Monday Morning Report

From NEI's Japan Earthquake launch page:

UPDATE AS OF 11:30 A.M. EDT, MONDAY, MARCH 28:
Radiation levels in the seawater near the Fukushima Daiichi nuclear power plant remained high on Monday, but dropped considerably from the levels reported on Sunday. Monday's sampling near the plant's south discharge outlet showed that radioactive iodine levels were 250 times normal, reduced significantly from 1,850 times normal.

Radiation dose rates also remained elevated in the turbine buildings of reactors 1, 2, 3 and 4. Tokyo Electric Power Co. on Monday said that workers had found similarly high radiation levels in water in drainage conduits outside reactors 1 and 2. The company said that rubble at reactor 3 prevented measures from being taken there on Monday.

TEPCO is pumping contaminated water from the basement of the turbine building at reactors 1 and 2 to the main condenser. The company also continued to pump fresh water into reactors 1, 2 and 3, using electrical-driven pumps rather than diesel-powered fire pumps.

Levels of radiation at the plant's main gate ranged from 12.5 millirems per hour to about 20 millirem per hour (125-200 microSieverts/hour). The U.S. Nuclear Regulatory Commission's annual limit for occupational exposure is 5,000 millirem.

For more information about radiation, see NEI's Web page on health and radiation safety.

I don't know if I am totally naive, or late, but cannot a large, hydraulic, robotic, excavating, track type multipurpose crawler be devised to remove the rods and place them into a lead enclosure. Lead sand?
It seems that if we can run robots on Mars, "Opportunity" the technology exists. I know were talking billions of dollars, but to wait 100 yrs?

Fluor Invests in NuScale

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...

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...
