More than 1,100 people gathered in London for the 50th World Nuclear Symposium, taking part in a packed programme of discussions, panels and networking. In addition to the usual broad range of topics there were also two special full day programmes - one focused on end energy users and one on finance.

The event also saw the publication of 2025's World Nuclear Fuel Report, which warned that gaps could be opening up in the supply-demand picture over the coming years and investment decisions need to be taken now to fuel the forecast increase in nuclear power capacity.

The World Nuclear News team were there and have put together a series of reports on the symposium's proceedings, and the fuel report's findings.

• Cecile Gregoire-David, Head of Uranium, Conversion and Enrichment Services, EDF

Nuclear reactors worldwide generated 2667 TWh of electricity in 2024, beating the previous record high of 2660 TWh which was set back in 2006, according to World Nuclear Performance Report 2025.

In this edition Jonathan Cobb, author of the report, outlines the key findings of the latest edition of the annual World Nuclear Association publication, which include the dominance of Asia in terms of new reactor capacity over the past decade.

There is also clear evidence that reactor performance does not decline with age - the reverse can be true with modernisation, uprates and long-term operation programmes helping capacity factors reach an average of 83% across the global fleet (the capacity factor is a percentage of what the output would have been if a reactor had operated at full capacity for every moment of a year).

Jonathan, who is senior programme lead, climate, at World Nuclear Association, also considers how likely it is that the record is going to be broken again in the next few years.

Andy White, senior vice president of Energy and Environment International for Amentum, talks about his background and the work Amentum is doing in the UK and across Europe in the nuclear sector.

Among the topics covered:

* The change of attitudes which means that the future decommissioning process is included in the planning stages for new nuclear (and how that should reduce the number of 'surprises' when decommissioning plants)

* The company's work on new nuclear in the UK at Hinkley Point C and Sizewell C and SMRs and operations in Poland, France, the Czech Republic as well as Norway and the Netherlands

* The benefits of bringing in technology, skills and people from other sectors (and countries) to help with what looks like being a forthcoming rapid expansion of new nuclear.

* Plus Amentum's nuclear fusion work, including at ITER, and the general outlook for nuclear, and how financing and regulation can help industry meet the demand for new capacity

We also bring you Claire Maden's conversation with Nima Ashkeboussi, vice president government relations and communications at Global Laser Enrichment, earlier this year at the World Nuclear Fuel Cycle conference in Canada.

In it he talks about the company's laser enrichment technology, explaining how it works and the big plans the company has - including 30-years' worth of work relating to the US Department of Energy's 200,000+ tonnes of depleted uranium. GLE's plan is to re-enrich this, so cleaning up a stranded asset and in the process providing a new source of fresh fuel.

GLE began a large-scale enrichment demonstration programme in May, and the US Nuclear Regulatory Commission accepted for review the company's licensing application for a new facility to be built at Paducah, Kentucky earlier this month.
