India Unveils Thorium Reactor

Indian scientists today unveiled a revolutionary design for a thorium breeder reactor (ATBR) that can produce 600 megawatts of electricity for two years with no refueling and practically no control maneuvers:

ATBR is claimed to be far more economical and safer than any power reactor in the world.

Most significantly for India, ATBR does not require natural or enriched uranium which the country is finding difficult to import. It uses thorium -- which India has in plenty -- and only requires plutonium as "seed" to ignite the reactor core initially.

... The uniqueness of the ATBR design is that there is almost a perfect "balance" between fissile depletion and production that allows in-bred U-233 to take part in energy generation thereby extending the core life to two years.

This does not happen in the present-day power reactors because the fissile depletion takes place much faster than production of new fissile ones.

I want to know how much thorium is required to produce 1 Kwh of electricity. I am looking for the commercial figure - one that is in place in a thorium based reactor plant (and not a lab figure).

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...

Wednesday Update

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...

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

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...
