A collaboration between the Department of Energy’s Office of Isotope R&D and Production and the Department of Commerce’s National Institute of Standards and Technology has recovered large quantities of radium-226—valued for its use in medical radioisotope production—from radiological waste stored at NIST facilities. Ra-226 is an important element in developing therapies for patients fighting cancer.

The Fukushima Daiichi accident highlighted the importance of risks from multiple nuclear reactor unit accidents at a site. As a result, there has been considerable interest in Multi-Unit Probabilistic Risk Assessment (MUPRA) and developments in the past few years. This panel discusses the status, related issues, and recent developments in MUPRA. Specifically, such topics as site risk metrics, risk aggregation, inter-unit dependency, and common cause modeling, safety goals, external event hazard and fragility treatments, industry, regulatory and international experiences in the context of MUPRA will be discussed. Panelists: M. Modarres, UMD (Chair); G. Apostolakis (NRRC); O. Coman (IAEA); F. Ferrante (EPRI); K. Fleming (KNF Consulting); M. Röwekamp (GRS)
