Optimizing Maintenance Strategies in Power Generation: Embracing Predictive and Preventive Approaches
One of the important design goals for the Fort St. Vrain reactor - really, the second-generation high temperature gas cooled reactor - was to create a core design that would be more compact than that actually used at Peach Bottom. An innovative design was developed using stacked reactor-grade graphite modular blocks which incorporated fuel rods that contained coated fuel particles.
College graduates, as with most industries, are the future of nuclear engineering. How university programs are structured, the professors' involvement in the field, and the opportunities available at the undergraduate and graduate-level are fundamental to the continued growth of nuclear engineering.
This week's Friday Matinee is a three-part presentation delivered originally on January 18, 2018, by the U.S. Department of Energy as a livestream. The session was entitled "Energy Talks: Advanced Research, Nuclear Energy, Water Power."
Did you know that National Engineers Week (NEW) is starting Sunday, February 18? So, it's time to celebrate the engineering profession and help others discover engineering!
The Fort St. Vrain project was innovative in more than one respect, and while it did not blaze the trail in HTGR (High Temperature Gas-cooled Reactor) commercialization - a feat accomplished by the Peach Bottom Atomic Power Station - it did considerably advance the technology toward full commercial operation and duplication on a wide scale through some significant design changes. One of the most interesting of these was the use of a prestressed concrete reactor vessel (PCRV) for the reactor itself and primary components instead of a steel vessel.
An old hand at startups by age 31, Bret Kugelmass is not one to do things by halves. He believes climate change poses a mortal threat to humanity, and that the widespread adoption of nuclear energy is the only way to stem the tide of catastrophe.

What became the Fort St. Vrain Nuclear Generating Station began as a study almost two decades before the plant was completed and led to years of effort to construct a commercial high-temperature gas-cooled nuclear power plant. While the effort did not ultimately lead to a successfully competitive alternative to light water designs, it did add considerably to the knowledge and experience base of gas-cooled reactors specifically and nuclear power generally. We will chronicle the effort in images - mostly using those from an incredible press package in the author's collection. (Photos will enlarge when clicked.)

With the increasing concern these days about the pollutants that commercial ships traveling all over the world's oceans put into the air, there's a rumbling undertone starting again about moving to nuclear powered commercial (that is, non-military) ships. There was a "First Nuclear Ship" era already, and it did give us some valuable lessons.
Students: we know the value of a couple thousand dollars. Receiving an ANS scholarship could mean the opportunity less shifts at work and focus on classes, buying textbooks, or even just eating a bit better (and healthier) than ramen noodles every day. I'm not here to tell you why you can use some extra money. I'm here to tell you all the other reasons why applying for an ANS scholarship is valuable.
This week's ANS Nuclear Cafe Friday Matinee is the very latest video update from Tokyo Electric Power Company on the conditions at 1F -- that is to say, "First Fukushima" or the Fukushima Daiichi nuclear power station.
By now we all know that Energy Secretary Perry's initiative to get the Federal Energy Regulatory Commission (FERC) to consider longevity of fuel supply has fallen and been replaced with an order to study the situation and, hopefully, come up with some kind of solution within 60 days. FERC's press release from yesterday reads in part thus:
Breaking: In a unanimous vote, the Georgia Public Service Commission (PSC) has APPROVED a multi part motion by Commissioner Tim Echols which allows the Vogtle 3 and 4 project to move forward, but which reduces burden on ratepayers and places more on shareholders of the owners. Georgia Power accepted the new conditions immediately after the PSC vote and will continue construction of the project under the new management structure, which itself was approved by the Commission as one part of Echols' proposal (although it neither approved nor disapproved of the actual owners' agreement terms; it simply approved the project management structure).
There have been a number of significant and/or interesting developments in the nuclear energy field recently, with large light-water reactor business taking the fore. Here are some highlights:

•Shippingport started up 60 years ago today. On December 2, 1957, the reactor at the Shippingport Atomic Power Station, which was America's first, full-scale nuclear power plant, was made critical for the very first time. This event occurred fifteen years to the day after the historic first startup of the first nuclear reactor ever - the CP-1 pile near Chicago. Many important people, including Admiral Rickover, were present at the startup.
"Some recent work by E. Fermi and L. Szilard, which has been communicated to me in manuscript, leads me to expect that the element Uranium may be turned into a new and important source of energy in the immediate future." - Albert Einstein, letter to President Franklin D. Roosevelt, August 2, 1939
A short while back in early November, I decided to conduct a poll on Twitter - that oft-maligned, mostly misunderstood, microblogging site on which instantaneous outreach is seriously tempered by a roughly 19-minute-post-visibility lifetime. Even with the limitations, I thought my first-ever use of the polling tool would produce a pretty predictable result. I was off the mark.
