ同等の粉末が得られることを確認した。 (4)試験結果について、ターンテーブル式脱硝転換設備成立性の観点から検討を行い、開発課題を整理した。

In this examination, based on the turntable type denitration conversion equipment concept designed last fiscal year, the denitration contaniner made from ceramics was manufactured, the quality tests of powder obtained by microwave denitration of nitric acid uranium solution, calcination, and reduction were performed. The soundness of a denitration container was also checked, and the following result was obtained. (1)As the result of microwave denitration of nitric acid uranium solution in the manufactured denitration container, the usual foamind object was obtained. (2)Denitration product was roughly milled by auger and the prospet to obtain uniform powder was acquired. (3)Physical properties of the powder after calcination and reduction were measured, and the powder was almost equivalent to the conventional one obtained by microwave denitration. (4)Based on the examination result, the formation nature of turntable type denitration conversion equipment was discussed and the development subject was arranged.
