Auxiliary/Backup Water Control

[MikaylaFischler]

Support enabling water to either the reactor or the boiler when water levels drop. This can occur on burn rate increases and during initial start. This would activate much earlier than emergency coolant, with emergency coolant being the last line of defense against a meltdown due to loss of coolant.

This would only be implemented for water, auxiliary sodium would not solve the boiler water level low problem. It would also be very challenging to fit into the flow monitor display.

Update: Additionally, auxiliary sodium would end up filling the cooling loop with sodium, since it only gets lost on overfilling. Water should be all that is needed in both water cooled and sodium cooled systems.
