Better Sources on Fukushima than Helen Caldicott

By Eric McErlain
A couple of days ago, a friend of mine passed some news onto me that Dr. Helen Caldicott is hitting the lecture circuit again, this time to talk about the health implications of the incident at Fukushima Daiichi. Her next event will take place tonight in Santa Barbara and will be sponsored by the Nuclear Peace Age Foundation.

Obviously, this blog has a long history debunking Dr. Caldicott's claims about commercial nuclear energy -- one that extends all the way back to 2005 when we disputed her claims about a USEC uranium enrichment facility in Kentucky.

We don't know what Dr. Caldicott will say tonight. However, when it comes to good science about the health effects of radiation, you'd probably be better off watching some video that was shot earlier this month by the Health Physics Society when they hosted a forum on Fukushima. Click here to watch those videos on our SafetyFirst microsite.

One of the individuals you'll see in the videos is Dr. Robert Peter Gale of Imperial College, London. He's worked as a consultant in the aftermath of both Chernobyl and Fukushima. Earlier this month in the LA Times, Dr. Gale wrote the following about the radiation releases at Fukushima and what they mean for the TEPCO employees at the plant as well as the Japanese public:
The kind of radiation was similar to Chernobyl, but about four to 10 times less was released. And there are other important differences. Most of the radiation released (about 80%) was blown offshore by winds, where it was diluted by air and sea. Consequently, exposures received by Fukushima workers and the public are quite low, including among the 20,000 or more workers decommissioning the facility and the approximately 100,000 evacuees. This doesn't mean there will be no future radiation-caused cancers, as some claim. But because there may be so few cancers, it is unlikely any epidemiological investigations will detect an increase in Japan or elsewhere that can be directly attributed to Fukushima.

What do the Fukushima exposures really mean? A rough estimate is that for a 50-year-old male working at the Fukushima nuclear facility, his lifetime risk of cancer might increase from 42% to 42.2%. The magnitude of this increased risk is comparable to the added risk of living in Denver (where background radiation is higher because of the altitude and radionuclides in the Rocky Mountains) versus New York City for 10 to 15 years, or smoking one pack of cigarettes a day for one to two years. The Japanese public will, of course, get far less radiation.

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...
