Reactor Theory (Nuclear Parameters)DOE-HDBK-1019/2-93CONTROL RODSThe following exercises are intended to reinforce an understanding of the concepts of integraland differential rod worth.Example 1:Using the integral rod worth curve provided in Figure 11, find the reactivity inserted bymoving the rod from 12 inches withdrawn out to 18 inches withdrawn.Figure 11 Rod Worth Curves for Example ProblemsSolution:The integral rod worth at 12 inches is 40 pcm and the integral rod worth at 18 inches is80 pcm.
