Abstract	When the Canadian Nuclear Safety Commission (CNSC) became aware of concerns relating to the collection of debris at suction strainers for emergency core cooling (ECC) systems following the incident in Barsebäck, Sweden, it issued a notice to Canadian utilities requiring them to review their ECC strainer capability in view of the potential increase in pressure drop, and address any deficiencies. During this review period, a number of uncertainties were identified as needing resolution, principally those items directly related to the head loss across the strainer (both in the short and long term), as well as a few secondary issues such as the likelihood of air ingestion. Canadian utilities contracted Atomic Energy of Canada Limited (AECL), through the CANDU owners group (COG), to perform extensive fundamental testing to establish the important parameters governing ECC strainer performance. AECL expanded upon this knowledge base with additional tests to confirm proposed designs for specific applications. As a result of all the testing, a substantial body of ...
