Another Blogger for Nuclear Energy

Physical Insights and Atomic Insights already beat me to the punch but we'll still do the introduction. Meet Finrod over at Channelling the Strong Force. His About this blog piece is very thought-provoking, make sure to check it out:

We exist in a sea of electromagnetic force, and are for the most part utterly subject to its dictates. One other force makes itself blatantly known in the course of our mundane activities, namely gravitation, but electromagnetism packs far more power in its punch. It takes a mass the magnitude of Earth to make us weigh ten Newtons to the kilogram, but with a simple rearrangement in the structure of a vanishingly, ridiculously tiny portion of Earth’s mass, we can override the gravitational force of this entire planet, and stand on two feet (by burning sugar in our cells) … or fly to the other side of it in a 747 (by burning avgas in a jet engine).

...

The images of the early nuclear age have a certain amount of baggage which we need to move beyond to make informed choices for the future. This blog is my humble attempt to encourage people to make that move.

Welcome for the third time!

Correction: Welcome for the fourth time! My bad Dan. :)

The fifth time if you count the quick mention Rod gave at the conclusion of Atomic Show 111. What with all this exposure, I'd better get my finger out and put together some more material. Hopefully some will find it useful and/or interesting. Thanks for the mention.

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...
