6. Conclusion and Findings

This report has shown clearly that despite the ongoing reassurances from the nuclear energy industry and Eskom in particular, that there is cause for great concern regarding both the current operations at Koeberg Nuclear Power Station as well as the proposed PBMR.


Safety at Koeberg

Despite several investigations by the independent media related to concerns around the operations of Koeberg and the development of the PBMR (Special Assignment, 1998) little progress has been made in resolving these incidents in a satisfactory manner. The report highlights the number of incidents that were not reported publicly until pressure was exerted on Eskom.

There is no satisfactory explanation from either Eskom or the NNR as to the history of safety breaches and incidents, and why Eskom has not been ordered to cease its operations until compliance is achieved. In stark contrast to this are the glowing accolades presented to Eskom by the IAEA and the Framatome Operators Group regarding their operations safety record. However, these events must be placed into context and seen against the recent revelations regarding the way in which Eskom has dealt with the Lockwood case.


Health track record

Recent revelations by former Eskom employee Ron Lockwood shed new light on the claims made by numerous ex-Eskom workers that there is cause for concern regarding the exposure of workers to radiation. The cover-up of his health conditions call for a full and independent enquiry into health monitoring at Koeberg.

General trends and research highlighting the increasing evidence that a range of ailments (in particular breast cancer, leukaemia, lymphoma, etc) are becoming more pronounced in certain areas especially those close to nuclear installations. Our report shows, that despite Eskoms denial that these studies bear any relevance to the development of the PBMR and its impacts, the opposite is in fact true, especially given the current trends highlighted with regard to the performance of the local and international nuclear industry. The absence of radiological monitoring in South Africa is also a cause for concern highlighted in our report.


The PBMR and critical flaws

Despite reassurances from Eskom and the Pebble Bed Company that the PBMR design is ?“walk away safe?”, there are concerns at the international level that all is not well. Inability to deal adequately with safety concerns and waste issues and the fact that the PBMR will generate 10 times more waste than current reactor designs, are some examples of the issues highlighted in our findings.

Research conducted by the Nuclear Regulatory Commission and local and overseas experts, show that the safety features touted by Eskom require much deeper examination. Lyman (2001) also highlights the areas of the PBMR safety that are exposed, especially the vulnerability to graphite fires and the floored assumptions regarding the temperature at which the fuel remains stable.

Earthlife Africa is calling for a full, independent review of the PBMR safety and design parameters.

Our report substantiates our call for a full independent judicial review of the operating, health & medical and safety records of Koeberg, and a full independent review of the Pebble Bed Modular Reactor.
