Design of Pressurized Water Reactor Simulator Using USB NI-6009 Data Acquisition Module

In this work, the pressurized water reactor power model has been simulated using Lab view Data Acquisition module. Energy is the focal point of any investigation at present in the research domain and this work contributes to understand the mechanism and challenges of clean energy generation. The development of GUI for Pressurized Water Reactor is carried out using Labview and the power mode of the control panel was analyzed using test set up. This work and observations are strictly in adherence to only academic standards and is useful only for academic purpose. This work on efficient energy generation is very significant as clean energy is the focal point of any application or contemporary research.

World economic progress depends on the Energy.Today energy is the most important aspect for human living.World needs increased energy supply in the next two decades and especially clean energy.The demand for electricity or clean energy is increasing consistently and it is expected to rise by more than two-thirds from 2011 to 2035.
Nuclear energy constitutes to about 11% of the world's electricity and in 2012, 42% of primary energy used was converted into electricity according to the Organization for Economic Cooperation and Development (OECD) countries [4 and 6].Renewable energy sources such as solar and wind are expensive in terms of per unit of output and are intermittent but can be helpful at the margin in providing clean power.Nuclear power is the environment friendly and gives clean energy.

The operation of a Pressurized Water
Reactor is pretty much like a conventional plant.Pressurized Water Reactor produces heat energy from splitting of heavy atoms rather than by burning coal, oil, gas, or another fuel.This heat is used to boil water to make steam that drives giant steam turbines connected to generators as a result of which the electricity is generated.
The operation and functionality of the various Pressurized Water Reactors can be graphically illustrated using graphical programming language.The LabView Software is one such advanced graphical programming tool.Using NI DAQ module and LabVIEW software, the effect on the performance of various Pressurized Water Reactor Simulators design is considered.This gave adequate motivation to consider this work and it has been taken to the application level in the form of Pressurized Water Reactor Simulator with Data Acquisition [1 and 5] Many researchers have investigated this domain with distinct challenges and suggested possible solutions.Few notable contributions are: Arun et al (2014) have demonstrated the Monitoring and controlling the fuel supply for increasing the Fuel efficiency and safety.Here they have modeled fuel supply System in LabVIEW for easy access of the system.The communication between the LabVIEW and PLC is done by using Object Linking and Embedding for Process Control (OPC) server software.BinduPillai et al ( 2013) have demonstrated the automated system that improves the system efficiency, plant monitoring, productivity and the operation management of the plant.They focuses on various aspects of automation of laboratory based mini-thermal power plant and virtual simulation of same [2].R.K. Sinha et al (2005) have developed the Stage-3 of nuclear programme in India using thorium based Advanced Heavy Water Reactor (AHWR) working principle and design 3 .

The existing system makes use of Sequential Programming Languages for the development of Pressurized Water Reactor Simulator.This involves lengthy and time consuming code-writing process.Detection and Rectification of errors in coding is difficult.This The basic block diagram of the proposed work is represented in Figure 1.Whereas, Figure 2 shows the Circuit Diagram Of Proposed Pressurized Water Reactor Simulator.Here USB NI-6009 used as the Main Module for Data Acquisition system that shown in Figure 3.
With recent bandwidth improvements and new innovations from National Instruments, USB has evolved into a core bus of choice for measurement applications.
The NI USB-6008 and USB-6009 are lowcost DAQ devices with easy screw connectivity and a small form factor.With plug-and-play USB connectivity, these devices are simple enough for quick measurements but versatile enough for more complex measurement applications.
The simplified PWR nuclear power plane model is as shown in the Figure 3    Data is stored in PC through the path specified in LabVIEW software and the result will be in the form of Excel.Real time data is stored continuously in personal computer to monitor the data accurately.This facilitates to monitor post failures in any part in the Pressurized Water Reactor.
