OECD Benchmark for Uncertainty Analysis in Best-Estimate Modelling (UAM) for Design, Operation
and Safety Analysis of LWRs – Eleventh Workshop (UAM-11)
Erlangen, Germany
May 10 – May 12, 2017
Hosted by
AREVA NP GmbH
The OECD/NEA LWR UAM-11 workshop will be held in conjunction with other meetings (in the same week),
in order to facilitate co-ordination and sharing of work. The meetings concerned are:
- May 8-9, 2017 – Third OECD/NEA Sodium Fast Reactor (SFR) Uncertainty Analysis in Modelling (UAM)
benchmark workshop (SFR-UAM-3);
- May 8-9, 2017 - Fourth COBRA-TF (CTF) User’s Group (UG) Meeting (CTF-4);
- May 10-12, 2017 – Eleventh OECD/NEA Light Water Reactor (LWR) Uncertainty Analysis in Modelling
(UAM) benchmark workshop (LWR-UAM-11);
- May 10 – May 11 (morning), 2017– AER Working Group D meeting (VVER dynamics and safety);
- May 11(afternoon) – May 12, 2017 - Second OECD/NEA C5G7 Time-Dependent (TD) Neutron Transport
benchmark workshop (C5G7-TD-2).
A common registration webpage will be made available for the participants of SFR-UAM-3, CTF-4, LWR-UAM11, AER-D, and C5G7-TD-2 workshops by the OECD/NEA.
OECD/NEA UAM-LWR Benchmark is a benchmark for uncertainty analysis in best-estimate coupled code
calculations for design, operation, and safety analysis of
LWRs. Reference systems and scenarios for coupled code
analysis are defined to study the uncertainty effects for all
stages of the system calculations. Uncertainty
propagation is being estimated through the whole
simulation process – the benchmark builds a unified
framework, which can be used and followed in the future.
The chain of uncertainty propagation from basic data, and
engineering uncertainties, across different scales (multiscale), and physics phenomena (multi-physics) is tested
on a number of benchmark exercises for which
experimental data is available and for which the power
plant details have been released. These exercises are
organized in three (3) Phases – see the Figure above. For more information please visit https://www.oecdnea.org/science/wprs/egrsltb/UAM/. Separate specifications are being prepared for each Phase in order to allow
participation in the full Phase or only in a subset of exercises. The intention is to follow the calculation scheme
for coupled calculations for LWR design and safety analysis established in the nuclear power generation industry
and regulation. If you are interested to participate in the OECD/NEA UAM-LWR Benchmark please contact one
of the Benchmark Coordinators: Maria Avramova ([email protected]); Eric Royer ([email protected]);
and Kostadin Ivanov ([email protected]).
The LWR-UAM-11 workshop will involve all interested participants with objective to discuss in depth the
specifications for different phases, support data, benchmark exercises and test cases, obtained results from the
participants, methodologies for multi-physics verification & validation and sensitivity & uncertainty analysis, and
applications to LWR cores and systems.
