In this paper, three-dimensional neutronic calculations were performed in order to calculate the dependencyof CRW on the temperature of fuel and moderator and the moderator void. Calculations wereperformed using the known MTR_PC computer codes in the core configuration 61 of TRR. The dependencyof CRW on the fuel temperature in the range of 20e340 C and the moderator temperature ofeach control rods were studied. Based on the positions of the control rods, the calculations were performedin three different cases, named case A, B and C. By the results, the worth of each control rodsincreases by increasing of the coolant temperature in all methods, however, the total CRW is somewhatindependent of the fuel temperature. In addition, the results showed that the variation of CRW versusdensity depends on the positions of the control rods and the most change in CRW in the coolant temperature,20e100 C (279 pcm), belongs to SR4. Finally the effect of void on CRW was studied fordifferent void fraction in coolant. The most worth change is about $2 for 40% void fraction related to SR1and SR3 in case B. For 40% void fraction, the total CRW increases about $7.5, $6 and $7 in cases, A, B and C,respectively
