Has anybody here worked on 1700psi pressurized heat transport equipment containing 250C contaminated and tritiated coolant? Personal airlocks are another. Ever figure the tons force on the walls and doors with just 1/2 atmosphere of pressure?
All the inspections we do are on Nuclear reactors, and piping components. However we use pressurized water to test the system prior to going online.
The water removes much of the volatility when compared to air, but none the less, when the unit is online the systems carry radioactive steam up to 1800 PSI on a PWR vessel, and various chemicals used in the industry.
Air is much more volatile under pressure than water.
I must state we also use additional methods of inspection to check the full volume of the welds and/or repairs to ensure their integrity.
