A property of a lattice composed of asymmetric unit cells is investigated. It is shown that usual deterministic calculation procedure based on the unit cell homogenization works well even if the unit cell is asymmetric by considering a direction dependence of homogenized total cross sections.

We perform Large-Eddy Simulations (LES) on turbulent flows and plume dispersions within and over regular arrays of cubic buildings with various roughness densities and investigate the influence of the building arrangement pattern on the characteristics of mean and fluctuation concentrations for the assessment of human health hazard from toxic substances and the safety analysis of flammable gas.

A failure mechanism of preirradiated 14
14 type PWR fuel rod was studied. The test specimen at 42 MWd/kgU was segmented by the active column length of 0.12 m (STFR). It was loaded into the JMTR for load follow operation of 35 kW per m (20 min); 20 kW per m (10 min) up to the 300 cycles. The STFR was further pulsed at NSRR with the energy deposition of 118cal per gram and defected by the split mechanism. This failure was affected with burnup (BU), PCMI stress, the hoop stress caused by the transient FGR and the time. Because they are irrelevant to the type of the fuel rod, all LWR fuels preirradiated may be possible to fail by this mechanism.

To understand release behavior of He and fission gases from irradiated fuel, the quantities of He and fission gases accumulated in mixed oxide fuel irradiated in a fast reactor was measured to reveal retaining gas amounts per pin.
