Nuclear power - Coupling Corporation of America

Coupling Corporation’s flexible couplings and Anderson Clamp Hubs meet the Nuclear Power Industry’s need for reliability, dependability and maintenance free performance. Our numerous nuclear installations continue to perform flawlessly year after year.

Although CCA does not have an official 10 CFR 50 Appendix B program, our quality program is designed to that standard. Therefore, it is very easy for our customers to perform Commercial Grade Dedication on our products to use them in Safety Related applications.

As plant budgets are under continual pressure, reduction of manpower is a constant concern. For many plants, the gear couplings that were part of the original design require a large amount of manpower for preventative maintenance for things like greasing and wear checks. Unfortunately, as those tasks are cut from the schedule, the equipment runs the risk of unexpected failure. This is why switching to non-maintenance CCA couplings makes perfect sense. It eliminates the manpower needed to perform PM’s and it makes installation and removal quicker during outages.
