Large Scale Machining Of Steel Doors For A Nuclear Waste Containment Application

Steel Doors for Nuclear Waste Containment Application
Steel Doors for Nuclear Waste Containment Application

The project highlighted here represents a large scale machining effort for Niagara Precision. These doors were designed for use on the front of an X-ray radiation containment structure, and were ultimately installed at a nuclear power facility in Ontario, Canada. From the customer’s specifications, we developed a design and conducted feasibility studies to ensure that the finished product would perform exactly as expected. Composed entirely of structural steel, the design also included a low speed drive mechanism to operate the two 19,000 lb. doors. Each door had a final dimension of 10’ in width, 20’ in length, and 3” thick, which had to be manufactured to tolerances of ±.005”. The machining, all of which was complete in-house, consisted of CNC turning and milling, as well as the use of our boring mill. After extensive dimension and visual inspections the doors were painted, assembled, and put through vigorous functionality testing. This project was designed, manufactured and delivered in 5 months.
