5. Research Reactor In Indonesia • TRIGA 2000 Reactor • Location: Bandung, West Java • Type: TRIGA reactor • Thermal power: 2000 kW • First critical at 1964 (250 kW)‏ • Upgraded to 1000 kW on 1971 • Upgraded to 2000 kW on 2000 • License: valid up to 2016

6. Research Reactor In Indonesia • Kartini Reactor • Location: Yogyakarta (Central Java)‏ • Type: TRIGA reactor • Thermal power: 100 kW • Some components/structures were provided from first upgrading of Bandung reactor (1971)‏ • First critical at 1979 • License: valid up to 2010

7. Research Reactor In Indonesia • G.A. Siwabessy MPR • (RSG-GAS)‏ • Location: Serpong, Banten (West Java)‏ • Type: Multi Purpose Reactor • Thermal power: 30 MW • Fuel: U3Si2Al • First critical at 1987 • License: valid up to 2020

8. Status of Research Reactor In Indonesia • All reactors are in operation  Nuclear Energy National Agency - BATAN • Long time operation periods: • TRIGA 2000 : ± 34 years old • Kartini : ±26 years old • RSG-GAS : ±18 years old • Decommissioning would not be a best choice • Ageing problems are crucial • Ageing would be the main issue for continued operation

9. THE RULES & REGULATION Nuclear Energy Act 10 Year 1997, Chapter II Articles 3 LAW Basic principles in safety arrangement for the development and beneficial use of nuclear energy. Government Regulation “Nuclear Reactors Licensing” No. 43 Year 2006 Government regulations Regulation based on Law Presidential Decree Regulation based on Law Regulations of Chairman of Bapeten • Decree Of the Bapeten Chairman “Safety Provision On Research Reactors Operation” No. 10/99. • Decree Of The Bapeten Chairman “Ageing Management Of Nuclear Installation” (Draft)

10. The licensing For Renewal Operation Licensing Application • Authorisation process for the Research Reactors in Indonesia is governed by the Government Regulation No. 43 Year 2006 on “Licensing For Nuclear Reactors”. • As per the requirements of Government Regulation No. 43 Year 2006, the operating organisation is required to establish certain programmes with respect to plant life management, before authorisation is issued to a Research Reactors license applications

11. Efforts To Approach The Ageing Management Related On The Regulation (1) The SSCs feasibility to operate • to obtain information on behavior of the components, as identified for ageing management purpose, under reactor environment and to undertake necessary studies/experiments with respect to their residual life assessment. • The assessment to the feasibility of operation and the evaluation of Systems, Structure and components (SSCs) capability were accomplished by BAPETEN and by organization operation for the verification of the capability of old nuclear facility in order to guarantee the operation license that the research reactor is still feasible to be operated and to avoid any accident occurred due to incapability of SSCs.

12. Efforts To Approach The Ageing Management Related On The Regulation (2) Ageing management Program • The objective of the management of ageing is to determine and apply the probability of a component, system or structure failure resulting from ageing degradation • The management of ageing includes activities such as protection, repair, refurbishment or replacement, which are similar to other activities carried out at a reactor facility during routine maintenance and testing or when a modification project takes place.

13. Efforts To Approach The Ageing Management Related On The Regulation (3) A yearly maintenance report • As stated on the License Condition periodically the research reactor operating organization have to report to BAPETEN a maintenance report. BAPETEN review the maintenance report. Maintenance report objective is to ensure that (i) Safety Status of the Plant is not adversely affected due to aging, deterioration, degradation or defects of plant structures, systems or components since commencement of operation and (ii) their functional reliability is maintained in accordance with the design assumptions and intent over the operational life span of the plant.

14. Efforts To Approach The Ageing Management Related On The Regulation (4) Periodic Safety review every 5 years • As stated on the License Condition every 5 (five) the operating organization of research reactor have to make a periodic safety review. The periodic safety reviews should include all technical, operational, personnel and administrative aspects of safety related operations. BAPETEN review and assess the periodic safety review. The periodic safety review for SAR objective is to ensure that (i) Safety Status of the Plant is not adversely affected due to aging, deterioration, degradation or defects of plant structures, systems or components since commencement of operation, and (ii) their functional reliability of SSCs is still comply with the requirement.

15. Efforts To Approach The Ageing Management Related On The Regulation (5) Preparation of decommissioning program • As stated on Government Regulation No. 43 Year 2006 3 (three) year before the license operation terminate date the operating organization of research reactor have to plan is there the reactor will continue to operate by request renewal license application or the reactor will be decommissioning. If the research reactor wants to close down the operating organization have to prepare the decommissioning program.

16. ACTIVITIES RELATED TO AGING MANAGEMENT • TRIGA 2000: • has experienced with ageing problems when upgraded to 2000 kW • the reactor tank was replaced with new one • Kartini: • has performed ISI for reactor tank/liner • RSG-GAS: • has performed ISI for reactor tank/liner

17. Conclusions • The research reactor in Indonesia have been performed ageing management activities by: (i) Categorization of SSCs important to safety related to ageing, (ii) In-service inspection for some components. TRIGA 2000 Reactor has experienced with ageing problems when upgraded to 2000 kW and the reactor tank was replaced with new one. Kartini Reactor has performed ISI for reactor tank/liner. RSG-GAS has performed ISI for reactor tank/liner • The research reactor in Indonesia have comply the requirement of Government Regulation Number 43 Year 2006 in implement ageing management.
