Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Canada clears Darlington to produce Lu-177 and Y-90
The Canadian Nuclear Safety Commission has amended Ontario Power Generation’s power reactor operating license for Darlington nuclear power plant to authorize the production of the medical radioisotopes lutetium-177 and yttrium-90.
The Angelo F. Bisesti Scholarship was established in November 1994 for undergraduate students interested in nuclear power, preferably with a focus on new design and construction.
Angelo F. Bisesti (1942 - 1994) was born on Long Island and spent many years in car racing and other family experiences with his brothers in New York. He completed his bachelor’s degree program at San Francisco State University in Electrical Engineering and started his career with Ebasco and later with Stone & Webster in the design departments for early nuclear plants.
He joined Bechtel Power Corporation in 1971 and served as Lead Engineer for the Susquehanna BWR advanced control room development, testing installations and commissioning. Angelo then served as resident project manager for Unit 1, through fuel load. Susquehanna has been considered a model for the industry for construction, and had we continued building new plants, we would have followed the guidance and lessons learned in the Susquehanna construction program. In 1987, he joined Fluor Daniel as Senior Director of Power Marketing and was responsible for nuclear operating plant services and subsequently for advanced technology programs.
Angelo was best known for his abilities to lead technical programs in which everyone enjoyed participating. His personality brought out the best in everyone that came in contact with him, and his enthusiasm for quality and life was infectious.
Angelo was a member of the American Nuclear Society since 1986 and served as the Technical Program Chair for the 1991 ANS Winter Meeting Embedded Topical Meeting, “The Next Generation of Nuclear Plants - A Status Report,” which was sponsored by the ANS Power Division. It became of the highest attended Embedded Topical Meetings in ANS history. He also served on the ANS Power Division Program Committee and as a Session Organizer for many special sessions over the years. In 1993, Angelo was a candidate for the ANS Board of Directors and was appointed as the Vice Chair of the ANS Special Committee on New Construction by the Society president.
