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.

MODELLING

Neutron transport in the fission range of heavy metal energies has been studied for many years within the nuclear reactor industry. In ADS, the situation is more complicated than in conventional nuclear reactors. In this case, there is dual transport modelling required, the transport of medium energy charged particles in the energy range 1-3 GeV in the spallation target, and […]

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 […]

Continued Operation of Existing Plant

2.1. INTRODUCTION/OBJECTIVES There are approximately 440 nuclear reactors in operation in about 30 countries worldwide. For the continuation of nuclear power, the most important requirement is the safe and efficient operation of these reactors. This chapter summarises the principal issues associated with the operation of current generation nuclear power plant. These relate to the incentives for continued nuclear generation (including […]

SAFETY IMPROVEMENTS

Within present day generation plants, there is a continuing requirement to improve safety and performance. There has been a major investment in experimental and theoretical programmes of work to support this objective. Component research has been carried out to back-fit safety systems on older reactors. Better understanding has led to the development of additional accident prevention and mitigation guidelines. It […]

Waste Management and Decommissioning

6.1. INTRODUCTION/OBJECTIVES There are still major issues associated with the disposal of nuclear waste. There are bodies of opinion within the nuclear industry, regulators and many experts that believe solutions exist for all stages, but there is considerable public mistrust. This is fuelled since in many countries, there is no position on the final disposal strategy for long lived high-level […]
