Nikkei: Japan weighs exports of safer, next-gen nuclear reactors

Order from Poland, worth as much as $9bn, may be there for the taking

TOKYO — Japan’s government is mulling plans to export next-generation nuclear reactors that promise a greater degree of safety, with Poland lined up as the probable first destination.

The move, which would involve high temperature gas reactors, or HTGRs, is part of the government’s infrastructure export strategy. Poland, which is turning to nuclear power as a cleaner energy option, is looking at acquiring about 20 such reactors — equipment worth more than 1 trillion yen ($9 billion).

Tokyo will inform Poland of its intentions by the end of this month at the earliest — though it may face competition from China for the order.

The reactors in question use helium gas as a coolant, unlike conventional reactors that use water. This removes the risk of chemical reactions and vaporization — and thus the risk of hydrogen or steam explosions.
