ACKNOWLEDGMENTS

I would like to express the deepest appreciation to my committee chair, Professor Nader
Bagherzadeh, for his great attitude and infinite support. He continually and convincingly
conveyed a spirit of adventure with respect to research in the nuclear field. Without his
guidance and persistent assistance, this thesis would not have been possible.

I would like to thank my committee member, Professor Jean-Luc Gaudiot for his support
and acceptance to be a member of my thesis committee.

I would like to thank my distinguished committee member, Professor Najmedin Meshkati
from the University of Southern California, USC, who has spared no efforts to guide me,
share his literature work, and keep me posted on the latest nuclear safety matters.

Special thanks to Mr. Ted Quinn, a past ANS president, who shared with me his work in I&C
systems and referred me to the MIT Nuclear Plant Safety short program. His motivation for
learning about nuclear safety has the lasting effect.
