nditions. Steel liners covering floors and lower portions of walls should be considered in rooms and cubicles where significant volumes of liquid and wet wastes are stored to ensure containment in the event of a major container failure or leak. 3. The following design objectives and criteria apply to wet radioactive waste storage facilities: A. Structures that house liquid radwaste storage tanks should be designed to seismic criteria as defined in this SRP section and SRP Sections 11.2, 11.3 and 12.3-12.4, and guidance of RG 1.143 for wastes produced during normal operation and AOOs. Foundations and walls shall also be designed and fabricated to contain the liquid inventory that might be released during a container/tank failure and include provisions to pump liquids to appropriate systems for storage or processing. The design should be reviewed and evaluated against the requirements of 10 CFR 20.1406 and guidance of RG 4.21, and applicable industry standards. B. All tanks or containers should be designed to withstand the corrosive nature of the types of wet wastes being stored. The design shall also consider the duration of storage under which the corrosive conditions exist. C. All storage structures should have curbs or elevated thresholds with floor drains and sumps to safely collect wet waste in the event of the failure of all tanks or containers. Steel liners, covering floors and lower portions of walls, should be considered in rooms and cubicles where significant volumes of liquid and wet wastes are stored to ensure containment in the event of a major container failure or leak. There should be provisions to remove or pump spilled wet waste to the radwaste treatment systems. D. All tanks and containers shall have provisions to monitor liquid levels and to sound an alarm (local and control room) in the event of potential overflow conditions. 11.4-55 Revision 4 – January 2016 E. All potential releases and release pathways of radioactivity (e.g., evolved gases,
