The UK has engaged in peaceful nuclear cooperation and supported developing countries in the uses, safety and security of nuclear technology for medicine, agriculture and power. This has been channelled through the IAEA’s Technical Cooperation (TC) programme or bilateral aid.
The UK reported that it has paid its Regular Budget and Technical Cooperation Fund contributions to the IAEA in full and on-time and made significant extra-budgetary contributions to support the refurbishment of the Seibersdorf laboratories, and in support of the IAEA's nuclear safety and security programmes which underpin the peaceful uses of nuclear technology. The UK reported in 2018 that it made a £4.1M contribution to the IAEA Nuclear Security Fund.
The UK reported that it plays an active role in multilateral organisations to promote the peaceful uses of nuclear technologies, including through the International Framework for Nuclear Energy (IFNEC), the Nuclear Innovation: Clean Energy Future initiative, the Nuclear Energy Association, and the IAEA. The UK’s national report to the 2022 NPT Review Conference set out in more detail the projects it has funded through the IAEA’s Technical Cooperation Fund (TCF) on Sterile Insect Technique, Renovation of the Nuclear Applications Laboratories (ReNuAL), Covid-19 response, Marine plastics, and the Marie Skłodowska Curie Fellowship Programme (MSCFP).
The UK states that it has continued to support the IAEA's Peaceful Uses Initiative (PUI) launched in 2010 through its contributions to the Technical Cooperation Fund (TCF), to which it has contributed more than £20 million and more than £6 million in extra-budgetary contributions since 2020. This includes work on marine plastic pollution, isotope hydrology and environmental protection.
