The Draining and Refilling System (DRS) provides a means for draining the Primary Heat Transfer Systems (PHTSs), Tokamak Cooling Water System (TCWS) piping and in-vessel components such that maintenance and inspection can be performed and systems can be refilled after maintenance or inspection operations are completed. The DRS piping system is designed to provide primary confinement of TCWS fluids including Activated Corrosion Products and tritium entrained in the cooling water and maintains leak tight integrity during all operating modes. Within the DRS, the Vent Collection System (VCS) Vacuum Pump includes the motor, vacuum pump, temperature switches, exhaust muffler, vibration isolators, and other pump assembly components, interconnection piping, valves, and the instrumentation needed to achieve 4 kPa pressure (vacuum) in the Safety Drain Tanks (SDTs) with full operating flow rate of 100 acmh.
