TEPCO to Build Iron Wall to Contain Radioactive Water

Plant Status

• Tokyo Electric Power Co. plans to build an “iron wall” between the Fukushima Daiichi nuclear energy facility and the ocean to keep radioactive water out of the sea. Thousands of 24-yard-long iron pipes will be sunk into the earth, extending to below the sea bed, to create a wall around the water intakes for reactors 1-4. Construction of the 875-yard wall is expected to begin by the end of the year and be complete in about two years.

Industry/Regulatory/Political Issues

• The Japan Agriculture, Forestry and Fisheries Ministry has been conducting experiments since May on reducing radiation levels in rice fields near Fukushima Daiichi. In one test, workers have scraped contaminated topsoil from dry paddies. In another, soil has been stirred in water-filled paddies and then removed. Both methods have reduced radiation levels to below government safety levels.

New Products

• New talking points summarize key topics from NEI’s comment letter to the U.S. Nuclear Regulatory Commission on proposed near-term actions at U.S. reactors following the Fukushima Daiichi accident. Another set of talking points discusses localized spikes of radiation in areas near the nuclear facility. More talking points address the NRC's approach toward plant seismic studies, which respond to misconstrued media reports on these studies.

Media Highlights

• Tokyo Electric Power Co. will put $30 billion into a new entity established to help the utility compensate individuals and businesses claiming damages caused by the Fukushima Daiichi accident, the Japan Economic Newswire reported. The fund also will receive $91 million from the government and $91 million from 11 other utility companies.

• Japanese citizens are debating the country’s energy future following the accident at Fukushima Daiichi. It is a dilemma for a country that lacks natural resources and has relied heavily on nuclear energy, NPR reports.

Upcoming Events

• A public Sept. 8 NRC Advisory Committee on Reactor Safeguards meeting will include a review the agency’s near-term task force report on the events at Fukushima.

• The NRC commissioners will be briefed on short-term actions recommended in its Japan task force report in a public meeting Sept. 14. The meeting will be webcast.

• The NRC commissioners will be briefed on prioritization of recommendations from its Japan task force in a public meeting Oct. 11. The briefing will be webcast.

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...
