Chapter 2: Introduction to Nuclear Safety
Features to enable the safe use of non-permanent equipment for accident management
Non-permanent equipment is defined in SSR-2/1 (Rev. 1) as “equipment which needs not necessarily be stored on the site” (footnote 22 para 6.28B).
Requirements 58 (Control of containment conditions), 68 (Design for withstanding the loss of off-site power) and 80 (Fuel handling and storage systems) require the design to include features to enable the safe use of non-permanent equipment for restoring the capability to remove heat from the containment, to restore the necessary electrical power supply and to ensure sufficient water inventory for the long term cooling of spent fuel and for providing shielding against radiation.
