Electronic Visions, Inc. (EVI) offers a combined background of over 100 man-years in software solutions. EVI areas of expertise include electric utility systems, industrial automation systems. EVI employees supply various electric utility system software solutions for many utility facilities in America.
EVI employees have been involved with plant monitoring system replacements at nuclear power plants across America. EVI's Plant Integrated Computer System (PICS) replacement projects included both host computer replacement and full system replacements including field equipment. PICS also interfaces with plant training simulators to provide a consistent operator experience. Some of the most recent power plants that EVI has been involved with include:
EVI also provides maintenance support contracts for any plant that requires the world-class expertise that only EVI can provide. Some of our customers in this area are:
EVI has developed a state-of-the-art fully redundant field-proven replacement system for the Sorrento Electronics PC-11 and RM11R radiation monitoring system. EVI is providing replacements for Sorrento systems at two nuclear power plants. These plants are:
Electronic Visions, Inc. provides Plant Monitoring Systems solutions to the nuclear power plant industry. Our Radiation Monitor Computer System (RMCS) component helps maintain the safe function of plants by collecting real time data from area radiation monitors and displaying this data to plant operators and engineers.
Advanced Features: The RMCS is built upon the rock-solid PICS software used on many Plant Process Computers. This software in concert with the latest Windows Operating Systems, industry standard workstations, network switches and data acquisition equipment provides a robust, highly reliable system. Alarming, archiving, database management, point controls, trends, Flow Diagrams, reports, and security features are all inherent features of any PICS that hosts the RMCS applications. Industry Standards: Our open system architecture allows the RMCS to be easily interfaced with other plant systems with your site’s LAN. The ability to integrate customer applications developed using Microsoft tools enables users to manage data for individual needs and special purposes, extending the benefits beyond operators to engineers and secondary users. Cyber: EVI has implemented significant architectural changes to our products in response to regulatory requirements and to fully meet the recommendations of NEI 08-09. Operator Friendly: The RMCS delivers the data through point and click menus that are easily configured for your plant as well as individual workstations. Operators can have a separate set of views from engineers or radiation protection personnel. Current values or historical data can be displayed in trends, bars, plant flows or downloaded into a spreadsheet. Database Driven: The point I/O list and associated PICS files and tables reside in our database server. Access to the PICS real-time data is available using standard desktop productivity tools via DDE. Display Station: The RMCS Human-Machine interface (EV11) builds on EVI's extensive experience customizing displays for previous PICS installations to provide an easy-to-use RMCS interface experience. The EV11 provides an interface to both real time and historical data.
The RM-80 Microprocessor is designed for two types of applications: area configurations with stand-alone detectors and process configurations with detectors integrated into skid assemblies which contain detector support equipment such as pumps, valves, flow sensors, flow control valves, and samplers. Area configurations are used for conventional area monitoring, adjacent-to-line, and inline process monitoring. Process configurations are used to monitor a sample from a liquid, airborne process stream, or a local atmosphere.
The function of the RM-80 Microprocessor is to control the operation of a radiation monitor assembly which contains one or more radiation detectors and the detector support equipment. The RM-80 Microprocessor performs data acquisition from detectors, process sensors, and digital status inputs through various boards as shown in the RM-80 block diagram. An RM80 Microprocessor can accept up to four inputs form pulse type detectors and up to two inputs from current type detectors. Data acquisition is followed by data reduction for detector and sensor inputs which includes validity checking, digital filtering to reduce statistical fluctuations, conversion, and compression. Compression consists of taking current values calculated every 0.6 and 6 sec and generating history files within twenty-four 10-min averages, twenty-four 1-hr averages, and twenty-eight 24-hr averages. Data analysis consists of comparing reduced data against alarm setpoints stored in the RM-80 Microprocessor data base. An alarm condition in any channel turns on a local alarm light and horn, changes the state of alarm relay contacts, and sets an alarm status bit for external communications.
Both types of RM-80 Microprocessors perform the following test functions:
Loss of Detector Counts - Failure of the RM-80 Microprocessor to receive a count over a certain period of time will cause a failure alarm. Checksource Test - The RM-80 Microprocessor will initiate a checksource test upon operator request. This function can also be set to occur on a fixed interval. Insufficient count received from a checksource test will cause a failure alarm.
An RM-80 Microprocessor for process monitors can provide the following control functions:
Flow Control - The sample flow rate is obtained from a flow sensor on the monitor. A flow rate outside the setpoint plus/minus a deadband will cause the RM-80 Microprocessor to adjust the monitor's flow control valve in the appropriate direction until the flow rate is within limits. Pump Control - The RM-80 Microprocessor shuts a pump off when the flow rate drops below a low-flow setpoint for a specific period of time. The RM-80 Microprocessor will also start or stop a pump upon operator request. Purge Control - The RM-80 Microprocessor will actuate purge valves upon operator request. The purge function can also be set to occur on a fixed interval. Isokinetic Control - Process flow rate input to the RM-80 Microprocessor can be tracked such that the ratio between sample and process flow rates (isokinetic ratio) is maintained at a setpoint plus/minus a deadband.
The RM-80 Microprocessor is designed to operate as a stand-alone device in conjunction with its detector and support equipment. For external communications, the RM-80 Microprocessor has three serial communications ports. Two redundant communication ports are used to communicated between the RM-80 Microprocessor and an integrated RMCS. The third port is used for safety-related and other critical monitors to communicate with a remote, dedicated RM-23A Control/Display module. RMCS and an RM-23A Control/Display Module continuously poll the RM-80 Microprocessor for radiation level and operation status.
