A boiling water reactor operates at 1000 psi. At that pressure the density of water and of steam are, respectively, 0.74 g/cm and 0.036 g/cm. The microscopic cross sections of H and 0 thermal cross sections are 21.8b and 3.8 b. a. What is the macroscopic total cross section of the water? b. What is the macroscopic total cross section of the steam? c. If, on average, 40% of the volume is occupied by steam, then what is the macroscopic total cross section of the steam- water mixture? d. What is the macroscopic total cross section of water under atmospheric conditions at room temperature?
