DATA ACQUISITION SYSTEM FOR XA9846763 THE 3 MW TRIGA REACTOR AT AERE SAVAR* A.O.M. ABDUL AHAD Bangladesh Atomic Energy Commission, Atomic Energy Research Establishment, Institute of Nuclear Science and Technology, Reactor Engineering and Control Division, Dhaka, Bangladesh Abstract A 3 MW TRIGA Mark II research reactor control console has been studied in detail and the channels have been selected for monitoring, display and record using the microcomputer. Information from these channels are fed to the computer through hardware like buffer, AD converter, multiplexer, etc. for continuos display and permanent records using video monitor, printer and diskettes. Besides, the information from the console, other information like operating time, power, total burnup of fuel, operating persons, etc. are also available, With very little modifications in both hardware and software, the data logging system is now running successfully. INTRODUCTION A 3 MW TRIGA Hark II research reactor has become operational at Atomic Energy Research Establishment, Savar Dhaka since September, 1986. The reactor is being used mainly for Isotope production, neutron radiography, activation analysis and for other experiments of academic use. A triple axes spectrometer has also been installed at the reactor facility. The Control and Instrumentation group of Reactor Engineering and Control Division is engaged in R & D works in automatic control based system, and control & instrumentation of nuclear reactors. Under this project a microcomputer based system is being designed and developed to automatically monitor and record all operational parameters and relevant Information of the reactor in an efficient manner. The reactor control console has been studied in detail and the channels as per attached list (Annexure 1) have been selected for monitoring, display and record using the microcomputer.
