FLUOLE-2: An Experiment for PWR Pressure Vessel Surveillance
Abstract : FLUOLE-2 is a benchmark-type experiment dedicated to 900 and 1450MWe
PWR vessels surveillance dosimetry. This two-year program started in 2014 and will end in
2015. It will provide precise experimental data for the validation of the neutron spectrum
propagation calculation from core to vessel. It is composed of a square core surrounded by
a stainless steel baffle and internals: PWR barrel is simulated by steel structures leading to
different steel-water slides; two steel components stand for a surveillance capsule holder
and for a part of the pressure vessel. Measurement locations are available on the whole
experimental structure. The experimental knowledge of core sources will be obtained by
integral gamma scanning measurements directly on fuel pins. Reaction rates measured
by calibrated fission chambers and a large set of dosimeters will give information on the
neutron energy and spatial distributions. Due to the low level neutron flux of EOLE ZPR
a special, high efficiency, calibrated gamma spectrometry device will be used for some
dosimeters, allowing to measure an activity as low as 7. 10−2 Bq per sample. 103mRh
activities will be measured on an absolute calibrated X spectrometry device. FLUOLE-2
experiment goal is to usefully complete the current experimental benchmarks database used
for the validation of neutron calculation codes. This two-year program completes the initial
FLUOLE program held in 2006–2007 in a geometry representative of 1300MWe PWR.
