PHYSICAL PROTECTION OF ADVANCED REACTORS

Design aspects of liquid metal fast breeder reactors (LMFBR's) are discussed in terms of physical protection considerations, and important points generic to any future reactor design which impact physical protection are thereby indicated. Current thoughts on physical protection systems for future reactors are discussed, and two areas where future systems may differ most from current systems are covered. The two areas are: substantial barriers at either the perimeter or building exteriors to provide more intrinsic delay to forcible entry, and operations control elements for certain vital components to prevent unauthorized manipulation by authorized personnel.
