Abstract

A proposed modification to the OPG Pickering Nuclear  Generation Station Emergency  Water Supply (EWS) system was  analyzed using the Industry Standard Toolset code GOTHIC [1] to determine the acceptability of the proposed system configuration during  pump start-up. The new configuration of the system included a vertical dead-ended pipe, initially filled with air. The simulation demonstrated that no significant water hammer effects were predicted and tests performed with the new configuration confirmed the analysis results.
