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

Canada now produces approximately 85 percent of the world’s supply of Co-60 and more than 50 percent of the Co-60 medical therapy devices and medical device sterilizers.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 […]

Pressurized Heavy Water: Using Available Resources

For a time, it appeared that the goal of an independent nuclear industry might not be possible and construction was begun on a reactor plant that used an imported pressure vessel.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 […]

Letter from the Editor: Reactors With a Can-Do Attitude

Canada decided that it would be prudent to develop a reactor design that could operate on natural uranium. This decision was consciously aimed at making the Canadian nuclear industry independent of American political decision making.One of the highest compliments that you can pay to a submariner is to describe him as someone with a “can-do” […]

Some Reactors CANDU®: What Others Cannot

CANDU® reactors are designed to operate with fuel that is composed of natural uranium dioxide formed into cylindrical pellets and inserted into zirconium alloy tubes. No enrichment is necessary. 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 […]

Keep it Simple: Complex Systems Cost More

It must also be understood that the 60 percent efficient gas turbine combined cycle is a very sophisticated piece of machinery operating with its material at close to maximum limits.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 […]

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

Based on current projections, it appears that the gas turbine is destined to fulfill the majority of the new power plant market in the United States and much of western Europe.Many of the greatest innovations – if carefully investigated – can be seen to be the result of of an inventor recognizing other inventions had […]

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 […]

Economy of Scale?: Is Bigger Better?

It is possible for engineers to make incredibly complex calculations without a single math error that still come up with a wrong answer if they use a model based on incorrect assumptions. Pick up almost any book about nuclear energy and you will find that the prevailing wisdom is that nuclear plants must be very […]

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 […]
