CCP for nuclear thermal hydraulics - supporting next generation civil nuclear reactors (CCP NTH)

核能是一种二氧化碳中性的能源发电技术，将在减少温室气体排放、实现政府和社会目标、提高生活质量方面发挥重要作用。然而，核能的一个主要问题是它的安全性。正在开发的下一代核反应堆将在未来几十年内部署，其目标是利用被动冷却等技术实现固有安全。这种系统需要非常先进的热工液压方法来处理更高温度和压力的系统和/或非常规冷却剂，如液态金属和熔盐。传统的方法已不足以应对即将面临的新挑战。拟议的核热工水力学CCP旨在建立和支持一个研究人员和工程师社区，以开发和维护计算方法和软件包，使核热工水力学工具现代化，以满足先进的下一代核反应堆系统发展的要求。拟议的方案协调会的活动分为两个工作包。WP1旨在通过各种活动和活动建立社区和网络。这些活动包括年度技术会议、专题、跨ccp和国际研讨会、培训课程、国际和英国访问/交流计划、基准测试练习和各种外展活动。WP2旨在通过STFC的研究社区计算科学中心提供的服务，为社区开发和维护方法和计算机代码。该工作包括支持、开发和维护(i)用于分析反应堆系统的稳健（可靠、负担得起且用户友好）CFD方法和工具，以及（ii）高保真建模和仿真方法和软件工具，重点关注社区DNS代码，旨在为建模验证和工程相关开发提供新的理解和基准数据库。CCP还将探索创新和颠覆性的方法，旨在带来计算热工分析的阶梯式变化。拟议的CCP由学术界和工业界的合作伙伴组成。最初的学术会员包括曼彻斯特大学、谢菲尔德大学、利兹大学、利物浦约翰摩尔大学、剑桥大学、牛津大学、班戈大学、玛丽女王大学、帝国同事伦敦大学和STFC达斯伯里实验室。工业合作伙伴是EDF能源、弗雷泽-纳什咨询公司、Moltex、劳斯莱斯和Wood Nuclear。CCP还包括来自宾夕法尼亚州立大学/阿贡国家实验室的国际合作伙伴和顾问。中国共产党将鼓励任何感兴趣的研究人员和工程师在它成立和运行后成为会员，中国共产党组织的任何活动都对整个社区开放。

Nuclear energy is a CO2 neutral energy generation technology and will play an important role in reducing green-house gas emissions to meet government and societal targets and improve the quality of life. However, a main concern of the nuclear energy is its safety. The next generation nuclear reactors under development to be deployed in the next decades are aimed at achieving inherent safety using technologies such as passive cooling. Such systems require a significantly advanced thermal hydraulics approach to deal with much higher temperature and pressure systems and/or non-conventional coolants such as liquid metal and molten salts. The traditional methodology is insufficient to deal with the new challenges to be encountered. The proposed CCP for nuclear thermal hydraulics is aimed at building and supporting a community of researchers and engineers for developing and maintaining computational methods and software packages to modernise the nuclear thermal hydraulics tools to meet the demands imposed from the development of advanced next-generation nuclear reactor systems. The activities of the proposed CCP are grouped into two work packages. WP1 is aimed at community building and networking through a variety of activities and events. These include annual technical meetings, special topic, cross-CCP and international workshops, training courses, international and UK visit/exchange programs, benchmarking exercises and various outreach activities. WP2 is aimed at development and maintenance of methodology and computer code for the community through services provided by STFC's Computational Science Centre for Research Communities. The work includes supporting, developing and maintaining (i) robust (reliable, affordable and user-friendly) CFD methodologies and tools for the analysis of reactor systems and (ii) high fidelity modelling and simulation methods and software tools, focusing on a community DNS code, aimed at providing new understanding and benchmarking database for modelling validation and engineering correlation development. The CCP will also explore innovative and disruptive methodologies aimed at bringing a step-change in computational thermal hydraulics analysis. The proposed CCP is formed from academic and industrial partners. The initial academic memberships are Universities of Manchester, Sheffield, Leeds, Liverpool John Moores, Cambridge, Oxford, Bangor, Queen Mary, Imperial Colleague London and STFC Daresbury Laboratory. The industrial partners are EDF Energy, Frazer-Nash Consultancy, Moltex, Rolls-Royce and Wood Nuclear. The CCP also includes an international partner and advisor from Penn State University/Argonne National Laboratory. The CCP will encourage any interested researchers and engineers to become a member when it is up and running and any activities organised by the CCP are open to the entire community.
