Results of scientific activity:
Complex of works is performed on power generating units of NPS of Ukraine:
- Equipment for templates cutting out from reactor vessel is developed and tested on SU NPS;
- On the base of complex investigation with the use of modern methods and equipment we have proposed mechanism of failure of welded joints # 111;
- Data base of vortex current control of steam generator pipe still is produced (more than 1,1 mln of measurements), algorithm of annual control planning is proposed;
- Methodology of defect type determination is proposed by data of VTK;
- Obtained results are used on extension of designed operational life of nuclear generating units and on construction of new power units on the base of WWER-1000.
