Safety Evaluation of Simulated High-Level Waste Glass Products, (2). Preliminary Tests on Durability of Glass Products in Accelerated Electron Beam Irradiation

摘要

Vitrified products containing high-level wastes with large number of radionuclides must retain radiation stability for long storage periods. The radiation durability of borosilicate glass products with natural zeolite has been studied by leachability test and differential thermal analysis following the irradiation by an accelerated electron beam to 10 exp 10 rads. It was found that the leachability did not increase significantly as a whole though it was slightly affected by the production conditions of the sample. The thermal analysis showed that the energy stored by the irradiation was released at about 180 exp 0 C in heating the product. (Atomindex citation 12:630051)
