Japan Atomic Energy Agency has been planning in-situ gas migration test in Horonobe URL, Hokkaido. This paper discusses the optimum gas injection procedure for the test to understand gas migration behaviour in surrounded rock. The stepwise constant gas injection was selected, taking into account domestic and overseas gas related research results. Hydro-mechanical-gas coupling analysis which is able to consider the dissolved methane in Horonobe groundwater was applied to evaluate the gas behaviour. The results have indicated no significant mechanical damages to the rock and have supported the sppropriateness of selected gas injection procedure for the test.

Japan Atomic Energy Agency has been planning 
gas migration test in Horonobe URL, Hokkaido. It is expected that dissolved methane in Horonobe groundwater might have an effect on gas migration behaviour in bedrock. A series of two-phase multi-component analyses by use of GETFLOWS were conducted to understand the influence of dissolved methane. The increase of total gas pressure has been shown due to the existence of dissolved methane. The results also indicated that the injected nitrogen gas volume was influenced by dissolved methane.

To examine the effect of the degradation of rock on the behavior of near field of the repository of high-level radioactive waste disposal, the degradation of rock was examined by submerging the rock sample into saline water for 90 days. By using the damage parameters obtained from the degraded sample, the behavior of the near field was simulated with the varying boundary conditions for one million years. The model used for the analysis was called the damage expansion model considering the volumetric expansion due to damage. It was observed from the analyzed results that the damage would be developed locally at the spring line and crown of repository tunnel. After about one hundred years, the damage evolution would be finished even if the degradation progressed so much.

To investigate the effect of the chemical degradation on the mechanical behavior, the rock samples preserved in the 10 % salt water and distilled water for 90 days are subjected to the unconfined compression test. The rock samples were obtained from 
sp
HRL in Sweden. The damage parameters were identified from the unconfined compression tests for two types of rock samples. Beforehand, the characteristics of the effect of each damage parameter on the mechanical behavior were investigated by numerical simulation. By investigating the change in the damage parameters of the chemically degraded rock, the effect of the chemical degradation was tried to infer through the results of parametric study. Moreover, the 3-D finite element simulation was carried out to examine the effect of change in the damage parameters due to chemical effect in detail.
