Immobilization of incinerator ash in a concrete matrix

Description: The ashcrete process will solidfy ash generated by the consolidated Incinerator Facility (CIF) at the Savannah River Plant (SRP). The ashcrete unit produces ashcrete, a stable cement-based wasteform, by remotely adding cement and water and tumbling drums of ash. Ashcrete product homogeneity, temperature rise during setting, and compressive strength were measured and product formulations were developed for several nonradioactive dry ash types. Saturation level and wet and dry ash densities for s… more

Los Alamos upgrade in metallographic capabilities

Description: The Los Alamos Wing 9 Hot Cell Facility is in the process of upgrading their metallographic sample preparation and examination capability. The present capability to grind, polish and etch samples from reactor fuels and materials has been in operation for 18 years. Macro photography and alpha and beta-gamma autoradiography are an important part of this capability. Some of the fast breeder reactor experiments have contained sodium as a coolant. Therefore, the capability to distill sodium from som… more

Information extraction from noisy televiewer logs of inclined holes in hard rock

Description: A feature-extraction method was adapted from satellite image-processing to the problem of extracting information from extremely noisy and narrow-range televiewer imagery from GT-2 at Fenton Hill. From televiewer logs, 733 structures were recovered, compared with 42 from core. The average spacings were 3.13 and 0.55 feet, respectively, indicating that the televiewer yielded only 17.5% of the information available from core. Two televiewer runs overlapped between 4000 and 4275 feet depth, but no … more

Nuclear fuel assembly identification using computer vision

Description: A new method of identifying fuel assemblies has been developed. The method uses existing in-cell TV cameras to read the notch-coded handling sockets of Fast Flux Test Facility (FFTF) assemblies. A computer looks at the TV image, locates the notches, decodes the notch pattern, and produces the identification number. A TV camera is the only in-cell equipment required, thus avoiding complex mechanisms in the hot cell. Assemblies can be identified in any location where the handling socket is visibl… more

Remote video radioactive process evaluation, Savannah River Site

Description: Specialized miniature low cost video equipment has been effectively used in a number of remote, radioactive, and contaminated environments at the Savannah River Site (SRS). The equipment and related techniques have reduced the potential for personnel exposure to both radiation and physical hazards. The valuable process information thus provided would not have otherwise been available for use in improving the quality of operation at SRS.

Manipulators in teleoperation

Description: Teleoperated manipulators represent a mature technology which has evolved over nearly 40 years of applications experience. The wide range of manipulator concepts developed thus far reflect differing applications, priorities, and philosophies. The technology of teleoperated manipulators is in a rapid state of change (just as are industrial robotics) fueled by microelectronics and materials advances. Large strides in performance and dexterity are now practical and advantageous. Even though improv… more

Automated visual direction : LDRD 38623 final report.

Description: Mobile manipulator systems used by emergency response operators consist of an articulated robot arm, a remotely driven base, a collection of cameras, and a remote communications link. Typically the system is completely teleoperated, with the operator using live video feedback to monitor and assess the environment, plan task activities, and to conduct the operations via remote control input devices. The capabilities of these systems are limited, and operators rarely attempt sophisticated operati… more

Development of a geothermal acoustic borehole televiewer

Description: Most geothermal wells are drilled in hard rock formations where fluid flow is through systems of open fractures. Productivity of these wells is usually determined by the extent of intersection of the wellbore with the fracture system. A need exists for fracture mapping methods and tools which can operate in a geothermal environment. In less hostile environments, the acoustic borehole televiewer has been shown to be a useful tool for determining location, orientation, and characterization of fra… more

PINEX-2 experiment: concept verification of an inherent shutdown mechanism for HCDA's. [LMFBR]

Description: PINEX-2 was a dual-objective experiment to continue development of the Pinhole Imaging (PINEX) system for monitoring fuel motion, and to further demonstrate the feasibility of internal fuel motion as a mechanism for mitigating the consequences of hypothetical LMFBR accidents. A special fuel pin with a pre-fabricated central hole in the fuel, insulator, and reflector was pre-irradiated in the General Electric Test Reactor and subjected to a simulated 5$/sec transient overpower excursion in the T… more

Developments in the LASL Fuel Pin Imaging System: PINEX-3A

Description: The LASL Fuel Pin Imaging System was evaluated using a series of 10 TREAT transients, each of approx. 240-MW peak power. HEDL provided the fuel-ejection type capsule with annular fuel pellets. The pin visibility threshold was determined to be approx. 20-MW of TREAT power (approx. 130 W/g), almost an order of magnitude improvement over our PINEX-2 threshold. The impact of changes in instrumentation, imaging apertures, and fluors that produced the improved sensitivity are reported. Results of a t… more
