From Wikipedia, the free encyclopedia

Let me suggest something to make the text clearer. 1) The definition is misleading. It is better first to write something like "A moderated nuclear explosion results from a nuclear chain reaction mediated by moderated neutrons. With moderated neutrons fissile cross-sections are much higher than with fast neutrons, hence less fissile material is required in a moderated device to reach criticality", because this rather than its relation to criticality accidents is the defining property of the effect. 2) A citation is certainly needed for Chernobyl. 3) The Manhattan project produced the idea of a chain reaction of fast neutrons in metallic uranium or plutonium, but not exactly pure. These are often alloys with some other metals to improve physical characteristics of plutonium. 4) "The explosive power of a moderated explosion is limited, typically it may be equal to a chemical explosive of similar mass" -- this is probably misleading. As far as I have understand George, 1 kg of water-solved uranium produce little energy, but still hundred times more than 1 kg TNT. Colchicum 14:38, 20 September 2007 (UTC)

Yes, and "suggested nuclear weapon design" rather than "nuclear weapon design". Colchicum 14:42, 20 September 2007 (UTC)
