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.

From NEI’s Japan micro-site: NRC, Industry Concur on Many Post-Fukushima Actions Industry/Regulatory/Political Issues • There is a “great deal of alignment” between the U.S. Nuclear Regulatory Commission and the industry on initial steps to take at America’s nuclear energy facilities in response to the nuclear accident in Japan, Charles Pardee, the chief operating officer of Exelon Generation Co., said at an agency briefing today. The briefing gave stakeholders an opportunity to discuss staff recommendations for near-term actions the agency may take at U.S. facilities. PowerPoint slides from the meeting are on the NRC website. • The International Atomic Energy Agency board has approved a plan that calls for inspectors to evaluate reactor safety at nuclear energy facilities every three years. Governments may opt out of having their country’s facilities inspected. Also approved were plans to maintain a rapid response team of experts ready to assist facility operators recoverin...

Fluor Invests in NuScale

By
You know, it’s kind of sad that no one is willing to invest in nuclear energy anymore. Wait, what? NuScale Power celebrated the news of its company-saving $30 million investment from Fluor Corp. Thursday morning with a press conference in Washington, D.C. Fluor is a design, engineering and construction company involved with some 20 plants in the 70s and 80s, but it has not held interest in a nuclear energy company until now. Fluor, which has deep roots in the nuclear industry, is betting big on small-scale nuclear energy with its NuScale investment. "It's become a serious contender in the last decade or so," John Hopkins, [Fluor’s group president in charge of new ventures], said. And that brings us to NuScale, which had run into some dark days – maybe not as dark as, say, Solyndra, but dire enough : Earlier this year, the Securities Exchange Commission filed an action against NuScale's lead investor, The Michael Kenwood Group. The firm "misap...

Nuclear Utility Moves Up in Credit Ratings, Bank is "Comfortable with Nuclear Strategy"

By
Some positive signs that nuclear utilities can continue to receive positive ratings even while they finance new nuclear plants for the first time in decades: Wells Fargo upgrades SCANA to Outperform from Market Perform Wells analyst says, "YTD, SCG shares have underperformed the Regulated Electrics (total return +2% vs. +9%). Shares trade at 11.3X our 10E EPS, a modest discount to the peer group median of 11.8X. We view the valuation as attractive given a comparatively constructive regulatory environment and potential for above-average long-term EPS growth prospects ... Comfortable with Nuclear Strategy. SCG plans to participate in the development of two regulated nuclear units at a cost of $6.3B, raising legitimate concerns regarding financing and construction. We have carefully considered the risks and are comfortable with SCG’s strategy based on a highly constructive political & regulatory environment, manageable financing needs stretched out over 10 years, strong partners...
