The design of a pressure vessel and testing procedures for the determination of the effect of high temperature pressurised helim on valve contact welding / Hein Schmidt
The PBMR (Pebble Bed Modular Reactor) is one of the current developments in the field of nuclear power generators. The control philosophy of the PBMR system relies heavily on the controlling of valves. The current control valves are subjected to a maximum temperature of 350°C with a pressure differe...
