Unitary resinous penetration assembly

Claim 1

An electrical penetration module for sealingly passing an electrical conductor through a containment wall comprising a right circular cylindrical unitary body of chemically stable, radioactive resistant, gas impervious, compressive setting epoxy resin potting material disposed about a porous, concrete disc-like spacer leak monitoring means, with at least one electrical conductor extending longitudinally through the disc-like spacer and the cylindrical body about the spacer, which conductor is compressively sealed to the cylindrical body along a substantial portion of the body length, with an aperture channel provided in the cylindrical body from the embedded spacer to the exterior surface of the cylindrical body, with O-ring receiving grooves formed in the exterior surface of the cylindrical body on either side of the aperture channel for sealably mounting the module, and a metallic clamping ring embedded in the exterior surface of the cylindrical body extending about the cylindrical body on the outboard side of the leak monitoring means and the O-ring receiving grooves.
