About this file
This is a technical drawing (D-60-022) showing the CO2 gas system diagram for the National Bureau of Standards Reactor (NBSR) at the National Institute of Standards and Technology's Reactor Radiation Division in Gaithersburg, Maryland. The drawing was originally created in 1968 and has undergone multiple revisions, with the latest revision occurring in July 2023.
The diagram details a complex CO2 gas system that includes a 4,043-gallon reactor vessel, an 800-gallon reserve tank, and various components such as controlled valves, pressure relief valves, pressure regulators, check valves, ball valves, diaphragm valves, gate valves, rotameters, and pressure gauges. The system features multiple flow paths, including connections to a Flexo Rabbit System (B-200), thermal shield, and irradiated air lines. Key pressure settings are specified, including 25 psig, 30 psig, and water column measurements of 5" and 8-9". The drawing includes detailed pipe sizing information and an embedded CO2 circular header with six nozzles.
