Rhenium
Z = 75 · Transition Metal · 186.2 u
Nuclear Engineering Significance
Relatively high thermal absorption (σ_a = 89.7 b). Used in high-temperature superalloys but generally avoided in reactor neutron environments due to absorption penalty. Rhenium alloying in turbine materials is relevant to nuclear power plant balance-of-plant components.
