system under seismic impact is determined by the risk of falling process
equipment and building structures on the overlap of storage compartments or
stored nuclear fuel. To increase the safety of building structures under
seismic impact, it is necessary to pay special attention to the design features
of the frame part and the interface between the monolithic storage compartment
and the frame part, as the most vulnerable link.

“Wet” spent nuclear fuel repositories represent a potential hazard to people and the environment, so their seismic stability is an important and urgent issue. Design feature of such buildings is the presence of rigid concrete bottom and flexible framed top, which is the most vulnerable to earthquakes.
This article describes the evaluation of the effectiveness of the damping devices to improve the seismic resistance of the flexible framed top of the existing «wet» storage facility of spent nuclear fuel of VVER-1000 reactors.

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.
