Nuclear Reactor Types - Stanford University
large.stanford.eduBy moving to greater levels of enrichment of U235, it is possible to tolerate a greater level of neutron absorption in the core (that is, absorption by non-fissile, non-fertile materials) and thus use ordinary water as both a moderator and a coolant. The two commercial reactor types based on this principle are both
Review of the Environmental Impact of Nuclear Energy
www.iaea.orgnatural result of growing socio-economic activities and the rising standard of living. The increasing global demand for energy has hitherto been met to an increasing extent by the use of fossil fuels and hydro power. Nuclear energy has been developed and used commercially for about two decades to meet a fraction of the electrical energy needs.
