Abstract
The latest release of Canberra’s Hybrid K-Edge Software (CHKED) provides the capability to remotely monitor and optionally control Hybrid K-Edge/XRF instruments using client-server software architecture. HKED systems are critically important for near-real time accountancy (NRTA) of special nuclear material by regulatory authorities, and for process control at various stages of operation for nuclear fuel reprocessing facilities. The remote monitoring enhancement enables Safeguards inspectors to have easier access to data at distant sites as well as more immediate access to systems operations. This is particularly relevant in situations with multiple stakeholders, shared instrumentation, and varied and controlled uses of the system’s calibrations and data. The benefits of reduced travel costs and travel time are significant factors given the ever increasing pressures on Safeguards budgets and resources. Remote access is also advantageous to the facility in terms of reduced interruption of operations, particularly when extensive, periodic calibration campaigns and state-of-health checks must be performed. Within the facility itself, where ‘remote’ can be outside a hot cell or restricted area, the benefits are immediate access to information on system state-of-health and operational conditions, time savings for certain routine operational tasks, reduced worker exposure, and reduced waste generation. These add up to a reduced cost-of-ownership for the facility. The client-server functionality can also benefit the training of inspectors, operators, analysts, or researchers by simplifying computer setup and maintenance in classroom set-tings with simultaneous users. The software supports remote access over Virtual Private Network (VPN) and allows multiple Operations and Data-Review clients to connect to the system. Built on the Windows Communications Framework (WCF), CHKED uses client-server functionality for both local and remote client access to servers on the network. The range of access and control in the CHKED client-server software will be outlined, including real-time monitoring of a system in use, data accessibility based on predefined user privileges, and controls to ensure safe operation of the instrument. Some enhanced features and capabilities have also been implemented and tested, including an automated beam-sample alignment utility and flexibility in the batch sequencing process for the measurement of multiple samples
