Nuclear Meltdown
March 31, 2011
Nuclear Energy is one of the most important sources of Energy for Humans accounting for almost 15% of the world's electricity capacity.Most of the Developed Countries have installed gigawatts of nuclear power during the heydays of 1960-1980s before the Chernobyl and Three Mile Nuclear Reactor Failures.Nuclear Energy has come into renewed focus after the drastic nuclear accident at the Fukushima Dai-ichi Plant of TEPCO in north Japan.The 6 nuclear reactors have to be decommissioned after most of the safety processes failed at the plant following a massive earthquake.However Nuclear Energy will continue to play a big role as the installed base of nuclear power is too huge and the growing demands of developing countries too large.China and India have massive growth targets for Nuclear Power given its low costs and non-GHG emitting properties.Like Hydroelectricity,Nuclear Electricity is the only large scale baseload source of energy which does not contribute to Global Warming.There are many advantages to nuclear power but the massive tail risks of catastrophic radioactive poisoning is too enormous.This has resulted in a global backlash as people across the world (Germany,India) are protesting to stop Nuclear Power.NIMBY concerns are growing by the day as the fallout from radiation can permanently make a large area inhospitable to human/animal life for many years.Here are the detailed list of the Cons of Nuclear Energy.

The French President Sarkozy has become the first international leader to visit Japan after the Fukushima Dai-ichi Nuclear Disaster which has simmered for more than 3 weeks.Japan and France do not have a strategic relationship like USA and Japan does nor do these countries have shown great friendship in the past.So it surprising why Sarkozy has gone to Japan on such a short notice to pledge all French help to the Japanese in the wake of the radioactivity leaking from the reactors in northern Japan.Note France has been the leader in the Libyan no fly zone as well calling for Western intervention in a mostly domestic civil war.France has not got too much involved in other civil wars raging in the Middle East.It has been selective over it choice for jumping up and down over human rights.The glaring Western and French silence over the Saudi invasion of Bahrain and violent suppression of its citizens by the Middle Eastern dictators tells of a hypocrisy.

China which has the most ambitious growth planned for nuclear energy is already rethinking its target 3 weeks after the Fukushima plant in Japan started spewing out radioactivity.Note there has been a strong global backlash against nuclear energy around the world and 7 nuclear plants in Germany have been closed all but in name.Other countries like South Korea,Italy,Switzerland are rethinking of what do about their nulcear reactors giving the massive tail risks with nuclear generation.Already 2 earlier nuclear disasters in Chernobyl and Three Mile Island had massively damaged the surrounding ecosystem poisoning humans and animals alike with radiation.Japan too may see its land areas near the reactors be quarantined for many years as TEPCO has failed to control the nuclear plant and government will probably pour concrete.

The Reactor 1 of the failed Fukushima Daichi plant might be recritical as Radioactive Chlorine has been detected suggesting chain reactions continued after the reactor shut down.This is quite alarming and has made Japan thing about pouring concrete into its crippled Fukushima atomic plant IEAE warned that a potential uncontrolled chain reaction could cause further radiation leaks.The risk to workers might be greater than previously thought because melted fuel in the No. 1 reactor building may be causing isolated, uncontrolled nuclear chain reactions.Dumping concrete on the plant would serve a second purpose: it would trap contaminated water, said Tony Roulstone, an atomic engineer who directs the University of Cambridge’s masters program in nuclear energy.

The radioactive fallout from the Fukushima Nuclear Disaster is not only keeping Japan on high alert but also its neighbours.China has said that it has detected trace radiation levels from the spreading radiation in its provincial regions bordering Japan.Note most of the Chinese economic centres are situation near the eastern coast near Japan.Its 2 main cities of Guangdong and Shanghai have also detected trace levels of radioactive elements like iodine and caesium.Note China has turned back vessels and people from Japan in the last week because of high radiation levels.

The Fukushima Nuclear Disaster shows more dangerous radiation signs each day.While Plutonium Poisoning was found in the soil near the Nuclear Reactors,a more alarming development is the high levels of Caesium being found in areas far away from the plant.Note Caesium is a heavy element which is found in areas of radioactivity like Iodine 130.Caesium has a much bigger half life than iodine and can cause radiation poisoning for a much longer period.

TEPCO the beleaguered Japanese utility said that plutonium was found around the damaged nuclear reactor.Plutonium has been detected in soil at five locations at the Fukushima No. 1 nuclear power plant, Tokyo Electric Power Co. said in a statement on MondayThe company could not confirm which of the reactors in the plant was leaking plutonium which is a very dangerous radioactive element.The No. 3 reactor is the only one at the six-reactor facility to use plutonium in its fuel mix.The United Nations' International Atomic Energy Agency said the find was expected due to known fuel degradation, however Japan's Nuclear and Industrial Safety Agency is highly worried about the radioactivity of the plutonium samples detected.

Dangerous levels of radiation has been detected in the water around the reactors as the Japanese government says that a partial meltdown has occured.While there is no confirmation about cracks in the pressure and containment vessels around the reactors,the radiation in the water inside Unit 2 has tested at radiation levels some 100,000 times normal amounts.Workers also discovered radioactive water in the deep trenches outside three units, with the airborne radiation levels outside Unit 2 exceeding 1,000 millisieverts per hour _ more than four times the amount that the government considers safe for workers.TEPCO officials said Sunday that radiation in leaking water in Unit 2 was 10 million times above normal.TEPCO has been giving confusing figures for radiation making it all the more difficult in understanding the gravity of the nuclear crisis.Note this disaster is only second to Chernobyl in its scale of radiation destruction.Tokyo and other parts have reported intermittently about high radiation in water and air.A ship from Mitsui was recently turned back from a Chinese port because of high levels of radiation.

India's ambitious nuclear energy plan to add around 2G of Nuclear Plant Capacity is running into more and more hurdles each day.Nuclear Energy in India got a boost when India and USA signed a 123 agreeement which removed India's pariah position in the International Nuclear Community allowing transfer of nuclear equipment and material.However the Japanese Nuclear Disaster has thrown a spanner into the works.The Jaitapur Nuclear Power Plant in Maharashtra was already seeing huge protests from local villages and political parties.The news of the Nuclear Radiation from the Fukushima plant has added fuel to the Nuclear Fire it seems.Note only have the Jaitapur protests become more stringent but another planned plant in Kovvadu village in the south eastern state of Andhra Pradesh has run into trouble.Villagers from all 150 villages took out a rally demanding withdrawal of the proposed nuclear power plant in the wake of ongoing nuclear crisis in Japan.I had earlier written that the Biggest Fallout Effect of the Japanese Nuclear Accident would be the Not in My Backyard (NIMBY) opposition of all existing and proposed Nuclear Energy Reactors globally and this is exactly what is happening.

Japan's Nuclear Crisis has taken a turn for the worse as US Energy Sectratary CHU saying that a Partial Meltdown has occured.Even IAEA has said that the situation has turned very serious with 4 of the reactors suffering from core damage and 3 of the reactors have their spent fuel rods exposed to the atmosphere as cooling systems have failed.While Japan has almost imposed a news blackout,the damaging news comes from the US administration which has said that the crisis exceeds that of the Three Mile Island already.Japan has doubled the number of workers as the crisis continues to escalate.Authorities battling the nuclear disaster at the Fukushima Daiichi power plant have doubled the number of workers on the site to 100.Helicopters have failed to cool the plant using water due to radioactive plumes and now the desperate Japanese are planning to use water cannons to spray the pools.

The situation at the Fukushima Dai-Ichi power plant continued to be desperate as new fires and explosions rocked the nuclear plant.The utility which owns and operates the Nuclear Reactors Tepco said that the containment structure may have been damaged as smoke was seen from top of one of the reactors.70% of the Fuel Rods at Nuclear Reactor 1 and 33% at Reactor 2 have been exposed.This means that these fuel rods are not being cooled and may be melting leading to increased radiation poisoning hazards.New Fire broke out on the morning of 16th March at Reactor No.4 and containment chamber at Reactor 2 is damaged from Reactor 2.The problems at the Nuclear Plant seems to be increasing with no solution in sight.What is worse is that the 2 reactors No.5 and 6 which have been dormant all this time have all seen their temperature .increasing.Temperatures in the spent fuel rod cooling pools of the shuttered No. 5 and No. 6 reactors were rising as of 7 a.m. today to about 60 degrees Celsius (140 degrees Fahrenheit)

The backlash against the new and existing Nuclear Power Plants has started in different places around the world despite defiant expressions by Nuclear Plant Owners and Operators.While China and Italian utility Enel have said that they will go ahead with their billion dollar investment plans,Switzerland and Germany have put nuclear plant extensions on hold.Note Germany had extended the life of Nuclear Plants in the country by 10 years after extensive lobbying by the Nuclear Industry.This had led to huge protests from the Opposition Greens but the government had gone ahead in order to reduce Power Costs.However Merkel has been forced to eat humble pie and has said that a 3 month review will be done to check the safety of the Nuclear Reactors.Switzerland has also come out and put the plans for new Nuclear Reactors on Freeze.

The explosion and fire at the Japanese Nuclear Plant in NorthEast of Japan has led to the release of a small nuclear plume above the reactors.The southern winds have caused this radiation to spread in many of the prefectures in Japan and cesium and other radioactivity has been detected in the capital of Tokyo.Note Radiation does not affect the human body in small doses as radiation is present in our everyday lives at well.However the increase in radiation concentration can lead to severe health hazards and in extreme cases even death.It is almost impossible to escape radiation effects unless one has special nuclear,biological warfare protective equipment.Note Radiation in Japan is still at quite mild levels and seems unlikely to cause any major health hazard.Radiation will need to increase about 1000 times from the current level for the situation to become serious as of now

This Nuclear Energy Disaster in the Age of Twitter and Facebook will vehemently increase the opposition to the setting up of big Nuclear Plants.The Radiation Leak and subsequent health hazards will make it impossible for a Nuclear Reactor to be located except in very remote areas like the Sahara Desert.NIMBY protests are going to almost kill the Nuclear Industry in the next decade at least in democracies.The Nuclear Industry will take a long time in establishing its trust amongst the citizens.Without Nuclear Energy,the other major forms of Renewable Energy ,Solar and Wind Energy have to gain.Already Switzerland and Germany are deferring the planning and extension of Nuclear Energy.Other countries are putting safety reviews.Note the costs of environment regulation and nuclear waste disposal are already quite high.This will make new nuclear plants uneconomical as they are already facing huge cost overruns . Ask Areva in Finland and Constellation in the US.

Japan's Nuclear Disaster took a turn for the worse as another Fire and Blast in the Nuclear Reactor led to Severe Radiation Leak.Japan's PM warned people within 20 miles of the Plant to evacuate and within 30 miles to remain indoors.There is a high probability of the Nuclear Containment Vessel may get Damaged as Temperatures kept rising with the failure of the Cooling Systems.Radiation Levels at the reactor reached 965.5 micro sievert per hour, later jumping to 8,217 micro sievert at 8:31 p.m. The level would be more than eight times the 1,000 micro sievert limit to which people can be exposed in one year without effect, according to the report.The Wind was blowing south which implies that one of the highest population density cities in the world - Tokyo might feel the affects of Radiation.Prime Minister Naoto Kan urged calm in a national address Tuesday.

The Tsunami Nuclear Energy Disaster which is unfolding in Japan highlights that Nuclear Energy can cause some very serious damage though the safety of the nuclear reactors are highly touted in the media by the Nuclear Energy Industry.These Nuclear Plants in Japan are quite old but so are most of the Nuclear Energy facilities in the West.Most of these Nuclear Plants are susceptible to serious natural disasters like earthquakes and tsunamis.In case of a nuclear meltdown the radiation from the Nuclear Plants can not only cause more deaths and injuries from natural causes but also make the area around the Nuclear Plant uninhabitable for hundreds of years.India and China are on a major Nuclear Energy Building Spree even though their nuclear plants have faced minor accidents in recent years.With this Nuclear Disaster,the protests in the se countries are set to grow with NIMBY becoming the biggest hurdle.Already protests are being held in Jaitapur in Maharashtra over damage to the ecology,expect the Japan's nuclear reactor incident to basically kill this Areva-NPCIL plant.Nuclear plants in the US and Europe are already facing huge cost and time overruns.This new problem should cause those projects to also die off.
