Pools for the long term storage of spent nuclear fuel are extremely dangerous buildings. Their seismic resistance is very important and topical theme. Design feature of such structures is the presence of a rigid bottom and flexible frame top, which is most vulnerable to earthquakes.

The article considers the influence of various factors on the intensity of the vibrations of flexible frame top оf VVER-1000 spent nuclear fuel repository during earthquake. These factors are: soil stiffness, frequency composition of the initial impact and functioning capacity of repository.
