Project summary

The purpose of the project is the use of the results of studies in the field of high-coherence and nonlinear acoustics in the development of new methods and technical means for nondestructive testing of engineering structures, defectoscopy of amorphous and crystalline materials, which are the final products of the solidification of high-activity liquid waste, and for high-resolution engineering seismic prospecting.

The widely used defectoscopy methods based on the principles of linear acoustics have low sensitivity with respect to some defect types and usually allow us to perform only local diagnostics.

It is assumed that the studies performed will result in the development and wide implementation of principally new methods of diagnostics and nondestructive testing, which have several orders higher sensitivity and selectivity with respect to some defect types (cracks, cleavage, etc.) and can be used in the nondestructive testing of engineering structures (nuclear power plants, dams, bridges, pipelines, etc.) in order to improve their safety and operation reliability, as well as for defectoscopy of the products of the solidification of liquid radioactive wastes for disposal.

The new feature in the proposed method to be used in engineering seismic prospecting is use of high-coherence signals, which allow us to ensure long-duration coherent filtering of useful signals against the background of low noise level in the high-frequency range, possibility to control the space-time structure of the sounding fields and high space resolution. Such seismoacoustic sounding can provide checking of the stress regions in the earth’s rocks, reveal the fracturing regions and minerals, find the ruptures and karstic cavities, which is important for prediction of seismic activity and choosing the sites for construction of nuclear power plants, other hazardous objects, and places for disposal of radioactive wastes.

The priority of the Russian participants in the project in the above field is known worldwide. This is due to both the high level of theoretical studies in the field of coherent and nonlinear acoustics and large experience in the creation of special acoustic radiators: electromagnetic tone radiators (IAP RAS) and highly synchronized explosive sources (VNIIEF), as well as the experience of VNIINM in the field of development of technologies for solidification of liquid high-activity wastes.

The timely nature of the studies under this project is confirmed by the rapid growth of the number of publications and special discussions at international conferences. Similar studies are carried out in many world’s scientific centers, one of which is Los Alamos National Laboratory (LANL) whose scientific group headed by a specialist in the field of nonlinear acoustics and seismology, Dr. P.Johnson cooperates with the authors of this project, which can be the basis for long-term cooperation between IAP RAS, RFNC-VNIIEF, SRC-VNIINM, and LANL.

The participants of the project hope that the possibility of practical use of the methods developed will attract new partners.
