2. Silver-indium-cadmium alloys, generally 80 % Ag, 15 % In and 5 % Cd, are a common control rod material for pressurized water reactors.
3. Due to the combination of refractory properties, high thermal conductivity, and the advantages of large stoichiometric boron content outlined in the above discussion of integral neutron absorbing fuel pellet cladding, refractory diborides have been used as control rod materials and have been studied for use in space nuclear power applications.
4. Hafnium diboride also suffers from high susceptibility to material degradation with boron transmutation, but its high melting point of 3380 癈 and the large thermal neutron capture cross section of hafnium of 113 barns and low reactivity with refractory metals such as tungsten makes it an attractive control rod material when clad with a refractory metal.
5. The latter is used as a control rod material in both PWRs and BWRs . 10 B / 11 B separation is done commercially with gas centrifuges over BF 3, but can also be done over BH 3 from borane production or directly with an energy optimized melting centrifuge, using the heat of freshly separated boron for preheating.
