On the morning of September 12, 2021, reactor number 1 of the eagerly awaited HTR-PM project was taken critical for the first time. Initial criticality for any new reactor is a big deal for the people involved in the project; this one is a big deal for the future of nuclear energy. It might also…
X-Energy is the lead recipient for one of two industry groups selected to receive $80 M in Department of Energy (DOE) funding as part of a public-private partnership program to demonstrate advanced nuclear power plants on an aggressive time table. Its primary partner in the endeavor is Energy Northwest, which currently owns and operates the…
Under our current energy paradigm, nuclear power has the reputation of needing enormous up-front capital investments. Once those investments have been made and the plants are complete, the payoff is that they have low recurring fuel costs. Just the opposite is said of simple cycle natural gas fired combustion turbines. They require a small capital…
Addressing Recommendations of MIT Future of Nuclear Energy In a Carbon Constrained World The Massachusetts Institute of Technology (MIT) is a world renowned institution that has produced thousands of highly educated engineers and scientists. It is generously supported by foundations, corporations and governments. In 2003, the MIT Energy Initiative, began publishing a series of reports…
It would be a huge benefit to the earth’s atmosphere if China, India, Brazil and the US could reduce direct coal burning while still making use of much of the capital that they have invested in building coal fired power plants. It would make an even larger difference in reducing air pollution in the areas…
U-Battery was one of the more intriguing presenters at the Advanced Reactor Technical Summit (ARTSIII) held at the Oak Ridge National Laboratory last week. Even though this was a technical summit, the segments of the presentation that captured my attention were the business model and the funding source. However, certain technical choices are vital to…
On Tuesday, October 27, three leaders from X-Energy spoke to the Virginia ANS chapter about their company and the Xe-100, the high temperature, pebble bed gas reactor power system that they are designing. During the presentation, meeting attendees learned that X-Energy is an early phase start-up with a total staff of a few dozen people,…
StarCore Nuclear is a Canadian company whose co-founders, David Dabney and David Poole, are experienced engineers and businessmen. They have spent most of the past six years developing a technology and a business model aimed at providing reliable, emission-free electrical power and heat to remote locations. The basis of their technology is a high-temperature helium…
The first HTR-PM (High Temperature Reactor – Pebble Module), one of the more intriguing nuclear plant designs, is currently under construction on the coast of the Shidao Bay near Weihai, China. This system uses evolutionary engineering design principles that give it a high probability of success, assuming that the developers and financial supporters maintain their…
What if it was possible to combine the low capital cost, reliability, and responsive operations of simple cycle combustion gas turbines with the low fuel cost and zero-emission capability of an actinide (uranium, thorium, or plutonium) fuel source? Machines like that could disrupt a few business models while giving the world’s economy a powerful new…
Seventy one years ago — on December 2, 1942, at 3:25 pm — Enrico Fermi and his team achieved the first controlled, man-made, self sustaining chain reaction in a simple reactor. In recognition of that historical event, several of my nuclear colleagues refer to December 2 as “Critmass” (short for critical mass). The first nuclear…
The Idaho National Laboratory released the following exciting news on September 25, 2013. IDAHO FALLS — A safer and more efficient nuclear fuel is on the horizon. A team of researchers at the U.S. Department of Energy’s Idaho National Laboratory (INL) and Oak Ridge National Laboratory (ORNL) have reached a new milestone with tristructural-isotropic (TRISO)…
