NUCLEUS SEED MIGRATION TESTING DEVICE OF ROCK BODY FOR DISPOSING STRATUM

摘要

PURPOSE: To enable a migration status of a radioactive species 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 rock body to be tested. ;CONSTITUTION: A title item is provided with a container 1 where a rock body X to be tested is stored and a test liquid is filled, a fluid entrance 2 and a fluid exit 3, an inward flange 4 where the rock body X to be tested is mounted, and a seal member 5 which seals an area between a flange surface and the rock body X to be tested. By penetrating a test liquid in parallel with the rock body X to be tested, a concentration distribution of a radioactive nucleus seed which stays at the rock body X to be tested is made to be equivalent.;COPYRIGHT: (C)1993,JPO&Japio
