Fuel and O&M Costs Estimation of High Temperature Gas-cooled Reactors and Its Possibility to be Implemented in Indonesia

Abstract

Abstract This research discussed an estimation of High Temperature Gas-cooled Reactor (HTGR) O&M and fuel cost and the potency of HTGR implementation in Indonesia. The cost estimation was done by using scaling method. The O&M and fuel cost compared with the O&M and fuel cost from others power plants. By using the comparison, it could be known that HTGR potentially could be used or not. This research’s purposes were to obtain an estimation of HTGR O&M and fuel costs for various capacities and to know the possibility of HTGR implementation in Indonesia. The results showed the O&M costs were 59.78 million USD for 600 MWth, 56.63 million USD for 350 MWth, 52.04 million USD for 50 MWth, 51.62 million USD for 30 MWth, and 51.10 million USD for 10 MWth. The fuel costs were 57.28 million USD for 600 MWth, 33.41 million USD for 350 MWth, 9.55 million USD for 100 MWth, 4.77 million USD for 50 MWth, 2.86 million USD for 30 MWth, and 0.95 million USD for 10 MWth. Based on the comparison with fossil power plants in Indonesia, due to the fuel and O&M cost of HTGR were less than or nearly same with the fuel and O&M cost of fossil power plants, it could be concluded that HTGR 600 until 30 MWth had high possibility to be implemented in Indonesia.
