Experts Weigh In: Joseph Mangano Study Hopelessly Flawed

For the nuclear industry, safety is the top priority, and it goes to great lengths to minimize radiation exposure to the public and employees. So exhaustive are these measures that nuclear power plants only account for .1% of the annual radiation that a typical American is exposed to. Nearly half come from medical exposures.

Yet Joseph Mangano seems intent on repeatedly and falsely stating otherwise. Most recently, Mangano published a study that suggests a correlation exists between the closing of Rancho Seco and the decline in cancer rates in the surrounding area. We responded by reminding the media to consider Mangano's lack of credibility when it comes to "scientific findings" before distributing the study to their readers. This week, local Pennsylvania experts came to the same conclusion about his bogus work. An especially compelling statement comes from the state's director of the Bureau of Radiation Protection:

David J. Allard, director of the Pennsylvania Dept. of Environmental Protection’s Bureau of Radiation Protection, oversees nine active nuclear power plants on five sites throughout the state. DEP also oversees licensing for medical, academic, industrial type of sources of radiation including nearly 30,000 pieces of x-ray equipment in facilities, half of which are used by dentists.

“The technical reality with these nuclear power plants is that under the federal regulations, Title 10, Part 50, in the code of federal regulations, these power plants can’t emit liquid and airborne radiation that cause greater than three millirem of radiation,” says Allard.

“We see lots of background (radiation) and it’s only when you have Chernobyl or Fukushima where you actually see material on our samples other than the natural background and some residual fallout from the 50s and 60s. We monitor this and quite honestly at those kinds of levels, it’s really, really difficult to measure.”

According to Allard, radon, chemical exposures, genetics and lifestyles may have more impact on the prevalence of cancer rates.

“The problem is that correlation does not mean causation just because people live next to a power plant,” he says. “People are moving in and out. There are other major sources of radiation exposure that the public gets that really swamp whatever little radiation does come from the nuclear plant. The big one is the medical screenings…In these studies, whether by the NRC or Mr. Mangano, you have to control for those other sources of exposure.”

If his word isn't good enough, check out our past coverage of Mangano's sloppy research (a generous phrase for his work). The fact remains that America's nuclear plants are proven to be safe and continue to operate according to rigorous and comprehensive safety standards.

Activists' Claims Distort Facts about Advanced Reactor Design

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?

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?

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...
