WebAug 4, 2024 · At present, most pressurized water reactor nuclear power plants in China use shaft seal coolant pumps. Shaft seal is an important component of the coolant pump, which ensures that the radioactive reactor coolant will not leak out through the coolant pump under normal working conditions. WebA test program has been conducted that subjects full-scale seal cartridges to typical pressurized water reactor (PWR) coolant system steady-state and transient operation conditions including associated dynamic shaft motions. A special test segment was developed to evaluate seal operation under station blackout conditions.
WebThe reactor has two independent cooling circuits, each having four main circulating pumps (three operating, one standby) that service one half of the reactor. The cooling water is fed to the reactor through lower water lines to a common pressure header (one for each cooling circuit), which is split to 22 group distribution headers, each feeding ... http://large.stanford.edu/courses/2024/ph241/chaffin2/
WebThe reactor coolant pumps circulate reactor coolant through the reactor vessel to the steam generators for heat removal and return it to the reactor vessel. The pump is a single-stage centrifugal unit of vertical type, which has 12,000 horse power. To assure leak-tightness of the shaft, the mechanical seal type is taken in WebThe temperature of the reactor coolant water is typically in the range of from approximately 500° to 600° F. which is too hot to also use to cool the motor and bearings of the cleanup pump....
