CCP for nuclear thermal hydraulics - supporting next generation civil nuclear reactors (CCP NTH)
Lead Research Organisation:
University of Sheffield
Department Name: Mechanical Engineering
Abstract
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.

Planned Impact
The activities and outputs of the CCP will have significant impact on the society, economy, people (training) and knowledge generation. Fundamentally, the participation and enthusiastic support of the industrial partners will naturally form a direct route to impact, while many of the CCP activities are themselves essential pathways to impact.
The purpose of the proposed CCP is to develop and maintain advanced tools for the development of next-generation inherently safe nuclear reactor systems, and the success of the proposed CCP will directly contribute to improving the quality of life. Specific activities have been included in the proposed CCP to enhance and speed up the impact on the society. We have planned to use a variety of outreach activities to reach out the public. These include making use of the open days and public lectures organised by STFC and universities. We will also create a non-expert section on the CCP website explaining the next generation systems. Additionally, the CCP will use their collective expertise to positively influence the technology and investment policies through inviting representatives from BEIS, EPSRC and Office of Nuclear Regulation (ONR) to participate in our meetings. Such influences will also be achieved through memberships of government policy advisory committees, e.g., Hector Iacovides and Eugene Shwageraus are members of Nuclear Innovation and Research Advisory Board.
The government has an ambition to establish the UK as a significant partner in the global deployment of advanced nuclear reactor technologies. Thanks to the close involvement of the UK nuclear industry, the outputs generated from the proposed CCP will surely and effectively be transferred to the industry to bring commercial benefit to the UK economy. Industry outreach days will be organised to deepen industry involvement. The industry partners will directly influence the choice of the benchmarking cases and work by the CoSeC ensuring the industry's current and long term commercial needs met. Additionally, all the Investigators and many other members of the Working Group have worked extensively with the nuclear industry through research projects, PhD supervision and consultancy, which will provide an effective route for the outputs of the proposed CCP to be transferred to the industry.
Many of the activities will contribute to maintaining technical knowledge and people in computational thermal hydraulics in the UK, which is a huge challenge to meet the demands from the new builds of nuclear reactors and future development. In particular, some activities are designed to attracting new graduates to join this profession and providing them with good training opportunities. Examples include training courses, prizes for best presentations at technical meetings, and encouragement for PhDs to participate in benchmarking. The Working Group includes early career researcher (ECR) members who will be encouraged to organise networking activities among themselves.
Alongside the development of software codes, activities organised by the proposed CCP and the collaborations within the community are expected to also lead to the creation of new knowledge in areas of modelling methodologies, numerical methods and the understanding of the thermal hydraulics physics. Such new knowledge will be effectively recorded and disseminated through a number of means, including, annual technical meetings, the CCP website and publications in journals. Benchmarking exercises to be organised will particularly contribute to the generation of knowledge on the suitability of computer codes, physical models and numerical methods on typical problems encountered in nuclear systems. Cross CCP workshops will be organised to facilitate new knowledge generation and transfer.

Title | Release of the CCP-NTH community DNS code CHAPSim1 |
Description | The community code, CHAPSim, was used by several research groups and there were both many repeated code sections and particular codes meeting different needs. When CCP-NTH started in April 2020, we collected different version of CHAPSim from those research groups. We filtered repeated functions, made unique function universally useable for different applications, reformatted the code with a standard Fortran 95 format, created a user-friendly input/output interface, added some python scripts for basic data plotting and visualisation and added comment section and variable description sections to generate a user-friendly and readable Doxygen file. To enrich the application of CHAPSim1.0, we added subroutines/functions to enable the code to deal with numerical simulation of thermal-hydraulics of liquid metal (i.e. liquid sodium, liquid lead, liquid bismuth and liquid lead-bismuth eutectic), extending the application of the code from only supercritical fluids to liquid metal for thermal-hydraulics. After all the work done, a unified version of CHAPSim was launched in GitHub for existing users. This is called CHAPSim1.0. |

Impact | This work made a solid foundation for future code development and was required for effective user support in the long term. Now, most existing users of CHAPSim have moved to this launched CHAPSim1.0 for their research. A CHAPSim users' forum has been created in SLACK to promote communications between users and we also provide informal support for users' questions in this forum. Two users' meetings have been held to support users' application of CHAPSim to their research. The unified code and regular users' meetings will promote this CFD solver to more users and enhance the communication of users from different research institutes. |

Title | Release of the CCP-NTH community DNS code CHAPSim2 |
Description | CHAPSim2 is a highly scalable open source Computational Fluid Dynamics (CFD) software specifically developed for the nuclear thermal hydraulics community. It is a finite-difference-based incompressible solver that uses a pressure-correction method for direct numerical simulation (DNS) of single-phase flows with significant variable properties, such as fluids at supercritical conditions and liquid metals. The code supports both explicit and implicit spatial discretisation strategies. The explicit methods include 2nd and 4th order central difference schemes with a 3/5-cell stencil, while implicit compact schemes are available for 4th and 6th orders. The pressure is computed by solving a Poisson equation. It relies on a 3-D Fast Fourier Transform (FFT) algorithm that supports various types of boundary conditions and uses the 2decomp&fft library. CHAPSim2 relies on Message Passing Interface (MPI) for CPU distributed memory machines and has demonstrated very good performance on ARCHER2. |
Type Of Material | Improvements to research infrastructure |
Year Produced | 2022 |
Provided To Others? | Yes |
Impact | CHAPSim2 demonstrates excellent performance on ARCHER2 and run efficiently up to about 5% of the total machine size using a mesh over 1 billion cells. The launch of the CHAPSim2 to the CCP-NTH community marks one of our promised milestones for this project. |
