Jellyfish Cause Shutdown At Massive Swedish Nuclear Power Plant

jelly

The New York Times reports on how the world ends:

In an episode that evokes B-grade sci-fi movie plots, but actually reflects a continuing global problem, nuclear engineers in Sweden have been wrestling with a giant swarm of jellyfish that forced the shutdown of the world’s largest boiling-water reactor.

The plant’s operator said that a huge cluster of moon jellyfish clogged the cooling water intake pipes at the Oskarshamn nuclear power plant on the Baltic Sea coast, forcing the complex’s 1,400-megawatt Unit 3 to shut down.

Nuclear power plants are often placed next to large bodies of water, so jellyfish clogs are a recurring problem. The plant had a similar episode in 2005.

The Oskarshamn nuclear power plant uses the same technology employed at Japan’s Fukushima Daiichi nuclear complex, where a powerful earthquake and tsunami in 2011 caused the worst nuclear disaster since Chernobyl.

Nuclear Reactor At Fukushima May Turned Into A Tourist Attraction

dark tourismA summer vacation spot that will give you a healthy glow? Thanks to a tip from Rhoid – Japan Today reports:

Paying visits to historic places where death and suffering occurred is known as “dark tourism.” After taking note that in 2011, or 25 years after the accident, the Chernobyl reactor site has become open to general tourism, a group of individuals in Japan is attempting to lay the groundwork for plans to make the No. 1 reactor at the stricken Fukushima Daiichi nuclear power plant a tourist spot.

The group includes author-critic Hiroki Azuma, tourism scholar Akira Ide, artist Kazuki Umezawa, media activist Daisuke Tsuda, sociologist Hiroshi Akenuma, editor Kenro Hayami and architect Ryuji Fujiwara.

Along with providing a venue to convey their own histories to future generations, the members aim for the activities to be useful in aiding in recovery of the affected areas.

Japanese Authorities Admit Fukushima Has Been Leaking Radiation Into Water For Two Years, And Cannot Be Stopped

fukushimaVia the New York Times, a reminder to always take officials with a grain of salt when they issue statements denying that the oceans and air are being poisoned:

The stricken nuclear power plant at Fukushima has probably been leaking contaminated water into the ocean for two years, ever since an earthquake and tsunami badly damaged the plant, Japan’s chief nuclear regulator said on Wednesday.

In unusually candid comments, Shunichi Tanaka, the head of the Nuclear Regulation Authority, also said that neither his staff nor the plant’s operator knew exactly where the leaks were coming from, or how to stop them.

The operator, Tokyo Electric Power, has reported spikes in the amounts of radioactive cesium, tritium and strontium detected in groundwater at the plant, adding urgency to the task of sealing any leaks. Radioactive cesium and strontium, especially, are known to raise risks of cancer in humans.

Until recently, Tokyo Electric, known as Tepco, flatly denied that any of that water was leaking into the ocean, even though various independent studies of radiation levels in the nearby ocean have suggested otherwise.

Radioactive Goldfish Discovered At Ohio Nuclear Power Plant

radioactive goldfish

No word on an eye count. Russia Today reports:

Two radioactive goldfish were found swimming in a juice pitcher of nuclear reactor water in an underground steam tunnel at an Ohio power plant. Investigators are baffled as to how the radioactive fish remained unnoticed in the ‘secure’ facility.

Investigators from the Nuclear Regulatory Commission and officials of the plant, which is operated by FirstEnergy Corp., have been looking through surveillance tapes to try to identify who was responsible for leaving the radioactive goldfish in the tunnel on May 2.

The fishy tale has served as an embarrassment for the plant, which has already come under scrutiny for a case in which four contractors were exposed to life-threatening hard radiation in 2011. The plant has also been scutinized for a serious lack of security.

Unraveling The Stuxnet Virus

From Patrick Clair a year ago, a quick and excellent look at the troubling Stuxnet virus. It has since been confirmed that the United States and Israel were behind its use against Iran's nuclear facilities. The question is now, what have we unleashed?
An infographic dissecting the nature and ramifications of Stuxnet, the first weapon made entirely out of code. This was produced for Australian TV program HungryBeat.

Confessions Of A Nuclear Power Safety Expert

3464115270_3c602de1d8An expert on the safety of nuclear power plants comes to the conclusion that there is simply no such thing as an 100 percent safe nuclear reactor. Via Miller-McCune:

I soon came to the conclusion that neither international cooperation nor technological advancements would guarantee human societies to build and safely run nuclear reactors in all possible conditions on Earth (earthquakes, floods, droughts, tornadoes, wars, terrorism, climate change, tsunamis, pandemics, etc.). I am sadly reminded of this turning point in my life as I listen to the news about the earthquake, tsunami and extremely worrying nuclear crisis in Japan.

When Italy decided in the mid-’70s to add nuclear power to its power portfolio, young mechanical and nuclear engineer Cesare Silvi was among those attracted to the opportunities it presented. His work centered on nuclear safety issues — in particular, what might happen if something unexpected struck a power plant.

Corners he saw cut there eventually soured Silvi on that endeavor.

Japanese Engineers Plug Fukushima Leak

This sounds familiar, did they get advice from BP? The Guardian reports:

Engineers battling to contain the crisis at Japan‘s Fukushima nuclear power plant appeared to have turned an important corner last night after they stopped highly radioactive water from leaking into the ocean from one of the facility’s crippled reactors.

Workers struggling to halt the leaks successfully used a mixture of sawdust, newspaper, concrete and a type of liquid glass to stem the flow of contaminated water near a seaside pit, said the plant’s owner, Tokyo Electric Power Co (Tepco).

Earlier efforts involving cement, an absorbent polymer and rags were unsuccessful in plugging the leak, which was discovered on Saturday, while radiation of more than 7.5 million times the legal limit for seawater was found just off the earthquake-hit plant.

In a sign of Tepco’s desperation, it breached its own regulations on Monday by beginning an intentional discharge of 11,500 tonnes of less contaminated water into the Pacific to make space for the highly radioactive liquid that was seeping out in an uncontrolled manner.

America’s Most Vulnerable Nuclear Power Plants

3596889720_f52826d665_zIs this list a case of fear-mongering? Possibly, but I would want to be aware if I lived nearby one of these wildcards. The Daily Beast presents a ranking of our nation's most ripe-for-disaster nuclear reactors, as determined by a panel of experts, with Indian Point (Buchanan, NY), San Onofre ( San Clemente, CA), and Limerick, PA rounding out the top three:
1. Indian Point Location: Buchanan, NY (24 miles north of New York City) Reactors: 2 Electrical Output (megawatts): Unit 2: 1020; Unit 3: 1025 Year Operating License Issued: Unit 2: 1973; Unit 3: 1975 Population within 50 Miles: 17,452,585 Relative Safety Rating: bottom third

Many citizens across Asia have been warned about faux messages being sent, such as this e-mail: “Japan Government confirms radiation leak at Fukushima nuclear plants. Asian countries should take necessary precautions. If rain comes, remain indoors first 24 hours. Close doors and windows. Swab neck skin with betadine where thyroid area is, radiation hits thyroid first. Take extra precautions. Radiation may hit Philippine at around 4 pm today. If it rains today or in the next few days in Hong Kong. Do not go under the rain. If you get caught out, use an umbrella or raincoat, even if it is only a drizzle. Radioactive particles, which may cause burns, alopecia or even cancer, may be in the rain.” BBC reports:

A fake text message warning people that radiation from the Fukushima nuclear plant has leaked beyond Japan has been panicking people across Asia.
