Afternoon Report

From NEI’s Japan launch page

Radiation doses at the Fukushima Daiichi nuclear power plant continue to decrease. Radiation dose rates at the site boundary of the Fukushima Daiichi nuclear power plant ranged from 1 millirem to 3 millirem per hour on March 18. Eighteen locations were monitored in a 30 kilometer to 60 kilometer radius of the plant. The highest radiation dose rate at any of those locations was 14 millirem per hour.

Tokyo Electric Power Company (TEPCO) is installing high voltage cables from a nearby transmission line to reactors 1 and 2 at Fukushima Daiichi. Power is expected to be restored to reactors 1 and 2 later today (Saturday, March 19, Japan time). Priority is being given to restoring power to residual heat removal and cooling water pumps at the reactors. Plans are being made to extend high voltage cables to reactors 3 and 4 by March 21.

TEPCO also is stepping up efforts today to add water to the used fuel pool at reactor 4.

Two diesel generators are running and supplying electrical power to Reactors 5 and 6 at Fukushima Daiichi. A residual heat removal pump, powered by a diesel generator, is providing cooling to the spent fuel pool at reactor 5. Temperature in the spent fuel pool at reactor 5 is “high, but decreasing” according to Japan nuclear industry sources.

There has been no change in the primary reactor containment structures at the Fukushima Daiichi plant. Crews are still pumping seawater into the reactors 1, 2 and 3 to cool the fuel.

All four reactors at Fukushima Daini have reached cold shutdown conditions with normal cooling being maintained using residual heat removal systems.

U.S. Public Opinion Data

U.S. public opinion on the safety of nuclear energy is relatively unchanged from 2008 levels despite the Fukushima accident, and 60 percent of Americans surveyed said the situation in Japan has made no difference in how they feel about nuclear energy in the United States.

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…
