Abstract

Abstract. Experimental Power Reactor (RDE) is a power reactor with High Temperature Gas cooled Reactor (HTGR). The safety justification of the RDE design is that radiation safety can be guaranteed which guarantees the safety of radiation workers and the community around the RDE site. To ensure the safety of workers and the community and the justification that RDE design meets safety criteria, a study of the zoning of the radiation area in the reactor is needed. The assessment is done based on HTR-10 parameters that types and power are similar to RDE. The research was conducted using computer simulation methods using ORIGEN2.1 and MCNP computer programs. Based on the Regulation of BAPETEN No.4 of 2013, concerning "Protection and Safety of Radiation in the Use of Nuclear Power", article 26 of the Work Area is divided into 2 namely Control areas and Supervision area. The zoning of the work area for radiation workers is determined based on the dosage amount calculated from the calculation of radiation sources, doses and radiation shields designed. The division of work area is determined based on the layout of the reactor building which is designed based on the RDE concept design. Based on the RDE concept design, the reactor building is divided into 4 levels, namely: 1). -12.70 m level; 2). Level ± 0.00 m; 3). Level + 12.70 m; and 4). Level +25.40 m. The results of the radiation dose calculation in RDE and the layout of the RDE design are used to determine the zoning area for radiation workers at each level area. Zoning is estimated in accordance with the rules of the BAPETEN regulatory body. Actions that must be taken for each zoning are also carried out.
