Background
Westinghouse has been providing its Flux Mapping System (FMS) for pressurized water reactors (PWRs) since the beginning of the commercial nuclear power industry. The FMS provided by Westinghouse and systems based on the Westinghouse technology and design are in operation in nearly 50 percent of the operating plants worldwide. Replacement systems and upgrades also have been provided to PWR FMSs.
Description
Westinghouse and Triumph Controls are a long-established original equipment manufacturer (OEM) team providing flux mapping, movable incore detector system expertise. With a teaming agreement in place, the two companies are positioned to provide next-generation flux mapping solutions to customers.
The total FMS consists of:
- Flux Mapping Console (FMC)
