Development of Inspection and Repair Technology for Fast Reactors

- Inspection Technology by the Electromagnetic Acoustic Transducer (EMAT) -

Tsurusoken developed an inspection technology for early detection of defects in the welded parts of reactor vessels of sodium-cooled fast reactors.

Inspection Technology by the EMAT image

We determined the optimum magnet structure by confirming the magnetic flux density by experiments and simulations.

Continuously scanning with EMAT was able to display the measurement results of the sample in 3D and enabled us to visually confirm the defects.
