Safety is the state of being "safe" (from French sauf), the condition of being protected from harm or other non-desirable outcomes. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk.
Safety is a major challenge for the new generation IV (Gen-IV) fast neutron reactors. Ongoing research and development (R&D), supported by the EU, will update or develop existing computer codes to accurately model innovative reactor designs and accident scenarios.
