| P137 | Annex 1 | Rewording of OCNS description to reflect move from DTI to HSE and replacement of DTI by DBERR | OCNS conducts its regulatory activity on behalf of the Secretary of State for Business, Enterprise and Regulatory Reform under the authority of the Nuclear Industries Security Regulations 2003 (NISR). The security regime's purposes are to prevent theft of nuclear material or sabotage of nuclear facilities, to safeguard sensitive nuclear technology and information and thereby to help prevent nuclear proliferation, and to safeguard other protectively-marked Government information held by the civil nuclear industry. It also regulates movements of nuclear material both within the UK and on board UK flagged vessels worldwide. In pursuit of these purposes, OCNS sets and promulgates standards to the nuclear industry in the areas of physical, personnel, information and IT security, and carries out inspections to check for compliance with these standards. NII and OCNS have a common interest in ensuring that security and safety arrangements are adequate and effective in preventing the theft or misuse of nuclear material, and actions by individuals or groups, causing harm or damage. These arrangements contribute to the wider aims of protecting the health and safety of employees, contractors and general public from the hazards of ionising radiation, promoting the Government's nuclear non-proliferation obligations and the protection of national security. In April 2007, the Office for Civil Nuclear Security became a part of the Nuclear Directorate of HSE, through a Government Transfer process and in line with the Hampton Review. The activities of the OCNS under these new arrangements are influenced by a Memorandum of Understanding. This Memorandum of Understanding sets out the arrangements agreed between the Health and Safety Executive (HSE) and the Department of Trade and Industry (DTI - now DBERR) on civil nuclear security following the transfer of the Office for Civil Nuclear Security (OCNS) from DTI to HSE. The purpose of the Memorandum is to set out the arrangements under which HSE will perform the functions of the Secretary of State for Department of Business, Enterprise and Regulatory Reform set out in the Agreement under Section 13(1)(b) of the Health and Safety at Work etc Act 1974. As an integral part of the Nuclear Directorate within HSE, the pursuit of safety and security and the common interests flowing from these are delivered by: a) ND Safety Divisions provide information to OCNS, derived from their knowledge of nuclear licensed sites and their safety cases, to enhance the latter's awareness of nuclear safety and radiological safety, both generally and in relation to vulnerable high-risk plant and systems at particular sites. OCNS provides security information in its possession to ensure that health and safety considerations are best managed at licensed nuclear sites, subject to any statutory or confidentiality restrictions; and b) within ND, consultation and the exchange of information at the earliest practicable stage in the consideration of relevant new projects or proposed changes at licensed nuclear sites, or following a significant breach of licence conditions or regulated security arrangements, with a view to identifying the necessary safety and security arrangements or changes before requirements are placed on licensees. |
