The major problem of the self-shielding methods based on the equivalence principle is the difficulty of calculating the dilution cross section σe with adequate precision. We have proposed a new self-shielding procedure that contains a new technique to calculate dilution cross section. We have compared our method to the generalized Stamm'ler method. Accuracy of each computing approach is determined using reference results obtained from a micro-group slowing-down code named CESCOL.

A new technique was proposed for preparation of LaNi5 powder by direct electrolytic deoxidation of solid La2O3–NiO mixture oxides in molten CaCl2–NaCl. Oxides pellets was sintered and used as cathode. High – density graphite was used as anode. Electrolysis was performed. Current change during electrolysis was recorded. XRD was used to analyse the composition of products. SEM was used to analysis surface and cross section of pellets before sintering, after sintering and after electrolysis. The preparation mechanism and the influences of sintering temperature and cell voltage on electrolytic deoxidation was studied. Results show that the optimum conditions to prepare LaNi5 are:NiO-La2O3(Ni:La=5:1)pellets are formed at 30MPa, sintered at 850°C for 5h, electrolyzed under 3.2V in CaCl2–NaCl melt at 850°C for more than 12 hours.

Two hydraulic problems anticipated from the construction of a dike across Tokyo Bay, i e water circulation and 'harbor paradox' are discussed from results of numerical experiments Especially, a new technique has been devised for the investigation of response characteristics of the bay to obtain all the information by only one run.
