Q
Function
A
- Under normal operating conditions, the S/Gs provide sufficient heat transfer capacity to convert feedwater to steam, as required, for the turbine and auxiliaries during all modes of operation.
- Provides sufficient heat removal capacity to allow the main steam system to remove the total heat generated in the RCS during accident conditions.
2
Q
Steam Flow Limiter
7 Ventruis
A
- Protect the containment from exceeding its design pressure and prevent excessive cooldown rate of the RCS by limiting the steam flow that can result from a MSLB.
- Does not effect normal operations.
3
Q
Swirl Vane Moisture separator
A
- 1st stage moisture separation occurs in the swirl vanes where the velocity of the steam-water mix is converted to a rotary velocity, creating a centrifugal effect.
- 3 swirl vane assemblies per s/g
- Separated water is drained back to the downcomer where it combines with feedwater for another pass
4
Q
Quatrefoil tube
how many? does what?
A
-6 quatrefoil tube support plates provide lateral support, and minimize vibration
5
Q
What Rx trip is associated with S/Gs
A
-Lo-lo level (16%)
