This paper describes the analysis which was done to qualify the nodalisation for the Counterpart Test (CT) performed in the PSB test facility. PSB is a large-scale integral test facility installed in Russia. It models aVVER-1000 reactor (project V-320), with volume and power scale of 1:300. The concerned CT, which is a small break loss of coolant accident (SBLOCA), has been performed in LOBI, SPES, BETHSY and LSTF that simulate PWR. The goal of this paper, which is to demonstrate the nodalisation qualification adopted for the CT analysis, was achieved by showing that the experiment UP 11% break, also performed in PSB facility, could be reproduced, and the errors were found to be within the limits set by the Fast Fourier Transform Based Method (FFTBM).

Abstract
This paper describes the analysis which was done to qualify the nodalisation for the Counterpart Test (CT) performed in the PSB test facility. PSB is a large-scale integral test facility installed in Russia. It models aVVER-1000 reactor (project V-320), with volume and power scale of 1:300. The concerned CT, which is a small break loss of coolant accident (SBLOCA), has been performed in LOBI, SPES, BETHSY and LSTF that simulate PWR. The goal of this paper, which is to demonstrate the nodalisation qualification adopted for the CT analysis, was achieved by showing that the experiment UP 11% break, also performed in PSB facility, could be reproduced, and the errors were found to be within the limits set by the Fast Fourier Transform Based Method (FFTBM).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
