説明
<p>In nuclear power plants, hydrogen accumulation inside the pressure transmitter causes sensor drift. By analyzing the drift factors, we found that the factors contributing to drift were radiolysis of silicone oil as well as hydrogen permeation. We proposed a drift suppression method using palladium, which is a hydrogen occluding material. The effects of suppressing drift were evaluated through hydrogen absorption experiments of palladium (Pd) in the silicone oil. The experimental results in an environment equivalent to 10 years of an actual plant indicated that the amount of drift in the pressure transmitter without Pd was +8.64kPa. Our method using Pd for the pressure transmitter showed that the amount of drift was below the detection limit (+0.01kPa).</p>
