backfit

Modify existing equipment

Backfit means to retrofit or modify existing equipment, systems, or structures to incorporate new features, meet updated standards, or improve safety.

The term appears most often in nuclear power and engineering contexts, where older facilities must be upgraded to comply with current regulations: The plant was required to backfit new safety systems after the accident.

Backfitting can be costly and complex, since changes must work within constraints of the original design.
