What is the purpose of containment penetration seals and gaskets?

• A. To allow unrestricted air flow
• B. To provide a check for fuel temperature
• C. To maintain confinement by preventing leakage through penetrations with robust seals
• D. To monitor radiation fields

Answer: (C)

Containment penetration seals and gaskets exist to keep the confinement barrier intact where pipes, cables, and other penetrations pass through. These openings could become leakage paths, so the seals create a leak-tight boundary that can withstand pressure, temperature changes, radiation, and movement, including thermal expansion and seismic shifts. By maintaining a robust seal around each penetration, they help prevent any radioactive material from escaping the containment. They aren’t about allowing air flow, checking fuel temperature, or monitoring radiation fields; their role is to preserve confinement by eliminating leakage through penetrations.
