Peter Becker was appointed by the Minister as a non-executive director of the National Nuclear Regulator Board on 10 June 2021, representing communities affected by nuclear activities under section 8(4)(a)(iii) of the National Nuclear Regulation Act 47 of 1999. He was nominated by civil society organizations including the Koeberg Alert Alliance (KAA), where he served as spokesperson. Shortly after his appointment, Becker was quoted in an Energize magazine article on 30 June 2021 making statements critical of nuclear activities at Koeberg Power Station and the proposed Thyspunt site. He subsequently convened a virtual meeting with civil society organizations on 22 July 2021 and made internal inquiries to the Board about long-term operation issues at Koeberg. The Board obtained a legal opinion concluding Becker had committed misconduct by conflating his activist role with his Board duties. The Minister suspended Becker on 18 January 2022 and, after representations, discharged him on 25 February 2022 for misconduct based on conflict of interest under section 9(1)(c) of the Act. Before making representations, the Minister made public statements on 3 February 2022 suggesting he had already decided to remove Becker.
