Turbine Trip
a turbine trip is when the turbine stops, which means we are no longer receiving water and lose the ability to cool.
this can be identified by these conditions:
- the current flow rate is 0 mB/t and it should not be
- can initially catch this by detecting a 0 flow rate with a non-zero input rate, but eventually the steam will fill up
- can later identified by presence of steam in tank with a 0 flow rate

Turbine Trip
a turbine trip is when the turbine stops, which means we are no longer receiving water and lose the ability to cool.
this can be identified by these conditions:
- the current flow rate is 0 mB/t and it should not be
- can initially catch this by detecting a 0 flow rate with a non-zero input rate, but eventually the steam will fill up
- can later identified by presence of steam in tank with a 0 flow rate
