Nuclear regulators are updating physical security rules to accommodate small modular reactors. The new framework allows developers to reduce or eliminate onsite armed response forces by relying more heavily on engineered safety features, early detection systems, and offsite law enforcement support.

Traditional security staffing models designed for large gigawatt plants create unsustainable operating costs for smaller facilities. Integrating security into the initial engineering phase requires precise tracking of detection and delay timelines. This approach alters compliance burdens for developers while reducing long term operational expenses across the sector.

New rules and smaller modular plants are reshaping nuclear security, with protection built around design, detection and lifecycle planning.

The pipeline of small and advanced reactors has grown quickly with more than 120 Small Modular Reactor (SMR) designs globally and at least seven designs already operating or under construction. Many of these units will not look like the plants that shaped today's security rules. They will be smaller, built in modules over several years and sited next to factories, data centres or remote communities rather than on large dedicated estates. Many will rely on passive safety and run with a handful...
