OBJECTIVES
DOE-HDBK-1019/2-93
Reactor Theory (Nuclear Parameters)
TERMINAL OBJECTIVE
5.0
Without references, DESCRIBE how control rods affect the reactor core.
ENABLING OBJECTIVES
5.1
DESCRIBE the difference between a "grey" neutron absorbing material and a "black"
neutron absorbing material.
5.2
EXPLAIN why a "grey" neutron absorbing material may be preferable to a "black"
neutron absorbing material for use in control rods.
5.3
EXPLAIN why resonance absorbers are sometimes preferred over thermal absorbers as
a control rod material.
5.4
DEFINE the following terms:
a.
Integral control rod worth
b.
Differential control rod worth
5.5
DESCRIBE the shape of a typical differential control rod worth curve and explain the
reason for the shape.
5.6
DESCRIBE the shape of a typical integral control rod worth curve and explain the reason
for the shape.
5.7
Given an integral or differential control rod worth curve, CALCULATE the reactivity
change due to a control rod movement between two positions.
5.8
Given differential control rod worth data, PLOT differential and integral control rod
worth curves.
