Details

The nuclear Regulated Asset Base (RAB) model is a method of funding future nuclear projects, providing support for their design, construction, commissioning, and operation.

In order to bring a nuclear project to the point of entering construction, the company must invest significantly in the project’s development. This could include, for example:

  • building the project company
  • maturing the supply chain
  • investigating the land

If, following this investment, a project is taken forward under the nuclear RAB model, appropriately incurred development costs can be added to the RAB. This guidance sets out the criteria and process for doing so.
