Containment Penetration Sleeve from Japan
A containment penetration sleeve is a pressure-tight, seismic-qualified assembly that allows piping and cabling to pass through the reactor containment structure while maintaining the integrity of the containment barrier. It is an essential safety component of a nuclear reactor, as it ensures the containment remains leak-tight under normal and accident conditions. This sleeve is classified under tariff item 8401.40.00 as a part of nuclear reactors.
