ACTI

Advanced Construction Technology Initiative

Making Nuclear Construction Faster and More Affordable

From the beginning of the era of nuclear power plants, construction of new facilities has been hampered by cost overruns and schedule slippages. The National Reactor Innovation Center’s (NRIC’s) Advanced Construction Technology Initiative (ACTI) was created to oversee these and other issues by facilitating the development of advanced nuclear energy facility construction technologies and approaches through partnerships that could provide game-changing benefits.

The work of ACTI is funded and managed through NRIC, which was established in 2019 to enable advanced reactor demonstration and deployment. Advanced construction techniques for the facilities that house these modern reactors is a critical step toward deploying this new technology.

The initial project will be conducted in two phases: first, the initial phase will focus on technology development and preparation for a small-scale demonstration. Second, pending the successful completion of phase one, and with future appropriated funds being available, the next phase is planned for carrying out the demonstration of this new technology within tree years of the award being granted.

Three Ways to Demonstrate Advanced Nuclear Construction Technologies for 2025 and Beyond

The first project under this initiative will demonstrate multiple technologies used successfully in other industries which have not been tested within the context of nuclear energy. These include:

  • Vertical shaft construction, a best practice from the tunneling industry that could reduce construction schedules by a year or more

  • Modular, steel/concrete composite walling systems significantly reduce the labor required on construction sites

  • Advanced monitoring, coupled with digital twin technology, can create a digital replica of the nuclear power plant structure
