Saturday Update

From NEI's Japan Earthquake launch page:

UPDATE AS OF 12:00 P.M. EDT, SATURDAY, APRIL 2

Recovery efforts continue at the Fukushima Daiichi nuclear plant in Japan, as aid pours in from the international nuclear community in the form of technical expertise, protective equipment for workers, storage tanks for contaminated water and other measures.
Today, Tokyo Electric Power Co. (TEPCO) said it has identified one likely source of contaminated water reaching the Pacific Ocean, accounting for some of the radiation readings in seawater samples taken over the past several days. The crack is in a two-meter-deep concrete “pit,” or trench, that contains power cables near the reactor 2 water intake. Water measuring between 10 and 20 centimeters deep was found in the pit with radiation levels of more than 1,000 milliSieverts per hour. TEPCO plans to pour concrete to patch the crack while continuing to search for other potential leak paths.
The Nuclear Industrial and Safety Agency says iodine-131 will be diluted in seawater and does not pose a threat to the public. Additionally, iodine-131 has a short half-life—about eight days—and will decay to harmless levels fairly quickly. (See NEI's fact sheet to learn more about the health impacts of iodine-131.)
The Japan Atomic Industrial Forum said TEPCO is obtaining a “massive, hollow floating platform” from Shizuoka City and will use it to store contaminated water from the Fukushima site. The float can store up to 18,000 tons of water. Meanwhile TEPCO and the Japanese government are working to identify safe methods for transporting and storing contaminated water.

NRC Forms Task Force to Review U.S. Safety Measures
The U.S. Nuclear Regulatory Commission announced April 1 that it has formed a task force to identify any potential near-term actions that affect U.S. nuclear power plants, including their used fuel pools. This is part of the NRC’s 90-day review of U.S. safety measures in light of what is known to date about the March 11 earthquake and tsunami. The review will encompass station blackout (loss of all offsite electrical power for a reactor), external events that would lead to a prolonged loss of cooling, plant capabilities for preventing or dealing with such circumstances and emergency preparedness. The task force will provide status reports in public meetings May 12 and June 16 and recommendations at a July 19 public meeting.

The Nine Inch FISSURE

Not to single out FoxNews since other media players have proven as "unprecise", but I'm almost amused when Fox's Japan reporter Dominic is echoing the alarmist news banners of the day about the doomsday leak, as though were talking about the Titanic's infamous 300 foot rip. Though Japan hasn't come out with the stats, I think in lieu the dimensions and volume of the trench involved, it's safe to assume there's no dam-busting Torrent roaring into the Pacific as cable news coyly speculates than prehaps several gallons per minute (how long would that take to empty your pool?). Wouldn't it behoove the media's passion for unbiased accuracy in information to mention such?

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…

Why America Needs the MOX Facility

If Isaiah had been a nuclear engineer, he’d have loved this project. And the Trump Administration should too, despite the proposal to eliminate it in the FY 2018 budget.

The project is a massive factory near Aiken, S.C., that will take plutonium from the government’s arsenal and turn it into fuel for civilian power reactors. The plutonium, made by the United States during the Cold War in a competition with the Soviet Union, is now surplus, and the United States and the Russian Federation jointly agreed to reduce their stocks, to reduce the chance of its use in weapons. Over two thousand construction workers, technicians and engineers are at work to enable the transformation.

Carrying Isaiah’s “swords into plowshares” vision into the nuclear field did not originate with plutonium. In 1993, the United States and Russia began a 20-year program to take weapons-grade uranium out of the Russian inventory, dilute it to levels appropriate for civilian power plants, and then use it to produce…

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…
