Hydrogen Building Up at Reactor 1, Fukushima NPP

UPDATED at 13:00UTC

Will the Scope of Fukushima Nuclear Disaster Widen?

Based on the information available, FIRE-EARTH believes there’s a strong probability that the extent of Fukushima nuclear disaster could widen to directly impact large population centers in Japan up to a 250 – 300km radius of the plant, which includes Tokyo Metropolitan Area.

The reactor vessel or sections of its attachments in one or more of the severely damaged reactors at the plant could explode releasing humongous amounts of radiation into the environment [Probability ≥66% as of posting,] dwarfing the Chernobyl disaster by a massive factor.

Hydrogen gas may be accumulating in Reactor 1 at Fukushima NPP: TEPCO

Tokyo Electric Power Company (TEPCO) said it may have to inject nitrogen gas into Reactor 1 at the stricken Fukushima NPP to prevent a possible explosion from hydrogen buildup, NHK reported.

According to another report, TEPCO is preparing to also pump nitrogen into Reactors 2 and 3.

Buildup of hydrogen gas in three of the reactors at Fukushima NPP caused several explosions following the Great Eastern Japan Earthquake and tsunami which crippled the plant on March 11.

Injection of nitrogen gas is meant to dilute the amount of oxygen and hydrogen gasses and prevent them from reaching critical concentration levels, 5 and 4 percent respectively, at which an explosion occurs. 

Meanwhile TEPCO announced that it had stopped the flow of highly radioactive water into the ocean from a cracked concrete duct near Reactor No. 2 , using a sodium-silicate compound as a sealant.

Remembering Chernobyl Victims

All is NOT Well at Chernobyl

Chernobyl Spin Nuked

Anyone who tells you animal populations are rebounding around the the Chernobyl, all is well at the site of the Ukrainian nuclear power plant which underwent a meltdown in 1986, and that nuclear energy is green and safe, is either a pathological liar, or has a personal stake in the industry. FEWW

Chernobyl animals worse affected than thought: study

LONDON (Reuters) – Radiation has affected animals living near the site of Ukraine’s Chernobyl nuclear disaster far more than was previously thought, a study showed Wednesday, challenging beliefs that local wildlife was on the rebound.

The study showed that numbers of bumble-bees, butterflies, spiders, grasshoppers and other invertebrates were lower in contaminated sites than other areas because of high levels of radiation left over from the blast more than 20 years ago.

The findings challenge earlier research that suggested animal populations were rebounding around the site of the Chernobyl explosion in Ukraine, which forced thousands to abandon their homes and evacuate the area.

Ukraine’s Chernobyl nuclear power plant underwent a core meltdown [center] in 1986 with disastrous consequences. This image was taken by authorities in the former Soviet Union.

Estimates of the number of deaths directly related to the accident vary. The World Health Organization estimates the figure at 9,000 while the environmental group Greenpeace predicts an eventual death toll of 93,000.

“We were amazed to see that there had been no studies on this subject,” Anders Moller, a researcher at the National Center for Scientific Research in France, who led the study, said in telephone interview.

“Ours was the first study to focus on the abundance of animal populations.”

Researchers said they had compared animal populations in radioactive areas with less contaminated plots and found that some were nearly completed depleted of animal life.

“There are areas with an abundance of 100 animals per square meter,” Moller said. “And then there are areas with less than one specimen per square meter on average; the same goes for all groups of species.”

The researchers also found that animals living near the Chernobyl reactor — which was covered in a protective shell after it exploded in April 1986 — had more deformities, including discoloration and stunted limbs, than normal.

“Usually (deformed) animals get eaten quickly, as it’s hard to escape if your wings are not the same length,” Moller said. “In this case we found a high incidence of deformed animals.”

The findings challenge the view of Chernobyl as ecologically sound, despite the fact that Ukrainian officials have turned it into a nature reserve, with wolves, bison and bears.

Earlier research into the area ignored the fact that animal populations had grown unimpeded in the absence of humans for many years after the blast, Moller said.

“We wanted to ask the question: Are there more or fewer animals in the contaminated areas? Clearly there were fewer,” said Moller, who has worked on Chernobyl since 1991.

While researchers focused on the 30 kilometer radius around the Chernobyl reactor, the fallout from the explosion covered a vast swathe of Eastern Europe, including parts of Russia, Ukraine and Belarus.

The findings probably apply to those areas as well, Moller said, adding that any decontamination effort was unlikely due to the extent of the fallout. Copyright Reuters.
