Quick Hits: At Indian Point, Three Plants, The German Psyche

CNN’s Alan Chernoff goes into a nuclear plant – New York’s Indian Point, in this case – and nothing falls over on him and he doesn’t topple into the used fuel pool (which he takes a look at). In fact, he finds a spotless, well run industrial structure. Oh, and extremely secure.

Useful type of story for reporters to be doing – folks are probably pretty curious about the inside of a plant right about now.

At a House hearing, NRC Commissioner Gragory Jaczko loosely identified three nuclear plants the commission believes need further oversight:

Three U.S. nuclear power plants need increased oversight from federal regulators because of safety problems or unplanned shutdowns, the Nuclear Regulatory Commission said Thursday, although officials said all are operating safely.

NRC Chairman Gregory Jaczko said the three plants — in South Carolina (H.B Robinson), Kansas (Wolf Creek) and Nebraska (Fort Calhoun)— "are the plants we are most concerned about" among the 65 U.S. nuclear power plants in 31 states.

Jaczko did not say what issues require the extra oversight:

"The NRC felt the three required significant additional oversight but continue to operate safely," said Scott Burnell, an agency spokesman.

The story quite correctly notes that there are four levels of oversight and these plants fall into the second. The third and fourth levels would be far more serious for the plants. Tellingly, Jaczko initially told the House committee that six reactors were on the list, but three of them, at the Oconee plant, had resolved all issues and were taken off the list.

Sarah Sloat has a go at German kookiness about nuclear energy:

So then, what’s the source of this “special sensitivity?” It’s hard for the Germans themselves to pin down. Some see its root in German romanticism of the 19^th century, the idealization of nature seen, for example, in the landscapes of Casper David Friedrich.

Others attribute it to the national character. “It’s all psychological; it’s typical German nervousness,” said one. Characteristics like “cautiousness” and “risk-aversion” also come up.

Sloat decides its all about Chernobyl, but I liked these better. Risk-aversion! It’s a wonder Germans drive cars or get on a plane – far riskier than having a nuclear energy plant in the neighborhood.

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...

How many nuclear plants does it take to meet the world's energy needs?

Several weeks ago Joshua Pearce at Clarion University in Pennsylvania released a study titled “ Thermodynamic limitations to nuclear energy deployment as a greenhouse gas mitigation technology .” In the study he stated... nuclear energy production would have to increase by 10.5% per year from 2010 to 2050 to both replace fossil-fuel-energy use and meet the future energy demands. This line, of course, made the headlines and has been picked up by several outlets and blogs . When looking into his calculations for this statement, he made one assumption error that overstated the above sentence by nearly a factor of three. Page 121, Section 4.1 of the study states: Richard Smalley pointed out that in 2004, the global economy consumed the equivalent of 220 million barrels of oil per day, which converted into electricity terms is the equivalent of 14.5 TeraWatts (TW), or 14,500,000 MegaWatts (MW) (2005). … With a nuclear plant having about 1000 MW (1 GW) of capacity, we would need 14,500...

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...
