Radium designed a lightweight compact cart that stores the inserts when they are removed from the primary manway. Each cart is designed to hold 2 inserts in their designated (hot or cold leg) slots on the cart. The inserts are supported on polyethylene rollers that allow rotation of the inserts for cleaning and inspection processes. The insert do not come into contact with metal. The rollers fully support the inserts even with the lid installed.
The compact cart is designed to streamline the cleaning, inspection, and storage of the inserts on the primary platform. This is a safer way to accomplish these tasks and can be done using the ALARA principles to ensure dose is minimized.
