Westinghouse SMR Features
Pressurizer
Integration into reactor vessel head eliminates the need for a separate componentSteam Generator
Achieves a compact physical envelope with an innovative approach to steam separationReactor Coolant Pumps
Proven, horizontally-mounted axial-flow pumps provide the driving head for the reactor coolant system while eliminating the need for pump seal injectionReactor Vessel Internals
Based on the AP1000® design, the reactor vessel internals are modified for the smaller core and to provide support for the internal control drive rod mechanismsReactor Core
