| description | This paper presents the results of the analysis of the Unprotected Loss of Flow (ULOF) experiment SHRT-45R performed in the EBR-II
fast reactor. These experiments are being analyzed in the scope of a benchmark exercise coordinated by the IAEA. The SHRT-45R
benchmark contains a neutronic and a thermal-hydraulic part and results are presented for both. Neutronic calculations are performed with
the ERANOS2.0 code in combination with various sets of nuclear data. The thermal-hydraulic evaluation is done with RELAP5-3D. The
results are that the major neutronic parameters are well predicted with error margins on the order of 1%. The thermal-hydraulic results are
less favourable: a consistent overestimation of the outlet temperature occurs in combination with erroneous flow distribution. Observed
differences with measured data cannot be explained easily. The work presented in this paper was undertaken to investigate and validate the
effectiveness of the calculational tools and data that are commonly used in our lab for the design and analysis of liquid metal cooled fast
reactors. |
