Calvert Cliffs Plant; two unit nuclear generating station. Baltimore Gas and Electric Company brochure, October 1980.

I received an email this morning (in the midst of my daily avalanche of promotional emails) with a link to a brief story about uprating of nuclear plants worldwide (in other words, increasing the power output of an already-built plant)-what had been done, how many were planned, and so forth. I wondered to myself just how many nuclear plants in the United States had been uprated, and when they started-and given the recent hullabaloo over the recent U.S. Environmental Protection Agency CO2 emission policy, it seems like (in addition to discussing small modular reactors) we might also want to toss the uprate card back on the table. Instead of flat or only slightly rising demand for electricity, we may face a steady lowering of generating capacity as plants that are high CO2 emitters (and thus violators) get shut down. Sure, renewables will play a part, and so will increased efficiency, but having more power is better than having less, or too little. I found no quick and easy reference for the kind of analysis I wanted, so I took a little time and did it myself.

In February, the U.S. Department of Energy finally announced the approval of a federal loan guarantee for the Vogtle-3 and -4 reactor project under construction near Waynesboro, Ga. The approval came after four years of negotiations between the government and the utilities involved in the Vogtle project.

A group of past presidents and fellows of the American Nuclear Society has composed an important open letter to ANS on a topic that has been the subject of controversy since before I first joined the society in 1994. The subject line of that letter is "Resolving the issue of the science of biological effects of low level radiation." The letter is currently the only item on a new web site that has been created in memory of Ted Rockwell, one of the pioneers of ANS and the namesake of its award for lifetime achievement.

Such was the provocative title of the Focus on Communications Workshop held at the 2014 American Nuclear Society Annual Meeting on the afternoon of Wednesday, June 19.

Thank you for your remarkable contributions to continuing progress and advancement in nuclear sciences and technologies-and congratulations to American Nuclear Society honors and awards recipients at the 2014 ANS Annual Meeting.

It's time for the 213th Carnival of Nuclear Energy Bloggers and Authors, hosted this week right here at the ANS Nuclear Cafe.  It's a big week for ANS, with the Annual Meeting going on in Reno... so without any further remarks we'll dive right in!

One of the many highlights at American Nuclear Society national meetings is the opportunity to hear terrific communicators sharing their insights and best practices, along with lively and informative panel discussions that follow. The June 2014 ANS Annual Meeting offers three of these popular sessions-if you will be in Reno, Nev., be sure to schedule them on your meeting calendar.

The recent U.S. Environmental Protection Agency announcement of policy regarding carbon emissions from power plants has triggered a renewed interest in nuclear energy over the past few weeks; along with this of course comes a focus on small modular reactors (SMRs) and their availability for replacing existing fossil-fueled plants or facilities. We have discussed this topic here at ANS Nuclear Cafe before, in terms of the possibility of adding an SMR onto an existing facility-see "The Hook-Ons."

It's time to stop worrying about the risk of a spent fuel pool fire at decommissioned nuclear reactors. Even at operating reactors, there is good reason to put the risk quite low on any table that prioritizes items worth fretting over.

There is a lot going on in nuclear energy lately-and a correspondingly sizable haul of contributions by the internet's nuclear bloggers this week, posted at Next Big Future.  A new US EPA rule on power plant carbon emissions figures prominently.

CNBC's Mary Thompson visits the construction site of two new nuclear energy reactors at V.C. Summer Nuclear Generating Station in South Carolina, and talks with South Carolina Electric & Gas Company Chief Nuclear Officer Jeffrey Archie about new construction and operation jobs-in South Carolina and industry-wide.

Our Sierra Club local chapter recently sponsored a joint presentation-by two local anti-nuclear groups. A small audience of attendees heard of the horrors that citizens might expect during Vermont Yankee's upcoming decommissioning. The presenters claimed that their participation in decommissioning will be needed to insure that all goes well because Entergy, and the US Nuclear Regulatory Commission, can't be trusted. Included as usual was a litany of things about to go wrong-all caused by nuclear power!

The subject of plutonium disposition has a long history that dates back to the end of the Cold War, combining complex technical, policy, and diplomatic issues. A discussion of this history is timely because the Department of Energy recently released a report¹ evaluating technological alternatives to the current approach of disposing of plutonium using mixed oxide (MOX) fuel. One option-referred to as "downblending and disposal"-was assessed favorably in terms of cost, timeliness, and technical risk, but it introduces new technical and political challenges. This blog post provides a brief summary of the storied history of plutonium disposition.

With Memorial Day Weekend at hand, this is a good time to sit down and take a more in-depth look at the history, and the future, of nuclear energy.  Dr. Roger Blomquist of Argonne National Laboratory leads a public tour on this fascinating topic.  Note the video begins at 0:40 and Dr. Blomquist begins at 7:30.

NS Savannah, Baltimore, May 17, 2014

The weekend of May 17-18, 2014, saw a beehive of activity on board the beautiful nuclear powered ship N.S. Savannah, docked now in Baltimore. The ship was being prepared on May 18  for open public touring-a rare event indeed for this ship that is still a Nuclear Regulatory Commission licensed facility-in commemoration of National Maritime Day (which actually is May 22.) To this end, the ship was abuzz with workers from the U.S. Maritime Administration (MARAD) and its ever-present Ship's Master, Erhard Koehler, as well as workers from other organizations and, of course, the N.S. Savannah Association (NSSA), which works with MARAD to preserve and restore the ship.

With the recent shutdown of four reactors and another scheduled closure later this year, there is increasing concern over nuclear plant shutdowns in the United States, and the idea of policy intervention to prevent further closures is gaining political traction.
