I'm studying about Thermal Hydraulic. When i read book :"NUCLEAR SYSTEMS I Thermal Hydraulic Fundamentals" - Neil E. Todreas and Mujid S. Kazimi.(adsbygoogle = window.adsbygoogle || []).push({});

I don't understand about : calculate "Minimum critical power ratio" & calculate "Pumping power" in problem:

a) Calculate the minimum critical power ratiofor a typical 10 MWe BWR operating at 100% power using the data in Tables 1-2, 1-3, and 2-3 . Assume that:

1. The axial linear power shape can be expressed as

q'(z) = q'ref*exp (- az/L )sin (pi*z/L)

where a = 1.96. Determine q'ref such that qmax = 44 kW/m

2. The critical bundle power is 93 19kW.

b) Calculate the pumping powerunder steady-state operating conditions for a typical PWR reactor coolant system. Assume the following operating conditions:

Core power = 38 17 MWt

detal Tcore = 31 °C

Reactor coolant system pressure drop = 778 kPa (1 13 psi)

can anyone help me solve the problem ? or guide me solve the problem. thank!
