项目摘要

For infrastructure intensive industries such as nuclear power generation it is frequently more cost effective to extend the operational life of aging assets rather than enter a new build programme. For new build, new design reactors the approach would be to plan for a long operating life throughout the design and development stages.Safe and cost effective management of the infrastructure's aging process requires a robust initial system design together with the implementation of a focussed maintenance regime which dynamically adjusts to address the changing system needs throughout their operation. A third option to control risk is through the generation of a grace period in the event of an uncontrolled accident initiation. During this period there would be a high chance of restoring the critical system functionality.The safety critical systems, design and maintenance options would focus on preventing an uncontrolled hazardous event. The generation of a grace period would provide an opportunity to make the reactor safe even when the accident sequence had progressed.Through the three features described the project will investigate the most cost-effective way to produce safe and reliable life extension for the reactors. Both current aging nuclear reactors and also those in the design phase would be considered. For current reactors where the design is fixed, the system state will be controlled through the effective use of maintenance. The maintenance will vary throughout phases in the operational life-time to respond to the different aging processes encountered on the plant. In this context maintenance will include: servicing, testing/inspection, reactive repairs, preventive replacement due to use, age or condition and also renewal. For new reactor designs the full range of defence options can be considered with the expectation of increasing the operating life for longer than the current design life specification.By embedding the modelling methodology into a decision support framework the different risk defence options will be considered to produce cost effective selections for safe and reliable plant performance.The methodology produced will be demonstrated by application to reactor systems.
对于核电等基础设施密集型行业,延长老化资产的使用寿命往往比进入新的建设计划更具成本效益。对于新建造、新设计的反应堆,方法是在整个设计和开发阶段规划较长的运行寿命。基础设施老化过程的安全和成本效益管理需要稳健的初始系统设计以及实施集中维护制度,该制度在整个运行过程中动态调整以满足不断变化的系统需求。控制风险的第三种选择是在发生不受控制的事故时,通过产生宽限期。在此期间,恢复关键系统功能的可能性很大。安全关键系统、设计和维护选项将侧重于防止不受控制的危险事件。宽限期的产生将提供一个机会,使反应堆安全,即使事故序列已经进展。通过所述的三个特点,该项目将调查最具成本效益的方式,产生安全和可靠的反应堆寿命延长。将考虑目前老化的核反应堆和处于设计阶段的核反应堆。对于设计固定的当前反应堆,将通过有效使用维护来控制系统状态。维护将在运行寿命的各个阶段有所不同,以应对工厂遇到的不同老化过程。在这种情况下,维护将包括:维修、测试/检查、反应性修理、因使用、老化或状况而进行的预防性更换以及更新。对于新的反应堆设计,可以考虑全方位的防御选项,期望将运行寿命延长至比当前设计寿命规范更长的时间。通过将建模方法嵌入决策支持框架,将考虑不同的风险防御选项,以产生安全可靠的核电厂性能的成本效益选择。所产生的方法将通过应用于反应堆系统来证明。
