Proposal

Dr. Charles Moulinec and Dr. Wei Wang of STFC's Computational Engineering Group together with Co-investigators Prof. He and Dr. Liu (University of Sheffield) and collaborator Dr. Uribe (EDF), have been successful with the ARCHER2 Pioneer proposal '"High-Fidelity Simulations to Improve Performance and Safety of PWRs".

They have secured substantial amounts of time (300,000 node hours) on the UK's new flagship supercomputer that enables them to explore conditions inside a pressurised water (nuclear) reactor (PWR).

The researchers will explore high-definition simulations of the flow of large eddies of water combined with heat transfer in the PWR fuel assembly under conditions known as 'clad ballooning', i.e. swelling of some assembly tubes. This phenomenon impairs coolability of the fuel assembly, heat transfer and the removal of the decay heat of the fuels.

Thanks to their successful proposal, this team will keep the Collaborative Computational Project Nuclear Thermal Hydraulics (CCP-NTH) at the forefront of High Performance Computing research into PWRs.


Publication

Prof. Paul Durham, the Former Director of Department (STFC) and President of CECAM (Centre Europeén CCP5_Summer_School_2009.PNGde Calcul Atomique et Moléculaire) together with fellow authors (Profs. William Smith, Martyn Guest and Ilian Todorov –all STFC) published  a short history of the CCPs in the UK, exploring the connections to CECAM, the effect on UK's HPC endeavours and on Computational Science and Engineering research, with CCP5 (Computer Simulation of Condensed Phases) as the example of one of the long-standing and thriving communities.
The article 'Molecular simulation and the collaborative computational projects​' tells the story of molecular simulation in the UK, with CCP5 itself at centre stage, using the written records in the CCP archives.

Change of Chair

the CCP Steering Panel. Members of CoSeC and the CCP Steering Panel would like thank Adrian for being an enthusiastic, supportive and effective chairperson over this period. Professor Mark Savill (Cranfield University and pictured ​right), Project Chair of CCPEngSci (Software Developments to support the Engineering Community) is warmly welcomed and thanked for agreeing to take on this role.
