2002-6-17 · Therefore, any discussion of the sensitivity of a nuclear power plant to terrorism must be tempered with the realization that all of modern society is vulnerable - and the effects can be particularly bad when the is a large concentration of easily useable fuel whether water, or hydrocarbon, or uranium in an operating reactor.

Energy Glossary

FISSION -- A release of energy caused by the splitting of an atom's nucleus. This is the energy process used in conventional nuclear power plants to make the heat needed to run steam electric turbines. FISSIONABLE MATERIAL -- A substance whose atoms can be split by slow neutrons. Uranium-235, plutonium-239 and uranium-233 are fissionable materials.
