The role of natural rock filler in optimizing the radiation protection capacity of the intermediate-level radioactive waste containers

چکیده
The present work aims to optimize the radiation protection efficiency for ion-selective containers used in liquid treatment nuclear power plant (NPP) cooling cycle. Some naturally occurring rocks were examined as filler materials reduce absorbed dose and equivalent dos received from radioactive waste container. Thus, simulated at a distance of 1 m surface container using Monte Carlo simulation. Both rate are reduced by raising thickness. total is 7.66E-20 1.03E-20 Gy, 183.81 24.63 μSv/h, thickness between 0 17 cm, respectively. Also, type significantly affects rate, where redorded rates 24.63, 24.08, 27.63, 33.80, 36.08 μSv/h natural basalt-1, basalt-2, basalt-sill, limestone, rhyolite, mentioned results show that rocks, especially thicker (i.e., cm thickness) basalt-1 gamma emissions wastes inside modified Moreover, an outer cementation concrete wall 15 causes additional decrease dropped 6.63 μSv/h.
