Plug Me In

Back in April, Eric McErlain posted Making the Transition to the Hydrogen Economy in which I first read about hybrid vehicles being modified to further improve fuel efficiency.

Today, CNN's Web site is carrying an interesting story about these "plug-in" hybrid vehicles. These cars, often created by individuals with their own standard hybrids by adding rechargeable batteries, have been shown to get up to 250 mpg.

Dang, I wish someone told me about these when I was commuting 60 miles each way to work (and so I don't lose my credentials as an environmentalist, I'd like to state that I carpooled all seven of those years!).

In any case, the issue of energy sources to power the rechargeable batteries is raised near the end of the article:
Backers of plug-in hybrids acknowledge that the electricity to boost their cars generally comes from fossil fuels that create greenhouse gases, but they say that process still produces far less pollution than oil. They also note that electricity could be generated cleanly from solar power.
While I won't touch the "less pollution than oil" comment with a 12-foot fuel assembly, I will say that perhaps we nuclear advocates should be reaching out to these tech-savvy hybrid-tinkering environmentalists. Many of them are impatient with our country's efforts to reduce dependence on foreign energy sources. Some even malign the push for a hydrogen economy because the benefits will be realized too far into the future. The article states
Instead, Frank said, automakers promise hydrogen-powered vehicles hailed by President Bush and Gov. Arnold Schwarzenegger, even though hydrogen's backers acknowledge the cars won't be widely available for years and would require a vast infrastructure of new fueling stations.

"They'd rather work on something that won't be in their lifetime, and that's this hydrogen economy stuff," Frank said. "They pick this kind of target to get the public off their back, essentially."
With all due respect to these environmentalists who truly put their money and efforts where their mouths are, they have been woefully misled if they believe that solar energy, which currently accounts for less than 1% of the energy needs of this country, will provide a signicant chunk of their inventions' power anytime soon. If they truly want to power their vehicles via clean sources and they want to do it sooner rather than later, nuclear, which currently provides 76% of the nation's emission-free electricity, must play a large part.

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...
