Monday Evening Update

From NEI's Japan Earthquake launch page:

UPDATE AS OF 7 P.M. EDT, MONDAY, MARCH 28:
The International Atomic Energy Agency said that Japan's Nuclear and Industrial Safety Agency is planning a meeting with Tokyo Electric Power Co. to determine the origin of contaminated water in the turbine buildings at the Fukushima Daiichi nuclear power plant.

Contaminated water from the basement floor of the reactor 1 turbine building is being pumped into its main condenser. At reactor 2 that process has not begun because the steam condenser is full, IAEA said. Pumping contaminated water is being considered at reactors 3 and 4.

Three workers who received radiation exposure from standing in contaminated water were released today from the National Institute of Radiological Sciences, where they had been under observation. The level of localized exposure received by two of the workers is between 200 to 300 rem, lower than the previous estimate of 200 to 600 rem, IAEA said.

Radiation Monitoring Continues

Results from ocean monitoring stations up to 18 miles off the shoreline from the Fukushima Daiichi plant showed levels of iodine-131 at most locations were below federal limits. IAEA said results from four monitoring stations on March 26 showed iodine-131 concentrations were between 162 and 486 picocuries (1 picocurie is one-trillionth of a curie) per liter. Cesium-137 concentrations ranged from below the level of detection up to 432 picocuries per liter.
IAEA said that it is still too early to draw conclusions for expected concentrations in marine food, because the situation can change rapidly.

The latest sampling shows that drinking water in Fukushima and Ibaraki prefectures remain below the Japanese limits for the ingestion of drinking water by infants. Iodine-131 was reported in food samples taken from March 26 to March 27 in six prefectures (Fukushima, Gunma, Ibaraki, Niigata, Tochigi and Yamagata) in vegetables, strawberries and watermelon.

The U.S. Environmental Protection Agency identified trace amounts of radioactive isotopes at its 12 RadNet air monitor locations across the nation. The levels are extremely low and are far below levels that would be a public health concern. EPA's samples were captured by monitors in Alaska, Alabama, California, Hawaii, Idaho, Nevada and Washington state over the past week and sent to EPA scientists for detailed laboratory analysis.

The Austrians report massive emissions from the plant equivalent to 10% of the Chernobyl total every day, mostly iodine 131 but also about 10% cesium 137.
They base this on the CNTBT monitoring network.
The web site http://www.zamg.ac.at/ is in German but the tables and dispersion maps are self explanatory.
These emissions have been blown to sea almost continuously since the accident, but are not reported anywhere else.
If the wind shifts, they will come as a severe shock to the Japanese people.
Could someone knowledgeable explain how long these emissions are projected to continue, where they come from and what is their likely impact.

It'd help further dispell radioation's eternally virulent "creeping glowing fog" perception if the AP put into contrast how weak these traces are; that such are found in volcanic eruptions, and that were there detectors so designed one could detect particulates from Chinese coal-fired plants in the U.S. or sand from Sahara sandstorms.

Already cable busuness shows are inviting more and more biased "consultants" announcing that this is the "final nail in the coffin for nuclear energy" and Greenpeace has started to "review" even thermonuclear fusion on their anything nuclear exorcism list.

Where is the nuclear industry's demand to have the media fair and balanced?

netudiant, there are not massive emissions coming out of the plant. That implies the reactor cores are exposed like Chernobyl and that's not the case. A piece in the BBC news explains that the "radioactive fallout at Fukushima is less than 1% of that at Chernobyl."

jimwg, the whole nuclear industry is mobilized and talking with the media as much as possible. Of course, it would be easier if the media only listened to us (ha ha), but that's simply not the case. We just have to continue to present the facts and help folks under the situation and put it into perspective. I'd have to say not all is bad with the media, there are quite a number of good pieces out there which we've tried to highlight. If you have ideas on how the industry could be more effective, please share them.

The only way the media is going to give equal treatment to nuclear is when you are spending as much on daily advertising as the oil/gas/coal industry. In the meantime, for every reactor-year of delay, postponement, or premature cancellation they can create, the fossil energy interests make an extra $365 million in revenue. Tilting the media is a pay-to-play game.

Nuclear was an industry created by scientific geniuses, and destroyed (in the democracies anyway) by media executives, politicians, and lawyers.

Making Clouds for a Living

Donell Banks works at Southern Nuclear’s Plant Vogtle units 3 and 4 as a shift supervisor in Operations, but is in the process of transitioning to his newly appointed role as the daily work controls manager. He has been in the nuclear energy industry for about 11 years.

I love what I do because I have the unique opportunity to help shape the direction and influence the culture for the future of nuclear power in the United States. Every single day presents a new challenge, but I wouldn't have it any other way. As a shift supervisor, I was primarily responsible for managing the development of procedures and programs to support operation of the first new nuclear units in the United States in more than 30 years. As the daily work controls manager, I will be responsible for oversight of the execution and scheduling of daily work to ensure organizational readiness to operate the new units.

I envision a nuclear energy industry that leverages the technology of today to improve efficiency…

Nuclear: Energy for All Political Seasons

The electoral college will soon confirm a surprise election result, Donald Trump. However, in the electricity world, there are fewer surprises – physics and economics will continue to apply, and Republicans and Democrats are going to find a lot to like about nuclear energy over the next four years.

In a Trump administration, the carbon conversation is going to be less prominent. But the nuclear value proposition is still there. We bring steady jobs to rural areas, including in the Rust Belt, which put Donald Trump in office. Nuclear plants keep the surrounding communities vibrant.

We hold down electricity costs for the whole economy. We provide energy diversity, reducing the risk of disruption. We are a critical part of America’s industrial infrastructure, and the importance of infrastructure is something that President-Elect Trump has stressed.

One of our infrastructure challenges is natural gas pipelines, which have gotten more congested as extremely low gas prices have pulled m…

Nuclear Is a Long-Term Investment for Ohio that Will Pay Big

With 50 different state legislative calendars, more than half of them adjourn by June, and those still in session throughout the year usually take a recess in the summer. So springtime is prime time for state legislative activity. In the next few weeks, legislatures are hosting hearings and calling for votes on bills that have been battered back and forth in the capital halls.

On Tuesday, The Ohio Public Utilities Committee hosted its third round of hearings on the Zero Emissions Nuclear Resources Program, House Bill 178, and NEI’s Maria Korsnick testified before a jam-packed room of legislators.


Washingtonians parachuting into state debates can be a tricky platform, but in this case, Maria’s remarks provided national perspective that put the Ohio conundrum into context. At the heart of this debate is the impact nuclear plants have on local jobs and the local economy, and that nuclear assets should be viewed as “long-term investments” for the state. Of course, clean air and electrons …
