In order to establish the synthesis method of simulated fuel contacting Cesium (Cs) which is required for the evaluation of physical/chemical characteristics in fuel and release behavior of Cs, sintering tests of the cerium dioxide (CeO$$_{2}$$) based simulated fuels containing Cesium iodide (CsI) are performed by using spark plasma sintering (SPS) method. The sintered CeO$$_{2}$$ pellets with homogeneous distribution of several micro meter of CsI spherical precipitates were successfully obtained by optimizing SPS conditions.

The Upper pliocene diatom zone and fission-track age of the upper Koetoi Formation around the Sarobetsu anticline, northern Hokkaido

Yasue, Kenichi; Akiba, Fumio*; Ohira, Hiroto*; Ishii, Eiichi

Chishitsugaku Zasshi, 112(4), p.284 - 293, 2006/04

The Upper Pliocene Neodenticula koizumii Zone was recognized near the boundary between the Koetoi and Yuchi Formations in the western part of the Horonobe area, northern Hokkaido. In previous studies, numerous reworked fossil diatoms from underlying strata have obscured the recognition of the zone. However, this study samples include commonly both N. seminae and N. koizumii as probable autochthonous diatoms and almost no reworked fossil diatoms. Therefore, the samples belong obviously to the Neodenticula koizumii Zone. In addition, fission track ages of zircon crystals from a tuff between the diatom samples show 2.2$$pm$$0.1 Ma and 2.3$$pm$$0.1 Ma (2.5$$pm$$0.1 Ma:). The diatoms and FT age data indicate that the depositional age around the boundary between the Koetoi and Yuchi Formations in the study area is 2.1-2.4 Ma. The age is younger than that in the eastern part of the Horonobe area for about one million years, which is concordant with the previously suggested westward migration of the Tenpoku Basin after Pliocene.

Synthesis of CeO$$_{2}$$ based simulated fuel containing CsI to evaluate the release behavior of Cs and I

We performed spark plasma sintering tests of the cerium dioxide (CeO$$_{2}$$)-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.
