July 1959: Savannah Afloat!

July 31, 2017, 11:00AMANS Nuclear Cafe

NS Savannah AtomThe last half of the 1950s was a time of great promise for the concept of atomic-powered commercial ships. The idea was given real political momentum (which it very much needed) in 1955 when President Eisenhower formally proposed construction of such a ship by the United States. In July 1956, Congress passed Public Law 848, authorizing the actual engineering and construction of the ship.

The New Great Compromise: Nuclear Energy’s Broad Appeal

July 11, 2017, 5:21PMANS Nuclear CafeDoug Hardtmayer

Whenever I turn on the news and hear how America should generate its electric power, hardly any "expert" cites nuclear energy. Energy discussions are especially prominent now, since the United States decided to pull out of the Paris climate agreement. What is so striking to me is that nuclear is almost never talked about, and when it is, it's normally an afterthought to other sources of energy. America's largest source of clean power is nuclear, which makes up roughly 20 percent of all power generation, and it should take a more prominent role. This got me wondering, why isn't nuclear talked about more as a solution? As a nuclear engineer, my opinion, albeit a bit biased, is that we need nuclear energy in our energy mix.

Belief in Science Trumps Global Deals

Science hasn't always been his strongest suit, but he has grown up to be a businessman who, despite his lack of diplomatic conduct, has managed to successfully negotiate the most challenging deal of all- becoming president of the largest economy in the world. Why then, is this businessman's decision to pull out of an environment deal met with harsh criticism and distrust?

South Korea Reverses Course

In a stunning but not wholly unexpected move, newly elected South Korean president Moon Jae-In announced during a ceremony marking the final shutdown of Kori Unit 1 that future nuclear power plants in South Korea will be cancelled and that the country will begin to shift toward renewables for its future energy needs-backed by natural gas.

The spirit of hope, even in the face of what ANS President Andy Klein acknowledges as "tough times" for nuclear energy, has made itself more than evident at the 2017 Annual Meeting.  The spirit can be found everywhere, and it was further promoted on Monday morning as a new style of presentation for the opening plenary -- itself innovative -- was delivered to an excited audience.

Announcing the ANS Nuclear Grand Challenges

nuclear grand challenge logo-sqAs I considered how ANS could best forward the interests of nuclear professionals during my term as president (June 2016-June 2017), I was compelled by the idea of identifying the technical nuclear challenges that need to be resolved by 2030 in order to help solve some of the economic, sociological, or political issues that we face as a society.

1955: First Sale of Atomic Electricity

The now-obscure and thick "Atoms for Peace Manual" published in 1955 by the U.S. Government Printing Office (and presented by Senator Alexander Wiley) contains, near its end, a curious and also now-obscure event in atomic energy history:  The first commercial sale of atomic-generated electricity.  And thereby hangs a tale.
