Rod Bundle Heat Transfer Facility

(RBHT-II) Project - Benchmark

Welcome to the Website devoted to

RBHT Benchmark

The OECD/NEA RBHT-II (Rod Bundle Heat Transfer) Project is an International three-year NEA Joint Project whose objective is to conduct new experiments and evaluate system hydraulics and sub-channel codes in the simulation of reflood tests. Such tests are performed in a full height rod bundle facility equipped with advanced instrumentations capable to measure the real-time droplet field and the steam temperatures and velocities.

Within the RBHT-II project a challenging benchmark exercise is conducted, including an open and a blind test phase providing a unique opportunity to project’s participants to apply uncertainty methods as part of the code assessment process. The test matrix encompasses both steady and oscillatory reflood inlet flow conditions, all of which are data that have never been obtained before.

This website is intended as a supporting tool for the different organizations that participate to the RBHT-II analytical benchmark. The aim of the website is to collect the project participants’ submissions, to distribute the project documentation, and to facilitate the management of the benchmark.
