US Nuclear Performance – October 2010

It’s been awhile since we’ve highlighted our monthly nuclear performance report on the blog. Most of the time the nuclear units hum along at their usual pace so there’s not much to report. But worth mentioning from the latest issue is that nuclear generation in the US in 2010 could break its previous 2007 record:

Year-to-date 2010 nuclear generation is 0.4% higher than the same period in 2009. For 2010, nuclear generation was 670.0 billion kilowatt-hours compared to 667.2 bkWh for the same period in 2009 and 669.5 bkWh in 2007 (the record year for nuclear generation).

For October 2010, nuclear generation was 61.8 billion kilowatt-hours compared to 57.7 billion kWh in October 2009. The average capacity factor for October 2010 was 82.5% compared to 77.0% in October 2009.

For the 2010 fall refueling outage season, 15 units completed refueling while another eight are still shut down. Twenty-three nuclear reactors are expected to refuel during fall 2010 compared to 33 in fall 2009.

Average refueling outage durations for PWRs during fall 2010 (12 units) was 39 days compared to 29 days during the same period for BWRs (3 units).

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...
