We owe a debt of gratitude to Dennis Wilkinson, born 102 years ago today. Dennis did so much for the nuclear power industry—both in the Navy and in the commercial sector. When people first met him, he invariably stuck out his hand, grinned, and said, “Hi, I’m Dennis.” No pretense, no pomposity, no self-importance. Supremely confident and brilliant, he was also compassionate and warm with an engaging sense of humor. Many people he met became life-long friends, as he often said that “friendship is forever.”
