The third <strong>dismantlement</strong> phase involves dismantling<br />
<strong>and</strong> removing <strong>the</strong> most contaminated <strong>nuclear</strong> plant<br />
components. Neutrons escaping from <strong>the</strong> reactor have<br />
made <strong>the</strong>se components radioactive; <strong>the</strong>y can not be<br />
decontaminated. As highlighted in <strong>the</strong> diagram above,<br />
<strong>the</strong>se components include:<br />
_ <strong>the</strong> reactor pressure vessel,<br />
_ <strong>the</strong> concrete shielding that encloses <strong>the</strong> reactor<br />
pressure vessel (known as <strong>the</strong> biological shield),<br />
_ <strong>the</strong> overhead concrete slab that shields <strong>the</strong> reactor<br />
room,<br />
_ <strong>the</strong> fuel racks in <strong>the</strong> former fuel storage tank,<br />
<strong>and</strong> various fixed <strong>and</strong> moveable pressure vessel<br />
components.
