Introduction 1

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 1993-1998, BATAN established a team focused on the assessment of HTGR reactors and its heat application

Introduction 2

Introduction (2)

  • During 1993-1998, 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)

Introduction 3

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.

User consideration of htgr reactor 1

User Consideration of HTGRReactor (1)

  • Based on the National Medium – Term Development Plan (2010-2014) from Presidential Regulation of The Republic Indonesia No. 5/2010: “….to carry out the conceptual design of core, conversion and safety system for the advance reactor …”

  • Center for Reactor Technology and Nuclear Safety (BATAN) implemented it in carrying out a conceptual design of HTGR reactor

User consideration of htgr reactor 2

User Consideration of HTGRReactor (2)

  • We started a conceptual design by making a User Consideration Document (UCD) in the year of 2010

  • The assessment was carried out based on the site of Bangka Belitung Island (study by the Center for Nuclear Energy Development)

Problems 1

Problems (1)

  • Using obsolete code, such as VSOP-94

  • The pebble-HTGR transient analysis codes are needed, such as water ingress, reactivity insertion

  • Benchmark data for transient cases of HTGR reactor are needed

  • Human resources experiences in HTGR system are so minimal, such as helium inventory system, fuel management mechanism, I&C etc.

Problems 2

Problems (2)

  • The IAEA HTGR Review Team (6 experts) will review the HTGR R&D program in BATAN including fuel aspects

  • In the review meeting some softwares/codes will be delivered to BATAN

Summary 1

Summary (1)

  • BATAN has a long history in the HTGR R&D program

  • During initial core in HTTR-Japan and HTR-10-China, BATAN participated in the IAEA CRP among advanced countries in HTGR reactor technology (IAEA-TECDOCs)

  • The 200 MW (th) HTGR conceptual design has been carried out since 2010 based on the feasibility study in the Bangka Belitung island

Summary 2

Summary (2)

  • The core, primary and secondary circuits of the core have been designed

  • In the year of 2014, the conceptual design will be finished

  • The IAEA technical assistances are needed for finishing the design especially in the safety aspect point of view, as well as preparing the HTGR R&D road map in BATAN
