A facility safety envelope requires management of activities to ensure no unacceptable radiological or chemical hazards to the public, site worker and environment occur. While appropriate design and construction methods ensure an initial physical plant configuration, what actions must an operating Facility take to ensure the physical plant continues to meet a safety configuration throughout Facility life? While a physical walk down of the plant is a tried and true method to confirm conditions, what other methods must be used when a walk down is not possible? What inspection methods are used when balancing budget pressures against obtaining inspection data? The periodic inspections of the H-Canyon Exhaust Tunnel are performed remotely. The 2015 remote Tunnel inspection has been the most successful inspection to date. This presentation highlights the continued lessons learned with the most recent 2015 remote Tunnel inspection. These lessons learned are applicable to Facilities considering or performing remote inspections. The Recovery Crawler Project was tasked with determining if the 2014 Inspection Crawler could be retrieved, perform the retrieval if feasible and complete the inspection of the remaining sections of the exhaust tunnel that were not previously performed. The objectives for the project were met, the Inspection Crawler was deemed unusable and left in place and the Recovery Crawler performed the complete 143 meters (470 feet) of tunnel inspection and an additional 55 meters (180 feet) of exhaust tunnel inspection not previously completed. The remote inspection of a 60+ year operating Canyon Exhaust tunnel is a complex endeavor requiring close coordination of multiple organizations, adherence to Conduct of Operations, Radiological Safety, Worker Safety, etc. principles as well as alignment with Facility Safety Basis requirements. This paper discusses the challenges, actions required getting ready for the 2015 recovery and continued inspection and the hazards encountered performing the actual recovery/inspection. (authors)
