Indonesia’s National Atomic Energy Agency (Batan) launches a roadmap for its Experimental Power Reactor (Reaktor Daya Eksperimental, RDE) design. The country’s indigenous small modular reactor is expected to have a technical design ready by the end of the year.
The detailed engineering roadmap was announced on 7 March by Geni Rina Sunaryo, Batan’s director of nuclear reactor safety and technology. It’s predicted as a complementary continuation to the 2017 RDE basic engineering design.
Batan said the detailed engineering design document, together with the safety analysis report, will be an important requirement for it to achieve approval for the RDE design from the Indonesia’s Nuclear Energy Regulatory Agency (Bapeten).
The Indonesian government aims to announce the design to the global community during this year’s IAEA General Conference, Batan said.
“The detailed design means that the design is close to construction, and the ultimate goal is to determine how much the RDE will cost,” Sunaryo said.
Batan launched a plan in 2014 to build an 10 MWt RDE at its largest research centre site – the Puspiptek Complex, in Serpong, South Tangerang, Banten – as a first strategic milestone for the introduction of large-scale nuclear power plant fleets into the country. The RDE is a very small sized pebble-bed high temperature gas-cooled reactor (HTGR) with low enriched uranium oxide TRISO fuel.
The pre-project phase began in 2015 in cooperation with Russian-Indonesian consortium RENUKO as consultant for conceptual design. Last year, Batan received a siting licence from Bapeten for the demonstration RDE reactor at its Serpong complex.
Construction of a system test facility that will demonstrate Indonesia’s ability to design and build a portion of the RDE will begin later this year. The test results from the facility will be used as input data in the RDE’s design.
