NUCLEAR SPECIES MIGRATION TESTING DEVICE OF EARTH

摘要

PURPOSE: To enable a migration status of a nuclear species of an earth at a part where a stratum is to be disposed to be understood accurately in a state which is simulated to an actual disposal environment by using a small amount of earth sample. ;CONSTITUTION: A side wall 2c where a communication hole 2d is provided, a screening wall 2e which covers the inside, and a porous plate 3 where a high-pressure plenum part 3a and a low-pressure plenum part 3b are formed are provided at a test container 2 where an earth sample S is stored. By deforming the side wall 2c which isolates the earth sample S toward an inside. a test liquid can be penetrated in parallel in up and down directions while a side pressure is applied to the earth sample S.;COPYRIGHT: (C)1993,JPO&Japio
