Last night I participated in a well-attended meeting of the Virginia chapter of the American Nuclear Society. It was great to be surrounded by a bunch of nukes who were interested in learning about technical developments and in discussing the current local and national political situation from an energy perspective. Before dinner, I had the […]
Graphite Moderated Reactors
Pebble bed reactor safety demonstration test – ABC video from 2007
I spent about 15 years trying (unsuccessfully) to get a small modular reactor company off the ground. Our concept was based on an adaptation of the successful German pebble bed demonstration reactor called the AVR. In 2003, Tsinghua University in China completed the construction of the HTR-10, which was essentially a direct copy of the […]
The Accident at Chernobyl: What Caused the Explosion?
On April 26th, 1986, at 1:23 am, Alexander Akimov did what he and thousands of other nuclear plant operators have been trained to do. When confronted with confusing reactor indications, he initiated an emergency shutdown of Unit 4 of the large electricity generating station near Pripyat in Ukraine. By doing so, he unwittingly initiated an […]
CO2: First Choice for Power Reactors
During the period from 1946 until 1954, the single most important constraint governing the development of peaceful uses of atomic power was the Atomic Energy Act of 1946. This American law – passed after a failed attempt to establish an international control regime for nuclear materials – made it illegal to trade in nuclear knowledge […]
Common Myths: Is Nuclear Waste a Huge Problem?
One of the main reasons for publishing this letter is to add a healthy dose of reality to the mythology that has surrounded the atomic energy field. There are so many of these myths that this column will be a regular feature of the Atomic Energy Insights. One of the most prevalent myths is that […]
In the beginning: A 1942 Experiment Shows the World It Can Be Done
On December 2, 1942, Enrico Fermi and a small band of scientists and engineers demonstrated that a simple construction of graphite bricks and uranium lumps could produce controlled heat. Let’s look back to see how simple that first reactor was. Behind the Scenes The space chosen for the reactor was a squash court under the […]
