Nuclear weapons vs. nuclear reactors

Nuclear reactors use the energy from fissioning atoms to heat water (or gas or some other heat-transfer medium). This hot fluid then transfers the heat to ultimately produce electricity. In a water-cooled reactor, for example, the hot water will be used to produce steam, and the steam then spins turbines in order to produce electricity.
