Valves
The valves in the LP SCR system are used for the different operation modes. The LP SCR
system has the valves that follow:
○
V1 - reactor inlet valve
○
V2 - reactor outlet valve
○
V3 - reactor bypass valve
○
V4 - turbine bypass valve
The turbine bypass valve (V4) is also used for other functions of the ECS, for example for
low-load tuning (LLT) or for steam production control (SPC).
