Necsa achieves a first for the SA nuclear industry

25 JANUARY 2018

The South African Nuclear Energy Corporation (Necsa) has supplied the first locally produced safety related ASME III designed and certified Air Receiver Pressure Vessel to Eskom-owned Koeberg.

The Nuclear Manufacturing (NM) was achieved within the Pelindaba Enterprise Division of Group Necsa.

The Air Receiver Vessel was specified by Koeberg to be a safety class 2 nuclear vessel in a comprehensive Registered Professional Engineer (RPE) certified Design Specification.

Necsa explained: "The purpose of the vessel is to pressurise the 20m containment building equipment hatch seals inter-space under all operating conditions in order to provide assurance of the condition of the seals.

"The vessel loading conditions associated with design, test, construction, operating and upset states were evaluated. The upset conditions include a postulated seismic event. It was shown that the vessel maintains structural integrity and function throughout all events."

Koeberg Project Manager Neelan Rama and Design Engineer Mark Vernon collaborated throughout the project with the Necsa project team, which ensured alignment of code interpretations implemented and alignment in applying design input requirements as specified.

The NM teams consist of various stakeholders that were involved in the successful delivery of the vessel including, TÜV Rheinland performing ASME Authorized Inspection Agency services; Ezekoye Engineering Services LLC providing the RPE Design Specification review services and Unisont Engineering, Inc. that undertook the RPE Design Report review services.

"The capabilities demonstrated by NM in supplying the first N-stamp vessel in South Africa creates the opportunity for extending NM’s services and projects specifically where safety related equipment and services are required," Necsa added.

The South African Nuclear Energy Corporation (Necsa) marked an important milestone on Wednesday when it formally handed over the first locally-designed and manufactured safety-critical nuclear component, fully certified, to national power utility Eskom for use in the Koeberg nuclear power plant, near Cape Town. Necsa has a Nuclear Manufacturing unit within its Pelindaba Enterprises division.

 

The component is an air receiver vessel. The specifications and overall design were drawn up by a team at Koeberg, while the detailed design and computer modelling was carried out at Pelindaba Enterprises. Design and manufacture were monitored by global quality assurance organisation TUV and by the South African National Nuclear Regulator.

 

"This is our first delivery of a fully-qualified product," affirmed Pelindaba Enterprises group executive (Mr) Ruby Ramatsui. "This has confirmed we are ready to supply the rest of the world."

 

"This is the first ASME III certified vessel certified and manufactured in South Africa," highlighted Necsa Pelindaba Enterprises chief engineer Jaco van der Merwe. ASME (originally the acronym for the American Society of Mechanical Engineers) Chapter III contains the globally accepted quality standards for pressure vessels manufactured for nuclear applications.

 

South Africa had previously had some nuclear manufacturing capabilities, but, with the end of the apartheid era and of the concomitant sanctions, these were not economically viable and were shut down. "This is a process of restarting what we had before," explained Ramatsui. But this time, the aim was to be commercially competitive. He pointed out that other countries had successfully localized nuclear technology and created competitive nuclear industries. South Korea was a particularly good example. "We can do it!" he assured.

 

The fabrication of the air receiver vessel was the result of a Necsa vision to become a manufacturer of nuclear products for the nuclear industry in South Africa and internationally, pointed out Van der Merwe. The first step was to build a team of skilled engineers and artisans (such as boilermakers and welders). Once that team had been built, the next step was to check quality assurance and management standards and procedures, and identify gaps and shortfalls. These gaps were then filled and the shortfalls rectified and the team members trained up to the very high required standards.

 

ASME was then invited to send an audit team to Pelindaba Enterprises. They did so, and the result was the granting of ASME III certification, with the requisite certificates for nuclear design and manufacturing. "Nuclear Manufacturing [within Pelindaba Enterprises] has been appointed as an approved [nuclear] supplier. ... [A]ccording to ASME standards," stated Van der Merwe.

"We are pioneering a sustainable path for the African nuclear industry," stressed Ramatsui. "We will continue to build capacity in cooperation with Eskom and local industry."

Another excellent performance by a Necsa team!

We are proud to announce that the Diffraction Group of the Radiation Science Department of the R&D Division made it to the finals of the NSTF awards in the category “Research leading to Innovation by a Corporate Organisation”. As such the team members will already receive certificates of merit even though the over-all winning team still has to be announced at a prestigious function on 30 June 2016.

The team was nominated for the development of two world-class neutron diffraction instruments, MPISI and PITSI, at the SAFARI-1 research reactor. SAFARI-1 is a national asset with an impeccable safety and operational record. The development of world-class neutron instruments for niche applications is important to expand its institutional value even further. The resulting suite of non-destructive experimental techniques offered by the two new instruments benefits many materials related research fields. This is made possible because neutrons probe deep into materials to reveal information about atomic and magnetic properties at the micro-structural level, providing a powerful diagnostic for researchers in fields such as advanced manufacturing, metallurgy, nuclear materials and mineral beneficiation, all disciplines at the root of a knowledge economy.

The team of multi-disciplinary subject experts was led by Dr Venter, an expert in neutron diffraction science. The respective roles played were:

  • AM Venter: Scientific group leader.
  • PR van Heerden: Development and integration of mechanical subsystems.
  • JC Raaths: Integration of electronic and neutron detector systems.
  • D Marais: Customisation of software control system and development of data acquisition and treatment modalities.  
  • M Hayes, TP Ntsoane and ZN Sentsho: Scientific commission, testing and validation
