Yesterday, June 2, 2016, may have marked a watershed moment in the present day history of nuclear power plants in the United States, when two nuclear plants were selected by their owner for shutdown far in advance of their license expiration dates for economic reasons. The fast-moving pace of plants being shut down under similar economic circumstances (unbalanced energy markets that favor other forms of energy to the detriment of nuclear) signals a broken system that must be changed, now.

On May 26, 2016 at precisely 2:16 a.m., what will probably be the final large unit in the Tennessee Valley Authority (TVA) nuclear fleet - Watts Bar Nuclear Plant, Unit 2 - achieved its initial criticality.  This event opens the final chapter of the extended construction history of this unit, and paves way for another gigawatt of generating capacity (in nameplate rating) to be added to TVA's generating portfolio.

Our Friday Matinee for today is the latest of the excellent Vogtle Timeline videos produced by Georgia Power to document the construction progress of Vogtle Units 3 and 4.  The series stands as one of the most thorough video documentations of nuclear plant construction ever filmed, and this latest update is every bit as informative as its predecessors.

Exelon is at a pivotal point where the continued operation of two plants, Quad Cities and Clinton, hinges on the legislative decisions of Springfield, Ill., at the end of May.

Dentists who want to see what is happening behind your teeth, enamel and gums can capture a complete set of dental X-rays in just a few minutes. But imagine if it took 252 films to get the complete picture.

In 1959, a small community in Ohio completed a lobbying effort to bring a modern marvel to town-a nuclear power plant. Piqua, a town of less than 20,000 people, took its place on the broader news map, and set its sights on the stars. The journey would stop short of the citizens' dreams.

Recently, the Nuclear Regulation Authority of Japan announced that Shikoku Electric Power Company's Ikata Unit 3 had cleared the new, three-step process required to restart nuclear plants in Japan.  This latest announcement also came with the closely coupled announcement that Shikoku would permanently close and decommission another nuclear unit, more or less in trade.

This week's Friday Matinee features an update on the construction progress at Plant Vogtle's Units 3 and 4, the new AP1000 units being built in Georgia. This is the First Quarter 2016 update and runs less than ten minutes.

Opportunity. It's the first thing that comes to my mind as I prepare to register for the ANS Annual Meeting in New Orleans.

Yes, it already has, but the truth is so much more boring than the assertions of megadeath, that it generally gets ignored.

Will Davis recently wrote an article on the Cafe: Chernobyl Through the Mist of Decades with a look back, lessons learned,  and life now. But today, April 26, marks the 30 year anniversary of the Chernobyl accident. We encourage everyone to take time to remember Chernobyl, and to review some of the promising information that has been written about the area now, as the world moves forward.

Today's video is brought to us by Third Way, and takes a closer look at the energy sources, and why we need to add nuclear into the energy mix.  Wind and solar are just not able to do it alone and needs nuclear to get the level of electricity we need without destroying our environment.  "So, let's play it smart and develop a mix of low-carbon solutions, because we won't get a second chance to stop climate change." Today,  #EarthDay (and everyday), let's remember to bring good things to our planet.

When Earth Day rolls around on April 22, it marks an opportunity for us to consider our relationship to the natural world, and how we can improve that relationship. The first Earth Day in 1970 signalled the first serious push by ecological activists to influence mainstream public opinion. From its initial beginnings in just the United States, Earth Day has grown until it's now observed in almost 200 countries.

Two significant earthquakes have struck Kumamoto Prefecture in Western Japan within a week, and the Japanese nuclear plant owners and their regulator (the Nuclear Regulation Authority, or NRA) have responded to some reignited fears over nuclear plants in this region by beginning to publish reports and data. The data show that at no point was any of the plants in danger.
