Webthe production of hydrogen is at the upper end. Up to about 550° Celsius, the heat can be supplied by steam; above that, requirements must be served directly by process heat, since steam pressures become much higher than 550°. The upper limit of 1000° for nuclear-supplied process heat is set on the basis of the long-term WebHeat Source As discussed earlier in Section 2.3.1, heat is produced within a nuclear reactor as a result of fission. The energy released is initially manifest primarily as the kinetic energy of fission products, of fission neutrons, and of gamma radiation.
