Recycling Nuclear Waste

American Physical Society Special Session on Nuclear Reprocessing, Nuclear Proliferation, and Terrorism (15 April 2007)
Coauthors: William H. Hannum and George S. Stanford

In the public mind, the foremost reservation about nuclear power is, “What can we do with the waste?” Fortunately there is an answer: We can use the worrisome, very long-lived components as fuel in the right kind of reactors, and then the rest becomes manageable. Will this lead to proliferation of nuclear weapons or to an increase in the threat of nuclear terrorism? Not necessarily. Prudent recycle of nuclear waste will actually reduce these threats while also reducing the time that nuclear waste must be sequestered to a few hundred years instead of thousands.

The Infinite Red-Shift Surfaces of the Kerr Solution

Posted on Posted in Physics

In contrast to the Schwarzschild solution, the infinite red shift surfaces and null surfaces of the Kerr solution to the axially-symmetric Einstein field equations are distinct. Some unusual infinite red shift surfaces for observers following the time-like Killing vector are displayed here for the Kerr and Kerr-Newman solution. Some similarities of the latter to the Reissner-Nordstrom solution are also discussed

Smarter Use of Nuclear Waste

Scientific American (December 2005)
Coauthors: William H. Hannum and George S. Stanford

Reprinted in Oil and the Future of Energy by The Editors of Scientific American Magazine (The Lyons Press, 2007), p. 98.
Fast-neutron reactors could extract much more energy from recycled nuclear fuel, minimize the risks of weapons proliferation and markedly reduce the time nuclear waste must be isolated. (PDF)

Climate Change 2001: A Critique

Posted on Posted in General Interest, Global Warming

This Critique builds on A Global Warming Primer. Like the Primer, its purpose is to help the reader determine whether our understanding of the earth’s climate is adequate to predict the long-term effects of carbon dioxide emissions from the continued burning of fossil fuels, to permit informed public policy decisions. This is a limited critique, looking only at a few topics covered in the latest report of the Intergovernmental Panel on Climate Change (IPCC).
