The main factors affecting the elements of the heat exchanger of the spent fuel pool cooling system during operation are considered. The analysis of design, technical and operational documentation is carried out for the purpose of preliminary assessment of the technical condition of the heat exchange equipment of nuclear power plants. The data on the installed capacity and service life of power units of the Ukrainian NPPs are given.

The aim of the work is to determine the possibility of using local seismological networks of nuclear power plants as elements of the seismological monitoring system of the territory of Ukraine.

The basic directions of the Action Plan to assess seismic hazard and seismic check of existing nuclear power plants, approved SNRCU and NNEGC "Energoatom", which is the basis for work on seismic monitoring systems of nuclear power plant in Ukraine are represented. The experience of expert of IGPH NAS in this field is explined. The basic principles, their aims and objectives are explined too. The spesification for the Rivne NPP is represented as an example. The situation for each of NPP is outlined for short term.

Purpose. The aim of study is to create the method of seismic wave fields modeling for a broad class of vertically and horizontally inhomogeneous layered media. Simulation will make it possible to more precisely assess the characteristics of sedimentary strata in the study of the transmission characteristics of the environment under the engineering structures. Methodology. At modeling in engineering seismology should be used a wide frequency range (from 0 to 200 Hz) to study all possible effects on engineering structures.
