Cooling Systems

The cooling system of a nuclear power station is a safety critical system. For more than 10 years companies such as Electricite de France and Edison have used Flowmaster to design and optimise power station cooling systems.

Typical simulations include:

  • Surge (Waterhammer) Analysis
  • Valve closure rate determination to prevent reverse flow and maintain condenser pressure
  • Pump sizing and selection

For a range of scenarios such as:

  • Single pump trip (shutdown)
  • Power blackout – all pumps tripped
  • Pump change over (one trips one starts)
  • Cross-over valves open or closed.

Case Studies

Commonwealth Edison avoid considerable expense of a major plant rework
Commonwealth Edison's engineers using Flowmaster were able to show that the initial assumption about the cause of the transients was actually incorrect. Therefore, the proposed changes were inappropriate and Commonwealth Edison was then able to avoid the considerable expense of a major plant rework.

Queensland drought affects power station - Flowmaster helps to engineer a solution!
Flowmaster was used to carry out a complete hydraulic analysis in order to validate it. Flowmaster simulations included a range of operating scenarios from the normal operating modes to extreme power failure conditions. Pressure envelopes, surge tower draw down, pump operation and air valve activities calculated during the Flowmaster simulations were used to further optimise the pipeline design to enhance safe and economical operation.
