This original diagram of the reactor tank shows the various areas of the reactor internals and tank. Workers are currently removing internals from below the core region. |

Segmentation workers use long- handled tools and video camera monitors to minimize exposure. |

These Photos were Taken with a Remote Camera

The photo to the left shows reactor internals before segmentation. |
The photo to the right shows a close up, with most of the internals removed. Workers removed the reactor core box in February. |

Immobilization
Because the beryllium reflector plates - referred to in the display panels at the start of the this page - are brittle, workers used an epoxy like compound to stabilize them.
|
The photo to the right shows the tank containing the compound. |

The photo to the left shows a worker at the controls of the tank. The compound was pumped into a steel liner containing the beryllium plates. |
