Sample interview questions: Can you explain the process of pipefitting for nuclear or radioactive material transport systems?
Sample answer:
Pipefitting for Nuclear or Radioactive Material Transport Systems
Process Overview:
- Design Development: Consult with engineers to determine the system specifications, material compatibility, and safety requirements.
- Material Selection: Choose materials that meet strict safety standards, such as stainless steel, bronze, or Monel.
- Fabrication: Cut, bend, weld, and assemble pipes and fittings according to blueprints and specifications.
- Welding: Use specialized welding techniques, such as TIG (tungsten inert gas) or orbital welding, to ensure strong and leak-proof welds.
- Inspection and Testing: Conduct rigorous inspections to verify weld quality, pressure hold, and overall system integrity. Tests include hydrostatic, helium leak, and radiographic testing.
- Installation: Position and secure piping systems in designated areas. Follow stringent safety protocols to prevent contamination.
- Commissioning: Start up and optimize the system, ensuring proper flow rates, pressure, and temperature.
- Maintenance and Monitoring: Regularly inspect and maintain the system to ensure safety and reliability. Perform leak tests, calibrate instruments, and address any repa… Read full answer
