The FONESYS and SILENCE networks are run by some of the leading organizations
working in the nuclear sector, and work in a cooperative manner since about a decade having
one or two meetings per year.
The FONESYS members are developers of some of the major system thermal-hydraulic
codes adopted worldwide. FONESYS has been created to strengthen the current technology,
cooperate and share recent advances, identify and discuss further ways of improvements in
system thermal-hydraulic code development and their application especially for licensing
purposes and safety analyses.
On the other hand, SILENCE members own and operate important thermal-hydraulic
experimental facilities. SILENCE aimed at promoting: cooperation and knowledge transfer;
discussion on state-of-the-art technological issues; revival of interest in significant
experimental campaigns; support to organizations and countries embarking in large
experimental programs. SILENCE is also the promoter of SWINTH, an international workshop
on instrumentation and measurement techniques.
In this paper selected key achievements from the networks are presented and some
activities proposed to address the remaining issues in thermal-hydraulics are summarized
