Q1: What materials handle 600°C sodium coolant pipes?
A1: 316 stainless steel is standard for sodium systems. The pipes incorporate trace heating to prevent freezing. Special argon cover gas systems maintain oxygen-free conditions. These measures prevent corrosive sodium oxide formation.
Q2: How are lead-bismuth eutectic pipes protected?
A2: Oxygen control maintains protective oxide layers. The pipes use low-silicon steels to prevent wetting issues. These solutions enable advanced nuclear and industrial systems.
Q3: What are the challenges in lithium-cooled fusion blanket pipes?
A3: They must withstand neutron irradiation while preventing tritium loss. Special permeation barriers are under development. These materials represent the cutting edge of fusion technology.
Q4: Why are electromagnetic pumps used for liquid metal pipes?
A4: They provide contactless pumping without moving parts. The designs prevent vibration and wear issues. These advantages are critical for reliable long-term operation.
Q5: How are liquid metal pipe leaks detected?
A5: Spark plug sensors identify sodium fires. Mass spectrometers detect cover gas changes. These systems provide early warning of integrity loss.
