Educating the Educators

Saturday marked the end of the 2006 Science Teachers’ Workshop, so a report is in order. The Virginia Section of the American Nuclear Society, the Virginia Chapter of the Health Physics Society, and North American Young Generation in Nuclear sponsored this three-day workshop, which was held at Virginia Commonwealth University. Here are my personal reactions.

It was fun! We had about 45 interested, open-minded individuals, and they were appreciative of the effort we had made. I’m hopeful that the workshop will be helpful for their lesson preparations.

It was educational! Naturally, it was educational for the students (the science teachers) but it was also educational for the instructors (the nuclear professionals who presented the workshop). It is often said that the best way to learn a subject is to teach it, and I found that to be true. Preparing a lecture on radioactive waste management required me to brush up on my facts and figures, try to put historical events in perspective, and think about what is of interest to the general public. It also provided an excuse for me to do some simple calculations that I had never done because they were not necessary for my work.

For example, I found that about 22 grams of matter are converted to energy during irradiation of a typical modern PWR fuel assembly, and that about 87% of the fission products decay to stability within one year after that fuel assembly is discharged from the reactor. From my visit to the North Anna Nuclear Information Center, I learned that Dominion’s largest customer is not the Pentagon or the Newport News shipyard, but America Online. It makes you think that conservation-minded Al Gore might need to apologize for inventing the Internet.

It was a lot of work! I did not help with the detailed planning, so it was impressive to see the lectures, breaks, meals, and tours proceed smoothly. The number of details that were considered was staggering.

I would like to express my thanks to the various sponsorsof the event, which ranged from big corporations to small businesses and individuals. Many volunteers also contributed to the workshop at levels of participation from trivial to heroic. My contribution was hardly heroic, but it included preparing a lecture and attending the entire workshop to help out with odd jobs. I hope we will hear some reports from the heroes.

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...
