Description

Decommissioning nuclear facilities is a relatively new field, which has developed rapidly in the last ten years. It involves materials that may be highly radioactive and therefore require sophisticated methods of containment and remote handling. The wastes arising from decommissioning are hazardous and have to be stored or disposed of safely in order to protect the environment and future generations. Nuclear decommissioning work must be carried out to the highest possible standards to protect workers, the general public and the environment. This book describes the techniques used for dismantling redundant nuclear facilities, the safe storage of radioactive wastes and the restoration of nuclear licensed sites.

Key Features

  • Describes the techniques used for dismantling nuclear facilities, safe storage of radioactive wastes, and the restoration of nuclear licensed facilities.
  • Provides the reader with decommissioning experience accumulated over 15 years by UKAEA.
  • Contains valuable information to personnel new to decommissioning and waste management.

Readership

Industry: environmental engineers, generally and nuclear clean-up engineers and managers, specifically

Additional interested areas: Academic: as a supplementary text for graduate students in nuclear engineering. Course titles could include: Nuclear Radioactive Waste Management and Decommissioning Physics and Technology of Nuclear Reactors
