DNRS: Department for Remotely Controlled Complexes and Technologies



    Andrii Sadovnikov graduated from the National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute” in Technologies of mechanical engineering. He works in the Institute from 2004. Since 2019 he holds a position of the Head of the Department for Remotely Controlled Complexes and Technologies.

    Andrii Sadovnikov is a specialist in the design and construction of mechanisms, automated devices, remotely controlled systems, which are resistant to the negative effects of radiation. He was engaged in the development of remote systems for research at the “Shelter” facility, including sampling of lava-like fuel-containing materials (FCM) and radioactive aerosols, selection and containment of radioactive wastes (RW), participated in the creation of a remotely controlled unit for thermal physics studies of FCM clusters in destroyed premises of the 4th power unit of the ChNPP. He takes an active part in the international scientific and technical activities of the Institute. He directed the creation of number of conceptual developments of robotic technologies within the cooperation between the ISP NPP of the National Academy of Sciences of Ukraine and “Qingdao Xianchu energy development group ltd”.

    The Department of Remote Systems and Technologies is engaged in the development and production of prototypes of robotic aggregates and other unmanned technologies for carrying out works on the elimination of the consequences of the Chernobyl disaster. Specialists of the department adopted unique technical solutions that allowed their automated devices to perform their work stably and reliably in conditions of extremely high levels of ionizing radiation, some of them worked on the Shelter facility for more than 15 years.

     Areas of activity:
• development, testing and implementation of equipment, devices, mechanisms and software for work in the branch of nuclear energy, nuclear and radiation safety, ecology;
• making researches related to the attraction of radiation-resistant remotely controlled equipment;
• analysis of international experiences in the development and usage of remotely controlled devices in the fields of nuclear energy, nuclear and radiation safety and ecology.

    The results of the research areas:

   During the years of the department’s existence a number of designs have been made and prototypes of remotely controlled systems (RCS) have been created for the implementation to solve such issues, as:
• radiation exploration and monitoring;
• sampling of radioactive aerosols and solid radioactive wastes (RW);
• fragmentation of high-level fuel containing materials (FCM);
• solid RW containerization;
• application of dust suppressing solutions to the clusters of FCM;
• thermos-physical studies of FCM clusters.

    During the development of remote devices and aggregates, the team constantly faces the need of implementation of innovative and non-standard solutions to solve each individual technical problem. Here are some examples of these solutions that have been implemented in recent years:

• screw augers as drivers for mobile robotic complex for working in the trunk of horizontal wells;
• “Reflector” – structurally simple mechanical device that allows the use of conventional video cameras instead of expensive radio-resistant cameras in conditions of high levels of ionizing radiation in the environment;
• portable, cheap and safe solid RW fragmentators;
• ” Magnitohod” – the robot with magnetic wheels for moving on vertical metal surfaces;
• implementation of a telescopic lifting device, which ensures the rigidity of the position of executive body on overhead-type crane systems, and many other non-trivial solutions.

   Today, the department’s specialists play a key role in the creation of a new International NPP Decommissioning Academy jointly with experts from the partner company of the «Qingdao Xianchu energy development group ltd.».
Joint activity of the ISP NPP with the Chinese partner company began in 2015. One of the first and most promising directions of the future Academy’s activity was the development and production of remote technological complexes. For the parties of the cooperation, it was obvious, that the development of robotic equipment is needed for works related to the decommissioning of nuclear facilities.
Specialists of the department participate in the work related to the commissioning of «New Safe Confinement – Shelter Object (NSC-SO)».
Specialists of the department are involved in several directions of the international activity of the Institute, including interacting with specialists of European educational and scientific institutions, carry out design work within the cooperation of the Institute with NATO, and, on the basis of scientific results, present materials at international scientific and technical conferences.

    Also remotely controlled unit is used  for sampling lava-like FCM developed within the research “Development of measures to enhance nuclear, radiation and ecological safety of the Shelter and the New Safe Confinement.

Units were implemented at the Chornobyl Nuclear Power Plant.
