Abstract
A containment seal seals a cable or tube to an opening accessing a containment vessel. The containment seal includes a lower body that attaches over the opening into the containment vessel. The cable or tube is inserted through a hole that extends axially through an upper body of the containment seal. Compression fittings are attached to the top and bottom ends of the upper body sealing the cable inside of the upper body. The cable sealed inside of the upper body in inserted through the lower body and into the opening accessing the containment vessel and a lower portion of the upper body is seated into the opening formed in the lower body. A retaining device compresses the upper body down against the lower body forming a seal between the upper body and lower body.

A nuclear reactor containment seal for use sealing an opening of a containment vessel, comprising:
- a lower body having an opening positionable to align with the opening of the containment vessel;
- an upper body including a through-hole, with the through-hole of the upper body and the opening of the lower body configured to receive a cable or tube to extend therethrough, the upper body having a bottom tubular section configured to insert at least partially down into the opening in the lower body, and a middle section that extends up and radially out from the bottom section and forms a bottom surface that seats onto a top surface of the lower body, the middle section having a threaded side surface;
- and
- a nut retained by the lower body and configured to threadably engage the threaded side surface of the upper body to hold the upper body down against the lower body, forming a sealed connection between the upper body and the lower body.

- a nut retained by the lower body and configured to threadably engage the threaded side surface of the upper body to hold the upper body down against the lower body, forming a sealed connection between the upper body and the lower body;
- a first test port including a first channel that extends from an exterior of the upper or lower body into an interior of the upper or lower body between two of the O-ring channels;
- and
- a second test port including a second channel that extends from the exterior of the upper or lower body into the hole that receives the cable or tube.
