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?

Mzesı Holdings

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)

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

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

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

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…
