This paper presents a comparison between the dynamic performance of PSB and VVER 1000 steam generator models. PSB is a large-scale integral test facility which simulates the VVER-1000/320 reactor. Volume and power scale are 1:300. It has four loops and each SG consists of 34 helicoidally tubes connected by two headers named hot and cold collector respectively. The Relap 5 nodalisation for the VVER 1000 was developed and qualified at DIMNP of University of Pisa, refs. /1/ and /4/, and the secondary side performance was investigated in detail. The goal of the paper is to analyse similarities and differences in the thermal hydraulic behaviour of the reference steam generator and of the model. The same philosophy has been pursued in nodalising the two systems.

Abstract
This paper presents a comparison between the dynamic performance of PSB and VVER 1000 steam generator models. PSB is a large-scale integral test facility which simulates the VVER-1000/320 reactor. Volume and power scale are 1:300. It has four loops and each SG consists of 34 helicoidally tubes connected by two headers named hot and cold collector respectively. The Relap 5 nodalisation for the VVER 1000 was developed and qualified at DIMNP of University of Pisa, refs. /1/ and /4/, and the secondary side performance was investigated in detail. The goal of the paper is to analyse similarities and differences in the thermal hydraulic behaviour of the reference steam generator and of the model. The same philosophy has been pursued in nodalising the two systems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
