Simulate operations of Pressurised Water Reactor and attached Steam Turbine for Power Generation.
This simulation represents a rather basic model of a 3500MW(thermal) Pressurised Water Nuclear Reactor and associated Steam Turbine for power generation. It is not meant as a complete simulator training system, but just as a proof of concept of what is possible.
It is still very much a work in progress but currently can simulate operation of a PWR reactor from mode 5 condition (cold shut down) until mode 1 (power operations) and then up to full load. Some of the areas/items already implemented include;
- 4-loop PWR reactor.
- Pressuriser with heater and spray controllers.
- Reactor Source/Intermediate/Power range flux meters.
- Chemical and Volume Control system (CVCS) with borating/dilution control.
- Estimation of criticality.
- Effects of all components +/- of reactivity (although still working to get the negative reactivity effects of Iodine/Xenon accurate).
- 4 x Steam Generators.
- Emergency Cooling Water system, with cold leg accumulator, LP/HP Emergency cooling pumps and containment spray pumps.
- Alarm/Event, Trip/SCRAM and Runback systems.
- simplified Condensate and Feedwater Systems.
- simplified Main Cooling Water, Service Water and Closed Cooling Water systems.
- simulation of various faults (Fallen rod, Ejected rod, Turbine trip, RCP trip and Runback, LOCA (Loss of Coolant Accident).
Minimum System requirements macOS are;
- Intel or ARM processor
- macOS 10.14 (Mojave)
