THE PRELIMINARY STUDY ON IMPLEMENTING A SIMPLIFIED SOURCE TERMS ESTIMATION PROGRAM FOR EARLY RADIOLOGICAL CONSEQUENCES ANALYSIS

Indonesia possesses numerous potential sites for nuclear power plant development. A fast and comprehensive radiological consequences analysis is required to conduct a preliminary of radionuclide release into the atmosphere, including source terms estimation. One simplified method such estimation use Relative Volatility approach by Kess Booth, published in IAEA TECDOC 1127. The objective this study was evaluate simple tool estimating planned plants facilitate during site evaluation. Input parameters include fuel burn-up, blow-down time, specific heat transfer cladding, coolant debit, using 100 MWe PWR as case study. results indicate slight difference calculated fraction compared previous calculations, indicating need modify Keywords: Source terms, volatility, Release fraction, PWR, SMART
