Evening Report

From NEI’s Japan Earthquake launch page:

UPDATE AS OF 7 PM EDT, MARCH 22:

Tokyo Electric Power Co. reported this afternoon (U.S. time) that it has restored electricity to the control room at the Fukushima Daiichi reactor 3. Lights in the control room were switched on for the first time since the earthquake 11 days ago. Electricity to the reactor 4 control room is expected to be restored shortly.

Power restoration to the control rooms will help technicians as they seek to repair the two reactors’ cooling systems. Workers are seeking to reactivate control room monitoring systems for reactor parameters, such as reactor coolant temperatures and water levels. The company also reported that thermometers at reactors 1, 2 and 3 are working again.

TEPCO said it would try to reactivate a cooling pump for reactor 3 later today or Wednesday (U.S. time). The company said that if the pump functions normally, it could begin cooling the reactor and the spent fuel storage pool.

Workers at the Fukushima Daiichi plant also continued to spray water into the used fuel pools of reactors 3 and 4. A 160-foot long extension arm normally used to pour concrete for high-rise buildings was used to more accurately spray water into the used fuel pool area of reactor 4. Workers also pumped 18 tons of seawater into the reactor 2 used fuel pool.

Japan's health ministry says it detected radioactive iodine levels in tap water above the national safety standard for infants at five locations in Fukushima Prefecture. The agency says the water does not pose an immediate risk to infants, but is advising against consumption of the water or adding water to powdered milk for infants.

Elevated levels of radioactive iodine and cesium were detected in soil about 25 miles from Fukushima Daiichi, but the levels do not pose a health risk, according to Japan’s science ministry.

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…
