TOMSK, Feb 10 –
RIA Tomsk. The technology of ultrasonic
tomography for diagnostics of welded seams, developed by scientists of the TPU
School of Non-Destructive Testing & Security (TPU SNTS), was included in
the register of innovative solutions of Rosatom, which the state corporation
uses at its facilities, the press service of the university said on Wednesday.
According to the
press service, the register of innovative solutions of the Rosatom State
Corporation is a pool of developments with successful examples of
implementation at nuclear power facilities or in industry. Before application,
each development undergoes a multi-stage thorough examination. Technologies at
the stage of high availability, ready for replication, are included in the
register.
"Rosatom's
experts have included in the register of innovative solutions for the state
corporation the development of TPU non-destructive testing specialists.
Ultrasonic tomography technology for diagnosing welded joints allows to
effectively detect the smallest defects in the seams on complex parts used in
the nuclear industry", – is said in the report.
The method
assumes that the ultrasonic waves emitted by the transducer pass through a
material or object and interact with its internal structure. By the changes in
ultrasonic waves reflected from the structure, specialists can judge the
presence of hidden defects in the material and their characteristics. TPU
engineers robotized the process and applied know-how, making control more
sensitive and faster.

"We
combined our many years of experience and demonstrated the technology that has
already been used in the creation of a number of installations. For example,
the largest robotic ultrasonic tomograph in Russia for the details of the first
wall of the ITER thermonuclear reactor... Implementation examples have
confirmed that the technology gives an increase in control speed and
sensitivity", – Director of the TPU Engineering School of Non-Destructive
Testing Dmitry Sednev is quoted.
He noted that
this is the first development of TPU SNTS included in the register of
innovative solutions of Rosatom.
Earlier it was
reported that in November 2020 TPU entered the project to create a robotic
ultrasonic system for checking the quality of parts of the world's first
thermonuclear reactor, which is being built in the south of France within the
framework of the ITER international project. The device being developed will
allow the quality of welds on the parts of the object to be monitored.
