Abstract
During the GUINEVERE FP6 European project (2006–2011), the zero-power VENUS water moderated
reactor was modified into VENUS-F, a mock-up of a lead cooled fast spectrum system with solid
components that can be operated in both critical and subcritical mode. The Fast Reactor Experiments for
hybrid Applications (FREYA) FP7 project was launched in 2011 to support the designs of the MYRRHA
Accelerator Driven System (ADS) and the ALFRED Lead Fast Reactor (LFR). Three VENUS-F critical core
configurations, simulating the complex MYRRHA core design and one configuration devoted to the LFR
ALFRED core conditions were investigated in 2015. The MYRRHA related cores simulated step by step
design peculiarities like the BeO reflector and in pile sections. For all of these cores the fuel assemblies were
of a simple design consisting of 30% enriched metallic uranium, lead rodlets to simulate the coolant and Al2O3
rodlets to simulate the oxide fuel. Fission rate ratios of minor actinides such as Np-237, Am-241 as well as
Pu-239, Pu-240, Pu-242 and U-238 to U-235 were measured in these VENUS-F critical assemblies with small
fission chambers in specially designed locations, to determine the spectral indices in the different neutron
spectrum conditions. The measurements have been analyzed using advanced computational tools including
deterministic and stochastic codes and different nuclear data sets like JEFF-3.1, JEFF-3.2, ENDF/B7.1 and
JENDL-4.0. The analysis of the C/E discrepancies will help to improve the nuclear data in the specific energy
region of fast neutron reactor spectra.
