Question

RI 6. A 500 MW. PWR is operating. What is the reaction energy per year in MW-day? (10 pts) 7. Boron is used in PWRs as a chemical shim and BWR reactors use boron carbide control rods. Assume that 8-10 of 1 kg natural boron is absorbing neutrons in a reactor. What is the rate of neutron absorption if the 8-10 makes up 19.78 percent of natural boron. Natural boron has an atomic mass of 10.811, B-10 has a microscopic cross section for absorption of 3037 barns, and the reactor flux is 10 n/cm2 s? (15 pts)

Explanation / Answer

A 500 MW plant operating for a year (365 days) could produce as much as 182,500 MW-day

If the is asked answer in MWh than

A 500 MW plant operating for a year (8,760 hours) could produce as much as 4,380,000 MWh
