Unit 3 Leaking Alpha Radiation
TEPCO put out a report on
alpha emitters found in the gas removal systems for units 1-3. This
appears to be the first reporting of this.
Units 1 and 2 were tested and said to be below detection. Unit 3 is
leaking a certain amount of alpha emitters out the gas removal system
and is likely leaking the same out the damaged reactor well on the top.
Some of the isotopes listed are expected. What appears unusual is that
only unit 3 is cited as detecting them. Since unit 3 was running a
partial load of MOX plutonium fuel is this a roundabout admission by
TEPCO that 3 is leaking detectable amounts of plutonium due to the fuel
mix?
Since TEPCO plays coy, or possibly lazy and only lists “all alpha”

TEPCO Admits Containment Failure At Unit 3
Most in the know have
strongly suspected this since 2011 but TEPCO finally admitted this
today. Unit 3′s containment structure is failed via the reactor well.
This came about as the press questioned TEPCO about the ongoing steam
leak source at unit 3. TEPCO had been declaring it to be rain leaking
onto a warm structure up until now.
Ex-SKF translates this from the TEPCO PR representative at today’s press
conference:
“it was around this area where the steam was coming from inside the
reactor’s Containment Vessel right after the accident [explosion of
Reactor 3 on March 14, 2011"]

UPDATE: New Radiation Readings At Unit 3 Reactor Well
TEPCO released some
additional radiation readings for the reactor well of unit 3 today. They
can be seen below on an overlay of the heat image released previously.
These readings show that the high readings released yesterday are not
isolated and that the entire reactor well area is quite high in
radiation. There does appear to be some focal effect coming off of the
source of the hot spot (temperature) area.

TEPCO Releases Unit 3 Radiation Levels, Shows New Problem
TEPCO published this new
document today that includes more radiation readings for the reactor
well of unit 3. These new readings done as an overlay on the recent
heat image really shows the problem. The highest readings are focused on
the heat readings. The area near the spent fuel pool gate are higher
and the location where the steam is leaking is elevated compared to the
adjacent readings.
This still requires more analysis to determine what may be going on
beneath the thick concrete reactor well cover. The readings are all
considerably high with many higher than what was found at unit 2. Unit 2
has been sealed off after TEPCO discovered extremely high levels of
radiation were leaking out the blow out panel of the refueling floor at
that unit.

Unit 3 Fukushima Daiichi Debris Removal Near Completion
Debris removal has been
ongoing during the last month as TEPCO attempted to distract the public
with the leaking ponds issue. Photos below from the TEPCO webcam show

Unit 3 Location Of Crane & Mast In Pool
In an attempt to better
understand how the crane is situated in the spent fuel pool of unit 3 we

spent fuel pool.
The first flat map shows the crane location in green and the mast in
pink per TEPCO’s original version of the map. The red blocks are known
location of fuel based on a 2010 photo of the spent fuel pool.
Additional fuel may have been offloaded into the pool since the photo
was taken.

Unit 3 Daiichi Pool Accident Analysis
TEPCO announced this week
that the 1.5 ton mast for the refueling crane fell into the pool and
sank as they tried to remove debris from the pool. TEPCO has done some
testing of radiation levels near the pool and does not think there was
fuel damage based on not finding drastically elevated levels.
The mast falling could create a couple of potential damage situations.
It could fall and damage the fuel assemblies held in the pool. It could
also damage or puncture the spent fuel pool metal liner causing a leak
in the pool. The condition of the liner or the concrete pool has not
been confirmed by TEPCO to date.
The mast that fell looks like this under normal conditions. It has
minimal connections to the refueling crane.

Atomic Rats, Fishing For Beams & Cleaning Up The Common Pool At Daiichi
Workers at the plant are
reporting seeing rats at Daiichi. Worker Happy11311 mentioned seeing
them and was worried they would damage cables at the plant. They could
cause obvious safety problems if they chewed on electrical or water
lines. Small animals also pose the risk of getting into equipment and
causing issues by tripping electrical systems. Then there is the problem
of rats being in contact with high levels of radiation then making them
highly contaminated. This can cause problems as they then spread the
contamination up the food chain or take it with them if they leave the
immediate area.

Robot Inspection Of Unit 3 Finds Increasing Radiation Levels, New Robot Fails.
TEPCO reports the results
of a robot inspection in unit 3 at Fukushima Daiichi. The initial work

containment.
The new robot FRIGO-MA failed to work due to a bug. TEPCO sent in
Packbot and Quince instead. TEPCO did not state the nature of the
inspection other than to look at the gas duct hose. It appears the
concern was due to increasing radiation levels in the area. TEPCO was
likely inspecting the duct as the source of the possible increase. No
leaks or damage were found on the duct.
What they found was that the containment door and track were the source
of the increased radiation levels. Workers had a .52 mSv exposure dose

TEPCO Inspects Gas Control & Introduces A New Robot
TEPCO announced they are

They do not say why they are inspecting the “duct” that looks more like a
reinforced hose. This duct was quite obviously installed by humans at
some earlier date yet TEPCO never reported this specifically. Now they
will send in robots because the radiation levels are too high.
While this is good as far as protecting workers and using robots for
mundane tasks, the exposures of the workers that installed the duct were
likely quite high. The worker seen in the image is wearing a yellow
protective suit seen when workers have to go into extremely high

Indecision, Handouts And Heating Up Fuel Pools
The NRA panel of experts
was supposed to decide today if the Oi nuclear plant would be allowed to

TEPCO says it needs $125 billion USD to continue making compensation
payments and to cover the cost of decontaminating areas covered in
fallout from the leaking nuclear plant. This amount is equal to 2% of
Japan’s GDP. A recent video stated these costs were only to cover
possibly the next two years. Some experts said the constant need for
huge sums of money to deal with the nuclear disaster would turn TEPCO

TEPCO Sending Workers Into Units 2 & 3 Basements In A Few Hours
TEPCO intends to send
workers into the sub basement of units 2 and 3 on March 14th (a few

The work will consist of checking for radiation levels, temperature,
humidity, water levels etc. and possibly opening the door into the torus
room. TEPCO thinks workers will receive a dose of 10 mSv each for the
trip. This work could be both risky and significant since there is some
speculation that corium or at least very highly radioactive water may
reside in the torus.
Unit 3 currently shows as .2 sV/h torus radiation
Unit 2 currently shows at 16 sV/h torus radiation at the “B” sensor.
TEPCO has this flagged as failed. If this reading is accurate that is a

1.6 Sievert Hot Spot Found In Unit 3
Recently a 1.3 Sievert hot

assumed to be leaking from the containment structure and the areas near
the hatch are also very high. Unit 3 has had an ongoing problem of

Fukushima Unit 3 steam-explosion theory
Fukushima Unit 3
steam-explosion theory
by Ian Goddard
The signature event of the Fukushima nuclear meltdowns was the large
mushroom-cloud explosion of Unit 3 on March 14th. In contrast, the
explosion of Unit 1 lacked any notable vertical projection. Yet Tokyo
Electric Power Company assumes each was a hydrogen explosion in the
upper-deck above the reactor. However, because dramatically different
effects suggest different causes, let us consider an evidence-based
model wherein the Unit-3 explosion was a steam explosion that vaporized
tons of injected seawater into a mushroom cloud and that triggered
secondary hydrogen explosions.
Figure 1: Unit 1 lacked the vertical magnitude and mushroom cloud of
Unit 3.
So it seems something extra happened at Unit 3. The mushroom cloud
is composed of tons of mass consistent with tons of vaporized water.
The risk of a steam explosion during a meltdown in … Read entire article »

More Censorship In Japan And Worldwide
A Japanese blogger has
documented multiple instances of the video of unit 3 exploding being
removed from YouTube. He included links to specific videos along with
the take down date. One states that Fukushima Central Television has
forced the take down of these videos. This raises questions about their
ability to force censorship on a service that resides outside Japan. A
US blogger had a similar video taken down but his used a portion of one
of the unit 3 explosions in a larger video. He was able to get that
video reinstated by You Tube.
(Editors note: I also had a video of unit 3′s explosion removed from my
You Tube account)
The unit 3 explosion video was shown by many news outlets throughout the
world and it is unclear if … Read entire article »

TEPCO Releases Document Claiming Unit 3 Blew Up Unit 4
TEPCO released a schematic
claiming it explains that unit 3 caused the explosion in unit 4. It
shows high radiation readings in the exhaust treatment equipment of unit
4 and states that there was a backflow of gas into unit 4.
If this is the case and unit 3 had so much hydrogen generating ability
that it destroyed two reactors in massive explosions what does that say
about MOX fuel safety?

Removal Of Spent Fuel In Units 3 & 4 Made A Priority
No additional details are
given such as how the fuel will be removed or how quickly. TEPCO has
announced that the removal has become a priority on the next phase of
work.
Having TEPCO recognize the urgency of doing this is a small step
forward.

New Steps to Strengthen the Nation’s Energy Infrastructure
New Steps to Strengthen the Nation’s Energy Infrastructure
By US Department of Energy
Editor’s note: This article originally appeared on the White House blog.
Today, President Obama signed a memorandum establishing the federal government’s first Quadrennial Energy Review (QER) process, fulfilling an important commitment from his Climate Action Plan and ensuring that federal energy policies continue to meet the nation’s economic, environmental and security goals. Over the next four years, the QER will provide a comprehensive review of these policies in the context of a changing energy landscape.
The ways that this country produces and uses energy are changing in ways that few people could have predicted a decade ago. As an Administration we’ve pursued an all-of-the-above energy strategy, and, as a result, we are now more energy secure than at any time in recent history, and we have cut our carbon pollution in the process. We have more than doubled our production of electricity from wind and solar since the President took office, and we have set a goal to double it again by 2020.
We are also producing more of our own conventional fuels. The United States is now the number one natural gas producer in the world, and, for the first time in decades, the United States is now producing more oil at home than it imports from abroad. These are important steps to reduce America’s dependence on foreign oil and responsibly leverage our nation’s home-grown energy resources.
At the same time, Americans and people around the world are already experiencing the very real impacts of climate change. These include increased prolonged periods of excessively high temperatures, more heavy downpours, and more severe droughts — all of which pose far-reaching consequences for American families, communities and businesses. That’s why the President is taking steady, responsible steps to cut greenhouse gas pollution to protect our kids’ health and begin to slow the effects of climate change, leaving a cleaner, more stable environment for future generations.
The QER process launched today is designed to further address the challenge of leveraging America’s domestic energy resources while strengthening our energy security and the health and resilience of our planet for future generations.
The first installment of the QER review will focus on America’s infrastructure for transmitting, storing and delivering energy — much of which was built decades ago. This includes the 200,000 miles of high-voltage transmission lines, 2.2 million miles of local distribution circuits that make up our nation’s electric grid, 300,000 miles of transmission pipelines and hundreds of processing plants and underground storage facilities that make up America’s natural gas infrastructure network.
Over four years, successive installments of the QER will provide a comprehensive set of recommendations on how best to transform America’s energy production, delivery and consumption systems to meet the challenges of the 21st century. The QER will identify important opportunities to modernize, expand, replace or transform our energy infrastructure system so that it better accommodates changes in energy supply, integrates cutting-edge information and security technologies and meets increasing demand for new consumer services.
And because of the complexity of the U.S. energy system — including its regional nature, substantial private-sector ownership and the multi-layered network of regulations that govern it — we know that a successful QER will require the active participation of many federal agencies and close engagement of partners in Congress, civil society, the private sector and state, local and tribal governments.
Together, we are poised to craft a blueprint for modernizing our energy system and increasing America’s competitiveness. We look forward to delivering the first installment in January 2015 and creating opportunities to solicit broad stakeholder input as we embark on this important task.

NRC MEETS TO TALK POST-FUKUSHIMA RECOMMENDATION
NRC MEETS TO TALK POST-FUKUSHIMA RECOMMENDATION: NRC
leadership today is holding its first public meeting with staff,
industry and outside groups to discuss one of the agency's most
difficult post-Fukushima safety recommendations, No. 1: Clarifying the
NRC's regulatory framework. Agency staff released a paper and several
supplemental documents on the subject last month. NRC commissioners will
get commentary this morning from the Nuclear Energy Institute, the
International Atomic Energy Agency, the Union of Concerned Scientists
and a lengthy panel of NRC staff members (The agenda: http://1.usa.gov/1gO47He).
Among the conclusions the staff plan to present is the recognition that
"Some improvements to framework are warranted to enhance clarity,
efficiency, and effectiveness of NRC’s regulatory process," including
added clarity around the role of voluntary industry initiatives in the
agency's regulatory process. The meeting begins at NRC headquarters in
Rockville, Md., at 9 a.m. Webcast: http://video.nrc.gov/
