RAC presented a 5-day training course on environmental risk assessment to Nuclear Regulatory Commission (NRC) staff from April 27 through May 1, 2015, at the NRC Professional Development Center in Rockville, Maryland. John Till, Helen Grogan, Peter Shanahan, Art Rood, and Justin Mohler presented lectures during the week, and the course was very well received. The course was designed to allow participants to use the acquired knowledge for performance evaluations of licensee environmental assessments, performing environmental impact reviews, inspecting licensee programs, and managing environmental projects. RAC is contracted to present up to four more training courses for the NRC through 2019.
