| Abstract: |
| This paper aims to introduce that the main radioactive decay of HLNW and the radiation equipment is used for experiment. The radiation effect on the near-field media (groundwater, bentonite and concrete buffer backfill materials) and the corrosion of container materials are discussed respectively. Although the radiation of nuclear waste has little effect on the buffer backfill materials, the near-field environment of containers become oxidized by the radiation and decomposition of groundwater, and the electrochemical state of the container materials may also change by radiation . Finally, the existing problems and future research directions are pointed out. |
