May 25, 2021 · EM crews are preparing to deactivate the former Experimental Gas-Cooled Reactor (EGCR) at the Oak Ridge National Laboratory (ORNL) before removing the contaminated facility and opening the DOE land for reuse.

Oct 27, 2020 · The Experimental Gas-Cooled Reactor is one of 16 inactive research reactor and isotope facilities that OREM is addressing and cleaning up at ORNL. This massive cleanup effort is happening concurrently with other OREM cleanup projects underway at the Y-12 National Security Complex.

A gas-cooled reactor (GCR) is a nuclear reactor that uses graphite as a neutron moderator and a gas (carbon dioxide or helium in extant designs) as coolant. [1] Although there are many other types of reactor cooled by gas, the terms GCR and to a lesser extent gas cooled reactor are particularly used to refer to this type of reactor.

This follows demolition of the Bulk Shielding Reactor in 2022 and the Low Intensity Test Reactor in 2023. In addition, crews continue deactivating a number of reactors, including the Experimental Gas-Cooled Reactor.

May 28, 2021 · Environmental mandagement (EM) crews in Oak Ridge are preparing to deactivate the former Experimental Gas-Cooled Reactor (EGCR) at the Oak Ridge National Laboratory (ORNL) before removing the contaminated facility and opening the DOE land for reuse, according to cleanup contractor UCOR.

May 27, 2021 · EM crews are preparing to deactivate the former Experimental Gas-Cooled Reactor (EGCR) at the Oak Ridge National Laboratory (ORNL) before removing the contaminated facility and opening the DOE land for reuse.

Nov 2, 2020 · On October 27, the DOE announced that the Oak Ridge Office of Environmental Management (OREM) is set to begin cleanup of the Experimental Gas-Cooled Reactor at the site. OREM and cleanup subcontractor UCOR are in the planning stages to fully deactivate the reactor for eventual demolition.

Dragon was an experimental high temperature gas-cooled reactor at Winfrith in Dorset, England, operated by the United Kingdom Atomic Energy Authority (UKAEA).

Test operations and experimental evaluations were conducted with two core loadings of different design (one consisting of dispersion plate-type fuel elements and the other of pin-type elements) and two calandriss of similar design (one fabricated …

The Experimental Technology Demonstration Reactor (ETDR) from 2008 was characterized by 50 MW thermal power, 560 ºCHe first core outlet temperature at 7 MPa, one primary loop and water cooling on the secondary side.
