Summary

In this episode of Energy Conversations, host Thokozile Zambane interviews Loyiso Tyabashe, Group CEO of Necsa, South Africa’s Nuclear Energy Corporation. The discussion covers Necsa’s history, its role in the nuclear value chain, and the revival of the Pebble Bed Modular Reactor (PBMR). Tyabashe explains the government’s decision to transfer PBMR intellectual property from Eskom to Necsa, aiming to re-enter the SMR market. He details the Integrated Resource Plan (IRP) target of 5,200 MW of new nuclear capacity by 2039, with Necsa tasked to develop a demonstration SMR. The conversation explores the technical aspects of SMRs, their advantages for smaller grids, and the potential to repurpose coal infrastructure. Tyabashe emphasizes the importance of skills development, noting that nuclear plants require more artisans than physicists. He also addresses safety, transparency, job creation, and global clean energy financing. The episode concludes with optimism about South Africa’s nuclear future and its potential to export SMR technology to the African continent.
