1 TSO: Concept, Principles & Approach Dr Simanga Alex Tsela Mzesi Energy 1 st Nuclear Regulatory Information Conference 06/10/2016

2 CONTENTS Introduction Concept & Principles Conclusions 2

3 Premise 1 TSO approach adopted by NNR is new for South Africa Developing Local TSO capacity while still working with International TSO 3

4 Premise 2 The architecture: concept, principles, & approach for use of TSO is still not consolidated globally It means different things, and its utilization varies 4

5 Thought Question Does TSO s exist only to enhance regulatory function or as an essential contributor to the nuclear value chain? 5

6 WHAT IS A TSO Definition of TSO varies from country to country IAEA: Technical and Scientific Support Organisation (TSO)- 1 Provides technical and scientific support to regulatory authorities or the industry 2 Also advise Governments 3 TSO could also refer to Design Authority for a Vendor Services to Regulatory authority, Industry, and Government ( Our understanding of regulatory independence requires separation of services between Regulator & Industry) 6

7 WHY IS TSO NEEDED Success factors for expanded deployment of nuclear power 1 Technological advancements in future nuclear reactors 2 Public understanding and acceptance of nuclear power 3 Regulatory effectiveness and efficiency in particular the licensing/authorisation processes TSOs provides an invaluable bridge from current nuclear status of a country to a sustainable future expanded nuclear power 7

8 WHY IS TSO NEEDED Scenario: Nuclear Program in South Africa Operation Operation Siting >40yrs Siting Much has changed in 40 years - technology, people, standards, - What future we want- 40yrs from now 8

9 WHY IS TSO NEEDED Several instances arises requiring a TSO, inter alia, 1 Regulatory R&D; Continuous professional development 2 Specialized expertise at different times of regulatory value chain (new design, site selection, modifications, etc) 3 Response to legal changes that require new regulatory processes (criteria, requirements, guidance) 4 Independent verification, detailed/advanced technical analysis (computer simulations, modeling) 5 Augmenting for lack of specific resources 6 Platform for neutral technical dialogue between regulator, stakeholders including the media (public confidence building) 9

10 NATURE OF TSO s POSSIBILITIES Nature of Regulatory external support within a country 1 Advisory bodies/committees- specific issues 2 Dedicated organisations- regular services to Regulator 3 Laboratories, research centres, academic institutions, etc Nature of Regulatory external support beyond borders 1 International organisations (eg: IAEA, ICRP, etc) 2 Regulatory bodies of other countries 3 Regulatory bodies of vendor countries 4 International TSO s 10

11 CONCEPTUAL THINKING Since TSOs are very different; the concept is still not consolidated globally, we need to develop the appropriate doctrine for TSO s for instance: Is a TSO only a resource to Regulator or industry where they lack resources or is it a function on its own right within the nuclear value chain to promote efficiency, effectiveness and public confidence in nuclear safety & security? 11

12 CONCEPTUAL THINKING Several Models: 1 Model 1: develop it to support where Regulators lack resources (direct extension of the Regulator) 2 Model 2: develop it as a significant player in nuclear value chain for achieving a high level of nuclear safety, security, public confidence, nationally (Independent, also serves as platform for dialogue for various stakeholders) 12

13 TSO in NNR Framework The evolution of the use of TSO s varies globally depending on many factors: 1 In most start of nuclear program, a short term solution is to use international TSO s 2 For NNR the developmental use of local TSO is new, for years the approach has been to rely on international TSO s (eg: TUV, etc) 3 The NNR model thus far: combination of both Independent entities and direct extension of NNR 13

14 MZESI 100% wholly black owned, managed, and operated Holding company with two subsidiaries: Mzesi Energy & Mzesi Academy 14

15 MZESI Mzesi has a core team of permanent employees Mzesi s partners with local and international organisations and individuals to supply specific resources as needed to complement the internal team on a retainer basis The partnership is also used to develop further local capacity and competence 15

16 TSO Resources Partnerships: Mzesi has partnered with organisations such as: HSB Excel Services AdSTM UJV PSU Several individual consultants Therefore Mzesi has access to resources with a wide range of skills such as: Nuclear safety and safety analyses Radiation Protection Engineering Reactor physics Plant operations Licensing Manufacturing inspections 16

17 TSO Projects As the TSO Mzesi has been supporting the NNR on various projects with specific requirements Some project are completed, while a few others are active 17

18 TSO Projects Establishment of the Radio-analytical laboratory 18

19 TSO Projects Steam Generator Replacement Manufacturing Oversight 19

20 Mzesi Academy Mzesi believes that nuclear technology provides a strategic tool for South Africa, as a component of the energy mix. Mzesi has however identified a number of gaps pertaining to the industry: Mentorship for new entrants in the nuclear industry Demystification of nuclear technology / Public awareness Provision of specific training courses for professional enhancement programmes: Nuclear security Nuclear Safety Nuclear technology for non-nuclear professionals Laboratory analyses training 20

21 Mzesi Academy 21

22 Conclusions 1 TSO s are invaluable for nuclear safety, security, & public confidence building 2 The NNR has chosen a path that is not the easy route, however it will ensure local sustainability in TSO capacity and capability, and hence Regulatory effectiveness & efficiency 3 Nothing is without its own dynamics 22
