NXR Activities
Message from the Director
In April 2023, JAEA established a new vision for achieving a decarbonized society, titled "A new future created with "Nuclear x Renewable," and began research and development challenges across three fields: "Synergy, Sustainable, and Ubiquitous."
To realize this new vision, the NXR Development Center was established at JAEA in April 2024 as a new organization aimed at leading technological development and implementing new technologies into society. The NXR Development Center is a flexible network-type organization that forms networks with many organizations inside and outside JAEA and aims to implement R&D results in society through open innovation.
The following special teams have been established to carry out each project in collaboration with both internal and external organizations.
(1) Special Team for RI Heat Source Development
The team aims to develop and provide an energy source that can operate semi-permanently and maintenance-free even in harsh environments.
(2) Special Team for Battery Energy Storage Development
The team aims to develop URF (Uranium Redox Flow) storage batteries that utilize non-burnable uranium. This technology would contribute to power stabilization by creating a synergy between renewable and nuclear energy.
(3) Special Team for Partitioning and Utilization Technology Development
The team aims to develop the technology for partitioning high-value elements from nuclear-spent fuel and make it widely available to society.

The NXR Development Center values challenge, speed, and teamwork. By embracing the challenge of creating a new future with many colleagues, we will contribute to necessary transformations in several areas. The transformations include creating new value through Green Transformation (GX) and Digital Transformation (DX) to achieve a decarbonized society, enhancing the quality of life (QOL) and well-being in an aging society, advancing Sustainability Transformation (SX) in the space field, and fostering next-generation regional ecosystems.
I sincerely appreciate your continued understanding and support for our new activities.
