Update last hour -

Quote:Fukushima Daiichi The reactors at the Fukushima Daiichi plant are in stable condition and are being cooled with seawater, but workers at the plant continue efforts to add cooling water to fuel pools at reactors 3 and 4.



[color="#FF0000"]The status of the reactors at the site is as follows:[/color]



Reactor 1’s primary containment is believed to be intact and the reactor is in a stable condition. Seawater injection into the reactor is continuing.



Reactor 2 is in stable condition with seawater injection continuing. The reactor’s primary containment may not have been breached, Tokyo Electric Power Co. and World Association of Nuclear Operators officials said on Thursday.



Access problems at the site have delayed connection of a temporary cable to restore off-site electricity. The connection will provide power to the control rod drive pump, instrumentation, batteries and the control room. Power has not been available at the site since the earthquake on March 11.



Reactor 3 is in stable condition with seawater injection continuing. The primary containment is believed to be intact. Pressure in the containment has fluctuated due to venting of the reactor containment structure.



TEPCO officials say that although one side of the concrete wall of the fuel pool structure has collapsed, the steel liner of the pool remains intact, based on aerial photos of the reactor taken on March 17. The pool still has water providing some cooling for the fuel; however, helicopters dropped water on the reactor four times during the morning (Japan time) on March 17. Water also was sprayed at reactor 4 using high-pressure water cannons.



Reactors 5 and 6 were both shut down before the quake occurred. Primary and secondary containments are intact at both reactors. Temperature instruments in the spent fuel pools at reactors 5 and 6 are operational, and temperatures are being maintained at about 62 degrees Celsius. TEPCO is continuing efforts to restore power at reactor 5.

Quote:TORONTO - Canada's nuclear regulator says a leak at a power plant in Ontario caused more than 19,200 gallons (73,000 liters) of demineralized water to be released into Lake Ontario, but there is [color="#FF0000"]no significant risks [/color]to public health.



The Canadian Nuclear Safety Commission said Wednesday that the water was released from the Ontario Power Generation plant in Pickering, Ontario, around 11:30 p.m. Monday. The agency says the leak was caused by pump seal failure.



Ontario Power Generation says the leak was stopped immediately and the pump seal is being replaced.



The plant says the filtered water contained trace amounts of tritium — far below any regulatory limits — and should have no impact on the quality of the drinking water, some of which is sourced from Lake Ontario.

Yes, it is a valid question. However, we know the answer. The value of human life is low in the eyes of the authorities who run India. Every year 130,000 people die of traffic accidents. Nothing is done to reduce it or it is possible that it would be too expensive to reduce it. Every year 400 women out of 100000 die during child birth. The comparable figure in the western world is less than 10. Government expenditure on health is less than 2 % of the miniscule Indian GDP compared to the massive 10 % of GDP in developed countries. These statistics suggest that the benefits of plentiful electricity from nuclear power plants far outweigh any harmful effects. I would say that it would be towards the end of this century that we would be in a position to worry about any harmful effects of nuclear power.

Quote:Updates With News of Resumption of Cooling in Reactors 4 and 5 --Work Continuing to Restart Cooling in Reactors 1 and 2 --TEPCO Expects to Connect Power to All Reactors by Sunday --Acceptable Radiation Level Raised After Workers Surpass Limit
Quote:Water spraying continued overnight as officials worked to keep temperatures down in the cooling pond of the key Reactor 3, whose fuel rods contains plutonium, which is particularly toxic.
Quote:TEPCO said Saturday that it was raising the maximum acceptable exposure for its workers to 150 millisieverts after a number of them showed exposure greater than 100 millisieverts, the previous maximum. It said, however, that it would not send workers back in to the plant once they have been exposed to more than 100 millisieverts.

A typical CT scan exposes a patient to 10 millisieverts.

Quote:India's development of thorium for nuclear power generation caught world interest in the light of the blasts at Japan's nuclear power stations. CNBC-TV18’s Sanjay Suri and Anup Gomen report.



India is considered as the world leader in thorium. The Kakrapar-1 reactor located near Surat in Gujarat is the world's first reactor which uses thorium than depleted uranium for vital power generation. Compated to uranium, thorium has less fissile. The nuclear physicists are now looking at thorium as the safer model.



Ian Hore-Lacy from World Nuclear Association said, "India is the only country in the world that develops thorium fuel cycle. The expertise in India is world class and it is applied very rigorously to the safety of nuclear plants in India."



India has about 25% of the world's thorium reserves and is keen to tap thorium for the growing needs of its population," Hore-Lacy added.



Paddy Regan, Professor of Nuclear Physics from University of Surrey said, “India has a population of a billion people and has massive reserves of thorium. India's nuclear programme, based on the thorium cycle, is slightly different. Indian model thorium based reactors seem to be a very sensible way to go."



Pioneering Indian technology using thorium rather than uranium generated new interest around the world. Thorium is considered less efficient but certainly is much safer. In the light of what has happened in Japan, critics are less inclined to dismiss thorium than they were before.

Thorium based reactors by definition are immune to core meltdown.



However its spent fuel rods is no less hot than other types of fissile material for initial few weeks and months.



Unlike other fuel cycle, however Thorium fuel spent rods have actinides with much longer half cycle for strong Gamma ray radiation, that requires remote robotic handling for re-processing. However some new physical processes have been invented (ultrasonics) that reduce the half life of those actinides by many orders (i.e. 100 to 1000 times). That invention makes Thorium a very good low mining foot print source of clean energy, that is also proliferation resistant (to lay Abduls as well as any country other than top 10 nations which are already in NSG and India (but not Saudi Arabia, Libya, Iran or Pakistan). Not to mention many time larger total available energy from Thorium from global reserves.

Arunji,



Another option would be use of AVLIS (atomic vapour laser isotope separation) to separate U232 from U233. It is known that the U.S in late 80's had developed AVLIS plants to turn RGPu from LWRs into WGPu (though the program was closed in the early 1990's after the cold war ended). Needless to say, AVLIS if well developed, could be useful to clean our own RGPu stocks....Hope DAE has advanced in this direction...

IMVHO the problem is doing the separation it in presence of hard Gamma emitting actinides. The new invention allows forcibly decaying the material at much faster rate so that reprocessing cost can be brought down and solve the radio active waste storage problem.

Quote:In a written statement, the Environmental Protection Agency said that results from a screening sample taken March 25 from Spokane, Wash., detected 0.8 pCi/L of iodine-131. That would be more than 5,000 times lower than the Derived Intervention Level set by the U.S. Food and Drug Administration, the agency said.



The EPA statement said it has increased the level of radiation monitoring in response to the radiation leaks from the earthquake stricken Fukushima Daiichi nuclear complex in Japan. The agency said it expects more findings of radiation "in the coming days" but added that they are "far below levels of public health concern, including for infants and children."



Iodine-131 has a half life of approximately eight days, and the level detected in milk and milk products is therefore expected to drop relatively quickly, the agency said.

From a post in my blog @ http://indicrace.blogspot.com/2011/05/au...ouses.html



You really have to credit the Australians. I would categorize them as the most barbaric of cultures (well if you could call it one). When they act all civilized and polite and "accepting" it is hard to keep a straight face and think of all the crimes that these descendants of convicts have perpetrated in the last 200 years of their miserable existence. That not many native aborigine Australians survive today to tell us of these crimes is another matter. The Australians of today will give the British, the Americans and the Soviets a run for their money when it comes to cruelty meted out under the cloak of sham altruism. We will keep this topic aside, now let us discuss the main topic of Australians and their concerns on India especially after the Japanese nuclear crisis. If the technologically advanced Japanese struggle so much what would the lowly Indians do they asked in one of their online news articles I remember reading, I will post the link as soon as I run into it.



Now in that sentence where we are compared with the Japanese 2 things stand out.



1. First is that Australia is by genes racist and there is no denying it. It constantly tries to pass off as a first world nation and tries to come across as a technologically advanced nation which honestly it isn't! Worse in technical innovation, it has fared worse than India when the 200+ years of Australia's history is compared to the 60+ years of Independent India. Let us not go anywhere near comparing pre-independence India with Australia's ancestors who were hunter gatherers as recently as the 4th century when India was at the zenith of its cultural and military might. We will come back to the topic of technological innovations by Australia and post-independence India but first let us examine the roots of why Australia would want to portray India as the economically and technically poor nation. It is not just the Australians alone, even the Brits routinely do it. It is hard for these people to fathom that India in its 60 years of post-independance history would rise among the comity of nations and manufacture everything from the sewing needle to advanced nuclear reactors and aircraft carriers. When India built the nuclear submarine Arihant, British were upset just by the reason that they would keep saying that Britain is technologically more advanced than India because they had built a nuclear submarine but the under water launched missile of the Indians was just a beginning. When Australia portrays India as technologically weak nation and a poor one at that it sort of gives them the first worldly feeling that they so eagerly desire. It also deflects attention from their own pathetic record of technological innovations in their entire history, when I once asked an Australian what they greatest scientific output was he replied that it was the penicillin! I will leave you to read up info on the penicillin and how it was an appropriated invention by an Aussie <img src='http://www.india-forum.com/forums/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='Big Grin' />. Now then you would ask, why do the Australians acknowledge Japan as a major technical power as that would go against our theory after all the Japanese aren't "white" enough. It is a constantly repeated lie in the entire western hemisphere that it was the west that "modernized" Japan and the industrial revolution was brought about in Japan by the West (West being whites by de facto). Now I am not going to go about debunking this absurd and baseless theory, suffice to say that the Japanese were more advanced and civilized way before the Whites got out of their caves and on to town dwellings. Japan is on a leash held by the West. India is not. India has its own sovereignty, the Japs do not. India is to be hated and brought within a leash. The Japanese no longer wish to be the alpha-male, the Indians do as do the Chinese so they are to be hated and a slander campaign started against them with the full might of the powerful Western media.



2. The Australians are in an embarrassing manner, exposing their ignorance of nuclear technology when they say that the Japanese are far advanced while the Indians are not. It has to be readily acknowledged that the Japanese as a technological power has been far advanced to India in the last 150 years. Most of the world's cutting edge comes from Japan but wait it ends there. When it comes to nuclear technology and know-how Indians are at a par with the Japanese and in some cases even ahead of their Buddhist brethren. In fast breeder reactors India pretty much leaves behind all other nations, not the Japanese alone. The Kalpakkam nuclear plant survived the 2004 tsunami without a scratch due to a well thought of positioning for the auxiliary cooling generator whilst the Japanese design gave way. The Australians on the other hand are nowhere in the technological map, for that matter not in nuclear field alone. Till date Australia hasn't had one meaningful innovation of scientific importance which could radically alter the world. Heck, no Australian car brand runs in India whilst 2 Indian car brands and a tractor brand are actively clamouring for market space in Australia. The Australian armed forces are a joke and they cannot even man their navy completely. Whilst India has produced nuclear reactors, human space launchers, dozens of satellites, heavy launch lifters, nuclear submarines, fighter aircraft, aircraft carriers etc etc puny Australia hasn't managed to produce any of these at all. They live on reflected glory off the British and the Americans and so eagerly brand themselves a first world nation when their scientific output is zilch compared to any other decent first world nation. Australian living standards is brought about by 200+ years of conflict free development and India in this same period of comparison would be far ahead of Australia in the same time period. When the Australians froth at their mouth proudly proclaiming this point, when they are reminded of the point I raised they just quieten down and say they are talking of the present! Indeed the Australians would love to dwell in the present as their past isn't much to write home about especially the part on the convict genes. With Indian GDP promising to double every 7-8 years it is not difficult to see that Indian standards of living will reach Australian levels in the next 40-50 years, brought about by 110 years of conflict free development whilst the Australians took more than 150+ years to do the same. Plus the Indians in their 60+ years of post-independence history have developer more cutting edge first world technology than the Australians have!



We rest our case!
