Dr. John Gofman has died

Dr. John Gofman has passed away at the age of 88 of heart failure.Dr. Gofman is of special interest to those of us fascinated by energy from thorium since he (under the guidance of Dr. Glenn Seaborg) discovered uranium-233 and its fissionability. I remember reading somewhere (but I've not been able to find the quote) that after realizing that thorium could be turned into U-233, and that U-233 produced enough neutrons in thermal fission to sustain the conversion and consumption of further thorium, that Seaborg told Gofman that he had just solved the world's energy needs for a thousand years.Dr. Gofman was extremely anti-nuclear and devoted most of his ...

The Modified Geometry 2 Fluid Molten Salt Breeder

Dr. David LeBlancPhysics DepartmentCarleton UniversityOttawa, CanadaIn this presentaion I will attempt to explain a completely new concept for a Liquid Fluoride or Molten Salt Breeder Reactor. The basic idea may seem almost trivial in nature, given its simplicity, but I hope its importance will be evident once all aspects of the design are examined. I am not aware if this idea is completely original as I think it likely to have been at least discussed during early days at Oak Ridge. Regardless, I believe it represents a major step forward in reactor design. I will first to give enough background such that its advantages and disadvantages can be ...

The End of Crandall Canyon

The terrible story of six trapped miners in the Crandall Canyon mine in Utah appears to have come to a painful and drawn-out conclusion. The mine owner, Robert Murray, told the families of the trapped miners that their loved-ones are most likely dead, and that further rescue attempts will not be made since there is no sign of life in the mine.In addition to the six men who are most likely dead in the mine, there were three others who were killed during rescue attempts.Tragedy is a fact of life, and I certainly do not want to diminish that. But there are some activities that carry a far greater risk of death and injury than others, and mining coal is ...
