“…Figure 17 illustrates that the Gnielinski and the Petukhov-Popov correlations clearly overestimate and both Dittus-Boelter correlations underestimate the heat transfer coefficient. Except from the entrance of the channel the Sieder-Tate correlation slightly over-predict and under-predict h. Currently in thermal-hydraulic modeling of the JHR, see (Pegonen et al, 2014a), the Dittus-Boelter correlation is utilized for conservative estimation of h. In light of the present results modified Dittus-Boelter would give a less conservative results and the correlation could be improved when taken into account entrance effect as it is done in Gnielinski correlations. Nevertheless there is an additional project that investigates the improvement possibilities to find a new more reliable correlation.…”

“…• The CEA 36 assembly JHR core reference power is 108.77 MW (Pegonen et al, 2014a), from which 5.145 MW is the total power of the hot fuel element and 0.264 MW is the power in the water, in the hot channel, originating from neutron moderation and gamma heating. In here it is assumed that the hot assembly and the water in it have the power with the factor 1.79 compared to the mean values.…”

“…In every simulation a reference pressure is adjusted to have an area-averaged pressure 600939 Pa at z= 0.7 m. Pressure value is obtained from the system code CATHARE simulation, described in Pegonen et al (2014a), where the full JHR with the simplified approach for the core is calculated.…”

“…The JHR unique design and the current thermalhydraulic modeling methodology is described in Pegonen et al (2014a). The CEA (Alternative and Atomic Energy Commission) methodology is used to analyze the thermal-hydraulic calculation of the reactor during the loss of flow accident and the future improvement possibilities are listed.…”

The newest European high performance material testing reactor, the Jules Horowitz Reactor, will support existing and future nuclear reactor designs. The reactor is under construction at CEA Cadarache research center in France and is expected to start operation at the end of this decade. This paper presents the Computational Fluid Dynamics simulation of the reactors hot fuel element. Moreover conjugate heat transfer analysis is performed for the hot channel. The main objective of this work is to improve the thermal-hydraulic knowledge of the complex hot fuel element and to present the most prominent finds. Possible improvements for the future work are suggested.
