“…In order to complete the safety assessment objective, there are some parameters need to be evaluated from the design of the concrete vault. The parameters needed are the properties of soil layers around the vault and the magnitude of the degradation of the concrete based on the variations of infiltration rate [6]. In addition, it should also need to be studied the effects of radiation from the nuclear waste disposal system includes structural effects, thermal effects, the effects of diffusion and hydrological effects on the strength of the concrete vault in the long term period [8].…”

“…The limit of radiation amount received by workers (average effective dose) is 20 mSv/year and for the public is 1 mSv/year and the criteria of the radiation area of very low dose rate is 0.3 μSv/h [2]. A study related to vault disposal facility has been done by a previous researcher [6]. Underground concrete vault is used to store contaminated material as hazardous waste and radioactive waste in the long term period.…”

In order to support and complement the radioactive waste management facilities in Indonesia, BATAN will build a demonstration disposal facility in Serpong Nuclear Area (SNA). Demonstration disposal that will be built is Near Surface Disposal (NSD) type. Engineered vault for NSD is reinforced concrete. The calculations for determining the thickness of NSD concrete vault is based on the conceptual design as the result of the placement optimization of demonstration disposal that takes into account the inventory of radioactive waste and environmental geology conditions of the site at Serpong Nuclear Area. The thickness of the vault in this paper is focused on its ability to withstand radiation from stored waste so that workers or people who are around the disposal facility is safe with maximum radiation dose limit rate of 0.3 μSv / h. The calculation is performed with the aid of MicroShield 7:02 and Rad Pro Calculator Version 3:26 software. From the calculation so that the dose rate at the outer surface of the vault to be 0.3 μSv / h, required walls made of concrete with a density of 2:35 g / cm3 is 62.8 cm thickness.
