Description

High level radioactive waste are ultimately disposed of 500-1000m deep in the earth, and at this depth, about 5-40MPa pressure is exerted to the wastes, etc. However, since no thoroughgoing evaluation has been made on the effects of the pressure of the above-mentioned level on chemical actions, etc., in situ solubility measurement apparatus that can measure in situ the solubility and pH under high pressure was developed and some data have been generated.
