AbstractAbstract
[en] The 18.14-metric-ton-capacity (20-ton) Load-Cell-Based Weighing System (LCBWS) prototype tested at the Oak Ridge (Tennessee) Gaseous Diffusion Plant March 20-30, 1984, is semiportable and has the potential for being highly accurate. Designed by Brookhaven National Laboratory, it can be moved to cylinders for weighing as opposed to the widely used operating philosophy of most enrichment facilities of moving cylinders to stationary accountability scales. Composed mainly of commercially available, off-the-shelf hardware, the system's principal elements are two load cells that sense the weight (i.e., force) of a uranium hexafluoride (UF6) cylinder suspended from the LCBWS while the cylinder is in the process of being weighed. Portability is achieved by its attachment to a double-hook, overhead-bridge crane. The LCBWS prototype is designed to weigh 9.07- and 12.70-metric ton (10- and 14-ton) UF6 cylinders. A detailed description of the LCBWS is given, design information and criteria are supplied, a testing procedure is outlined, and initial test results are reported. A major objective of the testing is to determine the reliability and accuracy of the system. Other testing objectives include the identification of (1) potential areas for system improvements and (2) procedural modifications that will reflect an improved and more efficient system. The testing procedure described includes, but is not limited to, methods that account for temperature sensitivity of the instrumentation, the local variation in the acceleration due to gravity, and buoyance effects. Operational and safety considerations are noted. A preliminary evaluation of the March test data indicates that the LCBWS prototype has the potential to have an accuracy in the vicinity of 1 kg

AbstractAbstract
[en] For the independent verification of UF6 cylinder masses by the International Atomic Energy Agency (IAEA) at uranium enrichment facilities, an 18-tonne capacity Load-Cell-Based Weighing System (LCBWS) has been developed. The system was developed at Brookhaven National Laboratory and the Oak Ridge Gaseous Diffusion Plant and calibrated at the US National Bureau of Standards. The principal components of the LCBWS are two load cells, with readout and ancillary equipment, and a lifting fixture that couples the load cells to a cylinder. Initial experience with the system demonstrates that it has the advantages of transportability, ease of application, stability, and an attainable accuracy of 2 kg or better for a full cylinder

AbstractAbstract
[en] To provide for the verification of UF6 cylinder masses by the International Atomic Energy Agency at uranium enrichment facilities handling large-capacity UF6 cylinders, an 18.14-metric-ton-capacity (20-ton) Load-Cell-Based Weighing System (LCBWS) has been developed. This system, which was developed at Brookhaven National Laboratory and the Oak Ridge Gaseous Diffusion Plant (ORGDP) and calibrated at the US National Bureau of Standards, is described along with results from its initial testing. The principal components of the LCBWS are two 11.34-metric-ton-capacity (12.50-ton) load cells (with associated readout and ancillary equipment) and a lifting fixture that couples the load cells to a UF6 cylinder. Results from testing of the system at the ORGDP followed by a comparative analysis of the apparent cylinder masses vs brass given by the LCBWS with the stated ORGDP accountability scale values indicates that the accuracy of the LCBWS is +- 1 kg and that the precision of an individual measurement is +- 2 kg. Initial experience wth the 18.14-metric-ton-capacity (20-ton) LCBWS indicates that it has the advantages of portability, ease of assembly and use, and high accuracy. Further testing to establish the long-term stability of the calibration and overall reliability of the system is described along with future work for the redesign of the system's readout and ancilliary equipment to ensure that a user-friendly interface for operations is available
