OBJECTIVES
TERMINAL OBJECTIVE
3.0
Without references, EXPLAIN the production process and effects on fission of prompt
and delayed neutrons.
ENABLING OBJECTIVES
3.1
STATE the origin of prompt neutrons and delayed neutrons.
3.2
STATE the approximate fraction of neutrons that are born as delayed neutrons from the
fission of the following nuclear fuels:
a.
Uranium-235
b.
Plutonium-239
3.3
EXPLAIN the mechanism for production of delayed neutrons.
3.4
EXPLAIN prompt and delayed neutron generation times.
3.5
Given prompt and delayed neutron generation times and delayed neutron fraction,
CALCULATE the average generation time.
3.6
EXPLAIN the effect of delayed neutrons on reactor control.
