Small Reactor Week

Last Wednesday, CSIS hosted Scaling Down Reactors: A Different Model for Nuclear Energy, and has made available the speaker bios and presentations along with audio of the event. Their brief overview of this new & growing field:
Several companies and research teams are now pioneering smaller reactor designs that could present a unique set of characteristics and benefits desirable to domestic utilities as well as other nations interested in nuclear energy. Ranging in size and technology, smaller reactors could offer different capital cost structures, the possibility of modular designs, and new operational and safety characteristics. Internationally, these reactors may also introduce important considerations for grid compatibility and nonproliferation efforts.
Then, NRC held a workshop Thursday and Friday, Small- and Medium-Sized Reactors, at which Chairman Greg Jaczko spoke. The presenters’ slides are here, except for DOE’s presentation.

NEI was represented by Paul Genoa, who articulated three trends: the need for electricity to drive economic development; the growing connection between economic and energy security; and mounting concern about global warming. Paul told the gathering that small reactors hold a sweet spot where these matters intersect.

Many of these speakers and industry representatives had also spoken at a Hill briefing a couple weeks ago, There's an App for That, organized by the Foundation for Nuclear Studies.

Atomic Insights just published a superb, textured article on NRC’s workshop, noting among other things that "[t]he meeting was surprisingly well attended - there were more than 100 people there. The NRC had to move in extra chairs; it was initially a standing room only affair."

Interpreting one of Chairman Jaczko's themes for the non-government experts among us, Rod's article reads:
Jaczko . . . also recognizes that the change is ultimately a political decision that requires compromises and negotiations that are not in the core competency or even the legislative mandate of his regulatory agency. Inside the government, people often talk about the concept of breaking down organizational barriers that we call silos, but most are also quite reluctant to even recommend actions that are 'outside of our swim lane.' Jaczko has told the people who believe strongly in the value of [these] reactors . . . that he feels their pain and will not oppose a fair solution . . .

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...
