CORROSION MONITORING SENSOR, CORROSION DEPTH CALCULATION SYSTEM, AND METAL CORROSION SPEED CALCULATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a corrosion monitoring sensor, a corrosion depth calculation system, and a metal corrosion sped calculation system capable of detecting very small corroded portion generated in a waste disposal container for radioactive waste, and continuously monitoring a measurement target in response to the temperature and pressure of a burial environment.;SOLUTION: A corrosion monitoring sensor 10 is a corrosion monitoring sensor for monitoring a corrosion depth state of a measuring target metal W buried in a ground G at a predetermined depth from a ground surface by electrochemical measurement using an action electrode 1, a counter electrode 2, and a reference electrode 3, the action electrode is a measuring target metal plate formed of the same metal material as the measuring target metal material, the counter electrode is a platinum plate, the reference electrode is a carbon plate or graphite plate, and the action electrode, the counter electrode, and the reference electrode are arranged to be buried in a heat resistant resin 4 so that plate surfaces of the action electrode, the counter electrode, and the reference electrode are exposed on the same plane underground.;COPYRIGHT: (C)2016,JPO&INPIT
