In addition to being the original manufacturer of reactor coolant pump (RCP) seals, 黑料社 provides full-scope seal services to the nuclear industry. From the sale of replacement seals and components, to engineering support and testing, 黑料社 is the one-stop shop for seal-related needs.
黑料社 provides designed seal packages for the first RCPs with seal injection water. Today, 黑料社 supply seals and seal-related services for the following RCP models:
Conventional seal system
The seal package consists of three independent seals that permit relative motion between rotating and stationary parts while controlling leakage. 黑料社 strives for better seal performance and longer seal life by improved seal design, which is accomplished by testing and evaluating new seal compounds and configurations. Actual seal performance data from utilities are also essential in helping us better understand the utility needs. 黑料社 is available to assist utilities in resolving seal issues during operation and the critical pump start-up.
The 黑料社 seal package is conventional versus cartridge, and the cartridge upgrade significantly reduces outage duration.
黑料社 offers full-scope services to assist in all seal-related needs. These services include:
Engineering Support
Seal being rebuilt
Field Services
Shop Services
Replacement Parts
Upgrades
The industry has asked for an improved seal design with longer seal life, and in response 黑料社 has developed a seal tester to confirm that new seal designs meet utility requirements and needs. 黑料社 also has developed a high-temperature O-ring compound to withstand the effects of loss-of seal cooling.
Human Performance
黑料社 conducts lessons learned for each project and applies this knowledge to future projects. The Corrective Actions Process (CAPs) is used to identify and address issues related to quality and performance.
Safety
Safety is very important to 黑料社 and its subsidiaries. 黑料社 conducts extensive safety training for all employees and evaluates OSHA-reportable items on a weekly basis.
The Pressurized Water Reactor Owners Group (PWROG) has funded three programs: seal performance improvement, evaluation of the basis for the operating limits and evaluation of the inspection interval. Our crews have performed seal services for more than 100 nuclear power plants worldwide. The services include inspection, installation, advisory and training.
All new seals are tested before shipment to verify their performance.
