TEPCO Initiates Gas Sampling for Reactors 1, 2

Plant Status

• Workers at Tokyo Electric Power Co.’s (TEPCO) Fukushima Daiichi nuclear energy facility in Japan will begin sampling gases inside containment at reactors 1 and 2 to obtain more accurate data on the types and amount of radioactive substances being released. TEPCO hopes that analysis of the samples will help determine the extent to which nuclear fuel from the reactors is leaking into containment. The gases will be extracted through pipes and analyzed on the first floor of the reactor buildings. Radiation measurements thus far have been based on readings taken on the facility premises. Sampling is scheduled to begin today at reactor 1 and in early August at reactor 2. TEPCO has not yet made plans for sampling at reactor 3, where radiation levels remain high. This is because TEPCO only began injecting nitrogen into reactor 3 on July 15 to minimize the risk of a hydrogen explosion. Nitrogen injection into reactors 1 and 2 began in April and June.

• TEPCO plans to issue an updated roadmap to recovery at the Fukushima Daiichi facility in mid-August. Industry/Regulatory/Political Issues

Industry/Regulatory/Political Issues

• The U.S. Nuclear Regulatory Commission held a public meeting with stakeholders July 28 to discuss the agency’s near-term task force recommendations for safety enhancements at U.S. nuclear energy facilities after the Fukushima accident. Numerous stakeholders, including the industry, called for a thorough and methodical review of accident details as they become available so that regulatory actions are consistent with lessons learned. In the next several weeks, the five-member commission is expected to provide direction to the NRC staff on next steps.

• Japanese Chief Cabinet Secretary Yukio Edano has ordered the governor of Miyagi Prefecture to suspend all shipments of beef cattle after levels of cesium above the government safety limit were detected in some cattle raised there. Miyagi is the second prefecture to have cattle shipments banned. Fukushima Prefecture received a suspension order last week.

Upcoming Events

• The U.S. Senate Committee on Environment and Public Works will hold a hearing Aug. 2 to review the NRC’s near-term task force recommendations for enhancing reactor safety. The witness list has not been announced.

Here's a fun one : News item in the Brattleboro Reformer week of Sept. 1rst 1979 : 200, 000 gallons of radioactive water into the Connecticut river from Vermont Yankee nuclear plant.
Official comment from the plant : - "amounts are so little they won't be detected in the fish "
More than 30 years later news item in the Rutland Herald July 6 2010 :

Strontium 90 detected again in fish in the Connecticut river.

Official comment from the plant:
- Strontium 90 is from nuclear testing in the 1960's and Chernobyl...
Liar! Liar! Pants on fire !!!
Actual radioactive effluent reports
to the NRC ? Strontium 90 produced at the plant from 2002 to 2005.
Half life ? 28.7 years !!!
Vermont Yankee officials had to back step and say they found some
Strontium 90 between two buildings.

The really funny thing, Anonymous, is that you are the one engaged in deception.

Where were those fish found, in 2010?
Upstream of the plant. By no small distance. Nothing to do with any releases from the plant, and emphatically due to weapons background.

On to the leak which produced the tiny quantities of tritium that allowed Shumlin to upset Vermonters... How far had the miniscule amounts of strontium-90 travelled from the pipe tunnel? A few feet.

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…
