OBJECTIVESDOE-HDBK-1019/2-93Reactor Theory (Nuclear Parameters)TERMINAL OBJECTIVE5.0Without references, DESCRIBE how control rods affect the reactor core.ENABLING OBJECTIVES5.1DESCRIBEthe difference between a "grey" neutron absorbing material and a "black"neutron absorbing material.5.2EXPLAINwhy a "grey" neutron absorbing material may be preferable to a "black"neutron absorbing material for use in control rods.5.3EXPLAINwhy resonance absorbers are sometimes preferred over thermal absorbers asa control rod material.5.4DEFINEthe following terms:a.Integral control rod worthb.Differential control rod worth5.5DESCRIBEthe shape of a typical differential control rod worth curve and explain thereason for the shape.5.6DESCRIBEthe shape of a typical integral control rod worth curve and explain the reasonfor the shape.5.7Given an integral or differential control rod worth curve, CALCULATE the reactivitychange due to a control rod movement between two positions.5.8Given differential control rod worth data, PLOT differential and integral control rodworth curves.NP-03Page xiiRev. 0
