Modelling of nuclear fuel assemblies vibration in mutual interaction

Popis výsledku v původním jazyce

The coolant pressure pulsations generated by the main circulation pumps in the coolant loops are one of the main sources of reactor excitation [1]. The vibrations of the VVER 1000-type re- actor and its components caused by the coolant pressure pulsations was investigated in previous authors’ research works on a linearized model of the reactor [2]. This model was later modified by the effect of the friction-vibration interactions in the reactor core barrel (CB) couplings with clearances [4]. The fuel assemblies (FAs) vibration without mutual interaction respecting new knowledge about excitation by coolant pressure pulsation measured at NPP Temel ́ın [3] was published in [5]. The aim of the paper is to present an approach to the modelling of chosen FA vibration inside the reactor core with the possibility of interaction with the surrounding FAs.
