Production and release rate of Ar from the UT TRIGA Mark-II research reactor.

Air samples were taken at various locations around The University of Texas at Austin's TRIGA Mark II research reactor and analyzed to determine the concentrations of Ar, Ar, and Xe present. The measured ratio of Ar/Ar and historical records of Ar releases were then utilized to estimate an annual average release rate of Ar from the reactor facility. Using the calculated release rate, atmospheric transport modeling was performed in order to determine the potential impact of research reactor operations on nearby treaty verification activities.
