The VTR is “crucial” for U.S. national security, Atlantic Council leaders contend

An article written by national security experts Thomas Graham Jr. and Richard W. Mies, published online in The National Interest on August 3, argues that a recent move by the House Appropriations Committee to zero out the budget for the Versatile Test Reactor “has grave ramifications for U.S. national security and the fight against climate change.” Funding and building the VTR would present an opportunity for the United States to regain its leadership role in nuclear reactor designs and fuel, Graham and Mies assert.

Former ambassador Graham is chairman of the board of Lightbridge Corporation and former general counsel and acting director of the U.S. Arms Control and Disarmament Agency. Retired admiral Mies served as the fourth commander in chief of U.S. Strategic Command. Graham and Mies serve as cochairs of the Atlantic Council’s Nuclear Energy and National Security Coalition.

DOE’s Huff: VTR is key to sustained advanced reactor innovation

Kathryn Huff, the Department of Energy’s acting assistant secretary for nuclear energy, asserted in an article published online by the Office of Nuclear Energy (DOE-NE) on July 30 that demonstration reactors, such as the Natrium and Xe-100 reactors being built as full-size power producers with cost-shared funding from the DOE, and test reactors, such as the Versatile Test Reactor, are both necessary for nuclear innovation. Both are also line items in the DOE budget request, and Huff’s article sends a clear message to appropriators about the need to fund both the Advanced Reactor Demonstration Program (ARDP) and the VTR.

“Now is the time” for more ATR capacity: A conversation with Lightbridge

Operators at the Advanced Test Reactor at Idaho National Laboratory have begun a nine-month outage to perform a core internals changeout. When the ATR is restarted in early 2022, the top head closure plate of the pressurized water test reactor will have new access points that could permit the irradiation of more fuel and material samples in the reactor’s high-flux neutron conditions.

Nine-month outage preps ATR for years of continued operation

The Advanced Test Reactor (ATR) at Idaho National Laboratory is getting an overhaul that will keep it off line for nine months. When the ATR is restarted in early 2022, the one-of-a-kind pressurized water test reactor—which is operated at low pressures and temperatures as a neutron source—will be ready for another decade or more of service, with the potential for more experimental capacity in years to come.

ATRC Upgrade

At first glance, the Advanced Test Reactor Critical (ATRC) Facility has very little in common with a full-size 800- or 1,000-MW nuclear power reactor. The similarities are there, however, as are the lessons to be learned from efforts to modernize the instrumentation and control systems that make them valuable assets, far beyond what their designers had envisioned.

One of four research and test reactors at Idaho National Laboratory, the ATRC is a low-power critical facility that directly supports the operations of INL’s 250-MW Advanced Test Reactor (ATR). Located in the same building, the ATR and the ATRC share the canal used for storing fuel and experiment assemblies between operating cycles.
