packageExercise2NuclearReactor

Information

This Test package contains 3 sequences of steps for constructing a nuclear reactor.

• Exercise2NuclearReactor.Adiabatic uses the Adiabatic model and the InverseBlockConstraints model.
• Exercise2NuclearReactor.AdiabaticPseudoInversion uses the Adiabatic model and avoids the use of the InverseBlockConstraints model using pseudoInversion "controllers".
• Exercise2NuclearReactor.Polytropic uses the PolytropicPerfectGas model which requires less use of the InverseBlockConstraints model.

English problem description

A closed-cycle gas turbine process is used to cool a high-temperature reactor. Helium (ideal gas, R = 2077.3 J/(kg·K), gamma = 1.66) starting from 780 K, 70.0 bar is heated isobarically by the reactor waste heat of 6.00 MW up to a temperature of 1180 K.

The helium then expands in the adiabatic turbine1 (eta_is = 0.94) to 1110 K, followed by expansion in the adiabatic turbine2 to 52.4 bar, 1060 K, and finally expansion in the diabatic turbine3 to 844.5 K.

turbine1 drives compressor1 and turbine2 drives compressor2 via shafts, while turbine3 drives the generator (3015 kW). All three shafts operate with a mechanical efficiency of eta = 0.95.

In the isobaric, externally adiabatic heat exchanger (heatExchangerHotSide) and in the isobaric cooler2, the helium is cooled to 285 K. In the adiabatic compressore2 it is first compressored and in the compressor1 again compressred to 70.0 bar, 376 K (eta_is = 0.96) before being heated in heatExchangerColdSide.
