A special committee of "Research on the analysis methods for accident consequence of nuclear fuel facilities (NFF)" was organized by the Atomic Energy Society of Japan under the entrustment of JAEA. The committee aims to research on the state-of-the-art of consequence analysis method for Probabilistic Safety Assessment (PSA) of NFF such as fuel reprocessing and fuel fabrication facilities. The objective is to obtain the useful information related to establishing quantitative performance objectives and to risk-informed regulation through qualifying issues needed to be resolved for applying PSA to NFF. The research activities of the committee were mainly focused on the analysis method of consequences for postulated accidents with potentially large consequence in NFF resulting in release of radio active material to the environment. In this technical report, the research results about basic experimental data and method for safety evaluation for fire and explosion incidents were summarized.

Pressure effect of electrical resistivity and AC specific heat in CePtAl

We measured the electrical resistivity and AC-specific heat for a canted ferromagnet CePtAl under pressures using a diamond-anvilpressure cell. With increasing pressure, the magnetic ordering temperature increases monotonously, becomes constant above 8 GPa and then starts to decrease steeply in a narrow pressure region from 10.3 to 10.9 GPa, indicating the first-order like phase transition. The similar pressure dependence of was obtained in the AC-specific heat measurement.

We have succeeded in growing a high-quality single crystal of an antiferromagnet UPdGa by the Ga-flux method with the off-stoichiometric composition of U : Pd : Ga = 1 : 2 : 7.3. The electronic state has been investigated by the de Haas-van Alphen experiment, indicating the similar cylindrical Fermi surfaces as in an antiferromagnet UPtGa. We have also studied the pressure effect by measuring the electrical resistivity. The Nel temperature decreases with increasing pressure and becomes zero at 3.1 GPa. The antiferromagnetic state is changed into the paramagnetic state above 3.1 GPa.
