Nuclear Power in Indonesia
(Updated February 2014)
- Indonesia has a greater depth of experience and infrastructure in nuclear technology than any other southeast Asian country except Australia.
- A 30 MW nuclear power plant is planned to be built at Serpong, near Jakarta.
Indonesia's population of 242 million is served by power generation capacity of only 35 GWe, producing 182 billion kWh in 2011. Of this, 81 TWh (44%) came from brown coal, 42 TWh (23%) from oil, 37 TWh (20%) from gas, 12 TWh (7%) from hydro and 9 TWh (5%) from geothermal. It has per capita electricity consumption: 475 kWh/yr, but 36% of the population in 2013 have no access to electricity. The government has targeted a 26% reduction in CO2 emissions by 2020.
With an industrial production growth rate of 10.5%, electricity demand is estimated to reach 450 billion kWh in 2026. At present a low reserve margin with poor power plant availability results in frequent blackouts. The Java-Bali grid system accounts for more than three quarters of Indonesia's electricity demand – 132 TWh in 2012. PT PLN (Persero), the Indonesia Electricity Corporation, projects 55 GWe new capacity by 2021, 38 GWe of this coal-fired. It also plans major grid enhancements on Java, on Sumatra, and Kalimantan, with a HVDC link Sumatra to Java.
About 43% of Indonesia's electricity is generated by oil and gas, so as well as catering for growth in demand in its most populous region, the move to nuclear power will free up oil for export. However, in mid-2012 the National Energy Council (DEN) said that nuclear power was an unlikely last resort in the country.
Following earlier tentative proposals, in 1989 the government initiated a study focused on the Muria Peninsula in central Java and carried out by the National Atomic Energy Agency (BATAN – Badan Tenaga Nuklir Nasional) established in 1958. It led to a comprehensive feasibility study for a 7000 MWe plant, completed in 1996, with Ujung Lemahabang as the specific site, selected for its tectonic stability. Plans for the initial plant on the Muria Peninsula in central Java were then deferred indefinitely early in 1997. A National Nuclear Act was passed in 1997.
Then a 2001 power generation strategy showed that introduction of a nuclear plant on the 500 kV Java-Bali grid would be possible in 2016 for 2 GWe rising to 6-7 GWe in 2025, using proven 1000 MWe technology with investment cost $2000/kWe. The Java-Bali interconnected system accounts for more than three quarters of Indonesia's electricity demand.
Under the 2006 National Electricity Planning Scheme 2006-26 and Presidential Decree #43 in 2006 the project may be given to an Independent Power Producer to build and operate. Sites on the central north coast of Java were then under consideration, with access to the country’s main grid infrastructure. Plans were to call tenders in 2008 for two 1000 MWe units, Muria 1&2, leading to decision in 2010 with construction starting soon after and commercial operation from 2016 and 2017, but these plans were put on hold. Fuel services would be purchased from abroad and fuel would preferably be leased. Used fuel would be stored centrally in the medium term.
The government has said that it has $8 billion earmarked for four nuclear plants of total 6 GWe to be in operation by 2025, and aimed to meet 2% of power demand from nuclear by 2017. It is anticipated that nuclear generation cost would be about 4 cents/kWh (US) compared with 7 c/kWh for oil and gas.
In mid-2010 three sites were being considered for main plants: Muria (central Java, actually 3 locations), Banten (west Java) and Bangka Island (off southern Sumatra to NE, 2 locations: West Bangka and South Bangka). All are on the north shores, away from the tectonic subduction zone. Over 2011-13 BATAN undertook a feasibility study for Bangka, and it signed an agreement with the Bangka-Belitung provincial government. Bangka is far from any active volcano, has low seismic hazard, no tsunami hazard (shallow sea), and low population. Site evaluation of Muntok, West Bangka and Permis, South Bangka, showed both to be suitable for some 10 GWe capacity meeting 40% of the demand in Sumatra, Java and Bali. Most of this capacity would be at the West Bangka site, with 600 MWe at Permis. After a change in provincial government, these Bangka sites seem in doubt.
BATAN’s focus in 2013 shifted to West Kalimantan, using small reactor units suited to the relative lack of grid infrastructure there and where most electricity is imported from Malaysia. Six designs were being evaluated. In November 2013 the Research & Technology Ministry (RISTEK) affirmed its intention of building a small (eg 30 MWe) power reactor, at an unspecified place, possibly from 2015. In December 2013, on the 55th anniversary of founding BATAN, the minister said that a non-commercial power reactor (RDNK) and a gamma irradiation facility would be built by BATAN at Serpong, the site of its largest research reactor, and in February 2014 he was quoted as saying that a 30 MW nuclear power reactor would be built by BATAN at Serpong, near Jakarta.
In July 2007 Korea Electric Power Corp. and Korea Hydro & Nuclear Power Co. (KHNP) signed a memorandum of understanding with Indonesia's PT Medco Energi Internasional to progress a feasibility study on building two 1000 MWe OPR-1000 units from KHNP at a cost of US$ 3 billion. This was part of a wider energy collaboration.
In addition, BATAN has undertaken a pre-feasibility study for a small Korean SMART reactor for power and desalination on Madura island. However, this awaits the building of a reference plant in Korea. Also the province of Gorontalo on Sulawesi was reported to be considering a floating nuclear power plant from Russia, and late in 2007 a cooperation agreement with Japan was signed, envisaging its help in building and operating nuclear power plants.
The Japanese and Indonesian governments signed a cooperation agreement in November 2007 relating to assistance to be provided for the preparation, planning, and promotion of Indonesia's nuclear power development and assistance for public relations activities.
The IAEA has been reviewing the safety aspects of both Muria and Madura proposals, with Indonesia's Nuclear Energy Regulatory Agency – Badan Pengawas Tenaga Nuklir (BAPETEN). It was then looking at the Bangka sites. BAPETEN was established in 1998 and reports directly to the President.
In November 2009 the IAEA undertook an Integrated Nuclear Infrastructure Review mission to Indonesia. Against 19 parameters, ‘no actions needed’ on six, ‘significant actions needed’ on three, and the rest ‘minor actions needed’. In respect to IAEA milestones, the country is at the first: ‘ready to make a knowledgeable commitment’. During the 1980s many technical people were trained in anticipation of nuclear power development then, many of these are still available for the new project.
Russia is keen to export floating nuclear power plants (FNPP), on a fully-serviced basis, to Indonesia as a means of providing power to its smaller inhabited islands.
In December 2013 RISTEK reported the results of a poll conducted by an independent agency PT Iconesia Solution. Community acceptance in Indonesia is increasing, and 76.5% agreed with the development of nuclear science and technology, while 60.4% agreed with developing a nuclear power plant in the country.
Indonesia's safeguards agreement with the IAEA under the NPT entered force in 1980 and the Additional Protocol entered force in 1999. In 1997 it signed the Joint Convention on the Safety of Spent Fuel Management and Radioactive Waste Management.
Indonesia has a number of nuclear-related facilities in operation. BATAN operates three research reactors: in Serpong, Banten on the western outskirts of Jakarta (30 MW), Bandung, west Java (2 MW), and in Yogyakarta, central Java (100 kW).
The Serpong multipurpose reactor, which started up in 1987, is intended to support the introduction of nuclear power to the country. It is in the Litbangyasa Serpong Nuclear Zone, located in the Research Centre for Science and Technology (PUSPIPTEK), Serpong. The main facility here is the 30 MW Multipurpose Reactor GA. Siwabessy (RSG-GAS), but also there are the Centre for Reactor Technology and Nuclear Safety (PTRKN), Centre for Development of Nuclear Informatics (PPIN), Nuclear Device Engineering Centre (NEDC), Radioisotope Radiofarmaka Centre (PRR), Materials Technology Centre for Nuclear Fuel, Radioactive Waste Technology Centre (PTLR), Nuclear Industrial Materials Technology Centre (PTBIN), Centre for Standardization and Nuclear Quality Assurance (PSJMN), and the Centre for Nuclear Technology Partnership (PKTN).
A Government-owned company, PT Batan Teknologi, produces medical and industrial isotopes (including Mo-99) for domestic needs using the facilities in Serpong.
At Yogyakarta, as well as the 100 kW Kartini research reactor there is the Teknologi Accelerator and Process Materials Centre (PTAPB) and the College of Nuclear Technology (STTN). At Bandung the country’s first research reactor was built in 1965, a small Triga mkII which was subsequently boosted to 2 MW, and the site also hosts the Nuclear Materials Technology and Radiometric Centre (PTNBR) where nuclear medicine in the country was established. Friday Market in Jakarta is a larger nuclear establishment, with Isotopes and Radiation Technology Applications Centre (PATIR), Technology Centre for Radiation Safety and Metrology (PTKMR), Nuclear Geology Development Centre (PPGN), Centre for Education and Training, and the Centre for Nuclear Science and Technology Dissemination (PDIN).
The country also has front-end capabilities in ore processing, conversion and fuel fabrication, all at a laboratory scale, though PT Batan Teknologi assembles fuel elements for the research reactors using imported US fuel. There have been no experiments in reprocessing, but BATAN operates a radwaste program including for spent fuel from the research reactors.
There are some uranium resources in Kalimantan, and possibly West Papua. BATAN in September 2010 quoted 53,000 tonnes as high-cost resources: 29,000 t in West Kalimantan and 24,000 t in Bangka Belitung, including some associated with rare earths in monazite by-product from tin mining.
