    The discussions on decommissioning funds have focused on nuclear power plants. Decommissioning of other facilities must not be overlooked, in particular for high cost facilities, such as reprocessing plants (the estimated cost of decommissioning the Sel-lafield plant in the UK is € 58 billion) or facilities having experienced incidents or acci-. •The design of the nuclear power plant should ensure that authorized dose limits and dose constraints for site personnel and the public will not be exceeded over specified periods (e.g. monthly, quarterly or annually) in operational states (normal operation and anticipated operational occurrences) and also in decommissioning.

Methods for reducing occupational exposures during the decommissioning of nuclear facilities: report of a Technical Committee Meeting on the Methods for Reducing Occupational Exposures during the Decommissioning of Nuclear Facilities organized by the International Atomic Energy Agency and held in Prague, October 3.

Radiological and non-radiological hazards of decommissioning activities of nuclear facilities Radiological hazards. Radiological hazards fall into categories: exposure, criticality, and breach (loss) of containment.

Overall radiological risks can be lower during decommissioning than during regular operation.

The objective of ISOE is to improve the management of occupational exposures at nuclear power plants by exchanging broad and regularly updated information, data and experience on methods to optimise occupational radiation protection. This publication establishes requirements for the safe decommissioning of a broad range of facilities: nuclear power plants, research reactors, nuclear fuel cycle facilities, facilities for processing naturally occurring radioactive material, former military sites, and relevant medical, industrial and research facilities.

Decommissioning is the last step in the lifetime management of a facility. It must also be considered during the design, construction, commissioning and operation of facilities. This publication establishes requirements for the safe decommissioning of a broad range of facilities: nuclear power plants, research reactors, nuclear fuel cycle.

Occupational Radiation Exposure at Commercial Nuclear Power Reactors and Other Facilities (NUREG). Decommissioning of Nuclear Facilities One of the most important tasks related to the dismantling of nuclear facilities is to cope with the amount of residues and waste arising.

After a nuclear facility is shut down for the final time, the next steps involve reducing the sources of hazard in a systematic and progressive way.

This increase of dose rate can justify the taking of corrective measures to reduce operators’ occupational by: 2. Throughout the world, occupational exposures at nuclear power plants have been steadily decreasing for over a decade.

Regulatory pressures, particularly after the issuance of ICRP Publication 60 intechnological advances, improved plant designs, and improved water chemistry and plant operational procedures have contributed to this.

Good operating practice is for site and waste remediation to be carried out on a continuous basis during ore recovery, thereby reducing the time and costs for final decommissioning, remediation, and reclamation. Project management should not be stagnant, but should evolve in an iterative manner to take full advantage of international advances.
