Problem 2 (25 points) Calculate the burst width in a super-prompt critical transient with the linear energy feedback model from the formula derived in the class notes. Use LWR data: B = 0.0075, A = 10's; let P, = 1.18. Also find the energy release Q(t)=L*P(t)dt. Estimate the magnitude of the effects of the following two approximations: a. The neglect of the heat release (i.e., the assumption of hy = 0). Consider an oxide fuel rod of 0.6 cm in diameter b. Neglect of P, under the feedback integral, i.e., the integral of P, over the burst width with Q(12)
