This document summarizes the types and volumes of radioactive waste in the UK and provides information on geological disposal facilities (GDFs) for long-term storage. It discusses that GDFs would involve immobilizing radioactive waste within deep underground facilities located more than 1000 meters below the surface for permanent storage. The document also categorizes radioactive waste as high, intermediate, low, and very low level waste and provides current and predicted volumes of each type. It describes the characteristics and current methods of storage and disposal for each category of waste.
