Steam generator (nuclear power) - Wikipedia

A steam generator's heat-exchange tubes have an important safety role, because they separate radioactive and non-radioactive fluid systems. (The primary coolant becomes briefly radioactive from its exposure to the core, and also has trace amounts of longer-lived radioactive isotopes dissolved in it, such as dissolved atoms of iron from pipes.)

PROPER SIZING AND INSTALLATION FOR STEAM SYSTEM SAFETY VALVES
