Around the Energy Blogs

It occurred to me over the weekend that we haven't been visiting a number of our neighbors in the energy blogosphere, and it's far past time that we corrected that oversight.

The Ambivalent Engineer has a question about nuclear fuel:

So what is the burnup limit, and do operators currently burn fuel all the way to the limit?

Rod Adams has the answer.

Our friend Stewart Peterson has moved Nuclear is our Future to a new address. Please update your bookmarks.

Thanks to some new legislation working its way through Congress, the Cape Wing Project might be in trouble. The Watthead is concerned.

The Guardian has published another dubious poll. Randall Parker has his doubts too.

Those of you interested in environmentally responsible transportation might be cheered to discover that the ZAP is coming to America:

After a number of false starts ZAP (PCX:ZP) now claims it is about to start selling the Smart Car, the fuel-efficient micro-car from Europe. ZAP is preparing to distribute the cars along with other models through a dealer network it is forming in the U.S. that specializes in advanced automotive technologies.

Orion VII series-hybrid buses operated by New York City Transit (NYCT) on the city'’s most severe duty cycles achieved up to 45% better fuel economy than diesel buses and 100% improvement compared to comparable natural gas buses on an energy-equivalent basis, according to the results of a study released by the National Renewable Energy Laboratory (NREL).

Anything that diverts natural gas to other uses sounds good to me. Click here for the numbers.

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...
