With over 25 years of plant process computer experience, C3-ilex recognizes the unique issues faced by Utilities with their existing systems. C3-ilex is an experienced team working to provide tailored products and services to address these issues with an overriding goal of reducing O&M costs and improving plant performance. Our systems are designed to allow you to choose the migration path that is most valuable to you. You can choose a modular approach that leverages your legacy investment by phasing in a new system within an obsolescence program or by making a full investment to change out the entire system A sample of a number of solutions developed by C3-ilex are discussed below.  Transient Recording & Event Knowledge (C3-TREK) Data Acquisition System importer and exporter (DASie) Plant Process Computer System (PPCS) Control Room User Interface (CRUI) NUMAC & Core Monitoring Interfaces (NI) Quality Management System (QMS) CROSSFLOW Integration System Maintenance
Transient Recording and Event Knowledge (C3-TREK)C3-TREK is a high performance Transient Recording and Event Knowledge solution developed by C3-ilex as a replacement product for outdated Nuclear Utility Monitoring systems. C3-TREK interfaces with high-speed data acquisition systems, uses OSIsoft Corporation’s powerful ECHO Historian to archive large amounts of high-resolution data, continuously monitors critical plant parameters, generates event reports and imports/exports data to other plant computer systems for further analysis. C3-TREK was designed for full integration with OSIsoft’s PI System products, enabling use of PI tool sets for data presentation and analysis. C3-TREK features include:
C3-TREK provides a cost effective, state-of-the-art solution for Plant Monitoring applications. It represents a dependable resource for capturing and archiving high-speed data essential for event detection, compliance reporting and plant operational analysis.
Data Acquisition System Importer/Exporter (DASie)
Plant Process Computer System (PPCS)When considering a Plant Process Computer System replacement, the question arises as whether or not to embark upon a wholesale or modular replacement of its elements. More often than not, the case for a phased migration approach will prevail. A phased, modular migration strategy for critical plant computer systems is based on planned replacements of the most limiting technology pieces driven by need and budget considerations. The phased migration approach offers a flexible, potentially lower cost and lower risk solution than wholesale replacement, which is generally associated with cost overruns and outage extensions. The core of a phased migration strategy hinges on a flexible modular system that can accept data streams from multiple data acquisition systems and computers and consolidate this data for presentation in control room displays and for the plant historical archive. The ability to test the new system in parallel with the existing system is also a key to a smooth installation. C3-ilex through its C3-TREK, DASie and CRUI products can help you implement a phased approach for replacement of your obsolete Plant Process Computer System elements. We have also developed software tools that simulate the legacy systems as well as fiber optic splitters and switches to facilitate parallel testing. Please contact us for additional information.
Control Room User Interface (CRUI)Many nuclear plant control room information and display systems are in urgent need of updating. However, re-engineering costs, identifying and qualifying proven products, and system validation are a few reasons why significant modifications to existing systems have been postponed. For Utilities in this situation, C3-ilex can provide assistance in formulating a solution and developing the business case required for a Control Room User Interface (CRUI) replacement. The evaluation includes:
A recent C3-ilex project involved a CRUI replacement study based on utilization of OSIsoft’s suite of PI products. The objective was to resolve equipment obsolescence issues, retain existing functionality, and support an integrated, common user interface across the Utility organization (i.e., Operations, Engineering, Management). NUMAC and Core Monitoring Interfaces (NI)For Nuclear Utilities using General Electric NUMAC devices, C3-ilex has developed replacement software for legacy Core Monitoring System (CMS) data interface applications. The C3-TREK-NI functions consist of Windows Services and Windows Client user-interface applications. The NUMAC Interface (NI) Services will usually run on the Plant Process Computer (PPC) or alternatively on a separate PC. Replacement applications are available for plants using NUMAC RWM, ATIP and/or PRNM devices. In addition, C3-ilex has developed communication diagnostic software for the DASie that features a listen mode allowing the capture of one or more specific NUMAC message numbers. It is typically employed with a fiber optic splitter on the transmit and receive pair. It enables the troubleshooting of NUMAC message communication. Contact us for additional information on the benefits of our solution which include;
In addition to our solutions, C3-ilex has been involved with the development and interfaces to a number of systems. C3-ilex, utilizing design requirements specified by a major supplier of nuclear fuel, C3-ilex performed software development and maintenance services for their core monitoring software product. This product is used by the nuclear power industry to support plant operation and to ensure that nuclear fuel thermal limits as mandated by plant technical specifications are not exceeded. In addition to supporting the base core monitoring software product, development work included design of a windows-based graphical user interface using object-oriented design techniques. Responsibilities also included the development and implementation of software development procedures and configuration control mechanisms consistent with recommendations provided in Nuclear Regulatory Commission guidelines. Related projects in this area involved the development of Core Monitoring System interfaces with a variety of Plant Process Computers and the Power Range Neutron Monitoring System.
Quality Management System (QMS)For those Utilities struggling with managing internal software development, C3-ilex has developed a Quality Management System that simplifies the software development life cycle. C3-QMS systematically tracks your software engineering process from top level functional requirements through design specification, module development, software build and testing. C3-QMS assures quality driven software deliveries and establishes an ISO 9000 Compliant Audit Trail. QMS utilizes Microsoft Access and can be loaded on a standard PC or server.  QMS is a user friendly tool that, in conjunction with the supplied user manual, can be populated by any individual with basic computer skills. However, the usefulness of QMS is dependent on the definition of the functional requirements and software architecture. C3-ilex can also provide support services to assist Utilities in establishing these input parameters, and tailoring the QMS to match your specific software development cycle. Contact us to see how this tool can help your organization get your software development and integration activities under control.
CROSSFLOW IntegrationUtilities worldwide are utilizing the Westinghouse CROSSFLOW system for reducing core thermal power uncertainty. The CROSSFLOW ultrasonic flow measurement system, developed by Westinghouse Electric Company, LLC and Advanced Measurement & Analysis Group, Inc., enables Nuclear Power generators to more accurately measure feedwater flow and reduce the uncertainty associated with this measurement. A reduction in feedwater flow uncertainty, applied as a correction factor to the Plant Process Computer (PPC) feedwater flow readings, translates directly to a reduction in the uncertainty of the calculated core thermal power, allowing the plant to operate at a higher power rating. Providing an interface between the CROSSFLOW system and the PPC, with the resultant interface to other plant data and HMI systems, allows automatic correction of PPC feedwater flow parameters and offers significant benefits over a stand-alone system. These benefits include:
Integration of multiple plant computer systems requires a well thought out project plan, and an experienced system integration team. The C3-ilex team meets these requirements. C3-ilex is an experienced integrator of the Westinghouse/AMAG CROSSFLOW system and can provide the services and software required to successfully interface your CROSSFLOW system with other plant computer systems. 
System MaintenanceFor those customers who frequently look to outside resources for support of their Plant Process Computer System operations, C3-ilex can provide this assistance through a Software Maintenance Agreement program. This program is structured to provide both rapid response to operational problems and a vehicle to obtain software development support for minor modifications or enhancements. A typical Software Maintenance Agreement would include the following elements:
