## Summary

The procurement process is currently at the planning stage for a contract titled "Modelling of Critical Nuclear Facilities" with the buying organisation, United Kingdom National Nuclear Laboratory Limited. This project falls under the industry category of services, particularly focusing on technical and software programming services. The procurement involves developing 3D models to support IAEA safeguard activities related to nuclear facilities. The contract, located in Warrington, United Kingdom (region UKD61), offers a procurement value of £400,000, excluding VAT. A key milestone is the market engagement phase, inviting interested parties to contact the procurement office before 29th October 2025. The contract period is projected to start on 1st April 2026 and end by 31st March 2029, with a potential extension up to 31st March 2031.

This tender presents substantial growth opportunities for businesses specialising in advanced 3D modelling and software integration within the nuclear sector. Companies with experience in developing models that align with IAEA standards will find this opportunity suitable. Small and medium enterprises (SMEs) are encouraged to participate, given the nature of the work and the open procurement method employed. The sensitive nature of the nuclear facilities necessitates that interested contractors have the necessary security credentials to handle confidential information. Engaging in this contract could expand a business's expertise in cutting-edge modelling technologies and enhance its credibility in high-stakes and government dealings.

## Notice

Development of 3D Models for Nuclear Facilities. The International Atomic Energy Agency (IAEA) maintains its ability to verify the nuclear programmes of non-nuclear weapon State (NNWS), including the capability to rapidly respond to any significant changes required for the implementation of safeguards-related activities in the field. As one part of its longer-term preparedness activities to date, the Department of Safeguards has already been able to acquire and demonstrate a limited technical capability in using Virtual Reality (VR) navigation inside real-world 3D scans, including the ability to attach relevant geobased data sources to 2D optical imagery. Lessons learned from previous VR projects have already been applied in the development of the current capability. However, to be more effective in its ability to rapidly respond to potentially significant changes in the short term, there is a need for the Department of Safeguards to develop 3D models of a number of very specific critical facilities. As part of its long term preparedness activities, the Department of Safeguards needs to develop the ability to develop and use 3D and Virtual Reality (VR) models for training, analysis and knowledge management. This task will support the creation of models for a number of different nuclear facilities and sites, in close consultation with IAEA experts and inspectors. The 3D models will provide tangible benefits in terms of knowledge management and implementation of safeguards. This will include the training/familiarization of inspectors who may have limited experience of the specific processes at the selected critical nuclear facilities and implementation of safeguards therein. The activity within this task is highly specialised, requiring significant technical knowledge and capabilities with advanced state-of-the-art 3D modelling technology. The proposed contractor must have experience of developing 3D models and resources similar to the facilities of interest. In addition, models must have the capability of being integrated with relevant IAEA Safeguards IT architecture, standards, policies and procedures. The proposed contractor must demonstrable experience of working with the nuclear sector. The specific target for the research is considered sensitive and, therefore suppliers must meet the minimum security requirements to handle, OFFICIAL SENSITIVE information.
