OECD Nuclear Energy Agency (NEA), McMaster University, CANDU Owners Group (COG)
Building on the OECD-NEA BFBT and PSBT benchmarks, McMaster University, in collaboration with North Carolina State University, has launched a CANDU thermalhydraulic benchmark under the WPRS Expert Group on Uncertainty Analysis in Modelling. CANDU Owners Group (COG) had provided full-scale experimental data for a 28-element CANDU fuel assembly including pressure drop and detailed pin temperatures for single-phase and boiling conditions.
The purpose of this benchmark is to:
Reference systems and scenarios
A unique aspect of these data are the traversing thermocouples which provide axial and azimuthal sheath temperatures along every fuel element for both pre and post-CHF conditions. A wide range of test conditions (inlet pressure, mass flows and inlet temperatures) will be provided to the participants along with the temperature scans, CHF location and power, and post-dryout sheath temperatures. Similar to the BFBT and PSBT benchmarks, the complete set of data will be made available to participants after completion of the benchmark.
Phase I: Pre-CHF Benchmark
Phase II: CHF Benchmark
Coordinator: D.R.Novog (firstname.lastname@example.org)
The Second meeting will be held in conjunction with UAM-14
The first meeting was held in conjunction with UAM-13
The benchmark proposal was accepted at the 2018 WPRS-EGUAM meeting and a kickoff meeting was held in conjunction with UAM-12.
