2.5.4.2 Concentrator This system is identical to that for the Brayton cycle. Potassium Rankine High Temperature Cycle: Total Mass-3.22xlOE6 Kg Non-Lunar Mass=0. Potassium Rankine Low Temperature Cycle: Total Mass=3.70xl0E6 Kg Non-Lunar Mass-0. Steam Rankine High Temperature Cycle: Total Mass-2.38xlOE6 Kg Non-Lunar Mass-0. Steam Rankine Low Temperature Cycle: Total Mass-2.93x10E6 Kg Non-Lunar Mass-0. 2.5.4.3 Heat Absorber It was assumed that 50% of this component would require non-lunar materials. Some possible materials for high temperature parts of this component are Croloy(2.25% Cr- 1% Mo), steel alloys such as (25% Cr - 12% Ni) or (25% Cr - 20% Ni), or nickel alloys such as Rene 41 (10% Co, 10% Mo, .005% B plus Ni, Al, Ti, Fe). Potassium Rankine High Temperature Cycle: Total Mass- 5.31xlOE6 Kg Non-Lunar Mass-2.61xl0E6 Kg Potassium Rankine Low Temperature Cycle: Total Mass-1.08xl0E6 Kg Non-Lunar Mass-0.54xlOE6 Kg Steam Rankine High Temperature Cycle: Total Mass-1.62xlOE6 Kg Non-Lunar Mass-0.8lx!0E6 Kg Steam Rankine Low Temperature Cycle: Total Mass-10.08xl0E6 Kg Non-Lunar Mass-5.04xl0E6 Kg
