Transcription

1 Technical Meeting on Heat Transfer, Thermal-Hydraulics and System Design for Supercritical Water Cooled Reactors Hosted by the Government of the United Kingdom through the University of Sheffield Sheffield, United Kingdom August 2016 Ref. No.: I3-TM Information Sheet A. Background There has been great interest internationally in both developing and developed countries in the design of innovative supercritical water-cooled reactors (SCWRs). This interest arises from the high thermal efficiencies (43 48% in the proposed concepts) and the simplified primary system (once-through reactor and direct steam cycle) promised by the SCWR concept, which improves economic competitiveness. The SCWR is one of the six Generation IV nuclear energy system concepts, and it is the only water-cooled reactor (WCR) concept being developed within the framework of the Generation IV International Forum.

2 Page 2 One of the main advantages of the SCWR is that, as the system is an evolution of existing WCR technology, there is already extensive worldwide experience in the construction and operation of this type of reactor. In addition, there is also substantial experience in the construction and operation of supercritical fossil-fuelled power plants. The major challenges for the SCWR are to develop and verify viable core designs, to understand the heat transfer and thermal-hydraulics of supercritical pressure water in the reactor cores, and to develop materials for the fuel and core structure with an appropriate water chemistry strategy. These are important because the SCWR cores will operate under conditions exceeding current experience with WCRs, and the properties of supercritical pressure water are unique. In support of Member States efforts in the area of SCWRs, the International Atomic Energy Agency (IAEA) launched, in 2008, a coordinated research project (CRP) entitled Heat Transfer Behaviour and Thermohydraulics Code Testing for Supercritical Water Cooled Reactors. The CRP was successfully completed in September Information generated from that CRP was documented in an IAEA Technical Document (IAEA-TECDOC-1746) and numerous publications and reports. A database of thermal-hydraulics parameters of interest to SCWR development was compiled and is currently housed in the central server of the Nuclear Energy Agency (OECD/NEA). Despite the completion of the CRP, several collaborative initiatives continue among institutes that participated in the CRP. Most of these institutes have expressed their strong interest in, and support for, initiating a new CRP on the thermal-hydraulics of SCWRs to continue the momentum of international collaboration. Accordingly, the IAEA launched, in October 2014, a new CRP entitled Understanding and Prediction of Thermal-Hydraulics Phenomena Relevant to SCWRs. The objective of this new CRP is to improve the understanding and prediction accuracy of thermalhydraulics phenomena relevant to SCWRs and to benchmark numerical toolsets for their analyses. The identified scope of collaboration is considered to cover applied research and development (R&D), as compared to the basis R&D carried out under the earlier CRP. In view of this, and as a complement to current IAEA efforts in the area of thermal-hydraulics of supercritical fluids, Member States have expressed an interest in organizing a Technical Meeting at which specialists in the areas of system design and thermal-hydraulics for SCWRs would have the opportunity of participating in extended technical discussions on the details associated with the science, technology and engineering of SCWRs. This Technical Meeting is the second one on the topic of heat transfer, thermal hydraulics and system design for SCWRs. The first one, hosted by the University of Pisa, was held in Pisa, Italy, from 5 to 8 July The second meeting will be hosted by the University of Sheffield and will take place in Sheffield, United Kingdom, from 22 to 24 August Representatives of the broad international research community are invited to participate. B. Objectives The purpose of the meeting is to provide a platform for detailed presentations and technical discussions on recent progress in R&D activities related to SCWRs, leading to the exchange of results and fostering worldwide collaboration in further R&D activities. A further goal of the meeting is to review and update the status of scientific and engineering related knowledge underlying SCWR concepts.

3 Page 3 The meeting will have the following main objectives, with an emphasis on application and design issues: To review and discuss progress in the development of experimental correlations, theoretical equations and numerical methods to describe the thermal-hydraulics behaviour of fluids under supercritical pressure conditions; To evaluate comparisons of analyses and numerical predictions of thermal hydraulics codes against theoretical estimates and experimental data for supercritical pressure fluids; and To review the current status of SCWR concepts and their core design, system design and approach to safety. As usual in this type of meeting, the programme will include a discussion session to enable participants to contribute to the summary and highlights of the meeting and to make recommendations to the IAEA on future activities in this field. C. Topics Papers are invited on all aspects of heat transfer, thermal-hydraulics and system design for SCWRs. Experimental and theoretical/modelling studies will be considered. The following topics have been identified as being of particular interest: Heat transfer, pressure drop, thermal hydraulics and thermodynamics for SCWRs; Critical flow during blowdown from supercritical pressures; Natural circulation and flow stability issues for SCWRs; Core design and neutronics for SCWRs; and Design of safety system and related aspects for SCWRs.
