Canadian Nuclear Laboratories (CNL) has fabricated proprietary advanced fuel pellets for Ultra Safe Nuclear Corporation's (USNC) Micro Modular Reactor (MMR). This is the first time that a TRISO-based nuclear fuel has been manufactured in Canada. Read more
Modern TRISO fuel designs are under consideration for an assortment of advanced reactors, including high-temperature reactors and microreactors, and even as accident-tolerant fuel for light water reactors. Read More
The U.S. Senate today confirmed Jennifer Granholm as U.S. Secretary of Energy. Secretary Granholm is the former Attorney General and Governor of Michigan. Read More
There’s a lot of buzz around TRISO particles, and with good reason. The particles consist of a fuel kernel surrounded by three isolating layers designed to withstand intense pressures and temperatures of up to 1600 °C, making them capable of containing the fuel even in the worst-case scenarios.

The initial startup of the Fort St. Vrain station finally happened on January 31, 1974, which was roughly one month after the station had received an operating license from the Atomic Energy Commission (AEC). Read more
In the last half of 1968, Public Service of Colorado obtained the necessary approvals from the US Atomic Energy Commission and from the Colorado Public Service Commission to begin the actual construction of its Fort St. Vrain Nuclear Generating Station. Read more
We continue this look at original materials covering America's second commercial High Temperature Gas-cooled Reactor (HTGR) with the examination of components of the NSSS, or Nuclear Steam Supply System. Read more
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. Read more
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. Read more
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. Read more
Dr. Yujie Dong is a Professor in Nuclear Engineering at Tsinghua University, Beijing, China he will be presenting a Webinar Series 17: Design, Safety Features and Progress of the HTR-PM. Read more
The pressure vessel head has been installed at one of the two high-temperature gas-cooled reactor units that make up the demonstration HTR-PM plant under construction at Shidaowan in China's Shandong province. Read more
An advanced technology that uses nuclear energy to produce high temperature heat for industry could be an important tool in cutting carbon dioxide emissions worldwide, said experts at an IAEA roundtable discussion today. The technology, which is expected to be deployable in coming years, could add to low carbon energy sources for use for transportation and a number of industrial applications requiring high temperature heat.
