Westinghouse’s eVinci is a 15 MWth, 5 MWe micro reactor. Westinghouse often refers to it as a nuclear battery. Unlike conventional nuclear power plants, eVinci uses no water and doesn’t produce steam. The eVinci is not “just another way to boil water.” There are no pumps in the system that moves heat out of the…
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…
Gordon McDowell, the film maker who produced Thorium Remix, has released some additional mixes of material gathered for that production effort. One in particular is aimed at those people whose main concern about using nuclear energy is the often repeated question “What do you do with the waste.” Many people who ask that question think…
Yesterday morning I wrote a post titled Where is Hyperion Power Generation headed now? By the time I was ready for a lunch break, I had received an email from the Chief Operating Officer of Hyperion Power Generation offering to fill me in on some of the details that he was able to make public….
It is almost as if NASA, ever cognizant of the need for taxpayer support of its programs, put this useful device “in the closet”, using it when necessary but maintaining an unofficial policy that technical details were best kept from public view. This issue was inspired by a request from one of our Internet readers…
The Apollo missions to the moon are famous for heroic astronauts, exciting first steps and incredible pictures that fired the imaginations of a whole generation of scientists, engineers and school children. Mixed in along with the hoopla about sending men into space on huge, fire spewing rockets, however, was some serious science. Each time the…
Tiny, milliwatt capacity RTGs found a home inside the chests of middle aged people in countries like France, Russia and even the United States. These devices – about the same size as a AA battery – were designed to power cardiac pacemakers. Not all of the RTGs that have been produced have been designed for…
Strontium is not associated with nuclear weapons and has never been called the most deadly element known to man. There is a precedence in the United States for widely licensing small quantities of sealed Sr-90; it is used in some aircraft ice detection systems. Essentially all RTGs that have been produced have been designed for…
The only planned use of RTGs in the US space program in the near term is the unmanned, 1997 Cassini mission to explore Saturn. The Cassini spacecraft will be powered by three General Purpose Heat Source Radioisotope Thermal Generators (GPHS RTGs) each designed to provide 276 W of electrical power at the beginning of the…
Atomic energy provides an amazing source of concentrated power. The potential applications that have been proposed are widely varied. There is room for unlimited innovation and creativity. Imagine what it would be like to have a battery that could provide power for several decades without recharging. Sounds almost like science fiction. Fact, in this case,…
