Gr 7-12 Helgerson presents a clearly-outlined account of how nuclear power plants work, what can go wrong, and the best-known of the world's nuclear accidents. His style and vocabulary are well-chosen for the intended audience, and the illustrationsphotos and diagramsare well-keyed to the text. But in attempting to be objective, he seriously misrepresents the anti-nuclear position as simply interested in other ways of producing the same amount of energy, all of which have their faults. The one source of energy he doesn't mention is the most important to anti-nuclear experts: increased energy efficiency, primarily through conservation. In addition, he describes Soviet unwillingness to report the Chernobyl incident but ignores a similar attempted cover-up by the management of the American Three Mile Island plant. Another omission is the danger of heat pollution of the environment from nuclear plants' cooling apparatus. Nigel Hawke's Nuclear Safety (Gloucester Pr, 1987) presents much the same information in a more pictorial form, with a definite British emphasis, but the same technological viewpoint. Ann E. Weiss' The Nuclear Question (HBJ, 1981) addresses the same issues from a much more objective position, although without the currency of information about Chernobyl.
