GE Submits ESBWR to NRC for Design Approval

By Eric McErlain
From yesterday's wire:
GE Energy's nuclear business has reached a major milestone in the development of its new reactor design - the economic simplified boiling water reactor (ESBWR) - by formally submitting its Design Certification application to the U.S. Nuclear Regulatory Commission.

GE delivered its 19-chapter, 7,500-page application package to the NRC in Washington on August 24. The submission, which represents the culmination of 150,000 man-hours of design work over a 10-year period, should lead to the Final Design Approval of the ESBWR by late 2006, followed immediately by Design Certification.

The 1,500-megawatt ESBWR is a Generation III+ reactor design because of its design simplicity and passive safety features. It depends on fewer "active" mechanical systems, with associated pumps and valves, and instead relies on more reliable "passive" systems that utilize natural forces, including natural circulation and gravity.

The ESBWR is the only reactor that fully relies on natural circulation for normal plant operations as well as passive safety systems, thus making it the most advanced, passive Generation III+ reactor to be presented to the NRC for final approval.

"Submitting the ESBWR for formal design approval represents a truly significant accomplishment by GE Energy's engineering team that worked on this project, especially given the magnitude of the document and complex technical challenges," said Andy White, president and CEO of GE's nuclear business. "Many of our customers are already aware that the ESBWR is an extremely elegant design that offers all the benefits they require: safety, reliability and operational flexibility delivered with the most cost-effective advanced reactor design we can provide - one that is based on GE's proven BWR technology."
Back in May, GE inked an agreement with NuStart Energy to seek the license in connection with the consortium's efforts to site and build a new nuclear reactor.

Activists' Claims Distort Facts about Advanced Reactor Design

By
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?

By
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?

By
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...
