Technologies for improving current and future light water reactor operation and maintenance: Development on the basis of experience. Proceedings of a technical committee meeting

Abstract

Application of efficient technologies for improving operation and maintenance of nuclear power plants is an important element for assuring their economic competitiveness with other means of generating electricity. The competitive environment, which nuclear power plant operators face in many countries as a result of de-regulation of the electricity market, imposes cost pressures that must be met while at the same time satisfying stringent safety requirements. Further, as currently operating plants age, proper management includes development and application of better technologies for inspection, maintenance and repair. For future plants, the opportunity exists during the design phase to incorporate design features for performing efficient inspection, maintenance and repairs. Despite the prevailing low prices of fossil fuels, the generation costs of nuclear electricity continue to be competitive with electricity generation costs from fossil-fuelled plants for base load generation in several countries. For nuclear power, the capital investment component of electricity generation cost is relatively high, while the nuclear fuel cycle cost is - and is expected to remain - relatively low. The prices of fossil fuels are fairly low today but are likely to increase over the long term because the resource is limited. Moreover, governments may introduce incentives to reduce the use  More>>

The competitive environment, which nuclear power plant operators face in many countries as a result of de-regulation of the electricity market, imposes cost pressures that must be met while at the same time satisfying stringent safety requirements. Further, as currently operating plants age, proper management includes development and application of better technologies for inspection, maintenance and repair. For future plants, the opportunity exists during the design phase to incorporate design features for performing efficient inspection, maintenance and repairs. Despite the prevailing low prices of fossil fuels, the generation costs of nuclear electricity continue to be competitive with electricity generation costs from fossil-fuelled plants for base load generation in several countries. For nuclear power, the capital investment component of electricity generation cost is relatively high, while the nuclear fuel cycle cost is - and is expected to remain - relatively low. The prices of fossil fuels are fairly low today but are likely to increase over the long term because the resource is limited. Moreover, governments may introduce incentives to reduce the use of fossil fuels in order to protect the environment. In many countries, nuclear utilities are experiencing increased competition with other sources of electricity production due to deregulation of the electricity market, and nuclear plant operators can no longer pass along the generation costs to consumers through regulated electricity rates. This competitive environment has significant implications for plant operations to achieve efficient use of all resources, and to effectively manage plant activities including outages and maintenance. Over the past several years, steady improvements have been experienced in nuclear power plant operation and maintenance. Worldwide, the average energy availability factor has increased from approximately 70 percent in 1989 to 79 percent' in 1998, with some utilities achieving significantly higher values. This is being achieved through integrated programmes, including personnel training and quality assurance, from improvements implemented in plant systems and components, and from improvements in outage duration for maintenance, refuelling, and other scheduled shutdowns, as well as forced outages. International co-operation is a key role in this success. The various programmes of the World Association of Nuclear Operators (WANO) to exchange information and encourage communication of experience, and the activities of the IAEA including projects in nuclear power plant performance assessment and feedback, effective quality management, and information exchange meetings on technology advances, are important examples of international co-operation to improve the performance of nuclear power plants. This IAEA Technical Committee meeting (TCM) was convened to provide a forum for information exchange on technologies for improving plant operation and maintenance which can contribute to enhanced economic competitiveness of LWRs, and on on-going or planned technology development expected to achieve further improvements. Information exchange of recent positive experience on development and/or implementation of technologies that have resulted in reduced operation and maintenance costs of LWRs, and information on on-going or planned activities, was strongly encouraged.}
