What design and safety features are in place to prevent and/or detect any leakage from the reactor cooling or spent fuel storage pools?

The NuScale/UAMPS materials describe the spent fuel storage and reactor pools as stainless steel lined concrete pools. The design of these pools includes a reactor and spent fuel leakage detection system to provide for collection of any water leaking from a weld in a pool liner and allows detection of the leakage to facilitate appropriate corrective actions. The leakage detection system consists of a series of drain channels between the pool liner and concrete base mat and pool walls of the reactor building. This system allows for the early detection, localization, and correction of leaks in the pool liner. Leaks can be repaired via a variety of industry standard methods depending on the location and nature of the leak.
