Reverse Engineering Annunciator Relays at Susquehanna: Customer Success Story
October 23, 2023
Organization:
Talen Energy is an independent power producer founded in 2015. Its Susquehanna plant produces 63 million kilowatt hours per day and has been in operation since 1983.
Challenge:
Obsolescence is a pressing problem at today’s nuclear power plants. In many cases, original analog parts such as the Panalarm 70-X11 relay are in limited supply, or may no longer be available from surplus vendors.
Solution:
Curtiss-Wright reverse-engineered a replacement relay known as the NUS-70-X11, which replicates the basic function of the Panalarm 70-X11 while significantly improving the longevity and maintainability of the unit.
Results:
Reverse engineering the old relays rather than installing new annunciator panels and brand new relays has the potential to save Talen Energy an estimated $9.5 million.
