Weekly Update on Fukushima Daiichi

From NEI’s Japan Earthquake update page. Of course, we’ll bring you information during the week, too, if something significant takes place at Fukushima.

Plant Status:

  • Tokyo Electric Power Co. released a roadmap to bring the Fukushima Daiichi plant to a stable condition.
  • Priorities at Fukushima this week continue to be cooling the reactors and spent fuel pools, draining water from the turbine buildings and concrete structures that house piping to reduce radiation levels and containing the spread of radioactive materials.
  • Overall, site radiation dose rates are stabilizing. The most recent radiation readings reported at the plant site gates ranged from 5.7 millirem per hour to 2.6 millirem per hour.
  • Japan’s government has expanded evacuation to selected areas outside the original 12.5-mile zone. Authorities also are barring entry into nine municipalities near the plant.
  • TEPCO released a presentation on April 18 summarizing the impact of the earthquake and the current status of the plants.

Regulatory Issues

  • The NRC continues its inspections of plant sites to review post-Fukushima-related issues.

New NEI Products

  • Video on the future of nuclear energy, featuring Idaho National Laboratory Director John Grossenbacher.
  • Video on the differences in health impacts between Fukushima and Chernobyl, featuring Barbara Hamrick, health physicist at the University of California’s Irvine Medical Center.
  • Video putting the potential of health risks from Fukushima into perspective, also featuring Barbara Hamrick.

Media Highlights

  • An April 21 Associated Press article covered nuclear insurance and an April 19 story detailed early management of the accident.
  • CNN on April 20 covered restricted access to the evacuation zone.
  • A report on the results of a Washington Post-ABC poll released April 20 said that 53 percent of Americans believe nuclear power is safe, but the public opposes construction of new reactors by a 2-to-1 margin.
  • An April 20 Associated Press article focused on projected Fukushima worker health problems.
  • An April 19 New York Times article covered water management at the nuclear power plant site.
  • A Wisconsin State Journal editorial warning that a retreat from nuclear energy is unwise.

The Week Ahead

  • The U.S. Nuclear Regulatory Commission public meeting April 28 to discuss the agency’s response to events at the Fukushima, including station blackout issues.

How Nanomaterials Can Make Nuclear Reactors Safer and More Efficient

The following is a guest post from Matt Wald, senior communications advisor at NEI. Follow Matt on Twitter at @MattLWald.

From the batteries in our cell phones to the clothes on our backs, "nanomaterials" that are designed molecule by molecule are working their way into our economy and our lives. Now there’s some promising work on new materials for nuclear reactors.

Reactors are a tough environment. The sub atomic particles that sustain the chain reaction, neutrons, are great for splitting additional uranium atoms, but not all of them hit a uranium atom; some of them end up in various metal components of the reactor. The metal is usually a crystalline structure, meaning it is as orderly as a ladder or a sheet of graph paper, but the neutrons rearrange the atoms, leaving some infinitesimal voids in the structure and some areas of extra density. The components literally grow, getting longer and thicker. The phenomenon is well understood and designers compensate for it with a …

A Billion Miles Under Nuclear Energy (Updated)

And the winner is…Cassini-Huygens, in triple overtime.

The spaceship conceived in 1982 and launched fifteen years later, will crash into Saturn on September 15, after a mission of 19 years and 355 days, powered by the audacity and technical prowess of scientists and engineers from 17 different countries, and 72 pounds of plutonium.

The mission was so successful that it was extended three times; it was intended to last only until 2008.

Since April, the ship has been continuing to orbit Saturn, swinging through the 1,500-mile gap between the planet and its rings, an area not previously explored. This is a good maneuver for a spaceship nearing the end of its mission, since colliding with a rock could end things early.

Cassini will dive a little deeper and plunge toward Saturn’s surface, where it will transmit data until it burns up in the planet’s atmosphere. The radio signal will arrive here early Friday morning, Eastern time. A NASA video explains.

In the years since Cassini has launc…

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.

Huh?

The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.


What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…
