“…The full-scale (in the radial direction) models (mock-ups) of VVER-440 and VVER-1000 reactors were developed and investigated on LR-0 jointly by Nuclear Research InstituteŘež (Czech Republic), Škoda Nuclear Machinery Plzen (Czech Republic), and NRC Kurchatov Institute (Russia), see e.g. [2] and [3]. The top view on the VVER-1000 mock-up is presented in Fig.…”

Abstract.A set of benchmark experiments was carried out in the full scale VVER-1000 mock-up on the reactor LR-0 in order to validate neutron transport calculation methodologies and to perform the optimization of the shape and locations of neutron flux operation monitors channels inside the shielding of the new VVER-1000 type reactors. Compared with previous experiments on the VVER-1000 mock-up on the reactor LR-0, the fast neutron spectra were measured in the extended neutron energy interval (0.1-10 MeV) and new calculations were carried out with the MCNPX code using various nuclear data libraries (ENDF/B VII.0, JEFF 3.1, JENDL 3.3, JENDL 4, ROSFOND 2009, and CENDL 3.1). Measurements and calculations were carried out at different points in the mock-up. The calculation and experimental data are compared.

The fission rates measurements were carried out with track detectors in the WWER-1000 mock-up assembled in the experimental reactor LR-0. The 238U and 236U isotopes with the fission energy thresholds approximately 1.5 MeV and 0.8 MeV, respectively, were used. The tracks were counted by means of a photomicroscope with a digital camera controlled by a PC with corresponding software. The fission rate ratio of 236U and 238U has been evaluated in different measuring points as well as the fast neutron fluxes attenuation factors. The correction for photo fission has been included. The results obtained with different techniques were compared: the fast flux above 0.5 MeV was measured absolutely with a stilbene detector.
