Nuclear power is experiencing a remarkable resurgence globally. This is driven by urgent climate goals, energy security concerns, and technological innovation. In this context, industry specialists convened at Marsh’s recent Nuclear Insurance Symposium in London to examine the changing risk environment. This is a summary of the session focused on the complex legal frameworks governing nuclear liability.

Designing and building these ground-breaking nuclear facilities made the site the birthplace of the country’s civil nuclear industry. But today, its people and supply chain partners have a different challenge – how do we safely decommission these legacy facilities? And how can we do it in such a way that others can learn and benefit from our work?

The April 1986 accident at the Chernobyl nuclear power plant remains a defining moment in the history of nuclear energy. The lessons of this tragedy are interwoven with a recurrent theme: namely, the importance of international cooperation. The major impacts of Chernobyl fall into three categories: the physical impacts, in terms of health and environmental effects; the psychological and social impacts on the affected populations; and the influence of the accident on the nuclear industry worldwide.

Recent developments in artificial intelligence have underlined how quickly the cyber risk landscape is evolving. The recent controlled release of Anthropic’s Mythos model, reportedly capable of autonomously identifying and exploiting previously unknown software vulnerabilities, prompted urgent discussions among regulators, banks and government agencies in both the US and UK.
