CLEVELAND, Ohio-- FirstEnergy Corp. said Monday it has purchased a replacement lid for the Davis-Besse reactor near Toledo and wants to install it in 2011. Davis-Besse has been shut down since Feb ...

The shield plug consists of three lids placed on top of each other to block extremely high radiation emanating from the reactor core. Each lid weighs 150 tons.

Crews will replace 256 of the 764 nuclear fuel assemblies in the reactor core with new fuel. The biannual fuel outages allow all fuel to be replaced on a rotating schedule every six years.

The photos were the first from inside the main structural support called the pedestal in the hardest-hit No. 1 reactor's primary containment vessel, an area directly under the reactor's core.

First reactor core block for non-nuclear testing. The newly assembled reactor core hardware comprises a carefully engineered 1:2 scale block designed to mimic a ZEUS fuel element.

Because of the intensity of radiation, a human could spend only 90 seconds in the damaged core, even while wearing protective gear. First, they constructed an exact duplicate of the reactor nearby.

NANO Nuclear Energy Inc has assembled the first reactor core hardware of its ZEUS solid core battery reactor for initial non-nuclear testing. The fuel element being prepared for testing (Image: NANO ...

The plant’s control panel and a model of the reactor core will be preserved, as well as signs, maps, and photos from the time of TMI-2’s partial meltdown in 1979. By; Rachel McDevitt, StateImpact ...

It was also the first reactor ever to run on uranium-233 or U-233. Though it ran at full power for more than 13,000 hours from 1965 through 1969, the Department of Energy eventually lost interest ...

The breakthrough marks the first time that the core of a fusion reactor has given out more energy than it has taken in, but significant obstacles still need to be overcome.
