Unit 3 is equipped with a Babcock & Wilcox supercritical steam generator operating at 3,500 psig with 1,000F main and reheat. The 1,150-MW steam turbine is a General Electric cross-compound design ...

Similarly, a turbine wheel was printed in resin as well, with the steam outlet pointed directly at its vanes. To really stress test the parts, more steam was required.

As the energy available is only kinetic energy, the Pelton wheel is an example of an impulse turbine. Such impulse turbines do not require an enclosed case, whereas Radial flow turbines have very ...
