Flow Accelerated Corrosion（FAC） usually occurs at 90-230 ℃

but FAC also could occur at lower temperature.Although this phenomenon is not common

the piping wall thickness degraded at low temperature may cause the turbine shutdown

which would take a lot of maintenance costs. The damage caused by low temperature FAC in the nuclear power plant conventional island is introduced

that confirmed the low temperature FAC could appear in the 50 ℃ condensate system. Then

this paper recommended some measurements to prevent and detect low temperature FAC in a nuclear power plant pipeline.
