TERMINAL OBJECTIVE
2.0
Given the necessary information and equations, DESCRIBE how power changes in a
reactor that is near criticality.
ENABLING OBJECTIVES
2.1
DEFINE the following terms:
a.
Reactor period
b.
Doubling time
c.
Reactor startup rate
2.2
DESCRIBE the relationship between the delayed neutron fraction, average delayed
neutron fraction, and effective delayed neutron fraction.
2.3
WRITE the period equation and IDENTIFY each symbol.
2.4
Given the reactivity of the core and values for the effective average delayed neutron
fraction and decay constant, CALCULATE the reactor period and the startup rate.
2.5
Given the initial power level and either the doubling or halving time, CALCULATE the
power at any later time.
2.6
Given the initial power level and the reactor period, CALCULATE the power at any
later time.
2.7
EXPLAIN what is meant by the terms prompt drop and prompt jump.
2.8
DEFINE the term prompt critical.
2.9
DESCRIBE reactor behavior during the prompt critical condition.
2.10
EXPLAIN the use of measuring reactivity in units of dollars.
