Nuclear Regulatory Commission Chairman warns on safety factors for Vogtle new nuclear plant
Southern’s `Monumental Accomplishment’ Tempered by Fukushima, Bloomberg, By Brian Wingfield – Feb 9, 2012 The chief regulator’s dissent in a vote that approved the first U.S. permit in 34 years to build a nuclear reactor is fueling a debate over safety as the first anniversary of Japan’s nuclear disaster nears.
The U.S. Nuclear Regulatory Commission voted 4-1 yesterday to award Southern Co. (SO) of Atlanta a license to build two reactors at its Vogtle plant near Augusta, Georgia. The agency should have required the company to implement lessons from Japan’s nuclear crisis last year, said Chairman Gregory Jaczko, who opposed the license.
“Right now we know there are things that need to be fixed, things that need to be changed, or at least things that need to be analyzed,” Jaczko said yesterday in an interview at NRC headquarters in Rockville, Maryland. “For us to issue this license, and say ‘we’ll deal with them later,’ to me is kind of putting the cart before the horse.” Read more »
Fukushima nuclear disaster is an ongoing emeergency
Harvey Wasserman, 10 Feb 12, … the biggest shock waves this week were caused by Tama University Professor Hiroshi Tasaka, a key advisor to Prime Minister Naoto Kan during the Fukushima disaster.
Warning that Fukushima is “far from over,” Tasaka said official assurances of the complex’s alleged safety were based on “groundless
optimism.” Tasaka cited more than 1500 fuel rods dangerously exposed to the open atmosphere at Unit Four alone. The waste problem has gone nationwide, he said in a newly published book, as “the storage capacities of the spent fuel pools at the nation’s nuclear power
plants are reaching their limits,”
Tasaka’s statements came as a new temperature spike unexpectedly stuck Fukushina Unit Two. For reasons not yet clear, heat releases in excess of 158 degrees Farenheit spewed from the core, prompting Tokyo Electric to pump in more water and boric acid meant to damp down an apparently on-going chain reaction. Prof. Tasaka and others warn that this in turn will contribute to spreading still more radiation into the water table and oceans.
With bitter debate raging in Japan, the US and elsewhere over the killing power of Fukushima’s emissions, the certification of a new US
reactor design may someday be remembered as a bizarre epitaph for the 20th century’s most expensive failed technology.
Without state ratepayers and federal taxpayers being forced to foot the bill, new reactor construction in the US is going nowhere.
And without a final resolution to the on-going horrors at Fukushima, the entire planet, from Tokyo to Alaska to Georgia and beyond, remains at serious radioactive risk.

13.5 tons of water hourly in effort to cool Fukushima nuclear reactor No. 2
Boric acid to prevent recriticality, Japan Times,8 Feb 12, Reactor No. 2 heats up, gets more water Kyodo Workers at the Fukushima No. 1 nuclear plant increased the amount of water injected into reactor 2 on Tuesday to the highest level since the plant achieved cold shutdown in December as concerns grew over rising temperatures at the bottom of the pressure vessel….
Tepco said it increased the amount of injected water, some of which contained boric acid, at 4:24 a.m. Tuesday. Reactor 2 is now being cooled with 13.5 tons of water per hour, up from 10.5 tons. The boric acid is being used to prevent a sustained nuclear chain reaction, or recriticality.
Nuclear disaster minister Goshi Hosono told reporters that Tepco is
making every effort to lower the temperature…. http://www.japantimes.co.jp/text/nn20120207x1.html

Level 2 nuclear incidents in France
France declares level 2 nuclear event at Cattenom Feb 6, 2012
* Reactors not shut down after the fault was found
* EDF given 10 days on Jan. 24 to make repairs
* There were four level two events in 2011
PARIS, Feb 6 (Reuters) – France’s nuclear safety authority (ASN) said on Monday it had identified a problem with water pipes at one of EDF’s nuclear plants and rated it a level two event out of a maximum seven on the international nuclear event scale (INES).
Level two ratings occur relatively rarely, but the watchdog said there was no impact on plant workers or the environment from the event. In 2011, the ASN gave four incidents a level two rating. Japan’s Fukushima disaster was rated a level seven event.
Pipes used to pump water into fuel rod cooling pools at reactors 2 and 3 at EDF’s Cattenom nuclear plant were not equipped with a mechanism to prevent them from accidentally pumping water out of the basins.
In case water levels fall in rod cooling pools, the exposed fuel would heat up and release dangerous radioactive material. ”Due to the potential consequences, this event was placed on a level 2 of the INES scale,” the watchdog said in a statement….. http://www.reuters.com/article/2012/02/06/france-nuclear-ines-idUSL5E8D63C120120206
Close to Iran’s nuclear reactor – an earthquake strikes
Earthquake strikes near Iranian nuclear power plant, February 5, 2012. PennEnergy, By Brien Southward An earthquake, measured at 5 on the Richter scale by the US Geological Survey, was felt only 70km from Iran’s Bushehr nuclear power plant, which is expected to go online on March 20. As of 9:46am CST on February 5, 2012, there has been no report yet of casualties or damage at the reactor facility. If damage did occur, it could have consequences for the future of Iran’s nuclear ambitions.
The quake strikes as Iran is mired in a diplomatic crisis with the West overthe ambitions of its nuclear energy program. Iran claims that their research is only for the sake of producing nuclear power to meet the growing energy needs of the developing country of some 74 million people, but numerous world leaders and global organizations such as theUN-affiliated International Atomic Energy Agency are concerned that they could be secretly using nuclear enrichment technology to develop nuclear weapons….. The most recent earthquake, measured at 5.5 on the Richter scale, was felt on January 19 near the city of Neyshabour in northeast Iran, injuring 100 people and causing some structural damage. Iran’s deadliest earthquake struck the northern provinces of Gilan and Zanjan, killing around 37,000 people and injuring more than 100,000. http://www.pennenergy.com/index/power/display/8633237470/articles/pennenergy/power/nuclear/2012/february/quake-strikes_near.html

Nuclear Regulatory Commission orders reassessment of earthquake and flood risks
Nuclear plants told to reassess earthquake risks, Feb 05, 2012 WRCB TV, By Pam Sohn, Chattanooga Times Free Press , The Nuclear Regulatory Commission last week told TVA and other nuclear plant operators to reassess the earthquake risks at each of their reactors.
Initial reviews by NRC and the nuclear industry indicate there are increased risks at some plants, including Sequoyah near Soddy-Daisy and 17 miles north of Chattanooga.
The news comes during the same week NRC told the Tennessee Valley Authority that the sand baskets on three dams above Sequoyah could fail during a massive flood, putting the nuclear plant and its diesel generators at risk.
The baskets were placed along the top and side edges of Cherokee, Fort Loudon, Tellico and Watts Bar dams in 2008 when TVA discovered problems with flood calculations. The data TVA used for its calculations was decades old and outdated, agency officials said.

Wear and tear problem on tubes carrying radioactive water
According to the Nuclear Regulatory Commission, more than a third of the wall had been worn away in two tubes at Unit 2, which will require them to be plugged and taken out of service. At least 20 percent of the tube wall was worn away in 69 other tubes, and in more than 800, the thinning was at least 10 percent.
Inspectors find ‘unusual’ wear on new tubes carrying radioactive water at Calif. nuclear plant Washington Post, By Associated Press, : February 2 LOS ANGELES — Unusual wear has been found on hundreds of tubes that carry radioactive water at Southern California’s San Onofre Unit 2 nuclear plant, raising questions about the integrity of equipment the company installed in a multimillion-dollar makeover in 2009.
The disclosure came two days after a tube leak at the plant’s other unit prompted operators to shut down the reactor as a precaution. The problems at Unit 2 were discovered during inspections of a steam generator, after the plant 45 miles north of San Diego was taken off-line for maintenance and refueling. The two huge steam generators at Unit 2, each containing 9,700 tubes, were replaced in fall 2009, and a year later in its twin plant, Unit 3, as part of a $670 million overhaul. Read more »
Indian Point nuclear plant was refused exemptions from fire safety regulations
NRC won’t grant exemptions to nuclear plant, Legal News Line BY BRYAN COHEN, 2 Feb 12, NEW YORK – New York Attorney General Eric Schneiderman said Wednesday that the Nuclear Regulatory Commission has sided with his office by rejecting Indian Point’s request for more than 100 exemptions from major fire safety requirements.
Schneiderman filed a petition in March over what he says is Indian Point’s continual failure to comply with federal regulations for fire safety that were established to keep nuclear plants safe in an emergency. Read more »
USA radioactive leaks from nuclear reactors
the regulations in place for American facilities are actually more lax than one would expect.
the Nuclear Regulatory Commission has repeatedly weakened safety requirements for facilities, regularly allowing antiquated plants to continue operating by making it easier to pass
tests in lieu of actually upgrading the facility.
California nuclear plant shut down over radioactive leaks, RT Question More, 01 February, 2012, A leak at a Southern California nuclear facility that regularly provides power to roughly 1.4 million households has caused the plant to shut down a reactor.
Despite officials insisting that everything will be perfectly alright at the San Onofre nuclear site, this is not the first time as of late that power plants have raised serious questions about their safety in America. Read more »
New study on earthquake risks near USA nuclear plants
Quakes and U.S. Reactors: An Analytic Tool, NYT. By MATTHEW L. WALD With the release of a computer model of all known geologic faults east of Denver, nearly all of the nuclear power plants in the United States are about to embark on a broad re-evaluation of their vulnerability to earthquakes. The new mapping is the first major update of the fault situation for plants since 1989.
The map has been in preparation since 2008, well before the earthquake and tsunami that caused three meltdowns at Fukushima Daiichi in Japan last March or the quake near Mineral, Va., last summer that shook a twin-reactor plant beyond the degree expected. Still, those events have lent urgency to the effort to assess the American plants’ ability to withstand quakes.
The new study does not calculate the risk of damage from an earthquake or even specify how much ground motion is likely at the reactor sites. That work is left to the plants’ owners, supervised by the Nuclear Regulatory Commission.
The industry began to realize after the Fukushima disaster that engineers do not have a strong understanding of which structures and systems at the plants are most vulnerable…..
Not everyone is pleased with the route that the commission is taking when it comes to future construction. David Lochbaum, a reactor expert with the Union of Concerned Scientists, said that the agency had already approved sites for new reactors and designs for new reactors based on computer analyses of earthquake hazards.
If considerable study is needed on the quake vulnerability of existing reactors, he argues, the uncertainty surrounding the soundness of future plants must be even greater. “How can we know more about the reactors that haven’t been built than the ones that have been built?’’ he said. http://green.blogs.nytimes.com/2012/01/31/quakes-and-u-s-reactors-an-analytic-tool/

Nuclear power and water – theme for February 2012
FUKUSHIMA NUCLEAR PLANT and WATER – present state
That nuclear core is in direct contact with tons of water. And that containment, while not leaking down, is leaking out the sides. That contaminated water is going into every other building on site. And there is literally thousands and thousands of tons of water in other buildings. That water contains radioactive cesium, radioactive strontium, and it also contains nuclear fuel. There will be uranium in that water and plutonium in that water as well. We know for sure that that water is leaking into the ground water and into the Pacific Ocean. So while it is important to know that we are not going to release the nuclear core directly into the center of the earth, the problem is not over. And as a matter of fact, the problem will last for tens, perhaps even as long as 30 years because this contaminated water is in the basements of all the buildings on site. And not only does it contain cesium (that hangs around for 300 years), strontium (hangs around for 300 years), but it also contains plutonium and uranium and they have half lives of tens of thousands of years.
So the problem is, what do we do with all that water that is contaminated? It is already leaking into the groundwater. It is already leaking into the ocean. TEPCO is frantically catching it and putting it into tanks. But just today, TEPCO announced that they are running out of tank space on site, and eventually they are going to have to release those tanks into the Pacific Ocean. Now they will try to clean up some of the isotopes like cesium. But they have been unable to capture all the strontium. Strontium is a bone seeker that causes leukemia… http://fairewinds.com/content/fukushima-could-it-have-china-syndrome
NUCLEAR REACTORS - WATER USE : Per megawatt existing nuclear power stations use and consume more water than power stations using other fuel sources. Depending on the cooling technology utilised, the water requirements for a nuclear power station can vary between 20 to 83 per cent more than for other power stations.”- Dep of Parliamentary Services research note, 4 December 2006, no. 12, 2006–07, ISSN 1449-8456 Water consumption figures:
Nuclear: 2.3 L/ kWh
Solar (PV): 0.110 L/ kWh
Wind: 0.004 L/ kWh
(American Wind Energy Association estimate & US DOE)
A typical 1000-megawatt pressurized-water reactor (with a cooling tower) takes in 20,000 gallons of river, lake or ocean water per minute for cooling, circulates it through a 50-mile maze of pipes, returns 5,000 gallons per minute to the same body of water, and releases the remainder to the atmosphere as vapor. A 1000-megawatt reactor without a cooling tower takes in even more water–as much as one-half million gallons per minute. The discharge water is contaminated with radioactive elements in amounts that are not precisely known or knowable, but are biologically active.
Some radioactive fission gases, stripped from the reactor cooling water, are contained in decay tanks for days before being released into the atmosphere through filtered rooftop vents. Some gases leak into the power plant buildings’ interiors and are released during periodic “purges” and “ventings.” These airborne gases contaminate not only the air, but also soil and water. http://www.nirs.org/factsheets/routineradioactivereleases.htm

URANIUM MINING – OPEN CUT or UNDERGROUND It is very difficult to find figures on the amounts of water used. All mining is water intensive, but uranium mining is the greatest guzzler Water is extensively used to suppress airborne dust levels, to try to reduce the radioactive clouds that would otherwise emanate constantly from the uranium tailings.IN SITU LEACHING – Uranium Mining Process in-situ leaching uses a hydrogen peroxide mixture to strip the uranium from the rock, which kills tissue and destroys cells in human and animal life. The addition of oxygen and sodium bicarbonate called oxygenates causes uranium and other radioactive substances and trace metals to be liberated from the rock into the groundwater.
.. judges have too often taken the stance that they are judges who know nothing of the mining industry and accept the data of corporations, claiming the corporations are in the know.
..the water taken from the extremely pristine Westwater Canyon Aquifer near Crownpoint for uranium mining and used for flushing out chemicals would not be replaced in our lifetimes.
It takes hundreds, perhaps thousands of years, to transform aquifer water back into a drinkable condition. Virginia Against Uranium Mining: Scientists Back Navajos’ Uranium Mining Fight: Tribe fears contamination of drinking water
