Honoring Los Alamos National Laboratory Fellows and their contributions to the institution.

Phil Young

Phil YoungIt is with great sadness that we bring you the news that Phil Young passed away this morning in Chicago. Phil was the leader of the applied nuclear physics group, T-2, and a Los Alamos National Laboratory Fellow. He was greatly instrumental in introducing model-based nuclear data evaluation methods into the group (and in the ND community at large), and was a generous mentor to several present and former members of the group. He continued to contribute to the field long after his retirement, and has his name associated with a significant fraction of the nuclear data in the Evaluated Nuclear Data File (ENDF) that is used in applications world-wide.

Phil set the highest standards for technical rigor and hard work, while also exhibiting a passion for nuclear reaction physics and data. He had a special combination of depth in experimental work, reaction modeling, and statistical analyses, and possessed an uncanny intuitive ability to know which measurements, and theory, to trust, when making evaluation decisions. Los Alamos National Laboratory’s capabilities in nuclear simulation have benefited greatly from his contributions.

Phil also recognized the importance of international collaborations for advancing applied nuclear physics, and served on numerous IAEA, and NEA, international steering committees that led successful collaborative efforts relevant to nuclear energy. Many of us saw him as a great ambassador for the US (and Texas!) as it engaged with international partners. Phil often reflected on the enjoyable times he spent with his family on long-term exchanges with colleagues and friends at the CEA.

Above all else, Phil was a true gentleman, a valued friend and colleague, whom those of us fortunate enough to have known him will miss greatly. We reflect with happiness on how his life touched, and impacted, us.

Phil was born on July 21, 1937, in Beeville, Texas, to Phillip (Sr.) and Allie B. Young. He was raised in Refugio, Texas with his brothers and sisters, Allie, John, Martha “Moye” and Michael Young.

Phil and Kay moved to Chicago in 2014 to pursue his cancer treatment at Loyola University Medical Center and to enjoy the amenities of city life. Phil fought a long battle with cancer with courage and grace. He will be remembered for his kind heart, generosity, and the big smiles he had for everyone.

Phil is survived by his wife Kay, his son Michael and wife Diane; daughter, Katie and her husband C.J. Pierce; daughter, Patty and her husband Bill Blake.
