Thus, the ALMR system forms a complete fuel cycle which can last for centuries. Weapons Burning The ALMR core would most efficiently use unwanted weapons-grade Plutonium. Upon fuel processing of the Plutonium, the Plutonium could no longer be used for weapons. In fast neutron fluxes, actinides can be fissioned to produce power. Since the ALMR generates power using a fast neutron flux, it is ideal for eliminating the long-lived component of radioactive waste.
Debates exist, however, as to whether it can be actually done.
Though this was also recognized as a benefit, some people would consider the breeding of Plutonium to be dangerous because of fear that the Plutonium could be used by someone to make a nuclear weapon. Thus, the ALMR will have an image problem if it breeds. Thus, reactor Plutonium is no more dangerous than Uranium. Sodium-Water Interactions Sodium reacts violently with water and air. This creates an obvious problem and care must be taken with respect to the piping.
