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.

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 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.

1. The Chernobyl Accident Wasn't a Nuclear Explosion. The accident at the Chernobyl nuclear power plant reactor no. 4 in April 1986 did destroy the reactor itself as well as the roof of the reactor building, but the explosive forces involved were, first, a steam explosion inside the complex reactor, followed almost immediately by a hydrogen gas explosion similar to those that occurred at Fukushima. No "nuclear yield" was involved-the forces were, instead, explosive expansion of steam and chemical.

SCANA Updates on V.C. Summer as Westinghouse Reorganizes

April 20, 2017, 6:00AMANS Nuclear Cafe

On April 12, executives of SCANA Corporation and South Carolina Electric & Gas (SCE&G)-two of the owners of the V.C. Summer nuclear plant expansion, which is presently in progress adding two Westinghouse AP1000 units to the older, existing unit on site-delivered an ex parte briefing to the Public Service Commission (PSC) of South Carolina. The information given was quite detailed, but we present the major points here to expand on our coverage of the Westinghouse reorganization.

ANS Friday Nuclear Matinee: Decommissioning in Action

April 14, 2017, 3:15PMANS Nuclear Cafe

ANS Friday Nuclear MatineeThis week's matinee is a documentary of sorts, set to music, showing the decommissioning process undertaken at the former Yankee Atomic Electric plant at Rowe, Massachusetts.  The heavy work to remove the power plant from the site stretched from 2003 to 2007, and much of it is shown in this several section video set to music.  The video is entertaining, but also quite instructive.
