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...

Secondly, I do not believe geneticists would support Dr. Caldicott's claim that a change in the DNA sequence of a single cell could cause a mutation resulting in an adverse change to a species (implied if not stated by the letter writer). Living things are constantly evolving, bad mutations are killed off by an organism's immune system. Organisms that suffer really bad mutations usually die before reproducing. One cell does not cause a species to mutate, a change is needed in a population to effect a change to a species. Or at least that was what I learned in History 101 at Monash University in Melbourne, Australia. If there are geneticists out there that can enlighten us as to the latest thinking on this issue I'd really appreciate it.
1. One cell can't cause a mutation. Every cell has its own copy of DNA, and mutations occur on a genetic, not anatomical, level.
2. The likelihood of one cancerous cell becoming a tumor in its lifespan--measured in weeks--is practically zero, if not zero. There needs to be a relatively large number of cells affected. One particle or ray hitting one cell is not going to cause cancer or mutations.
3. The number of types of mutations that radiation could cause is incredibly large. The likelihood of an irrelevant mutation--left-handedness or hair color, for example--is much greater than an adverse effect.
4. We get a lot more radiation from nature than from nuclear power plants, so if these things aren't happening in nature they won't happen with nuclear power plants. People have significant amounts of C-14 in their bodies and these types of things don't happen.
5. Radiation has absolutely no effect--cancers, mutations, green vomit, etc.--until around 10,000 millirem.
