Assuming that neutrons are in thermal equilibrium with their surroundings, determine the most probable velocities at the temperature of 557°F.

 

Question 2

Determine k_eff when the reactivity is equal to -38.9 x 10^-4 Δk/k.

 

 

Question 3

A new type of reactor is being tested. The number of neutrons in the core is 1500 at t = 0 seconds. Determine the number of neutrons after 135 generations assuming that k_eff = 1.0008.

 

Question 4

A test is being performed in a reactor. The reactor has a neutron source that produces 9.89 x 10⁵ n/s. Determine the total neutron production rate in the reactor when k_eff = 0.991.

 

Question 5

The neutron monitoring system of a reactor indicates a count rate of 20 cps and the reactivity is -1500 pcm. Determine what the neutron level will be after a positive reactivity insertion of 800 pcm from the withdrawal of control rods.
