The U.S. Nuclear Renaissance: Forgings Now!

On Tuesday, I wrote about a nuclear fabrication shop in Indiana. Today, there was an equally exciting press release from UniStar Nuclear:
UniStar Companies First to Procure Components for First Potential Nuclear Power Plant in Nearly Three Decades

Constellation Energy ... and AREVA today announced that through their jointly developed UniStar business model they have entered into agreements to procure the long lead materials necessary to construct the first potential U.S. nuclear power plant of a planned U.S EPR fleet. Of the several U.S. companies considering the construction of new nuclear plants, Constellation Energy and AREVA, through the UniStar business model, are the first to procure the necessary raw materials.

This procurement includes 44 heavy forgings for a planned U.S. Evolutionary Power Reactor (EPR) to be supplied by AREVA. The forgings - needed for the reactor pressure vessel and steam generators - will be produced at international facilities. The completed forgings will be manufactured into final components at BWX Technologies' (BWXT) facility in Mount Vernon, Ind., or AREVA's facility in Chalon-St. Marcel.
(My guess is that the "international facilities" that will produce the forgings are at Japan Steel Works.)

My initial reaction this news was that these guys have a lot of guts. After all, they don't have an early site permit, and the design certification papers for the EPR have not been submitted to the NRC yet. One of my coworkers noted, however, that it might not be as big a risk as you would think. After all, there is an EPR under construction in Finland, and one is in the works for France. If nuclear licensing proves too cumbersome in the U.S., UniStar can probably sell the forgings in Europe, maybe even at a profit. A standardized design and a global market can be handy.

It is becoming ever more obvious that this so-called "renaissance" is more part ruse than part pipe dream. An agreement to forge materials that can be used in other industries demonstrates little more than that.

Call it what you will. You're going to see many more utilities ordering parts way in advance over the next few years.

A minor clarification. These forgings could be used in "other countries" not "other industries". These would still be uniquely nuclear components and do represent an investment in the future of the nuclear industry.

In fact, new designs are proposed with the use of less "nuclear grade" parts for a host of safety systems and instead rely upon "commercial grade" parts.

That means less quality control and assurance. This all comes out as the "solution" to the nuclear industry's decades old problem of substand and counterfeit parts for safety related systems and components.

A not so minor point and trade off of safety for cost.
Safety does not equal reliability.

The current 90%+ capacity factors are a problem, not an advantage, because no power plant reasonably needs more than about 75%. These designs rely not on the parts being reliable, but on the laws of physics. Using commercial-grade components will reduce costs, and that's it.

Unless, Mr. Gunter, little green aliens come down from the planet Zorkon with an anti-gravity beam. Would you like that to be a design-basis accident?
Furthermore, what's so magical about a steam system that happens to be connected to a nuclear heat source? Or, for that matter, an electrical system that happens to be at a nuclear power plant? They're steam systems and electrical systems, nothing more, and need nothing special--especially given these plants' passive safety.

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…
