A Big Pump: The Japanese Need It Worse Than We Do

By

pump truck Generosity, American style:

The world's largest concrete pump, deployed at the construction site of the U.S. government's $4.86 billion mixed oxide fuel plant at Savannah River Site, is being moved to Japan in a series of emergency measures to help stabilize the Fukushima reactors.

Why?:

“The bottom line is, the Japanese need this particular unit worse than we do, so we're giving it up," said Jerry Ashmore, whose company, Augusta-based Ashmore Concrete Contractors, Inc., is the concrete supplier for the MOX facility.

Apparently, only two of these pumps exist – the other is in California – and both are going to Japan.

"Our understanding is, they are preparing to go to next phase and it will require a lot of concrete," Ashmore said, noting that the 70-meter pump can move 210 cubic yards of concrete per hour.

I hadn’t read this anywhere else – the pumps can be used for water, too – so Ashmore may be guessing, but that’s okay. He’s allowed.

I should mention that the pumps are German-made and will be transported over to Japan on a special-use Russian plane. A real hands across the water effort.

The Nuclear Regulatory Commission has named six senior managers and staff to its task force for examining the agency’s regulatory requirements, programs, processes, and implementation in light of information from the Fukushima Daiichi site in Japan, following the March 11 earthquake and tsunami.

Here’s what the task force will do, according to the NRC:

“The task force will talk to agency technical experts and gather information to conduct a comprehensive review of the information from the events at the Fukushima Daiichi nuclear complex and make recommendations for any improvements needed to our regulatory system,” Miller said. “We plan to provide our observations, conclusions and recommendations in a written report that will be made public approximately 90 days after we start our review.”

That’s moving very fast. Miller is Charles Miller, director of the NRC’s Office of Federal and State Materials and Environmental Management Programs. The other task force members are from different divisions of the NRC.

A little more:

Areas to be reviewed include station blackout (loss of all A/C power for a reactor), external events that could lead to a prolonged loss of cooling, plant capabilities for preventing or dealing with such circumstances, and emergency preparedness.

The result of this work should be very interesting, though I wonder if the NRC is making informed conclusions about what happened at Fukushima Daiichi or believes enough is known now to do this in an effective way – maybe both.

In any event, recommendations will be offered on July 19. Mark it on your calendar.

When you need a reallly big pump.

Just asking, but surely there must be crane-type "bucket" conveyor belts as I've seen spanning long distances in gravel pits and flour plants that could roughly do the same thing already in Japan?

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...

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"

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...
