 Westinghouse Electric Co. Demonstrates Nuclear Power Shutdown Seal

Westinghouse Electric Co. demonstrated that its shutdown seal performs as designed in a nuclear power plant.
The Westinghouse Generation III Shield Shutdown Seal was removed from service at Beaver Valley Unit 2 for the static activation test after one fuel cycle, which began in spring 2014. The test was performed at the Westinghouse Science and Technology Center in Pennsylvania, with First Energy Nuclear Operating Co., Pressurized Water Reactor Owners Group and the U.S. Nuclear Regulatory Commission (NRC) in attendance.
The seal thermally activates and reduces reactor coolant pump flow to less than one gallon per minute during station blackout conditions. The seal is expected to help customers comply with NRC’s FLEX requirements.
