The neutron generation time of a particular reactor is 1.3 ms.The reactor is generating energy at the rate of 1200.0 MW.To perform certain maintenance checks, the power level must temporarily be reduced to 350.00 MW. It is desired that the transition to the reduced power level take 2.6000 s. To what (constant) value should the multiplication factor be set to effect the transition in the desired time?
A reactor operates at 400 MW with a neutron generation time of 30.0 ms. If its power increases for 5.00 min with a multiplication factor of 1.0003, what is the power output at the end of the 5.00 min?
5. The neutron flux in a bare spherical reactor of radius 50 cm is given by sin 0.0628r = 5 x 1013 1000 mor -neutrons/cm²-sec, where r is measured from the center of the reactor. The diffusion coefficient for the system is 0.80 cm. (a) What is the maximum value of the flux in the reactor? (b) Calculate the neutron current density as a function of position in the reactor. (c) How many neutrons escape from the reactor per second? leakage (@)&=0
