Choosing Between Dependable and Intermittent Clean Sources of Energy

September 12, 2016, 3:48PMANS Nuclear CafeAlex Pavlak, Ph.D., P.E.

On June 2 Exelon announced the early retirement of two nuclear power plants (Quad Cities and Clinton) in Illinois. On June 21 Pacific Gas and Electric announced a decision to close the Diablo Canyon nuclear plant in California. Those decisions have been explained in part on cost. The plants are aging, maintenance cost has been increasing, and low natural gas prices have reduced the cost of competing electricity. When a nuclear plant's contract comes up for renewal, politicians who think natural gas prices may stay low forever refuse to renew the nuclear plant's contract at a higher price.

Diablo Canyon Shutdown Gets Personal

While the nuclear community has been encouraged by the recent action taken by New York giving recognition for the intrinsic value of carbon-free emissions from nuclear power, the same cannot be said for California. New York has found value in keeping their nuclear power plants operational, but unfortunately, given the political situation in California, it is unlikely that any proposed resolutions in favor of keeping Diablo Canyon Power Plants (DCPP) open will happen.

Bootcamp Catalyzes Industry-wide Innovation Conversation

September 2, 2016, 3:06PMANS Nuclear CafeKathy Shield and Caroline Hughes

Nuclear Innovation BootcampTo increase the presence of nuclear energy as a clean energy source in the United States and around the world, we need new ideas, we need old ideas in the form of new companies, and we need technologies to make the leap from the lab bench or computer simulations to the real world. The DOE GAIN initiative will make national lab resources more available for small nuclear companies and startups, but for GAIN to make real inroads in the industry, the industry needs more startups.

Flashpoint in Kagoshima

On August 26, a special meeting was arranged in Kagoshima Prefecture, Japan, which is the location of Kyushu Electric Power Company's Sendai Nuclear Plant.  At that meeting, the newly elected prefectural governor, Satoshi Mitazono, presented Kyushu Electric Power Company President Michikai Uriu an official request to shut down the operating reactors at Sendai and repeat the safety checks performed on the nuclear plants.

Friday Nuclear Matinee / Double Feature Matinee!

August 26, 2016, 2:36PMANS Nuclear Cafe

This week on the Friday Nuclear Matinee we have a short double feature!  Up first is a time lapse video from Georgia Power showing last weekend's movement of the million-pound CA20 module from the MAB or Modular Assembly Building and the module's emplacement at Vogtle Unit 4.  This is the heaviest lift conducted in 2016; the Unit 3 CA20 module was placed prior to this year.

In an Era of "Firsts," an "Almost"

The era of the "first nuclear build" in the United States (from the Manhattan Project of the Second World War at the earliest, through the final commercial plant orders in 1978) was by nature one of nearly continuous "firsts" in its opening decades, as nuclear energy moved from being a thought to a possibility to a reality and took on many forms and nuances.

Nuclear Innovation Bootcamp: Developing The Next Generation of Business Leaders

ANS President Andy Klein speaks to students at the Bootcamp

I had a chance to meet with the students at the Nuclear Innovation Bootcamp at the University of California, Berkeley, on August 10. We talked about the importance of nuclear energy, the value of membership in the American Nuclear Society (ANS) (I noted that most of the approximately 40 people in attendance already are ANS members), and the challenges to nuclear plant construction and operation. We also noted the successes in New York to include nuclear in their Clean Energy Standard and the announcement of the resulting important planned sale of the FitzPatrick plant to Exelon.

Exelon Agrees to Buy FitzPatrick

In what may well prove to be a historic deal, Exelon announced this morning (August 9) that it had agreed in theory to purchase the James A. FitzPatrick nuclear station in upstate New York from its present owner, Entergy.  This ends a long period of anguished waiting and watching, which began in February when Entergy announced it intended to close the plant and which was brought to a high level of tension in July when it was revealed that Exelon was examining purchasing the plant.

The Hubbub Over Iran's Heavy Water

August 7, 2016, 10:17PMANS Nuclear CafeAndrew Reimers

More than a year after the P5+1 and Iran agreed to the terms of the Iran nuclear deal, the debate in the U.S. over the deal's implementation is far from over. In recent months, part of that debate has been focused on what should be done about Iran's stockpile of heavy water. The ongoing controversy offers an opportunity to discuss the provisions in the deal regarding the country's heavy water program and to provide some context for the role of heavy water in the history of nuclear proliferation.

Elk River - Rural America's First Atomic Power Plant

The Elk River reactor, as it was generally known in the AEC parlance of the day, was a pioneering effort in America's nuclear energy history.  Hailed widely as "Rural America's first atomic power plant," the intention was to provide a pilot installation of a small, simple, and inexpensive nuclear steam supply system that could be duplicated at many far flung locations.  Unfortunately for the concept, the Elk River plant in the end proved unable to meet the task for technical reasons; yet, it remains firmly in history as one of the well known early nuclear energy installations.  What follows is a brief history of the project and its major players.
