DYNAMIC PORT® Oil Sensing Upgrade

The oil level indicating system on Westinghouse reactor coolant pump (RCP) motors monitors the oil inventory within the bearing oil reservoir. The concept behind the original system used on the lower oil reservoir on RCP motors was a simple transference of oil level from inside the bearing oil reservoir to an alarm reservoir and sight glass that is external to the lower oil reservoir.

Engineered Leak Rate No. 1 Seal for Reactor Coolant Pumps

Reactor coolant pump (RCP) control leak-off seal performance is heavily influenced by a variety of plant and environmental conditions that can directly impact the RCP seal leak-off rate, the dominant variable used to evaluate seal performance. Unplanned forced outages or an extension of an outage can result if leak-off rates approach their lower or higher operating limits.

SHIELD® Passive Thermal Shutdown Seal for Reactor Coolant Pumps

Westinghouse developed the SHIELD® passive thermal shutdown seal as a passive means of protecting the reactor core. It prevents a loss of reactor coolant system (RCS) water inventory should an event occur that causes a loss of all seal cooling. The SHIELD passive thermal shutdown seal is proven to significantly reduce or eliminate leakage from the reactor coolant pump (RCP) seal with no operator action, power or control logic required.
