Abstract
Abstract A modular electrical penetration assembly designed for bringing electrical conductors through the containment vessel of a nuclear power plant. The modular assembly is factory assembled, with or without a leak detector monitoring space, and is adapted for ready field installation. A generally tubular enclosure defining metal member has at least one electrical conductor longitudinally extending therethrough, with a pair of axially aligned seal shroud means disposed within the enclosure about the electrical conductors. The shroud means is closely spaced from the tubular metal member and sealingly connected thereto at one end. A radiation resistant, chemically stable, gas impervious resinous potting material substantially fills the enclosure and upon thermal setting in place provides a compression seal along the conductor and at the seal shroud means.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
158 words
An electrical penetration assembly comprising: a. an enclosure defining metal member; b. a pair of axially aligned annular seal shroud means disposed within the enclosure defined by the metal member, each of said annular seal shroud means comprising a sealing end which is sealingly connected to the interior surface of the metal member, and a free end which is spaced from the enclosure defining metal member which free end has an outer surface generally parallel to the interior surface of the metal member; c. at least one longitudinally extending electrical conductor extending through said enclosure defined by said metal member, and passing through both of the annular seal shroud means; d. a chemically stable, radioactive resistant, gas inpervious, compressive setting, resinous potting material substantially filling the enclosure defined by said metal member, and providing a compression seal along and about the conductor, and about the outer surface of the free end of each of the seal shroud means.
Claim 2
Dependent Claim
158 words
An electrical penetration assembly comprising: a. an enclosure defining metal member; b. a pair of axially aligned annular seal shroud means disposed within the enclosure defined by the metal member, each of said annular seal shroud means comprising a sealing end which is sealingly connected to the interior surface of the metal member, and a free end which is spaced from the enclosure defining metal member which free end has an outer surface generally parallel to the interior surface of the metal member; c. at least one longitudinally extending electrical conductor extending through said enclosure defined by said metal member, and passing through both of the annular seal shroud means; d. a chemically stable, radioactive resistant, gas inpervious, compressive setting, resinous potting material substantially filling the enclosure defined by said metal member, and providing a compression seal along and about the conductor, and about the outer surface of the free end of each of the seal shroud means.
Claim 3
Dependent Claim
17 words
The electrical assembly penetration specified in claim 1, wherein the enclosure defining metal member is generally tubular.
Claim 4
Dependent Claim
38 words
The electrical penetration assembly specified in claim 2, wherein circumferential sealing means are disposed about the exterior surface of said tubular metal member, which sealing means are adapted to seal the assembly against a penetration assembly receiving structure.
Claim 5
Dependent Claim
39 words
The electrical penetration assembly specified in claim 2, wherein the resinous potting material has a coefficient of expansion greater than that of the tubular metal member, and which resinous potting material shrinks upon curing thereby creating said compression seal.
Claim 6
Dependent Claim
39 words
The electrical penetration assembly specified in claim 2, wherein a centrally located monitoring chamber is defined within the penetration assembly by spacing the potting material, and providing an aperture through said tubular metal member interconnected with said Monitoring chamber.
Claim 7
Dependent Claim
50 words
The electrical penetration assembly specified in claim 5, wherein a pair of insulator disks are centrally located within the volume defined by the tubular metal member, which insulator disks are spaced apart in generally parallel relationship to define the monitoring chamber therebetween, said insulator disks having conductor passing apertures therethrough.
Claim 8
Dependent Claim
65 words
The electrical penetration assembly specified in claim 1, wherein the metal member enclosure comprises a centrally located annular sealing header and tubular extensions sealed to each side of the sealing header, circumferential sealing means provided in the exterior surface of the sealing header, with each annular seal shroud means having an outwardly directed extension at one end which is sealably connected to the sealing header.
Claim 9
Dependent Claim
101 words
The electrical penetration assembly specified in claim 1, wherein the metal member enclosure comprises a generally tubular member with an inboard and outboard bulkhead member sealed to each end of the tubular member, circumferential sealing means provided in the exterior surface of the central portion of the tubular member, with each annular seal shroud means sealingly connected to the interior surface of the respective inboard and outboard bulkhead members and extending toward the central portion of the tubular member, and at least one aligned aperture provided in each of the inboard and outboard bulkhead members for passing an electrical conductor therethrough.
