Exercise 15.7

Suppose that the LMFBR in the previous exercise (Exercise
15.6) has an actual thermal efciency of 40%. What is the electrical power
output of this power plant, and if it is a loop-type LMFBR, how many different
cooling loops does it have?

Exercise 15,6’

The energy content (or the enthalpy) of liquid sodium
entering the core of an LMFBR at 395.0°C is 600 kJ/kg, and the energy content
(or enthalpy) of liquid sodium leaving the core of an LMFBR at 545.0°C is 790
kJ/kg. If the mass ow rate through the core is 15,700 kg/s, what is the
thermal power output of this LMFBR?
