Exelon and Constellation Merge; E.ON; Japan

Here's the news, via World Nuclear News:
Exelon and Constellation Energy have announced a $7.9 billion merger. Under the name Exelon, the resulting firm will be America's largest generator of nuclear power by an even greater margin. 

A definitive agreement posted today will see a stock-for-stock transaction combine the two companies. The new firm wants to take advantage of Exelon's large low-carbon generation fleet and Constellation's customer-facing business. 
The CEO's of the two company's, John Rowe of Exelon and Mayo Shattuck of Constellation, and Exelon's COO Chris Crane, held a press conference about this a little earlier today, so there'll be more on this later. 

Exelon is headquartered in Chicago and Constellation in Baltimore; the former has full or majority share in 17 nuclear reactors at 10 sites while Constellation Energy nuclear Group operates operates five reactors at three power stations - Maryland's Calvert Cliffs and New York's R.E. Ginna and Nine Mile Point.

Stay tuned.

Over in Germany, E.ON's chief Johannes Teyssen tries to make the case for nuclear energy while not getting sticks thrown at him:

Speaking at a televised session of a commission to evaluate ethical questions related to atomic power generation, Teyssen said nuclear energy should be regarded as a "bridge technology" to help the country's transformation to a low-carbon, renewable energy supply.

"Germany unconditionally...needs to retain its ability the achieve its internationally binding climate protection commitments," Teyssen told a panel of energy experts from industrial companies, utilities, scientists, energy associations and non-governmental groups.

Meeting Germany's climate protection goals--which include a 40% reduction of carbon dioxide emission by 2020 compared with 1990 levels--will be impossible if all of Germany's 17 nuclear reactors "were to be switched off by the end of this decade," Teyssen said.

So true. E.ON has energy interests throughout Europe, though it is headquartered in Dusseldorf.

Some news about Fukushima Daiichi, via NHK:


The operator of the troubled Fukushima Daiichi nuclear plant in northeastern Japan has reassessed its estimates of fuel damage in reactors No.1 to No.3.

Tokyo Electric Power Company on Wednesday announced new estimates of damage after the country's nuclear safety agency questioned the accuracy of the initial assessments. The utility has revised the estimated fuel damage in the No.1 reactor from 70 percent to 55 percent, saying radiation levels were not correct.
TEPCO also says that it acted inappropriately in excluding fuel damage of less than 5 percent in calculating total damage ratios for the No.2 and No.3 reactors.
E.On's Johannes Teyssen. The company color is orange, so you'll often see him posed against this kind of backdrop.

How Nanomaterials Can Make Nuclear Reactors Safer and More Efficient

The following is a guest post from Matt Wald, senior communications advisor at NEI. Follow Matt on Twitter at @MattLWald.

From the batteries in our cell phones to the clothes on our backs, "nanomaterials" that are designed molecule by molecule are working their way into our economy and our lives. Now there’s some promising work on new materials for nuclear reactors.

Reactors are a tough environment. The sub atomic particles that sustain the chain reaction, neutrons, are great for splitting additional uranium atoms, but not all of them hit a uranium atom; some of them end up in various metal components of the reactor. The metal is usually a crystalline structure, meaning it is as orderly as a ladder or a sheet of graph paper, but the neutrons rearrange the atoms, leaving some infinitesimal voids in the structure and some areas of extra density. The components literally grow, getting longer and thicker. The phenomenon is well understood and designers compensate for it with a …

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.

Huh?

The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.


What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…

Why America Needs the MOX Facility

If Isaiah had been a nuclear engineer, he’d have loved this project. And the Trump Administration should too, despite the proposal to eliminate it in the FY 2018 budget.

The project is a massive factory near Aiken, S.C., that will take plutonium from the government’s arsenal and turn it into fuel for civilian power reactors. The plutonium, made by the United States during the Cold War in a competition with the Soviet Union, is now surplus, and the United States and the Russian Federation jointly agreed to reduce their stocks, to reduce the chance of its use in weapons. Over two thousand construction workers, technicians and engineers are at work to enable the transformation.

Carrying Isaiah’s “swords into plowshares” vision into the nuclear field did not originate with plutonium. In 1993, the United States and Russia began a 20-year program to take weapons-grade uranium out of the Russian inventory, dilute it to levels appropriate for civilian power plants, and then use it to produce…
