US 2024/0192123 A1 · IN-SITU CORROSION MONITORING DEVICE AND METHODS OF USE THEREOF

Abstract

A device for in-situ corrosion monitoring in a molten salt reactor system includes a mounting structure and a plurality of probes. Each probe of the plurality of probes may have a main portion and a thinned region that together define a sealed chamber with the mounting structure. Each thinned region of the plurality of probes may be configured to corrosively fail, when exposed to a corrosive environment, both: (i) before any main portion of the plurality of probes, and (ii) temporarily in series with the other thinned portions of the plurality of probes. The device may further include a plurality of sensing features corresponding to the plurality of probes, each sensing feature disposed in a respective sealed chamber of the plurality of probes. Each sensing feature may be configured to detect a breach of the respective sealed chamber caused by the corrosive failure of the thinned region.

3 more elements

A system for in-situ corrosion monitoring in a molten salt reactor system, the system comprising

a process barrier containing a molten salt composition;
an in-situ device at least partially in the molten salt composition, the in-situ device configured to indicate a time of corrosive failure for each of a plurality of thinned regions of the device, each thinned region of the plurality of thinned regions having a predetermined thickness configured to corrosively fail after a set time period when exposed to a corrosive environment that is different from each other thinned region of the plurality of thinned regions;
