Background:
The Y-12 National Security Complex is located in Oak Ridge, Tennessee. It is a Department of Energy (DOE) National Nuclear Security Administration (NNSA) national security complex managed and operated by CNS.
General Scope Description for 9204-02E GB02 Airlock/Hood:
The Airlock (glovebox) System project includes a manufacturability review of current design, fabrication, and testing of the system and the associated equipment necessary to maintain the airlock/glovebox at the desired operating conditions. The Airlock/glovebox) will be fabricated to the design drawings.
The Airlock (Glovebox) System includes the following:
• Airlock (Glovebox)
• Hood
• Rail
• Vertical Sliding Doors
Airlock/Glovebox
The airlock will require three vertical sides and one angled side. The dimensions are approximately 135” tall, 76” long by 57” wide at the base with a top width of 33”. A cart (with rails) will pass through the airlock from the hood to the glovebox and back. The vertical side will have five (5) glove ports while the slanted side will have six (6) glove ports. Process glove ports should be placed at a distance of 48 in. ± 4 in. from the operation floor to the centerline of the glove port. A mechanical hoist will be mounted to the inside top of the airlock to help move/clean material. There will be lights, meters and exhaust mounted to the top of the airlock. Both glove port sides shall be constructed out of glass which meets all standard glove box requirements. Provisions are to be made to include a drain system.
Hood
• The dimensions of the hood are approximately 122” tall, 44” deep by 60” wide. There will be lights, meters and exhaust mounted to the top of the hood. A slot will be required for the hoist cables to transport the material into the hood area and place on the cart.
Rail
• The hoist rail is approximately 90” long. The hoist will include an electrical motor. The rail will attach to an existing mezzanine structure on one end and a vertical column on the other end.
Vertical Sliding Doors
• There will be a vertical sliding door (VSD) at each end of the airlock. One end connecting to the glove box while the other is connected to the hood. The actuation of the VDS will be by electrical/mechanical lifts.
The unit will operate with positive pressure with a minimum of 0.3”-0.8” of WC. The airlock/glovebox will be constructed to support a negative pressure in the event of a hole in the glove or glove port opening. Purging the system will be by Argon.
Items included in the scope include the Airlock/Glovebox shell, windows, glove ports, gloves, pumps, piping, valving, PLC controls and software, Human Machine Interface (HMI) stations, atmospheric monitoring, exhaust filtration, etc. Verification of the Airlock/Glovebox performance will be demonstrated in a Factory Acceptance Test (FAT) at the Supplier’s location prior to shipment.
