1. An anti-proliferation fissionable uranium fuel salt consisting of:
one or both of UCl3 and UCl4;
one or more chloride salts selected from NaCl, MgCl2, CaCl2), or KCl; and
one or more chloride salts of activation dopants wherein the activation dopants are selected from stable isotopes of Co, Cs, Ce, La, Pr, Nd, Bi, Ir, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, or Ra;
wherein the anti-proliferation fissionable uranium fuel salt has an FOM greater than 1.0 prior to fissioning the anti-proliferation fissionable uranium fuel salt and, after no more than 300 days of fissioning, the anti-proliferation fissionable uranium fuel salt has an FOM of less than 1.0 due to the conversion of the activation dopants into protecting isotopes.
