Diligent boards fpga simulator#
The performance of this system was tested both on an analog reactor simulator and ITU (Technical University of Istanbul) TRIGA console.
In (Ciftcioglu and Geckinli, 1980b), the authors introduced a minicomputer-based on-line reactivity-meter. In (Khalafi et al., 2011), a digital reactivity meter was implemented using a Peripheral Interface Controller (PIC) microcontroller and a personal computer (PC). In the literature, there have been some successful designs and implementations of a digital reactivity-meters. To overcome the drawbacks related to analog computers, such as: thermal, temporal drifts and component obsolescence, digital platforms based on microprocessors and microcontrollers have also been used for a long time. From the earlier time, and as far as the physical implementation of this system is concerned, there was interest in implementation methods based on analog electronics. One of the most commonly used techniques were the inverse kinetics models, where the reactivity at each instant is determined by analyzing the variation of reactor power level using the point-reactor kinetic model (Hoogenboom and Van DerSluijs, 1988). Experimental results demonstrate that the system works well for both negative and positive reactivity insertions.Ī reactivity meter is a useful device to monitor and control a nuclear reactor core, and since its first introduction into the set of measuring instruments installed around a reactor, several methods and techniques were used for its design and implementation (Vegh et al., 2010 Khalafi et al., 2011 Auerbach and Carpenter, 1978 Ciftcioglu and Geckinli, 1980a). Real plant data, acquired from Es-salam research reactor, has been also used to confirm the online efficiency of the design. The design has been validated by comparing the obtained results with those proposed in the literature. This application will be essentially used to handle the communication with the embedded reactivity measurement system and to display the reactivity evolution curves through the time. A dedicated Graphical User Interface (GUI) has been also developed on a remote host computer.
Diligent boards fpga software#
Other secondary tasks, such as communication with the host PC, data storage and display have been devoted to the software application running on the Processing System (PS) part. The elementary hardware digital processing units, used to solve the inverse kinetics equations, have been implemented inside the Programming Logic (PL) part of the Zynq platform.
Diligent boards fpga generator#
As a primary design tool, the Xilinx System Generator (XSG) programming tool has been used. The aim of this paper is to present a Hardware/Software design approach for the real-time implementation of a digital reactivity meter on a Zynq SoC platform (FPGA: Field-Programmable Gate Array).
