Japan to export safer nuclear reactor to Poland


Japan to export safer nuclear reactor to Poland

Public-private team faces competition from China and Russia

TOKYO -- A Japanese consortium is looking to commercialize next-generation reactor technology in Poland by 2030, betting that proven expertise in safer and more cost-effective nuclear power will help to secure orders from around the world.


The Japan Atomic Energy Agency and companies including Toshiba, Mitsubishi Heavy Industries and Hitachi will take the lead on building a commercial high-temperature gas-cooled reactor after Japan and Poland sign an agreement on the matter, potentially at the start of next year. The two countries formed a partnership on HTGR technology in May.


This team plans to join with local partners in 2018, and begin operations at the 160-megawatt facility in 2030. The goal is to complete a 10MW experimental reactor at Poland's National Center for Nuclear Research by 2025.



A commercial reactor is said to cost around 50 billion yen ($441 million). The project is expected to generate orders worth 50 billion yen to 100 billion yen in all.


HTGR technology has yet to be commercialized anywhere in the world. But the JAEA has made substantial progress toward this next technological step with a 30MW experimental unit in Ibaraki Prefecture, north of Tokyo. The agency has already sent engineers to Poland to conduct preliminary surveys for the commercial reactor project.




Better and safer

HGTRs run on uranium, like conventional reactors, but are cooled with helium rather than with water, eliminating the risk that the coolant will evaporate, react chemically with some part of the reactor system or produce hydrogen that can then explode. Helium-cooled reactors are also said to be safer because they resist core meltdowns even if cooling equipment loses power.


The reactors require less plant than traditional light-water reactors to produce the same amount of electricity, lowering generating costs per unit of electricity by around 30%. They entail fewer carbon dioxide emissions as well, and are expected to use up just one-quarter the fuel of today's reactors.


Japan hopes these advantages will bring robust overseas demand, which has been lacking for the country's current nuclear technologies. The government would like to see Japanese contractors win orders worth 30 trillion yen for overseas infrastructure projects by 2020 -- triple the 2010 level. But nuclear power projects have done little so far to bring that goal within reach. Plans for Japanese-built reactors in Vietnam were recently scrapped, and the memory of the March 2011 meltdowns at Tokyo Electric Power Co. Holdings' Fukushima Daiichi plant looms large in many potential buyers' minds.
