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.
One of the main problems of the use of nuclear energy is nuclear waste management. An EU-funded project focuses on assessing the use of minor actinides from the used nuclear fuel as a fuel for next-generation nuclear reactors.
