RA2: NDE qualification and development of manipulators for testing nuclear reactors

Work in this research activity focuses on non-destructive testing of metallic materials and building concrete. Our goal is to cover a wide range of research and development in the field of non-destructive testing. The list of our activities includes various methods of testing, such as ultrasonic phased array method or laser profilometry, developing custom robotic manipulators, the development of experimental apparatus for measuring, testing development methodologies, inserting weld defects and more.

Our activities are focused on the energy industry, especially for components and piping systems of nuclear power plants in the Czech Republic and abroad. These activities are important in order to ensure the safe operation of power equipment, economy and life extension.

Non-destructive testing of metallic materials

Laboratory of non-destructive testing of metallic materials is engaged in developing new procedures for non-destructive testing of ferritic, austenitic and heterogeneous welded joints and components of complex configurations. In addition to the classical method used ultrasound phased array with a single, double and matrix probes. They enable a wide range of settings to get the best detection and sizing discontinuities. The procedures for both manual and mechanized testing are verified using specimens with embedded artificial discontinuities and simulations in specialized software.

NDE laboratory is equipped with modern equipment for ultrasonic testing and more common facilities for testing of metallic materials, other methods such as laser profilometry, visual and capillary, etc.

It deals with the development of nonlinear ultrasonic methods for testing concrete. Qualifications previously known and used by non-destructive methods for testing concrete samples irradiated. The motivation is to find a method to determine the degree of violation of the concrete structure due to the radiation for long-term operational reliability and service life of nuclear power plants. Non-destructive testing of concrete addresses, inter alia, a number of specific issues with using irradiated material. In severe accidents, the quality of concrete fundamentally decide on the consequences of the accident, so research in this area is necessary.

Laboratory for NDE of concrete develops and uses advanced electro-acoustic instruments with digital processing of the measured signal. It uses the latest software to ensure transparent outputs with the vivid capture of defects in concrete.
