1. The problem statement, all variables and given/known data The last part of my question reads: Give the equations you would use to determine reactor thermal output if the plant is to produce 1000 MWe. All expressions for work and heat transfer rate should be expressed in terms of the appropriate mass flow rate ratios. 2. Relevant equations Efficiency = Wnet/Qh 3. The attempt at a solution I have been given turbine efficiency and pump efficiency. Also, assume I have found the enthalpy at each state point and was subsequently able to determine the net work and heat addition to the system. I feel like I need to determine the mass flow rate by dividing 1000 MWe by Wnet and then plug that value in to the equation for Qh to get thermal output.
