Young Nuclear Professionals

Company Affiliates

VOL 67

Russian energy group, Rosatom, signed a Memorandum of Understanding on support and cooperation with the “African Young Generation in Nuclear” (AYGN) organisation, in August.

Rosatom has undertaken to offer support and knowledge-sharing to “AYGN”, a new pan-African forum for young professionals working in the nuclear sector.

Gaopalelwe Santswere, President of African Young Generation in Nuclear, says the non-profit organisation began forming in 2014 and was formally launched in Nairobi, Kenya, earlier this year. With a membership of over 350 professionals working in the nuclear sector across Africa, the organisation works with industry partners to raise awareness and skills among young people around science and technology, and nuclear power in particular. “Africa is the new nuclear frontier, and we are working to equip the continent’s young professionals with the skills they will need in this new environment.”

Technology readiness level

Description

1. Basic principles observed and reported

This is the lowest “level” of technology maturation. At this level, scientific research begins to be translated into applied research and development.

2. Technology concept and/or application formulated

Once basic physical principles are observed, then at the next level of maturation, practical applications of those characteristics can be ‘invented’ or identified. At this level, the application is still speculative: there is not experimental proof or detailed analysis to support the conjecture.

3. Analytical and experimental critical function and/or characteristic proof of concept

At this step in the maturation process, active research and development (R&D) is initiated.

This must include both analytical studies to set the technology into an appropriate context and laboratory-based studies to physically validate that the analytical predictions are correct. These studies and experiments should constitute “proof-of-concept” validation of the applications/ concepts formulated at TRL 2.

4. Component and/or breadboard validation in laboratory environment

Following successful “proof-of-concept” work, basic technological elements must be integrated to establish that the “pieces” will work together to achieve concept-enabling levels of performance for a component and/or breadboard. This validation must be devised to support the concept that was formulated earlier, and should also be consistent with the requirements of potential system applications. The validation is “low-fidelity” compared to the eventual system: it could be composed of ad hoc discrete components in a laboratory.

5. Component and/or breadboard validation in relevant environment

At this level, the fidelity of the component and/or breadboard being tested has to increase significantly. The basic technological elements must be integrated with reasonably realistic supporting elements so that the total applications (component-level, sub-system level, or systemlevel) can be tested in a ‘simulated’ or somewhat realistic environment.

7. System prototype demonstration in a space environment

TRL 7 is a significant step beyond TRL 6, requiring an actual system prototype demonstration in a space environment. The prototype should be near or at the scale of the planned operational system and the demonstration must take place in space.

8. Actual system completed and ‘flight qualified’ through test and demonstration (ground or space)

In almost all cases, this level is the end of true ‘system development’ for most technology elements. This might include integration of new technology into an existing system.

9. Actual system ‘flight proven’ through successful mission operations

In almost all cases, the end of last ‘bug fixing’ aspects of true ‘system development’. This might include integration of new technology into an existing system. This TRL does not include planned product improvement of ongoing or reusable systems.

Don’t be a slave to technology readiness levels. We adopt what we can from level five and up

The way forward for South Africa

Having explored and outlined the challenge facing South African students, educators, government and businesses, it is clear that a multi-layered approach is required.

In addition, each stakeholder has a very unique role to play, and definitive hurdles to overcome.

Students, for example, need to readjust and reset certain expectations and ideas of the workplace, while educators need to become more open to the digital realm and the new set of tools it is proffering.

Commerce and industry need to come to the fore in their relationship with all parties more involved and committed to the changes that need to be made.
