Nuclear Matinee: The Mighty Watts Bar FLEX Building

July 25, 2014, 5:57PMANS Nuclear Cafe

If a tornado just happens to come through... flying steel pipes, telephone poles, or even automobiles will be no match for this building. This is the new Watts Bar FLEX building, housing emergency backup equipment like generators and pumps that could be used to replace equipment in case of damage from a natural disaster. Watts Bar will likely be the first nuclear facility in the United States to comply with all the Nuclear Regulatory Commission's post-Fukushima requirements, as the Tennessee Valley Authority works toward licensing for Watts Bar Unit 2 with a target date of beginning commercial operation in December next year.

Near Augusta, Georgia, the first new commercial nuclear power reactors under construction in the United States in 30 years continue to "go vertical."  Take an inside look at the latest from the Vogtle-3 and -4 construction site, including placement of the 1.8 million pound containment vessel bottom head for Unit 4, the cooling tower for Unit 3 surpassing 300 feet, and a very interesting visit to the Port of Savannah where many of the most massive Vogtle components arrive via ship.

Nuclear Video Matinee: Fukushima Health Effects in North America (?)

May 2, 2014, 8:57PMANS Nuclear Cafe

Studies by Janette Sherman and Joseph Mangano purporting to link radiation from Fukushima to health effects in the United States have made for alarming headlines in news outlets on occasion, and have come under fire by critics who charge flawed methodology (for example, What Can We Do About Junk Science and Researchers Trumpet Another Flawed Fukushima Study).

Nuclear Video Matinee: Offshore Nuclear Plants

April 25, 2014, 6:00AMANS Nuclear Cafe

Jacopo Buongiorno of the Massachusetts Institute of Technology discusses some of the advantages of a nuclear reactor concept under development in collaboration with industry and other universities: floating off-shore nuclear power plants, constructed entirely in a shipyard, anchored off the coast, linked to the electric grid via undersea cable. Earthquakes and tsunamis would not be a threat, the ocean would be readily available to serve as a heat sink for reactor cooling, emergency evacuation planning would be a lesser consideration...
