Nuclear Energy Industry Transitions

Mike Coyle is Exelon Nuclear’s new vice president of mid-Atlantic operations. He previously served as NEI’s vice president of operations.

Progress Energy has announced several management changes. Jeffrey Lyash will be president and CEO of Progress Energy Florida, effective June 1. He will replace the retiring H. William Habermeyer Jr. Don Davis, executive vice president of diversified operations, will retire April 14. Paula Sims, currently vice president of fossil generation, will replace Davis and senior vice president. Charlie Gates, coal-fired power plant manager in the Carolinas and general manager of Progress Energy’s three fossil plant regions, will replace Sims.

The Nuclear Regulatory Commission has named J. Sam Armijo, Ph.D., to its Advisory Committee on Reactor Safeguards. Armijo is an adjunct professor of materials science and engineering at the University of Nevada, Reno.

Alexander “Andy” Karsner has been sworn in as the Department of Energy’s assistant secretary of energy efficiency and renewable energy. He had been confirmed March 16 by unanimous consent of the Senate. Karsner joins DOE from Enercorp LLC, where he was managing director.

Russia’s Rosenergoatom has named Sergei Alexandrovich Obozov its acting director general and Alexander Markovich Lokshin first deputy director general. Stanislav Ivanovich Antipov has been appointed adviser.

Activists' Claims Distort Facts about Advanced Reactor Design

Below is from our rapid response team . Yesterday, regional anti-nuclear organizations asked federal nuclear energy regulators to launch an investigation into what it claims are “newly identified flaws” in Westinghouse’s advanced reactor design, the AP1000. During a teleconference releasing a report on the subject, participants urged the Nuclear Regulatory Commission to suspend license reviews of proposed AP1000 reactors. In its news release, even the groups making these allegations provide conflicting information on its findings. In one instance, the groups cite “dozens of corrosion holes” at reactor vessels and in another says that eight holes have been documented. In all cases, there is another containment mechanism that would provide a barrier to radiation release. Below, we examine why these claims are unwarranted and why the AP1000 design certification process should continue as designated by the NRC. Myth: In the AP1000 reactor design, the gap between the shield bu...

What Happens During a Refueling Outage?

You may have noticed over the past few weeks that a number of nuclear plants are shut down for refueling outages or are resuming operations after just returning from one. This type of routine outage usually occurs in the spring or fall when electricity demand is low so that nuclear reactors can replace about one-third of the spent fuel rods with new fuel and conduct other routine maintenance and repairs at the plant. To get a better sense of how refueling works at a nuclear energy facility, I spoke with Marcus Nichol, NEI’s senior project manager for used fuel storage and transportation, and asked him to explain the basics. Why does a nuclear plant need to replace one-third of its fuel? Nichol: The main purpose of a refueling outage is to replace older fuel that is depleted—meaning it can no longer efficiently produce energy from nuclear fission reactions—with new fuel. This “used fuel” has typically been used in the reactor for four-and-a-half to six years before it is pe...

How Much Land Does Nuclear, Wind and Solar Really Need?

Not too long ago, we reviewed a report that looked at nuclear energy (and other energy sources) as biodiversity agents. This had to do, in part, with the amount of land a facility needs to function. Nuclear energy and fossil fuel plants use relatively little, wind farms and solar arrays quite a lot of land . Based on an objective and transparent analysis of our sustainable energy choices, we have come to the evidence-based conclusion that nuclear energy is a good option for biodiversity conservation (and society in general) and that other alternatives to fossil fuels should be subjected to the same cost–benefit analyses (in terms of biodiversity and climate outcomes, as well as sociopolitical imperatives) before accepting or dismissing them. Writer Barry Brook, who collected 75 scientists to endorse his paper, is interested in land use as it impacts flora and fauna. Biodiversity concerns do not get as much play as they might – and, when they do, it annoys many when land is withdraw...
