Ok guys, I'm gonna try to do a realistic BWR reactor, I will use as less indestructible parts as possible. It will contain the following (please read before commenting):

REACTOR CHARACTERISTICS

Reactor type: BWR.
Rods position: Up for more power and down for less power.
Reactor material: TTAN.
Fuel rods type: Uranium (URAN) and Boyle gas (BOYL).
Optimal/stable reactor temperature: 200-300°C.
Reactor moderator type: WATR or DSTW (not sure which one of both).
Turbine type: Steam+minimum pressure required to generate power.


INSTRUMENTS AND INDICATORS

- Water temperature indicator
- Fuel rods temperature indicators
- Reactor pressure indicator
- Reactor water level indicator
- Condenser water level indicator
- Control rods position
- Turbine pressure indicator
- Alarms panel

REACTOR CONTROLS


General Reactor Controls
- Control rod selection panel
- Control rods position mover
- Pressure valves

MCCP Controls
- Feedwater pumps 1 and 2+Feedwater valves
- Reactor water drain valves

Turbine Controls
- Main turbine valve
- Bypass and steam valve
- Turbine Trip/Stop valves
- Turbine power generation

Condenser Controls
- Recirculation valves
- Condenser drain valves

Electrical Panel
- Startup transformer
- Main bus (powered when turbine runs)
- Diesel-powered auxiliar Buses 1 and 2

Emergency Safety Systems
- SCRAM: It will trip the reactor, drop out the control rods, trip the turbine and relief the steam and pressure (shutdown the reactor).
- LPCI (Low Pressure Coolant Injection): It will inject water to the reactor. Necessary when water level is low.
- Emergency Steam Relief: It will eject the steam and pressure.
- Diesel-powered auxiliar buses 1 and 2: They will generate auxiliar power in case of the startup transformer breaks or offsite power gets lost.

PROGRESS

    Part 1: Planification (completed)
    Part 2: Investigation (completed)
    Part 3: Physics testing (completed)
→ Part 4: Building a prototype
    Part 5: Testing the prototype
    Part 6: Building the final version
    Part 7: Testing
    Part 8: Deco-coloring the save
    Part 9: Final testing
    Part 10: Release

NOTE: The reactor characteristics may be changed.

I hope you like it, a support may be helpful for me to continue this project (not obligatory), Have a nice day.
