An electrical penetration assembly for a nuclear reactor containment wall in which solid copper conductors are removably mounted into the penetration canister from outside the containment wall. Each conductor is mounted in a feedthrough pipe by glass-sealed headers, one of which has a metal bellows that permits axial expansion of the conductor when it is subjected to elevated temperatures.
