The cathodic protection applications of reprocessing plant made of stainless steel in boiling nitric acid solutions was studied. In this study, 304ULC stainless steels in 3N HNO
solutions was investigated, Saturated Silver chloride Electrode (SSE) was used as reference electrode. Results of potentiostatic corrosion test was that corrosion rates shows an exponential function increase with rises of potential in transpassive state regions and finded possibility of the cathodic protection applications. Corrosion rates with cathodic protection was about one fortieth of without cathodic protection in boiling nitric acid solutions added 10 g/L vanadium ions (imitation solutions of reprocessing).

One of the major causes of JCO criticality accident is that the change of procedure of homogenization of product solution from the storage tank into the precipitation tank was permitted by the manager of planning group. Unofficial duty handing over by the retiring manager of the special crew (SC) influenced significantly the foreman's cognition that the SC foreman had the role and authority to ask the permission.

In order to improve accuracy of effective cross section calculations for MA and FP nuclides, we propose a new method in which a detail energy spectrum of neutron flux, which is depressed by the uranium-238 resonances, is utilized in the generation process of multi-group libraries. We produced a 107-group multi-group library with the proposed method, and utilized it for a burn-up calculation of LWR pincells. We found that this library predicts the number densities of MA and FP nuclides after burn-up very well.

In the metal electrorefining reprocessing method, transuranic elements (TRU) are recovered simultaneously with the liquid cadmium cathode (LCC) and are decontaminated from the fission products dissolving in the melt. Lab-scale experiments were carried out to evaluate the performance of TRU recoverly with LCC using U, Pu and minor actinides (MA), and it was confirmed that TRU could be recoverd simultaneously with LCC by electrode position.
