Risks of Life-time Extension of Ageing Nuclear Power Plants - INRAG
- Life-time extensions and the operation of ageing nuclear power plants increase nuclear risks in Europe.
- Ageing processes increase the risk of transients and accidents.
- All pan-EU ageing power plant concepts are, in practice, outdated in terms of safety.
- Many nuclear power plants are operated beyond the limit of the original technical design and at an outdated technical level.
- New threats have emerged.
- To justify life-time extensions original safety margins are reduced.
- The old plants cannot be licensed according to today’s standards.
- The statement that the safety of old nuclear power plants has been continuously improved by retrofitting is misleading.
- There are limits to retrofitting on principle. Major conceptual weaknesses of old nuclear power plants remain.
- The possibilities of ageing management are limited.
- Retrofitting and repairs in old plants lead to additional risks
- Lack of documentation and loss of know-how and know-why make it difficult to assess the safety of old plants.
- The risks of old plants must be known in order to assess their safety.
- Lack of transparency makes it difficult for third parties to assess risks.
- There is no established possibility for transboundary participation, although the risks may have transboundary consequences.
- There is no independent international review body and no internationally binding rules for the implementation of safety requirements for old plants.
