THREE DIMENSIONAL INTEGRATED CHARACTERIZATION AND ARCHIVING SYSTEM (3D-ICAS)

PDF Version Also Available for Download.

Description

The overall objective of this project is to develop an integrated system that remotely characterizes, maps, and archives measurement data of hazardous decontamination and decommissioning (D&D) areas. The system will generate a detailed 3-dimensional topography of the area as well as real-time quantitative measurements of volatile organics and radionuclides. The system will analyze substrate materials consisting of concrete, asbestos, and transite. The system will permanently archive the data measurements for regulatory and data integrity documentation. Exposure limits, rest breaks, and donning and removal of protective garments generate waste in the form of contaminated protective garments and equipment. Survey times are ... continued below

Description

The overall objective of this project is to develop an integrated system that remotely characterizes, maps, and archives measurement data of hazardous decontamination and decommissioning (D&D) areas. The system will generate a detailed 3-dimensional topography of the area as well as real-time quantitative measurements of volatile organics and radionuclides. The system will analyze substrate materials consisting of concrete, asbestos, and transite. The system will permanently archive the data measurements for regulatory and data integrity documentation. Exposure limits, rest breaks, and donning and removal of protective garments generate waste in the form of contaminated protective garments and equipment. Survey times are increased and handling and transporting potentially hazardous materials incur additional costs. Off-site laboratory analysis is expensive and time-consuming, often necessitating delay of further activities until results are received. The Three Dimensional Integrated Characterization and Archiving System (3D-ICAS) has been developed to alleviate some of these problems. 3D-ICAS provides a flexible system for physical, chemical and nuclear measurements reduces costs and improves data quality. Operationally, 3D-ICAS performs real-time determinations of hazardous and toxic contamination. A prototype demonstration unit is available for use in early 2000. The tasks in this Phase included: (1) Mobility Platforms: Integrate hardware onto mobility platforms, upgrade surface sensors, develop unit operations and protocol. (2) System Developments: Evaluate metals detection capability using x-ray fluorescence technology. (3) IWOS Upgrades: Upgrade the IWOS software and hardware for compatibility with mobility platform. The system was modified, tested and debugged during 1999 and 2000. The 3D-ICAS was shipped on 11 May 2001 to FIU-HCET for demonstration and validation of the design modifications. These modifications included simplifying the design from a two-vehicle system to a single mobile platform, integration of the XRF sensor for enhanced substrate analysis and upgrading of the IWOS operating system. Several of the system's power supplies were accidentally damaged upon power on because FIU wired 3 phase AC power to the system instead of the requested single phase. Repairs were made in the field to the damaged power supplies but 3 of 5 days time were lost to complete the repairs. Once the repairs were made CyTerra was able to demonstrate the CLR mapping and the movement of the sensor probe to selected locations on the test wall. The XRF sensor was also demonstrated on a stainless steel substrate. A surrogate solution was determined to be below the detection threshold. The radionuclide and GCMS sensors were not demonstrated due to either failed power supply or lack of time remaining in the schedule. The GCMS failure was partially the result of the debugging activities that took place during the week for assessing electrical damage. Specifically, GCMS electronic modules, which control the heating of two of gas transfer elements, may have been damaged during field debugging that was required. Given the financial constraints of the program, CyTerra Corporation decided to return the equipment to Waltham facilities for further assessment. We believe the principles of operation were shown, however a complete demonstration did not occur due to these difficulties.
