This book examines the different spatial control techniques for regulation of spatial power distribution in advanced heavy water reactors (AHWR). It begins with a review of the literature pertinent to the modeling and control of large reactors. It also offers a nodal-core model based on finite difference approximation since the AHWR core is considered to be divided into 17 relatively large nodes. Further, it introduces a nonlinear model characterizing important thermal hydraulics parameters of AHWR and integrates it into the neutronics model to obtain a coupled neutronics-thermal hydraulics model of AHWR. The book also presents a vectorized nonlinear model of AHWR and implements it in MATLAB/Simulink environment. The model of the reactor is then linearized at the rated power and put into standard state variable form. It is characterized by 90 states, 5 inputs and 18 outputs. Lastly, it discusses control techniques for a nonlinear model of AHWR. This book will prove to be a valuable resource for professional engineers and implementation specialists, researchers and students.

Dr. A P Tiwari joined BARC through the 28th batch of BARC training school. He completed his BSc in Electrical Engineering from Aligarh Muslim University in 1984 and his PhD in Systems and Control Engineering at IIT Bombay in 2000. During his early career at BARC, he worked on control analysis of the Dhruva reactor and control system design of the Purnima-III U-233 fuelled reactor. From 19952002, he worked on the development of the Liquid Zone Control System for the 540 MWe PHWR. He was also responsible for the design of process control and instrumentation systems and control algorithms for AHWR. His research areas include time-scale and singular perturbation methods in control, multivariable control, and sliding mode control with application to nuclear reactors. He has guided a number of PhD and MTech students at IIT Bombay and HBNI and is actively involved in research in the area of modern control systems design for large reactors, namely PHWR and AHWR. He received the DAE Science and Technology Award in 2003 and Group Achievement Awards in 2006, 2012 and 2013 for his various activities. He also received the HBNI Distinguished Faculty Award in 2015.
