SingaporeFlyer 201x268The American Nuclear Society's ANS Nuclear Cafe is proud to host the 149th edition of the Carnival of Nuclear Energy.  Each week, the top English-language nuclear bloggers and authors contribute their best posts to the Carnival, which appears at one of a rotating number of sites.  Reading the Carnival each week is the best way to keep on top of the issues that experts in the nuclear blogosphere believe are most important, and keep up on all types of events and news.  With that, let's get right to it!

Update and Perspective on Small Modular Reactor Development

March 21, 2013, 6:00AMANS Nuclear CafeJim Hopf

The US Department of Energy has a $452 million program to share development and licensing costs for selected small modular reactor (SMR) designs. The DOE's goal is to have an operating SMR by ~2022. Last November, the DOE awarded the first grant to the B&W mPowerTM reactor. In more recent news, the DOE has decided to issue a follow-on solicitation to enter a similar cost-sharing agreement with one or more other SMR vendors (and their SMR designs). The status of development and licensing for several SMR designs are summarized below.

Rising Stars in Nuclear Science and Engineering Symposium

Recently I had the honor of joining the "Rising Stars in Nuclear Science and Engineering Symposium" at the Massachusetts Institute of Technology. It was a unique symposium, inviting a dozen Ph.D. candidates and early postdoctoral fellows to showcase their research, and to engage in rich discussions of early career strategies and challenges with exceptional researchers in the field.

ANS Nuclear Technology journal seeks Editor

March 19, 2013, 6:00AMANS Nuclear Cafe

The American Nuclear Society is soliciting names of qualified members who are interested in becoming the editor of the ANS journal Nuclear Technology (NT). Dr. Nicholas Tsoulfanidis, Professor Emeritus of Nuclear Engineering, Missouri University of Science and Technology, has served as editor of NT since June 1997. During his term, Professor Tsoulfanidis has done an outstanding job. He has raised NT's reputation for technical excellence and has kept up a full schedule of publishing monthly issues.

San Onofre debate now more public – and more technical

March 15, 2013, 6:00AMANS Nuclear CafeWill Davis

The debate over the continuing investigations into steam generator U-tube problems at San Onofre Nuclear Generating Station (SONGS) last week entered a new phase of heightened publicity and public scrutiny as the Nuclear Regulatory Commission (NRC) released Mitsubishi documents which detailed that company's investigations into the root causes of the problems.

Fukushima Two Years Later

March 7, 2013, 2:58PMANS Nuclear CafeWill Davis

At about a quarter to three in the afternoon on March 11, 2011, a gigantic and unprecedented earthquake struck just over 110 miles off the coast of Fukushima Prefecture in Japan. The quake was followed, just over 40 minutes later, by the first of several rounds of tsunami, which inundated enormous areas and eradicated entire towns and villages. Over 19,000 people were killed or are still missing, and over 6,000 survivors were injured.

On federal investment in Small Modular Reactor technology

March 1, 2013, 10:45PMANS Nuclear Cafe

Taxpayers for Common Sense on February 27 issued a press release targeting the Department of Energy for "wasting more than half a billion dollars" on its small modular reactor (SMR) development cost-sharing program. Leaving aside the historically essential role of government investment in developing, advancing, and bringing to market innovative energy technologies-and the fact that early government investments in nuclear energy technology now pay back enormous dividends to all Americans in billions of dollars' worth of affordable and emission-free electricity generation every year-many of the advantages of advanced SMR energy technologies were overlooked or misconstrued in the group's press release and policy brief.

Preparing to restart: Tsunami safety measures at Japanese nuclear power stations

February 28, 2013, 1:51PMANS Nuclear CafeWill Davis

The approach of the second anniversary of the Great East Japan Earthquake of March 2011 finds nuclear energy in Japan at a crossroads. After the quake and resulting tsunami, the nuclear plants in Japan that did not shut down immediately eventually all had to shut down for their required, scheduled outages. Political pressures, for the most part, prevented any near-term chance of any of them restarting, it seemed at the time. When Tomari Unit 3 shut down in May 2012, Japan found itself with not one single operating nuclear power plant for the first time in decades. Since that time, only two nuclear units have restarted-Ohi Units 3 and 4 in July 2012. Other plants, rumored to be "next" to start up, have still not started up, although they may soon. The question that springs to mind is naturally, "When will the majority of the plants be allowed to restart?" The more insightful question, though, is, "What will have to be done in order to allow any plant to restart?" And how can we tell which will start first-is there any clue present now? Yes, there is.
