[en] Currently the Indonesian Government is planning to build an Experimental Power Reactor (EPR), which is a nuclear reactor based on HTGR technology. Many things must be prepared to meet the development of RDE in Indonesia, one of them is the aspect of national industrial readiness, both nationally and internationally. Industrial involvement (industrial involvement) is one of the basic infrastructures for the NPP's construction. EPR's construction involves many national and international component's industries that include civil construction services, mechanical industries, electrical industries and architect engineer (A/E) services industries. The RDE system is seen from its components divided into 2 parts, that is Nuclear Island (NI) and Conventional Island (CI). For CI's components, the national industries have many experiences in manufacturing and supplying components in the conventional plant's construction in Indonesia. As for the nuclear island's components, the national industries have no experiences in manufacturing, so that the international industries will supply it. China and Japan are 2 (two) countries among a few countries that are experienced in HTGR's construction. China has built HTR-10 and HTR-PM, while Japan has built HTTR. From their experience in building HTGR, it can be known the involvement of component industries in the nuclear island. The purpose of this paper is to find out and analyze the potency of the international industries ability to participate in the construction of EPR in Indonesia. The method used is a literature study related to international industries that are experienced in manufacturing and supplying nuclear island's components in the construction of HTGR technology-based NPP, which is then carried out by descriptive analysis. The results of the study show that in the construction of the HTR-10 and HTR-PM, The Shanghai Electric Corporation, Dongfang Electric Corporation and Harbin Electric Corporation were given the authority to manufacture and supply components of the nuclear steam supply system (NSSS). Meanwhile, Mitsubishi Heavy Industries (MHI), Fuji Electric, Toshiba, Hitachi, Nuclear Fuel Industries (NFI) and Toyo Tanso have participated in the HTTR project since the beginning in design and supply of equipments & components. The industries involved in the construction of HTR-10, HTR-PM and HTTR have the potency to be involved in the RDE's development in Indonesia. Learning from the experiences of China and Japan to build the HTR-10, HTR-PM and HTTR, BATAN should has involved these industries since the beginning of designing RDE's components until supply the components when constructed it.
