Climate Change and Nuclear Energy: We Need to Talk

July 25, 2012, 6:00AMANS Nuclear CafeSuzy Hobbs Baker

During my undergraduate studies in art school, I created a body of artwork about micro-organisms. After taking my two required biology courses, I was completely obsessed with cyano-bacteria and diatoms (they are still a central theme in my home décor). Learning that every cell in my body has mitochondrial RNA identical to these ancient life forms floored me, and made me feel completely connected to the planet and all of the other life on it in a very concrete way.

ANS Friday Matinee: Eric Loewen at Arthur M. Sackler Colloquium

July 20, 2012, 6:00AMANS Nuclear Cafe

The Arthur M. Sackler Colloquia addresses scientific topics of broad and current interest that cut across the boundaries of traditional disciplines. "The Science of Science Communication" was a Sackler Colloquium interdisciplinary scientific meeting held at the National Academy of Sciences in Washington, D.C., on May 21-22, 2012. At this meeting, American Nuclear Society Past President Dr. Eric Loewen addressed the other "three R's" of [nuclear] education:  Radiation, Reactors, and Residuals.

Court upholds EPA greenhouse gas regulations

July 18, 2012, 6:00AMANS Nuclear CafeJim Hopf

In a strongly worded unanimous decision, a federal appeals court recently upheld the Environmental Protection Agency's authority to regulate greenhouse gas emissions, as well as the EPA's "endangerment finding" that holds that those gases present a threat to human health and welfare. The court also upheld the EPA's authority to "tailor" such regulations as it sees fit, which will allow the EPA to exempt small sources of emissions and focus its regulations on large emitters (which would be more practical, and a less expensive way of reducing emissions). The court stated that the EPA's interpretation of the Clean Air Act (CAA) requirements was "unambiguously correct" and that its proposed rules were neither capricious nor arbitrary.

The passing of the gavel

July 16, 2012, 6:00AMANS Nuclear Cafe

Following the American Nuclear Society Board of Directors meeting on Thursday, June 28, Michael Corradini officially became ANS President and Eric Loewen transitioned to ANS Immediate Past President. ANS President Corradini presented a commemorative gavel to the ANS Immediate Past President at the conclusion of Dr. Loewen's term.

Low level radiation and LNT examined at Chicago ANS meeting

July 11, 2012, 6:00AMANS Nuclear CafeGeorge Stanford

At the ANS Annual Meeting in Chicago held June 24-28, I attended the "President's Special Session on Low Level Radiation and Its Implications for Fukushima Recovery," and also the follow-on panel "Health Effects of Low-Level Radiation." The two sessions together could well have been subtitled "The Tragedy of LNT." In case you've forgotten, LNT stands for "Linear No Threshold"-the popular misconception that radiation risk is proportional to dose all the way down to zero.

Some Big Changes in Vermont

July 10, 2012, 6:00AMANS Nuclear CafeHoward Shaffer

Since the previous View from Vermont posted June 12, courts have issued several decisions that will have a major effect on nuclear power nationally, and on the Vermont Yankee nuclear power plant in particular. The Supreme Court ruling on the Affordable Health Care Act has moved attention from these important federal court decisions, which otherwise would have received more publicity (outside of Vermont).

NASA's Roadmap to the Nuclear Thermal Rocket

July 9, 2012, 6:00AMANS Nuclear CafeWes Deason

It is certainly exciting times for NASA and the space nuclear community, as physical testing of nuclear thermal rockets (NTRs) and associated components has begun at NASA and the Department of Energy laboratories across the country. Nuclear thermal propulsion, as discussed in a previous article, is just one form of nuclear propulsion with extensive research behind it, and the only form with an extensive testing background. Near-term efforts by NASA will focus on preparation for ground and flight tests of a scalable Nuclear Thermal Rocket around 2020. However, the larger purpose of the recently restarted testing track is to develop an engine for manned travel to an asteroid, and eventually to our neighboring planet, Mars.

Sharon Kerrick Receives American Nuclear Society Presidential Citation

American Nuclear Society (ANS) President Eric Loewen, PhD, presented ANS Outreach Department Director Sharon Kerrick (retired) with a Presidential Citation in recognition of her outstanding career of service to the American Nuclear Society.  Kerrick received her award during the ANS President's Special Session at the ANS Annual Conference: "Nuclear Science and Technology: Managing the Global Impact of Economic and Natural Events," recently held in Chicago, Illinois.

Implications of improved radiation protection standards for Fukushima evacuees

The American Nuclear Society's annual meeting for 2012 included a President's Special Session titled Low-Level Radiation & Its Implications for Fukushima Recovery (Warning-the link leads to a 54 MB, 208 page PDF full of disruptive information that might change your opinion on the benefits of spending billions of dollars every year to keep radiation doses as low as unreasonably achievable).
