  4. 1. MANDATE OF NNR • The National Nuclear Regulator Act ( Act No 47 of 1999) (NNRA) established the National Nuclear Regulator (NNR). It repeals the Nuclear Energy Act (NEA) ( Act No 131 of 1993) which was applicable to the erstwhile Council for Nuclear Safety (CNS). • The NNRA came into force on 24 February 2000. • The previous NEA legislated activities of both the Atomic Energy Corporation of South Africa and the CNS. The promulgation of the NNRA, which deals exclusively with the regulation of the nuclear industry, provides for the separation of the promotional and Regulatory functions in the nuclear industry in South Africa. • The promotional aspects of nuclear activities in South Africa are legislated by the Nuclear Energy Act (Act No 46 of 1999) Providing for the protection of persons, property & the Environment against nuclear damage

  5. MANDATE Cont … The mandate of the NNR is to “……Provide for the protection of persons, property, and environment against nuclear damage, through …” Providing for the protection of persons, property & the Environment against nuclear damage

  6. OBJECTS OF NNRSection 5 of the NNR Act • Exercise regulatory control over nuclear installations, vessels propelled by nuclear power or having radioactive material on board and actions through the granting of nuclear authorisations. • Provide assurance of compliance of conditions of nuclear authorisations through compliance inspections. • Fulfil national obligations in respect of international instruments. • Ensure that provisions for an emergency plan are in place. Providing for the protection of persons, property & the Environment against nuclear damage

REGULATORY OVERSIGHT OF KNPS • The current KNPS authorization, Nuclear Installation Licence NL-1 Variation 16, issued to Eskom in terms of section 23 of the NNR Act, is subject to 16 conditions, including specific licensing requirements , which form the basis for the NNR regulatory oversight of Koeberg in protecting the public, property and the environment. Providing for the protection of persons, property & the Environment against nuclear damage

  18. REGULATORY OVERSIGHT OF KNPS SAFETY ASSURANCE ACTIVITIES • Safety assessments • As in previous years a major part of the NNR’s work associated with KNPS related to the verification of nuclear safety through conducting of in depth safety assessments related to plant modifications, plant condition management and probabilistic risk assessment. Providing for the protection of persons, property & the Environment against nuclear damage

  19. REGULATORY OVERSIGHT OF KNPS SAFETY ASSURANCE ACTIVITIES (Cont…) • Occupational Exposure to radiation • Radiation exposures to personnel working at Koeberg are subject to control by the operational radiation protection programme which ensures that control within the annual individual dose limit, set by the NNR, is achieved . • In terms of occupational exposure, the worker doses over the reporting period were within the regulatory limits. • Public Exposure to radiation • Public exposure to radiation is controlled within strictly defined limits, set by the NNR, through the implementation of a radiological emission and effluent management programme, which ensures that the discharges of radioactivity from Koeberg result in no significant risk to the public • There were no concerns regarding the safety of the public living around KNPS during the reporting period. Providing for the protection of persons, property & the Environment against nuclear damage

  20. REGULATORY OVERSIGHT OF KNPS SAFETY ASSURANCE ACTIVITIES (Cont…) • Emergency Planning and Preparedness • The NNR conducted a full scale nuclear emergency exercise at the KNPS on 15 February 2006. • Overall the response of the licensee (Eskom) and the intervening organisations was satisfactory. • The NNR umpires identified a few areas of concern and potential areas for improvement of the Koeberg Emergency Plan. • Some aspects of the “late phase” plan need further improvement and testing. • The exercise report indicating the NNR graded findings and expected dates for implementation of corrective actions was sent to Eskom and the relevant authorities. • NNR is monitoring implementation of identified corrective actions Providing for the protection of persons, property & the Environment against nuclear damage
