An approved DOT 7A Type A shipping container, the S100 POC (pipe overpack component) is a shielded version of the standard POC. It consists of a 6-inch diameter pipe component positioned within a 55-gallon drum by means of fiberboard/plywood dunnage, and neutron shielding materials. The overall height of the pipe component is 27.5 inches with a 6.7-inch outside diameter. The assembly of pipe component and the 55-gallon drum tare weight is about 227 kg. The pipe component body, lid and bolt flange are constructed of stainless steel. A butyl rubber or ethylene propylene O-ring is required for pipe component closure. It is also approved to transport waste to the Waste Isolation Pilot Plant (WIPP) in TRUPACT II containers for disposal.
The S100 container was designed to affect a higher packaging efficiency for neutron emitting sealed sources than could be achieved in the standard pipe component container designed and approved for use in support of the Rocky Flats closure efforts. The container utilizes high density polyethylene neutron shielding in place of the cane fiberboard which reduces external neutron dose equivalent rates per unit activity in the container. This allows container loading with a greater Curie content while maintaining compliance with external dose rate limitations for both packaging and disposal.
Neutron sources can be easily consolidated and managed in the S100. It provides convenient, safe, and retrievable nuclear material storage in a portable container that can ultimately be shipped to WIPP for disposition.
