ナトリウム中目視検査装置の超音波センサの濡れ性のためにナトリウム濡れ性試験を実施し、250$$^{circ}$$Cでのさまざまな金属メッキ元素と液体ナトリウムの反応性濡れの調査を実施した。SUS304試験片は4種類の金属(ニッケル,パラジウム,金,インジウム)で電気メッキし、金属をメッキした試験片上のナトリウム液滴の拡がり速度を測定した。拡がり速度は、メッキの溶解度が大きくなるにつれ上昇した。それぞれのメッキした試験片の拡がり速度に関する定数$$alpha$$は、メッキ元素に対して一定であり、メッキ元素の溶解度の対数に比例した。これらから、われわれは溶解度に基づいてメッキ元素を選ぶことが可能であると考えた。

The sodium wetting experiments were performed to investigate the reactive wetting of metallic plating materials by liquid sodium at 250 $$^{circ}$$C for the ultrasonic sensor of the under-sodium viewer. SUS304 stainless steel specimens were electrolytically plated with four metallic materials (Nickel, Palladium, Gold and Indium) which have different solubility in sodium, and the spreading velocity of sodium droplets on the metallic plated specimens was measured. It was confirmed that the spreading velocity increased as the solubility increased, and the constant $$alpha$$ on the spreading velocity on the plated specimens was unique for the plating materials and was proportional to the logarithm of the solubility of the plating materials. Furthermore, it is considered possible to select plating materials based on solubility from the result of this study.
