LLCReactor Segmentation

• The major components of the reactors are:– The reactor vessel (RV); and

Th t i t l (RVI)– The reactor internals (RVI)• RV and RVI now require remote cutting because of the levels of radioactivity

• All segmentation performed in reactor cavity– Internals under water– Vessel dry (after cavity draining)– All cuts performed mechanically (currently)
