To demonstrate endurance of the JSFR selector-valve, an endurance experiment under high temperature sodium has been conducted. From the results of the endurance under-sodium experiment using the mock-up of JSFR selector-valve, the endurance of the sampling pad can be ensured completely by setting the manufactured coating layer to 50m.
