The Submersible Canister (SubCan) facility is an irradiator housed at the bottom of the thirty-one foot open reactor pool and consists of the following three components:

• 31 pencils of high activity Cobalt-60 (Co-60).
• An aluminum table unit
• A modified aluminum submersible chamber

The Co-60 pencils are fixed in a circular geometry on the top of the table unit. The submersible chamber is lowered into the geometric center and positioned by use of an aluminum cone bolted at the bottom of the submersible chamber. This cone was designed to mate with a 2 and 3/8-inch diameter hole on the tabletop thereby ensuring reproducibility of chamber position. The submersible chamber cover has been modified to accept a central Co-60 source. The central source is lowered into the modified chamber cover after the chamber is on the tabletop. This center source results in increased dose uniformity within the chamber.

Dose Rate:

• 1.5 Megarad/hour (15 kiloGray/hour) with Center Cobalt Source
• 1.0 Megarad/hour (10 kiloGray/hour) without Center Cobalt Source

Sample Size:

• Up to 8-inch vertical by 9-inch radial

Uses:

• Medical product sterilization
• Material Evaluation
• Hardness testing and characterization of electronics
