“Fukushima”: all reactors could be destroyed

Russian Press.

“Fukushima”: all reactors could be destroyed.

I’m sorry for the language – it is a Google translation. I corrected some parts, but all in all it might look unEnglish.

Despite numerous assurances that there is no harmful radiation from Japan, the University of California, Berkeley has now reported that in rain water in San Francisco discovered the radioactive fallout at levels 18,100 times higher than federal drinking water standards.

Emergency “Fukushima”: all reactors may be destroyed around the emergency nuclear power plant , “Fukushima”. Japan is going to spray a special resin and radiating buildings cover a special cloth. Russian experts have said these measures are not adequate. In none of the districts of the Far East (Russian Region) background radiation does not exceed the norm.

Work on the station.


Complete stabilization of the situation at  “Fukushima-1” will require more than a few weeks. It was acknowledged by the chairman of the station owner, Power Corporation, “Tokyo Electric Power. ”
However, he said, there are encouraging signs. “We can see some stability in the state of the fifth or sixth power – said Katsumata. – At the same time failed to reach a final cooling first to the fourth reactor. We’re working right now that is all power. ”

In the first, second, third and fourth reactors tsunami blow brought down the cooling system and power supply. There, elevated temperature reactors, hot spent fuel rods in pools, noted the partial melting of the fuel.

In the lower floors of these units – a very large accumulations of radioactive water, high levels of exposure prevents emergency works. At the same time, the fifth and sixth units safely sealed.

The content of radioactive iodine-131 in seawater near the plant “Fukushima-1 exceeded the local law limiting the rate of 3,355 times. This was announced at a press conference in Tokyo, a representative of the National Agency for Nuclear and Industrial Safety.

Currently, the Japanese government is studying proposals to cover the damaged nuclear reactor domes of special fabric, and there has accumulated an extremely radioactive water pumped into a large tanker. However, the decision on this matter is still pending.

In addition, the Cabinet Secretary of Japan Yukio Edano advised to eliminate all six reactors of NPP Fukushima-1 “after her emergency work will be completed.

Answering the question of whether to eliminate all reactors, although the 5 th and 6 th were practically no damage and safely plugged, Edano said: “Given the situation and attitudes in society, it is obvious. Personally, I recommend to do just that.”

As experts have estimated, the dismantling of reactors may take three decades and cost a nuclear power plant operator Tokyo Electric Power more than 1 trillion yen (12 billion dollars).

Meanwhile, the Japanese Agency for Nuclear and Industrial Safety can be deduced from the Ministry of Economy, Trade and Industry. Prime Minister Naoto Kan is currently investigating this issue.

Liquidators

Workers and engineers, the total number from 500 to 600 people engaged in the elimination of accidents at nuclear power plants will no longer spend the night at the station, where a high level of radiation. This was reported by Minister of Economy, Trade and Industry of Japan Banro Kaieda.

According to him, the night workers will be transported outside the 20-kilometer zone around the “Fukushima-1. “Until now, – he explained – they all remained in the emergency area with high levels of radiation. We need a little bit to improve their situation.”

Increased attention from officials and public to the working conditions at the plant was caused by an interview given to local media officer of the Agency for Nuclear and Industrial Safety. He said that participants of the operation stand up before 6 am, get breakfast 30 fresh biscuits, a 180-millimeter package of vegetable juice and non-stop work until the end of daylight, followed by dinner quick cooking rice with vegetables and canned goods. According to him, the radiation level in the building, where participants spend the night work, is 2-3 mikroziverta per hour, which is 10 times more than the norm for the average person.

The situation in the Far East

None of the districts of the Far East background radiation does not exceed the norm. This was reported in the Far Eastern regional emergencies center based on data from 630 fixed and mobile radiation monitoring stations, analyzing the state of soil, air and water.

In the past day background radiation ranged from 12 to 19 micro-roentgen per hour at a rate of 25-30 micro-roentgen.

Control of air pollution are helicopters MOE and other agencies. The radiation background water areas is measured escorts Sakhalin border control coast guard Russia’s FSB.

The radiation background on the islands that are part of the Sakhalin region, on Wednesday morning was at 5 to 14 micro-roentgen per hour. Increased surveillance of the radiation situation in Sakhalin and the Kuriles are 99 radiation monitoring stations.

In Primorye the radiation situation is normal – 14 micro-roentgen per hour at a rate of 30 micro-roentgen per hour.

According to Russian specialists

Find and secure long-term reliable method of cooling the reactor nuclear power station – the main task of the Japanese nuclear scientists. This opinion was expressed by ITAR-TASS news agency deputy director general of Rosenergoatom Asmolov.

“Now, through these reactors need to pump 50 cubic meters of water per hour, and a small amount” – note the Russian experts, nuclear physicists. Once the reactors are cooled, you can think about what materials and how to close: either their upper part, or all reactors, “- he said.

It was clear from the proposal of Japanese experts with respect to the special paint and special fabric for covering the destroyed reactor core, Asmolov considers frivolous. He compared such proposals with a “statement of seals on the aching tooth.”

In Rosatom added: since, according to information from Japanese nuclear scientists, in the reactor remained 2 MW of heat, and two reactors in general are safe, “should be after the reactors are cooled down, to construct two sarcophagi of durable materials. At the same time they are advised to Japanese colleagues “to adjust to the NPP site with good old tanker tonnage or an old submarine and implement such a vessel collecting water passing through the reactor.”

International situation

International Atomic Energy Agency announced a June 20-24 in Vienna Forum for Nuclear Safety. Earlier, the proposal to convene a conference with the participation of high level representatives of all 150 Member States of IAEA Director-General of the Agency Yukiya Amano. In his view, the lessons of failure on “Fukushima” could be one of those meetings.
