The Versatile Test Reactor, a custom-designed sodium-cooled fast neutron spectrum test reactor, is one step closer to its goal of providing data to accelerate research, development, and demonstration of diverse advanced reactor designs. The Department of Energy released the Final Versatile Test Reactor Environmental Impact Statement (Final VTR EIS) on May 13, and 30 days after its anticipated May 20 publication in the Federal Register, the DOE will issue a Record of Decision on the project.

In an op-ed published online yesterday in The Hill, Ted Nordhaus and Adam Stein of the Breakthrough Institute pick apart arguments made against funding for the construction of the Versatile Test Reactor at Idaho National Laboratory. Nordhaus and Stein contend that opposition to the VTR has been led by “entrenched opponents of nuclear energy” who “fear that innovation of the sort that many U.S. nuclear startups are presently betting on might give the technology a second life.”
Digital engineering, which uses advanced technologies to capture data and optimize design in a digital environment, is being applied for the first time to a DOE nuclear project and has already realized substantial benefits.
With a new generation of nuclear reactors in the works, Idaho National Laboratory has embraced digital engineering (DE) as a means of achieving the same efficiencies that companies in the private sector have been able to realize in everything from concert halls to aircraft engines.
DE—using advanced technologies to capture data and craft design in a digitized environment—has been evolving since the 1990s. For Mortenson Construction, a worldwide construction firm, using virtual design and construction resulted in a cumulative 600 days saved over 416 projects and a 25 percent increase in productivity. By building digital twins for assets, systems, and processes, DE has avoided more than $1.05 billion in customer, production, and mechanical losses.
Leaders at INL recognized in 2018 that DE could be useful in the design and construction of new commercial and test reactors. Managing construction costs, timing, and performance will be essential to maintain U.S. competitiveness.
