DOE Grant No.
DE-FG02-05ER84303
Amount: $100,000
Storage
of radioactive wastes at many DOE facilities generates hazardous and explosive
gases. Sensitive and selective
monitoring of these gases is required to ensure the safe operation of storage
facilities. This project will develop
technology for multiple gas measurement using laser absorption
spectroscopy. The sensor approach will
be automated, self-calibrated, and self-checking; will use no consumable
chemicals; and will require little mainenance.
Phase I will identify the best spectral regions for the measurement. Laboratory experiments will be conducted to show
the feasibility of obtaining high sensitivity and wide dynamic range. Methods to reduce the sample volume will be
investigated.
Commercial Applications and Other Benefits as described by the awardee: Commercial applications are expected to include hazardous gas detection at industrial facilities; natural gas leak detection; and environmental monitoring for greenhouse gas detection, particle formation, and nitrogen cycle studies.
