The US Department of Energy’s (DOE’s) Office of Nuclear Energy said on 29 July that the Oak Ridge National Laboratory (ORNL) and Analysis and Measurement Services Corporation (AMS) had recently completed testing of sensors for small light-water reactor systems. The performance data will be shared with US nuclear companies to improve sensor instrumentation for advanced light-water small modular reactors (SMRs). The data could also be leveraged to support other advanced reactor types cooled by gas, liquid metal or molten salt.

The US Department of Energy said performance data will be shared with US nuclear companies to improve sensor instrumentation for advanced light-water small modular reactors.

The data could also be used to support other advanced reactor types cooled by gas, liquid metal or molten salt. ORNL tested the nuclear-grade resistance temperature detectors using a thermosyphon test loop and a specialised steam loop constructed specifically for the project.

The US National Aeronautics and Space Administration (NASA) said on 13 July it was leading an effort, working with the Department of Energy (DOE), to advance space nuclear technologies. The government team has selected three reactor design concept proposals for a nuclear thermal propulsion system. The reactor is a critical component of a nuclear thermal engine, which would utilise high-assay low-enriched uranium (HALEU) fuel.

Plants could be used for missions to Mars A NASA illustration of a conceptual spacecraft using nuclear thermal propulsion. Courtesy NASA. NASA has selected three teams of companies to perform concept studies of nuclear thermal propulsion (NTP) reactors while making plans to fund similar studies for nuclear surface power systems.

Each contract is worth approximately $5m and will last one year.

One contract will go to BWX Technologies, working with Lockheed Martin. A second contract will go to General Atomics Electromagnetic Systems, working with X-energy and Aerojet Rocketdyne. The third will go to Ultra Safe Nuclear Technologies, working with its parent company, Ultra Safe Nuclear Corporation, as well as Blue Origin, General Electric Hitachi Nuclear Energy, General Electric Research, Framatome and Materion.

All three studies are focused on developing a design for a reactor that would be part of a future NTP system. That reactor would heat up a propellant such as liquid hydrogen, generating thrust at far higher efficiencies than conventional propulsion systems and enabling shorter transit times for missions to Mars.

A common misconception about advanced nuclear technologies is that they are largely conceptual and will not be commercialised in time to contribute to meeting near-term climate goals, but a comprehensive look at global efforts to develop advanced nuclear reveals rapid progress towards commercialisation and operation, write Clean Air Task Force, ClearPath, Nuclear Innovation Alliance, Pillsbury and Third Way.

The US Trade and Development Agency (USTDA) on 30 June announced grant funding to Poland’s Polskie Elektrownie Jadrowe (PEJ – Polish Nuclear Power Plants Ltd) for a front-end engineering and design study that will help develop Poland’s first two nuclear power plants, facilitate a transition away from coal-fired power, and strengthen efforts to ensure its long-term energy security.

The US Trade and Development Agency (USTDA) will release grant funding for Poland’s Polskie Elektrownie Jądrowe (PEJ, formerly PGE EJ1), the company charged with managing the country fist nuclear power project, for a front-end engineering and design study involving US-based Westinghouse Electric Company and Bechtel Corporation.

USTDA said in a statement that the study will be carried out by Westinghouse and Bechtel and will aim to support the Polish government’s decision-making process for the deployment of two nuclear power stations, each consisting of three nuclear reactors.

According to the statement, the study will provide PEJ with layout plans for the location of the first nuclear power station, a strategic licensing plan, a project schedule, and a budgetary cost estimate for delivery, construction and start-up of the first power plant.

US-based Curtiss-Wright Corporation on 24 June announced that it has been selected to participate in Project SAFARI, a US Department of Energy DOE) project to develop Digital Twin technology for advanced nuclear reactors. Project SAFARI is one of nine initiatives under the Generating Electricity Managed by Intelligent Nuclear Assets (GEMINA)programme sponsored by the Advanced Research Projects Agency-Energy (ARPA-E). ARPA-E GEMINA projects aim to transform operations and maintenance systems in the next generation of nuclear plants through the development of specialised Digital Twin technology.
