چکیده انگلیسی
Chlorine-induced stress corrosion cracking is a degradation mechanism of concern for dry storage of used nuclear fuel. Remote detection of chlorine deposited on the stainless steel canister surface presents a challenge, since no direct line-of-sight is available. We demonstrate the design and use of double-pulse laser-induced breakdown spectroscopy installed on a robotic system for remote detection and measurement of the canister surface chlorine concentration. The system meets the stringent requirements of dry cask storage inspection environment, especially the constrained space. The externally located pulsed laser, spectroscopic instrumentation, and data acquisition setup were interfaced to a robotic delivery car using a pair of 25-m long optical fibers. We discuss the design and construction details of the chlorine detection system and its detection performance in both laboratory and field-deployable configurations. We show that chlorine concentrations as low as 10 mg/m2 can be measured in field-compatible operations.
