At 9:01 pm on January 3, 1961, the first indication of trouble at SL-1 was received at Atomic Energy Commission Fire Stations. The alarm, which was triggered by one of several measured parameters at the plant, was immediately broadcast over all National Reactor Testing Station radio networks. By 9:10 pm, fire trucks and security personnel […]
In the News June 1996
Power Cutoffs Ordered in Northeast (May 22, 1996) – Unusually hot weather forced several electric utilities in the Northeast United States to cut power to customers who had agreed to power interruptions in return for lower rates and to reduce voltage by 5 to 8 percent in order to protect reserve margins. Affected utilities included […]
PHWR Historical Problem Areas: Sources of Incidents
The pressure tubes of a CANDU® are in a hostile environment that includes a high neutron flux, hot, high temperature water, and a certain amount of hydrogen and oxygen released by the decomposition of water by radiation.Though the CANDU® has proven itself to be a reliable, cost effective and safe power generation system, there are […]
Isotope Production: Dual Use Power Plants
Nuclear reactors are not just a source of heat for power production. They are also an abundant source of neutrons, which allows the plants to be in a process of transmutation which makes the old dream of alchemy a reality. Since neutrons are neutrally charged, they have the ability to insert themselves in a wide […]
Pressurized Heavy Water: Using Available Resources
In many ways a CANDU® nuclear plant is conceptually related to a standard pressurized water reactor plant system. It has two separate heat transfer loops whose fluids never directly interact. The two loops physically meet in large heat exchangers called steam generators, which are very similar in design to those used in PWRs. One fluid, […]
Letter from the Editor: Reactors With a Can-Do Attitude
One of the highest compliments that you can pay to a submariner is to describe him as someone with a “can-do” attitude. This implies that he will cheerfully find a way to overcome any obstacle. Perhaps that is one reason that I have always admired the name, CANDU®, that was chosen for the Canadian heavy […]
Some Reactors CANDU®: What Others Cannot
An understanding of some of the features of the CANDU® reactor design makes it obvious that many of the negative perceptions about nuclear power are, in fact, based on characteristics of a single type of reactor. Simple Fuel Manufacture One common misconception about nuclear energy is that fuel manufacture is a complex endeavor that requires […]
Keep it Simple: Complex Systems Cost More
A first generation Adams Engine might achieve a thermal efficiency of approximately 30-35 percent, instead of the 55-60 percent that is currently being advertised for advanced gas turbine power plants. Many people seem offended by the very idea of producing a system that is less efficient than existing systems, but the important characteristics of a […]
In the news: May 1996
Netherlands Begins NEREUS Study (March 1996) – At the instigation of ROMAWA, a small company led a former Royal Netherlands Navy engineering specialist, the Netherlands government and several large industrial companies have begun a study of a nine megawatt nuclear gas turbine designed for heat and/or power production, district heating and ship propulsion. Capt. Gulian […]
Atomic Gas Turbines: Applying Related Inventions
Many of the greatest innovations – if carefully investigated – can be seen to be the result of of an inventor recognizing other inventions had made it possible to achieve a long awaited dream. For example, the story of the Wright Brothers’ first flight is incomplete without the story of the internal combustion engine. The […]
Letter from the Editor: Small Is Beautiful
At the request of several readers, we have decided to dedicate this issue to discussing the Adams Engine concept. Rather than talking about technical details, however, we have decided to talk about general principles and philosophies. Adams Atomic Engines, Inc. has determined that it is possible to build uranium heated machines that can fulfill many […]
Chernobyl Accident: Advice and Sources
Here is our best advice in case of a reactor accident that releases large amounts of radioactive material. If there is evidence of increased radioactivity in the air, stay indoors and breath filtered air. Forced evacuations make taking this action far more difficult. It is worth the effort to take sensible precautions against inhaling or […]
