THE TECHNOLOGY READINESS ASSESSMENT OF NUCLEAR POWER SYSTEM IN FNPP BASED ON THE INTEGRATION OF DELPHI AND AHP METHOD

抄録

In the recent several years, as the growing demand for energy supply in offshore areas, there is increasing interest in the Floating Nuclear Power Plant (FNPP) mounted on the movable marine platform and would be deployed worldwide. The concept design of OFNP-300/OFNP-100 has been promoted at Massachusetts Institute of Technology, and the Akademik Lomonosov FNPP is ready for operation in Russia. Land-based nuclear power technology has gradually turned to be mature through half a century of development. Nevertheless, it's important to pay attention to the environmental adaptability, the systematic integrity and the equipment reliability in FNPP because of the compact structure, strong maneuverability and lack of support. To reduce the risk in the research and development processing, technology readiness assessment (TRA) is a necessary process to select the best technologies meeting the system requirements by examining maturity of the technology. However, the general method of the TRA only applies to single key technology, it is difficult to assess the integrity readiness and system readiness of nuclear power system in FNPP. In this paper, the method of the TRA based on the integration of Delphi and AHP method be adopted to solve these problems. Using the method developed, the multi-hierarchy key technology system, the assessment model and the assessment process were built. In addition, the low-hierarchy single technology readiness levels, the mid-hierarchy integrity readiness levels and the high - hierarchy system readiness levels of nuclear power system in FNPP were assessed. The result shows that the assessment levels of the single technology readiness of nuclear power system are generally high. Moreover, the assessment levels of the integrity readiness and system readiness of nuclear power system in FNPP are relatively low. As a result, it’s necessary to pay attention to the integrity between the technologies and systems in follow-up research and development process. Furthermore, the method developed are not only be used to assess the TRA of nuclear power system in FNPP, but also can be applied in other complex engineering management field..
