The future of nuclear power installations
Nuclear reactors like most other industrial plants do not last for ever and, at the time of writing (1988) plans are in operation for decommissioning the early Magnolia reactors. The Berkeley one, mentioned in Fig. 7.6 on page 80 is one of the first for demolition. The first advanced gas-cooled reactor (AGR) which was built at Wind scale as a model for the second generation of reactors was closed down in 1981. A new generation of reactors is now coming into operation. One of the main problems in closing down a reactor is the safe disposal of radioactive waste. Also some parts of the plant will have to be enclosed in thick concrete for more than a century to allow for a safe natural decay of their natural activity.
