HIGH-TEMPERATURE MATERIALS

15.12.1 Technical Issues A feature of many of the innovative future designs is their relatively higher outlet temperatures compared with current generation plant. The safety envelopes of many of the component materials may not extend to these temperatures in which case new materials will need to be developed and qualified. Additionally many of the coolants may erode or corrode the […]

The Future of Nuclear Power

J. N. Lillington During the last century, nuclear power has been established as a reliable source of energy in the major industrialised countries. It has a potentially important role in the future since it does not contribute to the production of ‘Greenhouse’ gases; a growing concern of continued fossil fuel power generation. The time is now appropriate to review the […]

Operational Safety

3.1. INTRODUCTION/OBJECTIVES This chapter addresses the issues of operational safety for existing nuclear power plants. It concerns safety throughout all aspects of power plant operation and a number of topics are covered. There are diverse issues, some of which have already been introduced in the previous chapter. The management of radioactive waste is a particular concern and must be resolved, […]

ENRICHMENT

Current enrichment technologies are based on either gaseous diffusion or centrifuge methods. Other methods based on curved nozzle separation and laser enrichment have also been explored (Leclercq, 1986). The capital costs of enrichment plants are relatively high; around 6% of the total generation cost (Bertel and Wilmer, 2003).

PERFORMANCE-RELATED IMPROVEMENTS

7.5.1 Availability Improved performance of current plants has been discussed earlier in this book. This is being achieved by better ways of processing information on the plant condition, e. g. components, better surveillance and diagnostics. The causes of reduced level of performance can be determined by analysing the better data obtained and improved management techniques can be implemented. Clearly these […]

Germany

Germany has 13 pressurised water reactors and 6 boiling water reactors currently in operation, contributing to about one-third of the country’s electricity generation (World Nuclear Association, 2003). Following the reunification of Germany in 1990, all the Russian-designed VVER plants in the East were shutdown for safety reasons.

Embrittlement of Materials

The ageing materials European strategies (AMES) network was set up by the EC to bring together expertise on nuclear reactor materials (Gerard et al., 2001; Sevini et al., 1999). The most important area for research for effective plant life extension and management is the reactor pressure vessel (RPV), but metallic components in general (e. g. internals, pressuriser and piping) were […]
