Byline: the Nuclear Upended Team

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.

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.

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.

Among the many different reactor concepts being investigated in the late 1950s and early 1960s was the idea that the steam produced by a boiling water reactor, which normally goes straight to the turbine building, could be superheated (or have further heat added once it was already steam) by nuclear energy. This would greatly increase the efficiency of the plant, as well as make dry steam at a high pressure that would allow the use of (less expensive) commercially available equipment in the steam plant. Two reactors were built to investigate the idea of performing both processes in essentially the same reactor-one in South Dakota and (perhaps incredibly to today's readers) another of a very different design on the island of Puerto Rico.

Our Friday Matinee this week looks at China's Shidao Bay nuclear plant.  This plant, widely touted as a Gen-IV design, is a bit unusual in that it employs two HTGR's (that's High Temperature Gas cooled Reactors) supplying steam to one turbine generator.  The video gives a good basic look at the plant's design and shows the steady progress being made toward fully operable, commercial HTGR's.

In the administration building of the Chernobyl nuclear power plant, a number of stained glass windows (as seen to the right) recall the optimistic tone of industrial Soviet-era art that can still be viewed today at power plants around the former USSR. That these are well preserved is not the result of a specific effort, but instead because of the essential abandonment of large parts of the facility, and even the entire region, after the most serious nuclear reactor accident in 1986 in history.

August 2012 was hot in Chicago. It was one of those times, while the American Nuclear Society was assembled there for its annual meeting, when the air was so hot and laden with humidity that it palpably hit you when you walked outdoors. All air conditioners, everywhere, were running at their maximum just to keep the buildings in the city habitable.

Two videos are featured this week. The first is a short, brand new (released this morning) video from Georgia Power showing some of the progress at Vogtle Units 3 and 4, set to music.

Today's Matinee is a TEPCO video. A five-year look at the progress, opportunities gained, and the rejuvenation of the area since the day of the terrible earthquake that triggered the devastating tsunami on March 11, 2011 at the Fukushima Daiichi Nuclear Power Plant in Japan.

"It does so much for the everyday citizen that they just don't know. Generating 20% of all the power in the United States, zero carbon emissions, and the jobs and economic activity it creates, it's one of the best kept secrets in the country." - Sean McGarvey, President of North America's Building Trades Unions

Today's Friday Matinee: Bill Gates explains why "we need to pursue many different paths" to carbon-free energy, including the "very promising path" of nuclear. Grab your popcorn and enjoy the video.

This week's ANS Nuclear Cafe Friday Matinee features an update from South Carolina Electric & Gas on "A Year of Progress for V. C. Summer Units 2 and 3."  These two AP1000 units are being built near an existing nuclear unit, and not too far from the former (now decommissioned) site of "The Southeast's First Nuclear Power Plant," the Carolinas-Virginia Tube Reactor.
