The International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) was established in 2000 to ensure that nuclear energy is available to contribute, in a sustainable manner, to the growing energy needs of the current century and beyond.

The 34th INPRO Steering Committee Meeting in 2025 endorsed the initiation of an INPRO collaborative project (CP) on national and international deployment models for transportable nuclear power plants (TNPPs). This CP aims to cover a comprehensive set of deployment models for floating and land-based TNPPs using results from past INPRO studies. The deployment models for floating NPPs and transportation of land-based TNPPs by sea are expected to be complimentary to future ATLAS activities. These deployment models could include national deployments and export scenarios to experienced and embarking countries using fuelled or unfuelled TNPPs. An important objective is to identify deployment models that can be covered by existing national and international legal instruments. In addition, pilot deployments that could provide input to facilitate the revision of existing legal instruments will also be studied.
