Given an AGR operating under specific conditions, calculate the heat absorbed by the coolant and thermal efficiency of the reactor if the electrical output is 200 MWe. (show the equation and numerical application used)
The following data is provided:
Core inlet temperature: 300° C
Core outlet temperature: 650° C
Pressure: 40 bar
Mass flow rate of the coolant: 1200 kg/s
Specific heat capacity of CO₂: 1.2 kJ/kg·K
