This week's ANS Nuclear Cafe Friday Matinee is the very latest video update from Tokyo Electric Power Company on the conditions at 1F -- that is to say, "First Fukushima" or the Fukushima Daiichi nuclear power station.

There have been a number of significant and/or interesting developments in the nuclear energy field recently, with large light-water reactor business taking the fore.  Here are some highlights:

"Some recent work by E. Fermi and L. Szilard, which has been communicated to me in manuscript, leads me to expect that the element Uranium may be turned into a new and important source of energy in the immediate future." - Albert Einstein, letter to President  Franklin D. Roosevelt, August 2, 1939

When you hear the friendly voice of Joe Washington, you know that it's time for another in the excellent series of "Vogtle Timeline" videos presented by Georgia Power.  This most recent update covers some important ground - namely, the change in construction arrangements following Westinghouse's bankruptcy and how the project goes on from that point.  Not only is physical progress at the plant site displayed, but community outreach and impact are also shown in this well produced video.

"There's no one I'd rather go into battle with," said ANS President Bob Coward to a packed Opening Plenary audience this morning, "than nuclear professionals," in reference to the stated purpose of ANS in advancing nuclear technologies.  Coward's very first remarks set the tone for a speech that was remarkably hopeful and bright given the recent blows that nuclear energy has suffered here in the United States.

One of the things that's important to consider this week - National Clean Energy Week - is whether or not energy sources we depend upon are actually clean.  While we think of solar and wind energy as being pretty clean, we are also reminded that they are not reliable, and they do experience periods of time when they just don't work.  What we use to fill in that power gap is from sources we can control, independent of weather or time of day. These are sources we call "dispatchable" generating sources, because we can dispatch them and expect they'll answer the call to provide power.

Hurricane Irma shocked the country this week with images of wind and water that haven't been seen in some time along the hurricane-wary coastlines of the United States. Although people in those regions always have preparation for these storms somewhere in their minds, the two Florida Power & Light (FPL) nuclear plants-both of which powered through the hurricane-had both a background of design and preparedness to stand on as well as some recent, last-minute preparations.

In a world fraught with loud, anti-nuclear voices, including a recent satirical news show that had a bit on nuclear waste, I've been pondering ideas that would provide a media platform to help counter the attacks on nuclear. While I am still a penniless grad student who lacks the budget of a weekly HBO nightly show, I believe I may have found a compromise. Starting today, Friday, September 1, 2017, I will be launching the bi-weekly podcast RadioNuclear.

In June, Bob Coward became the 63rd president of the American Nuclear Society. Watch this short introduction video where Bob talks about his career, his thoughts on the future of nuclear, and how it fits into the needs of the world.

Editors note: Today's video is second in a special series filmed in June at the American Nuclear Society's Annual Meeting held in San Francisco, Calif. this past June.

The 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.

Our ANS Nuclear Cafe "Friday Nuclear Matinee" feature this week is a brand new video produced by the IAEA (International Atomic Energy Agency) entitled "What is the Future of Nuclear Energy?"  This fact-filled three-minute video is a good primer for the future of nuclear power.  We hope you enjoy it!

Reports out of China emerged earlier this week that Sanmen Unit 1, the first Westinghouse AP1000 unit expected to start up, had "been commissioned."  These reports quoted an official speaking at a professional conference.

More than the usual number of nuclear energy-related news items have come to the fore this week, so we'll touch on each significant development and provide links for further reading.

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.
