Tuesday Afternoon Update

From NEI's Japan Earthquake launch page:

UPDATE AS OF 3 PM EDT, TUESDAY, MARCH 29:

Plutonium found in five soil samples at the Fukushima Daiichi nuclear power plant complex originated from uranium fuel at the plant, Tokyo Electric Power Co. has determined. The level of radiation from the plutonium is not considered dangerous to human health.

The company on March 28 said that some of the plutonium—which is at a very low level—could have been the result of fallout from atomic weapons tests during the Cold War.

Fresh water is being injected into reactors 1, 2 and 3 to cool fuel in the reactors. Workers have switched from diesel fire pumps to temporary electric pumps to move water into the reactors. U.S. Navy barges filled with fresh water have arrived at the site with much-needed supplies of fresh water to pump into the reactors and used nuclear fuel storage pools.

TEPCO also continues to clean contaminated water from the basements of the turbine buildings at the three reactors. The water is being pumped into the main condenser for each reactor. Workers also are working to drain water remaining at unit 4.

As reported earlier, radioactive water has been found in concrete-enclosed channels that hold piping and cables outside of the reactor 1, 2, and 3 turbine buildings. TEPCO is assessing the best way to remove the water from these structures. None of the trenches empty directly into the sea near the Fukushima plant.

NEI’s Pietrangelo Briefs Senate Energy and Natural Resources Committee

Tony Pietrangelo, NEI senior vice president and chief nuclear offer, briefed members of the Senate Energy and Natural Resources Committee on events in Japan and steps U.S. companies are doing to ensure safety and emergency preparedness at nuclear energy facilities.

I compliment Mr. Pietrangelo for artfully correcting Sen. Franken. Re: Evacuation. I would recommend that the NCR use the same mass evacuation plans which would/must be used in the event of a virulently lethal biological warfare agent/microbe release in an urban environment. Surely there are contingencies for that -- right? What agency would be responsible for such a critical mass evacuation plan in a world of terrorism and super-lethal engineered biologics?

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…

Innovation Fuels the Nuclear Legacy: Southern Nuclear Employees Share Their Stories

Blake Bolt and Sharimar Colon are excited about nuclear energy. Each works at Southern Nuclear Co. and sees firsthand how their ingenuity powers the nation’s largest supply of clean energy. For Powered by Our People, they shared their stories of advocacy, innovation in the workplace and efforts to promote efficiency. Their passion for nuclear energy casts a bright future for the industry.

Blake Bolt has worked in the nuclear industry for six years and is currently the work week manager at Hatch Nuclear Plant in Georgia. He takes pride in an industry he might one day pass on to his children.

What is your job and why do you enjoy doing it?
As a Work Week Manager at Plant Hatch, my primary responsibility is to ensure nuclear safety and manage the risk associated with work by planning, scheduling, preparing and executing work to maximize the availability and reliability of station equipment and systems. I love my job because it enables me to work directly with every department on the plant…
