RADIATION RESISTANCE OF BOROSILICATE GLASS TO BETA AND GAMMA RADIATION EVALUATED USING THE ACCELERATED PROTON METHOD

The influence of heavy radiation exposure is considered as an essential criterion for its quality assessment used to demonstrate the safety of intermediate storage under controlled conditions and subsequent final disposal of the waste. Earlier calculations covering a time period of up to 10⁴ years allowed to identify the maximum beta- and gamma-radiation induced dose loads for borosilicate glass (BSS) of a basic composition specifically designed to vitrify liquid HLW from ODC MCC [1]. This study evaluates potential feasibility of applying an accelerated proton beam to simulate radiation damage according to the type of beta-gamma effects produced on the BSS and investigates the consequences of such effects on its properties which is seen as a distinctive feature of this research.

Keywords: radioactive waste, borosilicate glass, radiation resistance, computational modeling, absorbed dose, cyclotron.
