Deep geological disposal facility for spent nuclear fuel and a simulating apparatus for deep geological disposal facilities of spent nuclear fuel

Abstract

Provided is a deep geological disposal facility for spent nuclear fuel and a simulating apparatus for deep geological disposal facilities of spent nuclear fuel, wherein the engineered barrier consists of a canister, a buffer, a backfill and a supercontainer, while the canister comprises a first membrane layer for withstanding corrosion and pressure with spent nuclear fuel; the buffer is made of a material which make nuclide migration delay in case that nuclide is leaked out of the canister; the backfill is made of a material which limits nuclide migration, as engineered barrier; and the supercontainer consists of a second membrane layer for withstanding corrosion and having a low heat conductivity, and wherein the natural barrier is filled with host rock at a depth of more than 500 meters for delaying nuclide transport when nuclide leaks out and preventing radioactive materials from being leaked out toward environment.
