3 Introduction (1) The HTGR R&D Programs has a long history in Indonesia BATAN started the HTGR R&D programs in 1989 with by set-up a team work for a technology assessment of PWR and HTR reactors. In the , BATAN established a team focused on the assessment of HTGR reactors and its heat application Senin, 25 Agustus 2014PUSAT TEKNOLOGI REAKTOR DAN KESELAMATAN NUKLIR, BATAN3

4 Introduction (2) During , several national seminars on the technology and application of HTGT are carried out In the period, stake holders from national oil and gas companies, state companies, universities, government institutes were joined in some assessments with BATAN. In the 1999 – 2005, one center in BATAN had a duty for advanced reactors technology assessment including HTGR (Research Center for Advanced Reactor System) Senin, 19 Agustus 2013PUSAT TEKNOLOGI REAKTOR DAN KESELAMATAN NUKLIR, BATAN4

5 Introduction (3) Participated with HTGR international community, through IAEA (CRP on Evaluation of HTGR Performance), especially benchmark analysis on initial core of HTTR (Japan), HTR-10 China and ASTRA (Russia) (IAEA –TECDOC-1382 and IAEA-TECDOC- 1694) Since 2006, the Center for Reactor Technology and Nuclear Safety has a duty for HTGR R&D programs.
