About this file

This is an engineering drawing and technical specification for a CDM Outsert Shielding component prepared by Norfolk Naval Shipyard, Code 2370 Reactor Servicing. The document provides detailed dimensional specifications and fabrication requirements for a magnetic tungsten-impregnated rubber shielding piece designed to fit around standard 8-inch Schedule 40 pipe.

The outsert shield must be manufactured from magnetic tungsten-impregnated rubber shielding with a minimum density of 7 g/cc and a Tenth-Value Layer (TVL) of 2.00 inches or greater, per APL specification. Each individual piece must weigh less than 40 pounds, and six pieces are required per position to fit together around the pipe with no gaps present. The magnetic layer must be applied to the interior surface at minimum, with possible application to the 30-degree side cuts if feasible. Each piece must be labeled externally with "RF-7445" and its weight in a suitable color other than yellow or magenta. The drawing shows detailed isometric and front views with specific dimensions including radii (R4.31, R5.50, R5.75), angles (30 and 60 degrees), and a total length of 15.00 inches. The document was originally issued on July 7, 2025, by engineer A. Davidson and approved by Samuel Bower (SOF) on July 8, 2025.
