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

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

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

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)

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

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)

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

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?
![Page 12: TSO: Concept, Principles & Approach Concept, Principles & Approach ... analysis (computer ... Since TSOs are very different; the concept is still not](https://reader031.vdocument.in/reader031/viewer/2022022506/5ac1156b7f8b9a213f8cb510/html5/thumbnails/12.jpg)

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)

TSO in NNR Framework
The evolution of the use of TSO’s varies globally depending
on many factors:
① In most countries @ 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

• 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

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…
