Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.
Nuclear Criticality Safety Division 2025 Conference
DOE Nuclear Criticality Safety Program (NCSP)
Manager
Dr. Angela Chambers is the DOE Nuclear Criticality Safety Program (NCSP) Manager since November 3, 2016. She began her career at the Portsmouth Gaseous Diffusion Plant serving in the project management, decontamination and recovery, nuclear criticality safety, and non-destructive assay groups. Angela was a technical staff member and program lead for Los Alamos National Laboratory for 11 years, working for the Probabilistic Analysis Group and then for Weapons Systems Engineering where she had assembly design responsibility for the W78 and W88 systems. She has been involved with Nuclear Explosive Safety since joining NNSA in 2009 and was responsible for NES oversight and the DOE NES directives. Angela retired from the US Air Force Reserves where she instructed military and civilian first responders on nuclear and radiological incidents and the use of radiation detection instrumentation for DoD’s Defense Threat Reduction Agency. Angela earned her doctorate in nuclear engineering from the University of Texas at Austin. She holds a Master of Science degree in nuclear engineering and a Bachelor of Science in physics, both from the Ohio State University. Angela has two daughters: Trinity and Tristan Ivy-Mike
