According to Table 5.8, U-235 and Pu-239 are twain non-1/v absorbers. If their ssion peevish sections at 0.025 eV are 585 barns and 747.401 barns what values should we use for their ssion peevish sections for the entire thermal essence class (from E ~ 0 to E ~ 1.0 eV)? Assume the sphere of the fuel rods is 1000°C. Can their ssion peevish sections be interpreted as the thermal class ssion peevish sections in this contingency?
