The LDP won last week's elections in Japan. Shinzo Abe is the new prime minister and has promised to reverse the previous government's stance on nuclear power. The LDP is pro-nuclear and has indicated that the nuclear power plants in Japan will be started up again. More interesting is what will happen to nuclear energy research in Japan in the aftermath of Fukushima. Could it be an opportunity to investigate safer nuclear technologies, such as molten salt reactors ? The late Dr. Furukawa was a big proponent of MSR's inside and outside Japan. Furthermore, China, a strategic rival of Japan, is investing in molten salt reactor technology. Are MSRs really a better alternative than other reactor types such as LWRs, in a country which cares about earthquakes and tsunami's ?

Interesting follow-up. From the NY Times:

Shinzo Abe endorses nuclear power and hints at reactors which will be "completely different from those at the Fukushima Daiichi nuclear power plant". What could he have in mind ?

It is such a waste to give up nuclear energy, which produced a third of Japan's power just because a few of older reactors were damaged due to unprecedented earthquake and tsunami in living history. Japanese are too knowledgeable for sense not to prevail in due course.
If the geological fault lines or vulnerability to earthquakes or tsunami limit the sites, They could also build floating power plants and anchor them where required. Russians have already made a start.
The Japanese have a lot of Plutonium from reprocessing in France/UK/Japan. They could set up uranium/thorium breeders using it as fuel as originally planned. They have already done a lot of R&D. After bad experience with sodium as coolant, they could shift to lead or salt instead of just giving up.

Its just a matter of time until the pressure of 100's of billions of lost production from shut down nuclear plants forces them to restart.

The Japanese have had a major sodium fast reactor program for some time. Results from the MONJU were very poor, but he could be talking about the newer passively safe pool type or hybrid loop/pool type sodium fast reactors.

The latest BWRs offered by Japanese heavy industrial companies are also passively safe (have full decay heat shutdown cooling even in full station blackout). ABWR-II, Toshiba's EU-ABWR, GE's ESBWR and the French BWR design Kerena (formerly SWR1000) all have shutdown cooling systems that don't need electricity.

My guess that eithere these passive SFRs or passive BWRs are meant by Shinzo Abe. Probably not MSRs, the Japanese have not done much work here.
