- Description
- Provide materials, workmanship and installation, including joints and fasteners that maintain continuity of RADIATION SHIELD DOOR at all points and in all directions specified in thicknesses and locations indicated. 1. Materials, thicknesses, and configurations indicated are based on RADIATION SHIELD DOOR design prepared by Owner's radiation health physicist. This design is available to SUBCONTRACTOR on request. 2. A minimum of six (6) inches (30 cm) of Thermo Electron Corporation product Poly/Cast # 259 or equivalent encased in at least 1/2? carbon steel or stainless steel (A-36, 300 series stainless). The shield (door) shall overlap the sides of the entryway by approximately eight inches on each side and shall be as close as possible to the components mounted on the wall adjacent to the access. The door is to be located at the equipment airlock door. If hinging the door is impractical due to anchorage or space requirements, the shield(s) can be on rollers and slide on the floor across the entryway opening. The shield shall be built such that in the closed position, it is as close to the floor as practical. The shield may be opened manually, motor driven, or both. 3. The existing blast door is to remain. The shield door shall be designed and constructed so as to not interfere with the existing blast door assembly or working mechanisms. 4. Doors must be capable of being unlatched and operable by one person. The latch may be a mechanical type latch such as a surface mounted doorbolt. 5. Temperature Requirements: a. Doors must be fully operational at ambient temperatures from plus 55 degrees Fahrenheit to plus 95 degrees Fahrenheit. 6. Electrical Requirements: a. All wiring connections as required, internal and external shall be made on labeled terminal blocks. Terminal blocks shall be placed in NEMA 1 enclosures and located adjacent to the doors on the interior. All wires shall be labeled. b. SUBCONTRACTOR shall provide a mounted tongue actuated safety interlock switch as manufactured by Allen-Bradley model number MT-GD-2. The door shall be reinforced as necessary with a mounting plate to receive the interlock switch. c. Door shall be grounded. d. A power failure will not cause the door to change its lock/unlock state. 7. Hardware Requirements: Door shall have hardware to provide a fully operational and functional door regardless of whether or not it is specified or shown on the drawings. a. Door stops: Wall mounted door stops shall be provided at each door leaf, as required, to prevent the door or external accessory on the door from making contact with the adjacent walls or building accessory within the swing radius of the door leaf. The design of the unit shall allow for the replacement of the rubber bumper. Door frame stop shall be provided at head and jambs only. b. Hinges: Hinges shall be designed to resist door reactions associated with normal and seismic loads. They shall be designed to allow the door leaf to open approximately 135 degrees. c. Latch devices: Latch devices shall ensure the door remains closed. 8. Anchoring Requirements: Doors shall be supported on the existing concrete wall with anchoring devices as designed by SUBCONTRACTOR including, but not limited to base plates, anchor bolts and anchors. Reinforcing steel in the concrete walls may not be cut during installation of the anchor bolts for the door. Anchoring designs must include the provision for a 2? tolerance on anchor bolt positions in any direction. Attachment to existing blast door frames is not permitted. 9. Seismic Requirements: The door, anchors, and connections shall be designed to resist seismic loading. Horizontal and vertical seismic forces shall act simultaneously on the door and frame. Assume that excitation is applied along one of two orthogonal horizontal axes and is combined with the vertical direction. Assume doors are open during a seismic incident. For the purpose of seismic design for the doors, assume no other extraordinary forces are acting on the door at the same time. a. Design Basis Earthquake (DBE) 1) General: Door shall be designed to resist forces generated by the postulated DBE. a) Maximum Accelerations: East-West Direction = 0.41g North-South Direction = 0.40g Vertical Direction = 0.33g b) Directions are as indicated on reference drawings Paragraph 1.1.A 2) Structural Response to DBE: Limit the structural response of the door to prevent the door from falling off the hinges when in an open position. Design the door such that all stresses remain elastic. The door pins shall keep the door in place when closed. The door does not need to remain operable; it is only to stay on the hinges. 10. Interlocks: a. General: 1) Door shall be interlocked with criticality machines emergency safety shutdown system (SCRAM) to prevent execution of an experiment with the shield door open. 2) Door shall have a status light which shall be energized when the door latch is in an unlocked position. 3) Door interlock system shall not unlock the door upon loss of power. QUALITY ASSURANCE Manufacturer: 1. The manufacturer shall have experience in the design, fabrication, and installation of doors similar to those as specified in this specification. 2. The manufacturer shall have, and provide to the CONTRACTOR, an active Quality Assurance Plan which incorporates, as a minimum, the following elements of quality: a. Organization: The Quality Assurance function shall have sufficient authority, access to work areas, and organizational freedom to: identify quality problems; initiate, recommend, or provide solutions to quality problems through designated channels; verify implementation of solutions; and assure that future processing, delivery, installation, operation is controlled until proper disposition of a nonconformance, deficiency, or unsatisfactory condition has occurred. b. Quality Assurance Program: A documented Quality Assurance program shall be planned, implemented, and maintained. The program shall provide control over activities affecting quality to an extent consistent with their importance. c. Design Control: Procedures shall be established to assure the design conforms to the contact requirements. The design adequacy shall be verified by persons other than those responsible for the design. d. Control of Processes: Processes affecting quality of items or services shall be controlled. Special processes that control or verify quality, such as those used in welding, heat treating, and non destructive examination, shall be performed by qualified personnel using qualified procedures in accordance with specified requirements. e. Inspection: Inspections required to verify conformance of an item or activity to specified requirements shall be planned and executed. Inspection checklists and results shall be documented. Inspection records shall contain the following information as a minimum: 1) Item/Process being inspected 2) Applicable checklist 3) Date of inspection 4) Inspector 5) Type of observation 6) Results or acceptability 7) Reference to information on action taken in connection with nonconformances. f. Control of Nonconforming Items: Items that do not conform to specified requirements shall be controlled to prevent inadvertent installation or use. g. Corrective Action: Conditions adverse to quality shall be identified promptly, documented, and corrected as soon as practical. In the case of a significant condition adverse to quality, the cause of the condition shall be determined and corrective action taken to preclude recurrence. h. Quality Assurance Records: Records that furnish documentary evidence of quality shall be specified, prepared, and maintained. A.
