MSR Upgrades

Moisture Separator Reheater – MSR

MSR UPGRADE OPTIONS

Existing MSR Refurbishment
Here, the functioning internals – reheaters and moisture separation systems – are selectively replaced by advanced-technology components within the existing internal MSR structure. While this is probably the least expensive approach, it produces less than full utilization of modern MSR technology.

Full MSR internals redesign and reconstruction
Where the reconstruction approach is indicated, the existing MSR shells are completely gutted. Advanced MSR component technology and improved structural design can be used to produce maximum MWe gain through near 100 percent moisture separation, minimum TTD (resulting in maximum superheat to the LP turbine) and lowest attainable pressure drop.

Complete MSR Vessel Replacement
As well as using modern MSR technology entirely replacing the MSR vessel allows the MSR shell size to be optimized. This approach is particularly attractive where excessive internal steam velocities have produced flow-assisted corrosion (FAC) damage.
