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. Diagram of Reactor Tank Segmentation workers use long- handled tools and video camera monitors to minimize exposure.

These Photos were Taken with a Remote Camera

Photo of reactor internals before segmentation 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. Photo of close up, with internals removed.

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. Tank containing the compound image Worker at the controls of the tank image 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.
