Nuclear plants get a clearer path to use fiber optics in safety systems
What happened
The US nuclear regulator is asking for public comment on a new guide. This guide explains how to qualify fiber-optic cables and connections for use in nuclear power plant safety systems.
Why it matters
Nuclear facilities have traditionally relied on copper wiring for safety systems. This guide makes it easier for them to adopt fiber optics, which are immune to electromagnetic interference and can transmit data faster. It is a small step towards modernizing the underlying infrastructure of nuclear power plants.
The signal
Watch for whether nuclear facilities start proposing fiber optic installations in their safety systems in future upgrade plans or new reactor designs.
