Gridwatch: What Just Happened Five Minutes Ago?

Happy new year, my fellow carbon dioxide-emitter. Of course we do not contribute significantly by any measure to the carbon emissions plaguing our atmosphere. So, what does contribute so heavily to the increasing carbon content in the air? Let's find out.
A Change of Plans at Brookwood

By the middle of the 1960's, Robert Emmett Ginna had already spent over a decade taking part in, and in no small part championing, the development of what we would today call advanced reactors. His efforts contributed to the development of breeder and high temperature reactors, yet when it came time for his own utility to construct a nuclear plant, it made a sudden reversal to construct a very conventional pressurized water design.
NRC's Work in Progress on Public Meetings
December 29, 2016, 3:02AMANS Nuclear Cafe
On February 19, 2015, a Nuclear Regulatory Commission public meeting held in Brattleboro, Vt., descended into chaos. Protesters who were bent on disrupting the proceedings bullied and threatened people who wanted to speak at the meeting. The disrupters' tactics included shouting at speakers, interrupting their remarks, and making verbal threats against those who sought to speak in support of either the NRC's proposed action or the utility that was the subject of the meeting.

On Monday, December 19, the Japanese government announced that it was finally giving up on the decades-old Monju fast-reactor project. Troubled in recent years with safety problems and allegations that the Japan Atomic Energy Agency (the operator) has been unable to find solutions for the problems. The Monju facility had been widely considered as under threat for some time.
Shippingport Reaches Criticality for the First Time

Which came first: the nuclear power plant or the nuclear-powered submarine? It sounds like a chicken-and-the-egg question, but the answer is quite simple: the nuclear-powered submarine.

A statement made this week by the President of Iran has gained some hold on the press, and while it sounds like an interesting and for some potentially threatening development, it more than likely won't happen any time soon.
Week in Review

A number of significant news items made recent headlines relating to nuclear energy. Here is your week in review with an analysis and links.
Nuclear History and ANS
December 6, 2016, 8:17PMANS Nuclear Cafe
I am pleased and proud to report that the American Nuclear Society (ANS) recently completed a project to post brief bios of all 61 ANS past presidents (plus the current president). Pleased, because many of the past presidents were icons in the early development of nuclear power, or played key roles in the evolution and growth of the nuclear industry, and it is wonderful to have so many of their stories in one place. Proud, because I had a role in helping solicit biographical information from the living past presidents and in searching for information on the deceased past presidents. But let me quickly add that this was not a solo effort. It involved the contributions of many people, both other ANS past presidents, ANS staff and others I contacted in the course of my research.
Anniversary of First Man Made Criticality - December 2, 1942

A Small But Nagging Point

 SIR (Submarine Intermediate Reactor) Naval Prototype Plant rolled into containment sphere at West Milton New York; March 20, 1954. From brochure "The Seawolf Story" in Will Davis library.
We're coming up on another anniversary of the startup of the Shippingport Atomic Power Station in early December. That plant was more or less a Navy plant (at least in terms of the NSSS or Nuclear Steam Supply System) built not for powering ships but instead for powering businesses and homes. The move to get that done was rapid and fluid - and now there's maybe a hint of evidence that it could have been a returned favor to Admiral Rickover.

Historic Idaho Reactors Detailed at ANS Winter Meeting

 Installation of SPERT-II reactor vessel at National Reactor Testing Station, now Idaho National Laboratory. From IDO-16050, published 1959, in Will Davis library.
The history and lore surrounding the dozens of reactors constructed and operated at the Idaho National Laboratory could fill a book - and has filled at least one whole book and parts of many others. Today, at the American Nuclear Society's 2016 Winter Meeting a unique presentation was given in the early afternoon by Harold McFarlane, who retired after 44 years working with Argonne National Laboratory (which operated a number of the reactors built in Idaho.)
Advancing Nuclear: Paths to the Future
November 8, 2016, 2:41AMANS Nuclear Cafe
"How do we move nuclear energy into the future?" was the question asked and answered in a variety of ways during a fascinating speakers' session that followed this morning's opening plenary. Several expert speakers in a variety of fields provided frank and illuminating commentary on the condition of nuclear now, and on the things that have to change for nuclear energy to be vibrant in the decades to come.
