Dispersion analysis and radiation consequences from the operation of 160MWt PWR-type SMR in prospective Bengkayang Site, West Kalimantan

Sources of electricity generation in Indonesia still rely on fossils as the main source in meeting domestic needs. In 2020, the Indonesian National Medium-Term Development Plan (RPJMN) 2020-2024 targets a total power plant generated is 14.5 GW. The National Research and Innovation Agency (BRIN) prog...

Description
Summary:Sources of electricity generation in Indonesia still rely on fossils as the main source in meeting domestic needs. In 2020, the Indonesian National Medium-Term Development Plan (RPJMN) 2020-2024 targets a total power plant generated is 14.5 GW. The National Research and Innovation Agency (BRIN) program in the nuclear field is to develop a National Research Priority (PRN) for nuclear energy. The output of nuclear energy program in 2024 is the prototype of the first nuclear power plant in Indonesia. In accordance with the energy grade in West Kalimantan, the Small Modular Reactor (SMR) of the 160MWt PWR was chosen. Preparation for the construction of nuclear power plants requires licensing documents and technology assessments. Study on dispersion analysis and radiation safety assessment of the nuclear reactor is conveyed. The aim of the study is to justify that the radioactive releases from the nuclear reactor is in accordance with the regulations. It also to ensure that the public, and the environment receive the lowest possible radiation dose in accordance with the principle as low as reasonably achievable (ALARA). The study includes the calculation of the reactor core inventory, using software Origen 2.1. The source term released into the environment along with meteorological data is used to calculate radiological consequences using PC-Cream code. The meteorological and spatial data were taken from data gathered by Mempawah weather station (116km from Bengkayang site). The 160MWt PWR-type SMR is postulated to be deployed in the prospective site of Bengkayang, West Kalimantan. Data analysis of the dispersion and the radiological consequences have been obtained for the normal operation of one unit of SMR in the candidate site. The results showed that the dose received surrounding the area was far below the community dose limit value set by the Indonesian Nuclear Energy Regulatory Agency (BAPETEN).
