Scope

This document specifies the requirements for the design and performance evaluation of the strainer, since the performance of the strainer is important for the above-mentioned nuclear safety.

This document is applicable to the design and performance evaluation of the ECCS strainer in PWR NPPs, particularly those with primary design philosophies that rely on ECCS pumps. Although tailored to PWR NPPs, it can also serve as a valuable reference for other reactor types, providing insight into the design and effectiveness of filtration systems in various nuclear power applications.
