We performed spark plasma sintering tests of the cerium dioxide (CeO)-based simulated fuel containing cesium iodide (CsI) for the establishment of synthesis technology of simulated fuel containing volatile fission product (FP) such as cesium (Cs) and iodine (I) which is required for the data acquisition on the FP release behavior. We could successfully fabricate the simulated fuel containing CsI, which had homogeneous distribution of CsI compound, by the spark plasma sintering at lower temperature and in shorter time.

We performed spark plasma sintering tests of the cerium dioxide (CeO)-based simulated fuel containing cesium iodide (CsI), in order to establish a synthesis technology of simulated fuel including volatile fission product (FP) such as cesium (Cs) and iodine (I) for a study on the FP release behavior. We could successfully fabricated the simulated fuel containing CsI by the spark plasma sintering at lower temperature and in shorter time. It has homogeneous distribution of CsI compound in the sintered pellet.

In spent nuclear fuel reprocessing plant, Zr/Ta dissimilar metal joint is used for connect between different devices. And it is known that Ta have susceptibility of hydrogen embrittlement. The other hand, it is not clear that relationship between hydrogen desorption behavior and hydrogen existing state in Ta. This study aims to elucidate the effect of environment for hydrogen desorption behavior on Ta. Thermal desorption spectroscopy (TDS) were carried out after hydrogen charging in 0.9% NaCl solution. Hydrogen desorption started at 873K, 673K and 573K in air, Ar and ultra-high vacuum environment respectively. After TDS in air environment, specimen was covered with TaO
film. After removal of the film, hydrogen desorption was observed from 773K in argon environment. These results suggest that the generation of the TaO film suppresses the hydrogen desorption from Ta. And it shows that when considering the relationship between the existence state of hydrogen in Ta with thermal aging, it is necessary to consider the influence of the TaO film.
