Accurate Determination and Benchmarking of Radiation Field Parameters, Relevant for Pressure Vessel Monitoring—Review of Some REDOS Project Results

CODEN: JAIOAD

Abstract

Plant life management needs a reliable estimation of radiation field parameters, including their uncertainty, to avoid the use of conservative approaches. The particular objectives of the REDOS project [1] are the improvements of the RPV monitoring, the improvement of the neutron-gamma calculation methodologies through the LR-0 engineering benchmarks for WWER-1000 and WWER-440, and the accurate determination of radiation field parameters in the vicinity and over the thickness of the RPV. This paper is mainly devoted to the comparison and analysis of the experimental and calculated LR-0 data. The LR-0 benchmark data consist of neutron spectra (WWER-440 Mock-ups) and neutron + photon spectra (WWER-1000 Mock-up) in several points from the barrel simulator to the outer surface of RPV and evaluated integral fluxes, space-energy indices, like the spectral indices and attenuation factors in measuring points.
