Fukushima - China and Japan hold consultations
Japan and China held a consultation last month on the dumping of tritium-contaminated water into the ocean from the site of the Fukushima Daiichi nuclear power plant.
This is stated in an article published in the Japan Times. In accordance with the terminology adopted in Japan, the original article calls the water as treated, not as contaminated with tritium.
At the meeting, as sources close to the topic told reporters, the issue of China ban on imports of marine products from Japan was also discussed.
The consultation was organized online. It is claimed that the parties were unable to make significant progress, as China, despite Japan request, kept the import ban in force.

Fukushima water - NRA gave the go-ahead
Japanese Nuclear Regulatory Agency (NRA) has approved TEPCO plan to dump tritium-contaminated water accumulated at the site of the Fukushima Daiichi emergency nuclear power plant into the ocean.
The official approval was preceded by a 30-day public comment period.
The contaminated water is stored at the site in about a thousand tanks. This is water purified after passing through a specialized ALPS system, which is capable of removing most radioactive isotopes, except tritium.
The volume of stored water is gradually increasing, despite all efforts to reduce the rate of its accumulation. Now it is about 1.37 million cubic meters. According to forecasts, the existing tanks will be fully filled in the middle...

Fukushima Daiichi - Drop in Water Levels
On February 18, as parameters, such as primary containment vessel water levels and temperature, were being monitored, the Unit 1 primary containment vessel experienced a drop in water level.
As a result, other parameters were checked and it was found that some of the temperature gauges in the primary containment vessels for Unit 1 and Unit 3 have been showing decreasing trends since February 15 and February 17, respectively.
Therefore, we have been assessing related parameters since February 18, and today February 19 we determined that water levels in the Unit 1 and Unit 3 primary containment vessels are decreasing.
Furthermore, since no significant fluctuations...

Some commentators like to use arithmetic to compare various international organizations. If we add up the annual GDP of China (the world's second largest economy), Japan (the third largest economy) and South Korea (whose GDP is nothing to sneeze at) and compare the sum to the GDPs of the G8, which also includes Japan...nothing will happen. This is a senseless exercise because regional and international organizations are not created to flex muscles - economic or otherwise.
The GA is merely a top-level forum for discussing and regulating the ongoing formation of a common economic space in this part of the world. ASEAN performs a similar function in Southeast Asia. The purpose of these organizations is completely clear. The G8, meanwhile, appears no longer to serve a purpose.
But the GA is a special case. There are few organizations in the world where the members have such long-standing animosity toward one another. For example, while Japanese Prime Minister Naoto Kan, his Chinese counterpart Wen Jiabao and South Korean President Lee Myung-bak have agreed on new plans for cooperation.

Lead-bismuth CANDLE - Japanese challenge for SVBR
Lead-bismuth fast neutron technologies in Russia are close to the demonstration. According to the declaration of the director of the energetic machine building department of the Russian machines company Vladimir Petrochenko, the first NPP with SVBR-100 reactor can be built in Obninsk in 2015.
But Russian SVBR has foreign rivals. One of them can become Japanese lead-bismuth reactor that is using the CANDLE burnup conception.
Reactors of high capacity, as it is well known, can be placed only in the regions with high energetic demands or/and developed nets. For the bigger part of countries such monsters as EPR-1600 or APWR-1700 can be elementary useless - countries of the third world won't be able to consume the produced amounts of electricity.
Besides, developing countries would prefer minimizing possible efforts on behalf of nuclear reactors. Ideally, facilities that don't demand or demand next to nothing servicing during the operation that would be brought to the site by the deliverers, assembled and after the campaign would be returned back to the country of manufacturer would suit them.
Masako Saito: plutonium denaturation is important due to global risk of nuclear proliferation
The main idea is to increase the part of the 238Pu either by transmutation of the minor actinides or by increasing of 235U enrichment in the uranium fuel.
Why 238Pu is important for the denaturing of plutonium? This is because of his huge decay heat. Also the spontaneous fission of 238Pu produces a lot of neutrons.
Why is it so important to denaturate plutonium? It is because of the non-proliferation. A lot of countries want to use the nuclear technology in the near future. It means the global risk of nuclear proliferation will increase. So, the security problems will be much more important in this century, and you must solve it.

Quake hits Japanese nuclear plant: a Russian view
I saw a burning transformer on the television. It was no shock to a specialist-a tank transformer can catch fire with the slightest spark. Every project envisages safety measures. Transformers are set apart from each other, so fire cannot spread to cause a leak. Radioactive water could have leaked from the reactor containment sump-but I don't think it could get out of the circuit and pollute the environment, whatever the press might be saying. As for polluted sea, I think that's a paranoid allegation.
The expert dismisses speculation that seismic danger was underestimated when the plant site was chosen: The Japanese are top-notch professionals, and exacting and pragmatic to the utmost degree in choosing plant sites. It was a mere accident, I think.
