Reactor Theory (Reactor Operations)DOE-HDBK-1019/2-93OBJECTIVESTERMINAL OBJECTIVE1.0Given the necessary information and equations, EXPLAINhow subcritical multiplicationoccurs.ENABLING OBJECTIVES1.1DEFINEthe following terms:a.Subcritical multiplicationb.Subcritical multiplication factor1.2Given a neutron source strength and a subcritical system of known keff, CALCULATEthe steady-state neutron level.1.3Given an initial count rate and keff, CALCULATE the final count rate that will resultfrom the addition of a known amount of reactivity.1.4Given count rates vs. the parameter being adjusted, ESTIMATE the value of theparameter at which the reactor will become critical through the use of a 1/M plot.Rev. 0NP-04Page v
