CONVENTIONAL    CONSTRUCTION

 

 

 

The conventional facilities for the NASA Space Radiation Laboratory will provide approximately 400 sq. ft. of new shielded experimental space, a 4,200 sq. ft. laboratory support facility and a 2,800 sq. ft. Building for power supplies. The new facility will require rerouting the existing road. 

It is proposed to extract the beam from the Booster tunnel through a new 12 inch diameter steel pipe exiting in a northerly direction. The beam will be transported to the new experimental area through an 11 foot diameter corrugated metal tunnel approximately 250 feet long. A concrete and corrugated metal tunnel service  structure will be provided which will also serve as an emergency exit meeting the life safety code. The tunnels will be shielded with 15 ft. of earth cover equivalent.

The experimental area will be a reinforced concrete building with  20 ft. x 20 ft x 10 ft. high interior space.  The concrete walls, roof and floor will be four ft. thick with 11 ft. of earth atop the facility for radiation shielding. Equipment and personnel access is provided through a labyrinth from the laboratory support building. A concrete beam stop will be constructed at the downstream end of the experimental area.

The laboratory support building will be a 42 ft. x 100 ft. non-combustible pre-engineered steel frame on concrete footings and foundations with concrete slab on grade and a standing seam metal roof.  Exterior walls will be insulated metal panel wall construction.  Walls and roof will meet or surpass energy conservation standards with sash of insulated double glazing in thermal break aluminum framework. Space will be provided for two medical laboratories, two biology laboratories, including temporary animal holding and preparation areas, a wash booth, two control rooms, a radioactive storage area and a mechanical equipment room.  Building access and security will be via "card" entry system and video monitoring to BNL Security???.  Parking will be provided for 20 workers.

Power supplies for the beam transport magnets and various other equipment will be  located in a separate 2,800 sq. ft. building adjacent to the transport tunnel.

       The facility environments will be controlled by an efficient HVAC system designed to optimize energy conservation. Air conditioning will be provided for laboratories and control rooms in the support building and for the power supply building. The facility will be tied into the existing sitewide Energy Management and Control System.  The fire protection system will be hydraulically designed, in accordance with NFPA 13.  Lighting levels and equipment will be designed to meet the latest DOE energy conservation requirements and to assure low maintenance costs. Laboratory environments will be monitored and recorded with appropriate alarms.

Sitework will include modifications to the existing Booster, concrete walls to retain earth shielding, relocation of existing roadway, and parking.  Trenching, excavation, backfilling as well as relocation, extensions, and connections to existing power, water, sanitary and storm sewers, alarm and telephone and computer networks will all be included.
