About this file
This is a technical drawing specification document for an RSMA Disposal Box (Drawing No. 2370.2-8145V, Revision Q) prepared by Norfolk Naval Shipyard for Code 2370, Reactor Servicing. The document provides detailed engineering specifications, assembly instructions, and fabrication requirements for a steel disposal container used in naval reactor servicing operations.
The disposal box consists of 16 component parts, including outer, middle, and inner side plates and bottom plates constructed from mild steel (2" thickness), along with padeyes, sealing gaskets, plug pads, divider plates, and fastening hardware. Key fabrication requirements mandate welding in accordance with American Welding Society D1.1 standards, with minimum weld sizes specified and snipes required to be closed during the welding process. All sharp edges and burrs must be removed with surfaces finished to 250 RMS. The interior must be primed with non-hazardous, rust-inhibitive primer, while the exterior is left as bare metal. Buna-N gaskets (DUROMETER 50-80) must be provided with cure dates and at least 85% shelf life remaining at shipment. The specification explicitly prohibits cadmium use, requiring steel fasteners to have blackened, zinc-plated, or no finish. All Buna-N components and padeyes must be shipped uninstalled, with non-lock nuts pre-installed on studs and locking nuts shipped separately. Dimensional tolerances include ±1/8" for dimensions up to 24", ±1/4" for dimensions 24" and greater, and ±1° for angles. The drawing has undergone multiple revisions through January 2018, with the most recent changes including padeye material specifications and welding symbol additions.
