  • neptune above ground storage Tank Inspection robot system
    IEEE Robotics & Automation Magazine, 1995
    Co-Authors: Hagen Schempf, Brian Chemel, Nathan Everett
    Abstract:

    The Neptune system allows unmanned entry and sensor data collection in above-ground storage Tanks (ASTs). The sensors are immersed in the petroleum product and uses video and ultrasonics to ascertain from the inside-out the state of corrosion of the floor and side-walls. This eliminates the need to empty or clean the Tanks and also avoids the required human walk-through Inspection, which results in a very sparse data set from which the Tank's state must be statistically extrapolated. >

  • Neptune: Above-Ground Storage Tank Inspection Robot System
    IEEE Robotics and Automation Magazine, 1995
    Co-Authors: Hagen Schempf, Brian Chemel, Nathan Everett
    Abstract:

    The Neptune system is a mobile robot system used to remotely inspect above-ground storage Tanks (ASTs) containing petroleum products. Neptune ascertains the state of corrosion of the floor and side-walls according to the guidelines laid out by the American Petroleum Institute (API). The robot system allows unmanned entry and sensor data collection in ASTs without the need to empty or clean the Tanks nor the required human walk-through Inspection. The complete system comprises: a robot crawler vehicle suitable for classified locations which carries visual and ultrasonic sensors; a deployment pod atop the Tank which lowers and retrieves the crawler; an in-Tank acoustic positioning system to chart and control the location of the robot; and an external remote control console utilizing commercial and custom software for display, planning, and control tasks. The crawler pod and navigation systems are all designed for certification in such hazardous environments, classified as Class I, Division I, Group D

  • ANNUAL RADIOACTIVE WASTE Tank Inspection PROGRAM - 2011
    2012
    Co-Authors: B. West, R. Waltz
    Abstract:

    Aqueous radioactive wastes from Savannah River Site (SRS) separations and vitrification processes are contained in large underground carbon steel Tanks. Inspections made during 2011 to evaluate these vessels and other waste handling facilities along with evaluations based on data from previous Inspections are the subject of this report. The 2011 Inspection program revealed that the structural integrity and waste confinement capability of the Savannah River Site waste Tanks were maintained. All Inspections scheduled per SRR-LWE-2011-00026, HLW Tank Farm Inspection Plan for 2011, were completed. Ultrasonic measurements (UT) performed in 2011 met the requirements of C-ESR-G-00006, In-Service Inspection Program for High Level Waste Tanks, Rev. 3, and WSRC-TR-2002-00061, Rev.6. UT Inspections were performed on Tanks 25, 26 and 34 and the findings are documented in SRNL-STI-2011-00495, Tank Inspection NDE Results for Fiscal Year 2011, Waste Tanks 25, 26, 34 and 41. A total of 5813 photographs were made and 835 visual and video Inspections were performed during 2011. A potential leaksite was discovered at Tank 4 during routine annual Inspections performed in 2011. The new crack, which is above the allowable fill level, resulted in no release to the environment or Tank annulus. The location of the crack is documented in C-ESR-G-00003, SRS High Level Waste Tank Leaksite Information, Rev.6.

  • ANNUAL RADIOACTIVE WASTE Tank Inspection PROGRAM- 2007
    2008
    Co-Authors: B. West, R. Waltz
    Abstract:

    Aqueous radioactive wastes from Savannah River Site (SRS) separations and vitrification processes are contained in large underground carbon steel Tanks. The 2007 Inspection program revealed that the structural integrity and waste confinement capability of the Savannah River Site waste Tanks were maintained. A very small amount of material had seeped from Tank 12 from a previously identified leaksite. The material observed had dried on the Tank wall and did not reach the annulus floor. A total of 5945 photographs were made and 1221 visual and video Inspections were performed during 2007. Additionally, ultrasonic testing was performed on four Waste Tanks (15, 36, 37 and 38) in accordance with approved Inspection plans that met the requirements of WSRC-TR-2002- 00061, Revision 2 'In-Service Inspection Program for High Level Waste Tanks'. The Ultrasonic Testing (UT) In-Service Inspections (ISI) are documented in a separate report that is prepared by the ISI programmatic Level III UT Analyst. Tanks 15, 36, 37 and 38 are documented in 'Tank Inspection NDE Results for Fiscal Year 2007'; WSRC-TR-2007-00064.
