Physics Division Seminar, Friday, August 13, 2:00 in 6008 Auditorium. Canadian Plans for the Production of the Medical Isotope 99Mo W.T. Diamond (Recently retired from Atomic Energy of Canada Limited) Abstract The National Research Universal (NRU) reactor was shut down with a heavy water leak on May 15, 2009, and is just getting set to restart this August. The NRU reactor provided typically 40 to 50% of the world supply of the medical isotope 99Mo, used in approximately 80% of all medical procedures that use radioactive tracers. A number of activities followed that shutdown. In late May 2009, an Expert Review Panel on Medical Isotope Production was commissioned by Natural Resources Canada (NRCan), the government department responsible for Atomic Energy of Canada (AECL). The panel reported in November 2009, and the Canadian government responded to the panel during March 2010. A formal program, the “Non-Reactor-Based Isotope Supply Program” (NISP) was announced June 2, 2010, supported by a $35 million budget. This program requested proposals on electron-linac-based production of 99Mo or direct-production of 99mTc using a cyclotron and explicitly excluded any support for a new isotope reactor. This talk will review these events and then describe the two proposals. Dr. Diamond is a proponent of the electron linac program and will provide additional details on that proposal.
