In 2009, NUMO and JAEA set up a technical commission to investigate the reasonable TRU waste disposal following a cooperation agreement between these two organizations. In this report, the calculation result of radionuclide transport for a TRU waste geological disposal system was described, by using the TIGER code and the GoldSim code at identical terms. Comparing the calculation result, a big difference was not seen. Therefore, the reliability of both codes was able to be confirmed. Moreover, the influence on the disposal site design (Disposal capacity: 19,000 m
) was examined when 10% of the amount of TRU waste increased. As a result, it was confirmed that the influence of the site design was very little based on the concept of the Second Progress Report on Research and Development for TRU Waste Disposal in Japan.

Phosphate glasses have received much attention for the development of new low-melting glasses with low environmental load. However, their low chemical durability prevents their application for practical use. Recently, the addition of Fe
O
was found to improve their chemical durability. Due to their high durability and high capacity of solution of dopants, iron phosphate glass system has been suggested to be utilized as new materials. In this work, the effect of the addition of other transition metal oxides on the properties of iron phosphate glass was investigated. In addition, the pseudo fission products as nuclear waste was added and their glass formation and chemical durability were investigated. All the glass batches formed homogenous melts at 1250 in the centigrade scale and vitrified without crystallization by pouring on the carbon plate. It was found that the substitution of a part of FeO by MnO or CoO did not cause large changes in the thermal properties.
