BERR is responsible for co-ordinating UK policy on international nuclear safety issues, liaison with the IAEA Department of Nuclear Safety and Security and the submission of the UK's report under the Convention on Nuclear Safety (CNS).
Fifty-three countries and the European Commission (referred to as contracting parties) have ratified the Convention on Nuclear Safety which came into force in the Autumn of 1996. The Convention aims, through a triennial process of a report, questioning and peer review at an international meeting, to assist in the continual process of raising standards of civil nuclear safety world-wide.
Each country is required to submit a detailed written report and undergo peer review during the Review Meetings, explaining how they fulfil the Articles of the Convention relating to e.g. their legislative and regulatory framework for nuclear safety, financial and human resources for nuclear safety, assessment and verification, radiation protection, emergency preparedness and details of their procedures for siting, design and construction and operation of civil nuclear power plants.
The administration of the Convention in the UK is managed by the Health and Safety Executive (HSE), which produces the UK report under the Convention. BERR is responsible for the submission of the UK report and submitted the current report (the fourth report) in September 2007.
The Peer Review meetings take place at approximately three-yearly intervals. The first was held in Vienna in April 1999, the most recent took place in April 2008 in Vienna.
