in the TALL-3D facility which was
­designed for validation of coupled
STH and CFD codes. Finally, data from
the NACIE-UP facility will focus on the
multi-scale coupling of the behavior
in the fuel assemblies and the loop
system.
8 Guidelines and education

project is the establishment of Best

Validation methodologies, and Uncertainty

this purpose work meetings have
been organized in Stockholm mid
2016 in which the current practices
and experiences of all partners and
some invited experts from outside the
project have been compared and
­discussed. This can be considered as a
first but important step towards a
set of recommendations to the nuclear
liquid metal thermal hydraulics
­modelling community.
With respect to education and
training, the following activities are
foreseen within the project:
• Lecture Series
A lecture series was organized in
April 2017 hosted by VKI in
­Belgium. During the lecture series,
experts from the project disseminated
their knowledge on
­experimental techniques and
­modelling approaches to a wide
range of students and young
­professionals (see Figure 8).
• Textbook
With the lecture series notes as a
firm basis, the material available
will be updated and elaborated to
compile a textbook which should
be issued near the end of the
­project early 2019.
• Code Training
Finally, code specific trainings are
foreseen as a part of the project.
9 Summary and outlook
The SESAME project on liquid metal
reactor thermal hydraulics started in
April 2015. The project uses well the
existing European infrastructure and
expands the existing infrastructure
where needed. First results of the
­experimental and numerical program
are being produced providing reference
data for necessary code development
and/or validation. Within the
coming years, the ambitious but
­realistic objectives of the project shall
be targeted, i.e.:
1) Development and validation of
­advanced numerical approaches
for the design and safety evaluation
of advanced reactors
2) Achievement of a new or extended
validation base by creation of new
reference data
3) Establishment of Best Practice
Guidelines, Verification & Validation
methodologies, and Uncertainty
Quantification methods
The third objective is a very important
one, as it was unanimously indicated
as a high priority topic by all system
designers during the project definition
phase. This is addressed
through a well defined series of
work meetings, lectures, and the
­compilation of a textbook.
