Andrew Wysong (LANL Division Leader – Nuclear Criticality Safety) giving presentation on nuclear criticality safety topics at LANL to Nuclear Engineering undergraduate students participating in the program

In collaboration with Los Alamos National Laboratory (LANL)

Program organizers: Dr. Pavel Tsvetkov and Dr. Sunil Chirayath

This program presents the fundamentals and importance of nuclear criticality safety with respect to nuclear R&D operations, exposing students to the criticality safety discipline and helping prepare them for a future career in the field.

The program is designed to create a pipeline of nuclear criticality safety engineers to U.S. national laboratories and industry. Initiated with support from Los Alamos National Laboratory (LANL), participating students are encouraged to apply for an internship at LANL’S Nuclear Criticality Safety Division.
