Nuclear Power Plant Reactor in Gyeongju Shuts Down

OCT 30, 2012

A nuclear power generator at the Wolseong Nuclear Power Plant in Korea’s southeastern city of Gyeongju automatically shut down on Monday evening.
The state-run operator, Korea Hydro & Nuclear Power, says Reactor number 1 stopped generating at around 9:40PM after a turbine stop signal. 
No radiation leak has been reported.
The operator says it is looking into the exact cause of the shutdown, but added the nuclear reactor is in a safe condition.
The reactor has been operational since 1983,and its 30-year life span is scheduled to end next month.

IAEA team tours Indian nuclear plant after radiation leak

” A report by India’s auditor-general has found serious problems with safety regulations within India’s nuclear facilities. Australia has just agreed to supply uranium to India.”

“But environmental watchdogs have expressed concerns about safety in India, where small-scale industrial accidents due to negligence or poor maintenance are commonplace and regulatory bodies are often understaffed and underfunded”2

* Inspectors will examine working practices, safety procedures as well as condition of equipment

JAIPUR: A team from the UN’s nuclear watchdog began a safety inspection on Monday at a power plant in northern India where dozens of workers were exposed to radiation in separate leaks earlier this year.

The inspectors were touring the Rajasthan Atomic Power Station to “review the programmes and activities essential to plant operation based on the IAEA safety standards and on proven good practices”, said a statement by the watchdog.

UK-Nick Clegg warns Philip Hammond over Trident nuclear missile plan -Telegraph

“In the meantime, we are pressing ahead with the design and development work,” Mr Hammond said.

Nick Clegg has accused Philip Hammond of “jumping the gun” on plans to build a new generation of nuclear-armed submarines.

By , Political Correspondent

2:35PM GMT 29 Oct 2012


Mr Hammond, the Defence Secretary, announced £350 million to design a replacement to the Trident missile programme in what he claimed was a demonstration of the government’s “very clear” commitment to Britain’s nuclear deterrent.

However, the Deputy Prime Minister warned that the Tories had promised there would be no decision on whether to build a new generation of submarines to carry nuclear weapons until 2016.

The Liberal Democrats have launched a government review into whether a “credible” alternative plan could provide a nuclear deterrent at a lower cost than the estimated £20 billion bill for a new submarine capability.[…]

Mr Clegg dismissed the idea of simply ordering a new fleet of nuclear-armed submarines as outdated and expensive.

“The idea of a like-for-like, entirely unchanged replacement of Trident is basically saying we will spend billions and billions and billions of pounds on a nuclear missile system designed with the sole strategic purpose of flattening Moscow at the press of a button,” he said. “I think some people are jumping the gun on this Trident decision.

UPDATE- Salem and Hope Creek reactors likely to shut -Reactors in Pennsylvania and Maryland could shut

Mon Oct 29, 2012 3:45pm GMT


PJM is the biggest power grid in the United States serving
more than 60 million people in 13 U.S. Mid-Atlantic and Midwest
states and the District of Columbia

UPDATE 1-Sandy likely to shut at least two NJ nuclear reactors

* PSEG Salem and Hope Creek reactors likely to shut
    * Reactors in Pennsylvania and Maryland could shut

    By Scott DiSavino
    Oct 29 (Reuters) - At least two major New Jersey nuclear
power plants are likely to shut o n M onday as Hurricane Sandy
makes landfall as a Category 1 storm, and more plants could
reduce power as the storm triggers precautionary safety
    Sandy, centered over the Atlantic Ocean about 310 miles (505
km) southeast of New York City, was expected to hit near
Delaware and south New Jersey in about 12 hours as a Category 1
hurricane with winds of up to 90 miles per hour (144 kph).
    The nuclear reactors in Sandy's current path include units
at Public Service Enterprise Group Inc's 2,332-megawatt
(MW) Salem and 1,161-MW Hope Creek plants in New Jersey, which
were likely to bear the brunt of the storm before it moves
inland. Those plants combined would account for about 19 percent
of the state's total electricity capacity, although New Jersey
also draws supplies from the whole Pennsylvania, New Jersey,
Maryland (PJM) power region.
    PJM is the biggest power grid in the United States serving
more than 60 million people in 13 U.S. Mid-Atlantic and Midwest
states and the District of Columbia.
    Electricity traders said if Sandy continues on her expected
path it was likely PSEG would have to shut the Salem and Hope
Creek reactors later Monday, but they were mixed on whether the
storm's winds would still be strong enough to force the shutdown
reactors in Pennsylvania and Maryland.
   PSEG spokesman Joe Delmar said the company would take the
Salem and Hope Creek reactors offline if wind speeds reach
greater than 74 miles per hour (119 kph) onsite for more than 15
minutes or the river water level reaches 100 feet (30 meters).
Sandy's maximum winds were at 85 mph (136 kph) earlier on

Lingering radiation around Mount Akagiyama in northern Maebashi =2 year ban on fish

“Hato Bus Co., which used to organize tours to the lake every year, plans no such visits this autumn because of the ban on taking the smelt home. Furthermore, elementary and junior high schools have canceled student trips.”

October 29, 2012

Asahi Shimun 


Akagi Onuma, a caldera lake atop Mount Akagiyama in northern Maebashi, usually attracts 25,000 tourists to fish for freshwater smelt during a seven-month season starting in September.

But visitor numbers to the area in Gunma Prefecture have fallen by 90 percent compared with levels prior to the March 2011 disaster at the Fukushima No. 1 nuclear power plant. This autumn, about 100 boats lie idle along the shore. On autumnal weekends in the past, all boats would have been rented out.

“Revenue has almost dried up since the earthquake,” said Takeshi Aoki, 48, a manager at Aoki Ryokan, a lakeside inn.

USA: nuclear reactors – assurances of safety precautions

 they are unlikely to be affected by strong winds or unusually high tides.

Hurricane Sandy and N.J. nuclear power plants: Keeping it cool in high
winds , 28 OCTOBER 2012   BY ROBERT KINKEAD On Sunday, New Jersey’s four nuclear power stations, along with another dozen or so along the Eastern Seaboard,were prepped to deal with Hurricane Sandy as that massive storm crawls up the East Coast toward the Garden State.

Federal regulators require nuclear reactors to be in a safe shutdown condition at least two hours before hurricane force winds strike, according to Alec Marion, VP of nuclear operations at the Nuclear Energy Institute, an energy industry association.

Typically, plant operators begin shutting down reactors about 12 hours before winds exceeding 74 miles per hour arrive. One of the most significant challenges in the shutting down process is keeping the reactor core cool. Continue reading

AUDIO: Hazards of power loss, in nuclear reactors’ shutdown

Gundersen: 26 nuclear plants in area where Hurricane Sandy likely to hit — If power lost, only plan is to let spent fuel pools heat up… no generators to pump in water (AUDIO) October 28th, 2012

Transcript Summary of an excerpt from the October 28, 2012 podcast by Fairewinds Energy Education:

You’ll hear in the next 2 days, “We’ve safely shutdown the plant”
What Fukushima taught us is that doesn’t stop the decay heat
You need the diesels to keep the reactors cool
26 plants in the East Coast are in the area where Sandy is likely to hit
Fuel pools not cooled by diesels, no one wanted to buy them
If recent refuel, hot fuel will throw off more and more moisture from pool
Reactor buildings not meant to handle the high humidity
Fuel pool liner not really designed to approach boiling water, may unzip if water gets too hot
A lot of problems with allowing fuel pool to over
Need water in around 2 days if hot fuel in pool
The only fall-back if power is lost is to let fuel pools heat up

More than a Dozen Nuclear Plants Near Hurricane Sandy’s Path Brace for Impact

Page added on October 27, 2012

Bloomberg reports:

“Because of the size of [Hurricane Sandy], we could see an impact to coastal and inland plants,” Neil Sheehan, a spokesman based in Philadelphia for the U.S. Nuclear Regulatory Commission, said by phone today. “We will station inspectors at the sites if we know they could be directly impacted.”

The NRC met earlier today to discuss the necessary precautions to take for the storm, Sheehan said. Plants must begin to shut if wind speeds exceed certain limits, he said.

As of 2 p.m. New York time, Sandy had winds of 75 miles (121 kilometers) per hour, according to the National Hurricane Center in Miami. It was about 430 miles south-southeast of Charleston, South Carolina, moving north at 7 mph.

The current Hurricane Center track calls for the system to come ashore just south of Delaware Bay on Oct. 30.

Reuters provides a list:

The following lists the nuclear reactors and utilities in Sandy’s potential path.

New earthquake data for Tokyo and its not good for nuclear

Tokyo prepares for the ‘Big One’

NATIONAL OCT. 29, 2012

“In the past five years, nearly 300 seismographs have been installed in Tokyo schools at a cost of over 1.0 billion yen, transmitting data to a central authority.

But the plan has also revealed worrying subterranean activity: fault lines far shallower than previously thought.

“It was a great shock to me,” said Sakai at Tokyo’s quake research institute, as he stared as his seismograph-connected laptop. “It’s constantly moving down there.””


Concern about the so-called “Big One” spiked again over the summer when the government unveiled a worst-case disaster scenario that estimated 323,000 people would die if a 9.0 magnitude unleashed a 34-meter tsunami along the coastline south of Tokyo.

City officials said it was intended to encourage improvements in quake warning systems, evacuation planning and disaster reduction.


Sahara added that the association has ramped up efforts to keep track of its residents, especially the elderly.

“After March 11, we made a list of old people in the district, especially those living alone. There is a sense of solidarity here,” Sahara said.

As Japan become better prepared for the inevitable disaster, new knowledge also brings new uncertainty.

Nuclear energy preparing for retirements, growth

U.S. aims to broaden its electricity sources while curbing emissions and an impending glut of retirement-eligible workers promise major changes in the nuclear induustry work force.

The Nuclear Energy Institute says 39 percent of the country’s nuclear-industry workers will reach retirement age by 2016, which could lead to a significant loss of experience and knowledge of how to safely use nuclear power — an issue that has great import in the wake of last year’s earthquake and tsunami that battered a reactor in Japan.

Nuclear Fallout – Map of U.S. Nuclear Power Plants dispertion projections – Super storm in USA

There are 104 nuclear reactors in the United States. If one of them lost both primary and backup power for even a matter of hours, it could lead to a meltdown and an airborne radioactive plume. See what could have happened if a reactor in your area had a severe nuclear accident on March 11, 2011.

  • Threshold for Radiation Sickness (75 rads)*
  • Maximum Radiation Dose Recommended for Emergency Responders (25 rads)*
  • Evacuation Recommended (5 rads)*
  • Sheltering Recommended (1 rad)*
  • 10-mile Evacuation Zone
  • 50-mile Potential Contamination Zone

* Acute radiation dose based on 48 hour exposure, assuming no sheltering. Sheltering can reduce radiation dose by a factor of ten or more.

Why U.S. nuclear power plants are vulnerable to severe accident with nuclear fallout

A future severe nuclear accident at a U.S. nuclear power plant is a real possibility. In 2011 five nuclear power plants in the United States lost primary power due to earthquake or extreme weather events, including tornados, hurricanes, and flooding. Fortunately backup power systems kicked in at these plants and a disaster was averted. But weather is not the only risk factor. Other risk factors include:

  • Type of reactor – There are two types of reactors operating it the United States: Boiling Water Reactors (BWRs) and Pressurized Water Reactors (PWRs). Some experts judge that the design and structure of BWRs do not protect against the release of radiation during a severe accident as effectively as PWRs. The four reactors involved in the Fukushima nuclear crisis were BWRs. On the map, NRDC experts assigned a red flag to a reactor if it is a BWR.
  • Age of reactor – Reactors were designed to operate for 40 years, yet the regulatory body that oversees nuclear safety in the United States, the Nuclear Regulatory Commission, has re-licensed some nuclear power plants to operate for 60 years, well beyond their originally engineered design lifetime. On the map, NRDC experts assigned a red flag to a reactor if the NRC has approved the reactor to operate for 60 years.
  • Power level of reactor – The NRC has approved many utility operators to increase the operating power of their nuclear reactors, including for Fukushima-type reactors, and in some cases multiple times and to significantly higher power levels. These so-called “power uprates” push reactors beyond what they were originally engineered to do, and could increase the radiation hazard if a nuclear accident occurred. On the map, NRDC experts assigned a red flag if the NRC has granted a reactor a power uprate.

If a person received one rad of radiation from a nuclear accident, it would increase one’s chance of getting cancer by 1 in 1,000 (averaged over all ages and both sexes). And although the NRC believes that the chances of a severe accident with fallout in a core meltdown for any one of the 104 U.S. nuclear reactors is small (probability of less than 1 in 10,000 per year), can we afford the risk? Millions of Japanese people were exposed to radiation from Fukushima, increasing their risk of developing cancer, and the cost of the Fukushima accident is projected to exceed US$100 billion, and the environmental effects will last for generations. What if a meltdown occurred at one of the 65 nuclear power plants in the United States?

Why we need urgent federal action to reduce the risks of U.S. nuclear accident fallout

With 6 million Americans living within 10 miles of a U.S. nuclear power plant – the evacuation zone defined by the federal government – and more than 120 million Americans living within 50 miles of a U.S. nuclear power plant – the distance the U.S. government told Americans to evacuate from the area around the Fukushima plant – we cannot afford to stand by and hope the worst won’t happen here, especially with extreme weather intensifying around the globe.

Admission of “dangerously high doses” to Fukushima workers -need to develop robots -Audio and Video

A Contest To Build A Disaster-Ready Robot

October 26, 2012

When disasters hit, relief workers often have to put their own lives at risk. Many workers at the Fukushima nuclear reactor in Japan received dangerous doses of radiation after the accident there last year. The Pentagon hopes a contest to build a better robot will make it easier and safer to mitigate disasters.

Immediately after the tsunami and explosions that damaged the Fukushima plant, workers had no way to access areas where radiation levels were lethal. Robots from Massachusetts-based iRobot had to be rushed in. iRobot CEO Colin Angle says valuable time was lost as personnel were trained how to use them.

“Robots on site would have saved days. Appropriate training would have saved days and potentially could have minimized the venting of some of the radioactive gasses,” Angle says.

That’s why DARPA, the Defense Advanced Research Projects Agency, this week launched a “Robotics Challenge,” to encourage the development of robots that anyone can use.

An unnamed robot that the Carnegie Mellon National Robotics Engineering Center plans to build for the DARPA Robotics Challenge.

A Robot The Size Of A 10-Year-Old Boy

Seven hardware teams announced this week will compete for a $2 million prize. Among the robot competitors is an entry called “Hubo.”

Professor Paul Oh, who leads the Drexel University team that built Hubo, says the robot is about 4-feet-3 inches tall — about the size of a 10-year-old boy.

This week, Drexel and the other teams learned some of the challenges Hubo will face in a junkyard-wars-style competition next year. The robots will have to open a blocked door, operate a valve, climb a ladder. And perhaps the toughest: get into and drive a vehicle.

Oh says when we drive, we rely on lots of sensations. When you hit an obstacle, you can feel it with your wheel, and you can hear it.

“These are all perceptual challenges that we have to teach our robot,” he says.

Oh and the other researchers have until next year to teach their robots these tasks. During the actual challenge, DARPA folks will be throwing a lot of curves at the competitors, like messing with their communications. You’d expect a lot of radio interference if you were working in a damaged nuclear reactor or in a collapsed building after a terror attack.

Nuclear war prevented by one thoughtful Soviet officer

The launch of the B-59′s nuclear torpedo required the consent of all three senior officers aboard. Arkhipov was alone in refusing permission.

Thank you Vasili Arkhipov, the man who stopped nuclear war Fifty years ago, Arkhipov, a senior officer on the Soviet B-59 submarine, refused permission to launch its nuclear torpedo Edward Wilson,  27 October 2012  If you were born before 27 October 1962, Vasili Alexandrovich Arkhipov saved your life. It was the most dangerous day in history. An American spy plane had been shot down over Cuba while another U2 had got lost and strayed into Soviet airspace. As these dramas ratcheted tensions beyond breaking point, an American destroyer, the USS Beale, began to drop depth charges on the B-59, a Soviet submarine armed with a nuclear weapon.

Hurricane and storm surge risks to nuclear reactors

Weather Channel Hurricane Specialist: “All hell is breaking loose”— “  Sandy already one of biggest on record
October 28th, 2012
Watch the most current satellite loop from NOAA here

Title: Sandy on Track – But Is the Message Getting Out?
Source: Bryan Norcross, Hurricane Specialist at The Weather Channel
Date: Oct 28, 2012

Hurricane Sandy (Source: NBC)
Sandy the super-unusual, combo hurricane/nor’easter on the unheard-of track is coming together as forecast.

[…] the focus on that energy is going to be on North Jersey, New York Harbor, and the south shore of Long Island. The National Weather Service in New York is predicting waves 10 to 20 feet high on the south-facing beaches. Holy crap!

Did I also mention that’s on top of the storm surge, which is forecast to raise the ocean level 4 to 8 feet above normal? And did I also mention that there’s a full moon and the storm’s peak is expected to be around high tide? Holy triple whammy!

National Hurricane Center Forecast, 11p ET, Oct. 27, 2012
[…] the National Weather Service decided NOT to issue a Hurricane Watch for the Northeast coastline… are you ready for this… because it would be confusing to switch from that to a Coastal Flood Watch and a High Wind Watch after the storm – which will come ashore with hurricane-force winds – morphs into another kind of storm according to the meteorology dictionary. […]

I grant that a technical reading of the “rules” says that you can’t put up a Hurricane Watch and a Coastal Flood Watch and a High Wind Watch at the same time. But I’m betting the rules didn’t envision a super-mega-combo freak of a storm slamming into the most populated part of the country. When all hell is breaking loose, sometimes you’ve got to break a few rules to do the right thing. […]

The Oyster Creek nuclear power plant near Tom’s River, NJ appears to be at greatest risk for storm surge, as it’s located near the shoreline where the eye of the hurricane is expected to make landfall.
