Compute the mass (in kg) of U-235 in the reactor UN fuel.

The boiling water reactor (BWR) nuclear steam supply system (NSSS) includes just one pressurizer.

Calculate the average thermal microscopic fission cross-section (in barns) of the U‑235 at a temperature of 800°C.

If the multiplication factor is greater than unity, a reactor is said to be .

The remaining problems should be solved on your ruled white paper and the entire solution submitted.  Show and submit all your work; otherwise, a score of zero must be awarded.  All data utilized in the solutions to these problems (besides that given in the problem statement) must be from the Lamarsh Introduction to Nuclear Engineering textbook.  Besides submitting the entire solution, please also enter the final answers into the Canvas answer boxes below to demonstrate that the solution was arrived at prior to the scanning and uploading period.  Enter each of your final answers into Canvas to four (4) significant digits using the units specified in the problem statement.  If you are not done with a problem, enter the last number on your handwritten solution into the Canvas answer box. Within the next decade, NASA is planning to deploy a fission surface power (FSP) source on the moon. The FSP is to have an output of 40 kWe from a 245 kWt reactor. The FSP reactor is composed of 165 kg of 19.75% (wt%) enriched uranium nitride (UN) with a density of 13.5 g/cm3, and 50.0 kg of yttrium dihydride (YH2) moderator. Use these specifications to solve the remaining problems to 4 significant figures each.
