Analysis of a BWR turbine trip experiment by entire plant simulation with spatial kinetics

An analysis of a BWR turbine trip experiment was performed with the THYDE-NEU code. The plant was treated as a closed coolant system whose pressure ranges to the atmospheric pressure. To simulate an entire plant, it was found necessary to have the moisture separator model and to account for reversible pressure drops at a junction with an area change. A spatial kinetics model without a notion of reactivity was applied. It was confirmed that THYDE-NEU can perform a coupled neutronic and thermal-hydraulic null transient at the hot full power. Among factors influencing spatial kinetics in the turbine trip were the temporal behavior of the bypass valve opening, the thermal non-equilibrium model and the manner in which to express the coolant density used in the table look-up of cross sections. By adjusting these factors, it was found possible to generate the scram signal when the core averaged LPRM output reached the prescribed value. The other calculated results also were found satisfactorily in agreement with the experimental results.

MCD measurement at the Tb $$M$$$$_{4,5}$$-edges of Tb$$_{17}$$Fe$$_{x}$$Co$$_{(83-x)}$$ perpendicular magnetization films

The electronic and spin state of the perpendicular magnetization film Tb$$_{17}$$Fe$$_{x}$$Co$$_{(83-x)}$$ was investigated by means of magnetic circular dichroism spectroscopy for each element. The samples are Tb$$_{17}$$Fe$$_{x}$$Co$$_{(83-x)}$$ while the ratio of a rare-earth metal Tb to transition metals Fe and Co is constant, the composition ratio of Fe and Co is changed. Changing the ratio, we estimated the expected orbital moments $$<$$$$L$$$$_{z}$$$$>$$ of Tb 4f electrons. The macroscopic magnetic property is studied from the microscopic point of view.

Soft X-ray magnetic circular dichroism study of [Co/Pd] multilayered perpendicular magnetic films

The electronic and spin states of [Co/Pd] multilayered perpendicular magnetization films with various seedlayers have been investigated by means of soft X-ray absorption and magnetic circular dichroism spectroscopy at the Co ${it L}$$$_{2,3}$$-edges. The expectation values of the orbital angular momentum $$<$$${it L}$$$_{z}$$$$>$$ and the spin angular momentum $$<$$${it S}$$$_{z}$$$$>$$ of Co atom in the [Co/Pd] multilayered film were estimated using the sum rule. It was found that the seedlayer changes macroscopic magnetic properties of the [Co/Pd] multilayered film without affecting the electronic and spin states of the upper layers of Co.
