Second Japanese Utility Submits Stress Test Results to Regulator

November 16, 2011

Industry/Regulatory/Political

  • Shikoku Electric Power Co. has submitted the results of first-phase stress tests for its Ikata Unit 3 reactor to the Nuclear and Industrial Safety Agency. The results show Ikata 3 could withstand an earthquake with ground acceleration 1.9 times as strong as the reactor’s design basis and a 47-foot tsunami, four times its design basis. Shikoku Electric is the second utility to submit a stress test result after Kansai Electric did so for its Ohi Unit 3 reactor Oct. 28.
  • Chubu Electric Power Co. has begun building a 1-mile-long seawall to protect Hamaoka nuclear energy facility against tsunamis. The wall is designed to withstand a tsunami 59 feet high and will cost $1.3 billion. It is to be completed by December 2012. Of the five reactors at the site, reactors 1 and 2 are permanently shut, reactor 3 has been closed for periodic inspection since November 2010, and reactors 4 and 5 were shut down in May after the March 11 earthquake and tsunami.

Plant Status

  • Mitsubishi Heavy Industries said Nov. 15 it is installing the first of eight 90-cubic-meter storage tanks at Fukushima Daiichi. The tanks will be used to store sludge from water decontamination operations. Installation of the tanks is to be completed by April. Tokyo Electric Power Co. told journalists last week that 77,500 metric tons of water still needs purification treatment.
  • Nuclear Engineering International reported that TEPCO has sealed stairwells, hatches and other penetrations leading to the basements of turbine halls and other buildings at Fukushima Daiichi. The measure is meant to reduce the spread of radioactive dust as the company pumps water from the basements to decontaminate and recycle it for reactor cooling.

Media Highlights

  • The International Atomic Energy Agency’s final report to the Japanese government from its October inspection of the areas surrounding Fukushima Daiichi recommends Japanese authorities take a “balanced approach” in prioritizing cleanup efforts. It also recommends local disposal of contaminated soils and other materials from remediation efforts and offers IAEA assistance if requested.
  • Dow Jones reports that a panel has been set up to advise the Japanese Ministry of Economy, Trade and Industry on the need to revise safety regulations for the country’s older nuclear reactors.
  • Platts reports that as Japan’s nuclear energy utilization plummeted to a record low of 18.5 percent, the country’s 10 major electric utilities have consumed six times more oil this October than they did the same time last year.

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…
