Russian Nuclear Plant Fire.







Russia Nuclear Institute Fire: 'No Threat' Says Government

First Posted: 02/ 5/2012 8:47 am Updated: 02/ 5/2012 3:34 pm



MOSCOW, Feb 5 (Reuters) - A fire broke out on Sunday at a Moscow nuclear research centre that houses a non-operational 60-year-old atomic reactor, an emergency official said, and Russia's nuclear agency said there were no open flames and no threat of a radiation leak.

The environmental group Greenpeace Russia expressed serious concern about the incident.

The fire was in a basement at the Institute of Theoretical and Experimental Physics in southwestern Moscow, said Sergei Vlasov, spokesman for the Moscow branch of the Emergencies Ministry. He said no casualties were reported.

Grey smoke rose above the institute, which is encircled by a wall, and an acrid smell filled the air. Some 30 emergency vehicles, including fire trucks and ambulances, stood inside and outside the main gate, witnesses said.

Sergei Novikov, spokesman for Russia's state nuclear agency Rosatom, said there were no open flames, only smoke that came from an area housing power cables and could not affect any nuclear materials at the institute.

"This case poses no threat to fissile materials," said Novikov, adding that firefighters were pumping foam into the affected area. He said the institute's heavy-water research reactor was no longer operational.

A Greenpeace Russia official said the incident was potentially very dangerous.

"This is extremely dangerous ... this should not have happened at all, but as long as it did, it shows there has been a major failure in their operations," said Ivan Blokov, campaign director at Greenpeace Russia.

"What we have here is a large amount of radioactive substance right in the centre of Moscow and even if a minor quantity leaks, it would pose a serious problem," he said.

Russian news agencies issued conflicting reports.

Interfax cited a police source as saying fire brigades were denied access to the facility for "a long time" before being allowed in.

Vlasov said he could not confirm the report, but said the fire had not been extinguished as of 2:45 p.m. (1045 GMT). State-run RIA reported earlier that that the fire had already been put out.

Safety at Russia's nuclear facilities has been a concern since the deadly 1986 accident at the Chernobyl nuclear power plant in Ukraine, then a Soviet republic. The Soviet authorities did not announce that disaster for two days.

A fire aboard a nuclear submarine in the north Russian port of Murmansk in December severely damaged the vessel, but authorities said radiation levels remained normal.

Fire at Russian Nuclear Research Centre in Moscow



A fire broke out on Sunday at a Moscow nuclear research centre that houses a non-operational 60-year-old atomic reactor, emergency officials reported as Russia’s nuclear agency Rosatom said the blaze had not been accompanied by any open flames and posed no threat of a radiation leak.

While the cause remains undetermined, Sergei Vlasov, a spokesman for the Moscow branch of the Emergency Services ministry, told Reuters that fire has begun in a basement.

Sergei Novikov, a spokesman for Rosatom, remained mum about whether any nuclear or radioactive materials remained in the six-decade old heavy water reactor, though they said the reactor is non-operational.

He said that firefighters were pumping foam into the affected area, and that the institute’s heavy-water research reactor was no longer operational, the Reuters report said.

Grey smoke was reported by witnesses to be rising above the institute, which is encircled by a wall as bitter smell filled the air, Reuters reported.  Interfax cited a police source as saying fire brigades were denied access to the facility for “a long time” before being allowed in.  Some 30 emergency vehicles, including fire trucks and ambulances, stood inside and outside the main gate of the institute, witnesses told the news agency.

Is the U.S. Government Telling Us The Truth About Radiation From Japan?

Do you want to know where the radioactive water from the Fukushima Nuclear facility will spread?... Here is a pretty good idea.

Fukushima Daiichi Radioactive Seawater Model April 5 from ASR Limited on Vimeo.


If you don't think that the government would cover up something as important as radiation in the United States from Japan, think again...


ALERT: Government Cover Up Of This Story Underway
Important! After you read this article, make sure you read this to open your eyes to how the government propaganda machine works.


Despite countless reassurances that no harmful levels of radiation from the Japan nuclear fallout would hit the US from the EPA, the University of Berkley in California is now reporting that rainwater in San Francisco water has now been detected at levels 18,100% above federal drinking water standards.


Radioactive Iodine-131 in Pennsylvania rainwater sample is 3300% above federal drinking water standard.


The Federal Governments also plans to raise the legal limits of acceptable radiation exposure so they can continue to say the amounts of radiation are below levels of concern.





The question is though, if the amounts being detected really present no danger to the public, then why raise the legal levels of acceptable radiation exposure?


Do you worry about radiation? Maybe we should.

Detectable Radiation Could Come To U.S. But Not Likely Significant Concern For Human Health

Posted by: JeffMasters, 2:16 PM GMT on March 16, 2011
If there is going to be a major nuclear disaster with massive release of radioactivity into the atmosphere from Japan's stricken Fukushima nuclear plant, today would be the best day meteorologically for this to occur. The low pressure system that brought rain and several inches of snow to Japan yesterday has moved northeastwards out to sea, and high pressure is building in. The clockwise flow of air around the high pressure system approaching Japan from the southwest is driving strong northwesterly winds of 10 - 20 mph over the region. These winds will continue through Thursday, and will take radiation particles emitted by the stricken reactors immediately out to sea, without lingering over Japan. Since high pressure systems are regions of sinking air, the radiation will stay close to the ocean surface as the air spirals clockwise over the Pacific. The contaminated air will remain over the ocean for at least five days, which is plenty of time for the radiation to settle out to the surface.


Figure 1. Surface weather map for 8am EDT today, taken from the 6-hour forecast from this morning's 6 UTC run of the GFS model. A high pressure system to the southwest of Japan, in combination with a low pressure system to the northeast are driving strong northwesterly surface winds over the country. Image is from our wundermap with the "Model" layer turned on. The lines are sea-level pressure (blue contours, 4 mb interval) and 1000 to 500 mb thickness (yellow contours, 60 m interval). Thickness is a measure of the temperature of the lower atmosphere, and a thickness of 5400 meters is usually close to where the dividing line between rain and snow occurs.

Thursday night and Friday morning (U.S. time), the high pressure system moves over Japan, allowing winds to weaken and potentially grow calm, increasing the danger of radioactivity building up over regions near and to the north of the nuclear plant. On Friday, the high departs and a moist southwesterly flow of air will affect Japan. These southwesterly winds will blow most of the radiation out to sea, away from Tokyo. Southwesterly winds will continue through Sunday, when the next major low pressure system is expected to bring heavy precipitation to the country. Beginning Thursday night, the sinking airmass over Japan will be replaced a large-scale area of rising air, and any radiation emitted late Thursday through Friday will be carried aloft towards Alaska and eastern Russia by this southwesterly flow of rising air.

Ground-level releases of radioactivity are typically not able to be transported long distances in significant quantities, since most of the material settles to the ground a few kilometers from the source. If there is a major explosion with hot gases that shoots radioactivity several hundred meters high, that would increase the chances for long range transport, since now the ground is farther away, and the particles that start settling out will stay in the air longer before encountering the ground. Additionally, winds are stronger away from ground, due to reduced friction and presence of the jet stream aloft. These stronger winds will transport radioactivity greater distances. I've made trajectory plots for the next three days assuming two possible release altitudes--a surface-based release near 10 meters, which should be the predominant altitude in the current situation, and a higher release altitude of 300 meters, which might occur from an explosion and fire from a Chernobyl-style incident. Given that the radioactivity has to travel 3000 miles to reach Anchorage, Alaska, and 5000 miles to reach California, a very large amount of dilution will occur, along with potential loss due to rain-out. Any radiation at current levels of emission that might reach these places may not even be detectable, much less be a threat to human health. A Chernobyl-level disaster in Japan would certainly be able to produce detectable levels of radiation over North America, but I strongly doubt it would be a significant concern for human health. The Chernobyl disaster only caused dangerous human health impacts within a few hundred miles of the disaster site, and the distance from Japan to North America is ten times farther than that.
