Providing for the protection of persons, property & the Environment against nuclear damage 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)

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

52. Providing for the protection of persons, property & the Environment against nuclear damage Background  The Public Finance Management Act, 1999 (Act No. 1 of 1999, as amended, requires the directors to ensure that the NNR keeps full and proper records of its financial affairs.  The annual financial statements must fairly present the NNR’s financial position, its performance against predetermined objectives and in terms of Generally Accepted Accounting Practice. ANNUAL FINANCIAL STATEMENTS

53. Providing for the protection of persons, property & the Environment against nuclear damage INCOME STATEMENT  The NNR generated Revenue from Authorisation fees of R47,647m in comparison to R44,531m in the previous financial year. This represents an increase of 7%, mainly due to the improvement in the system of internal controls around revenue collection.  Overall increase in operation income of 1% from R52,598m in previous financial year to R53,256m in 2006, this performance is despite a reduction of R2,650m in the State Grant from R8,067m in 2005 to R5,417m.  Total operating expenditure for the year amounted to R 52,271m in comparison to the budget R56, 941m. This represents an under- expenditure of R4,671 resulting from unfilled 15 vacancies at year end. ANNUAL FINANCIAL STATEMENTS
