3Q/08: Revision 3 of the GGNS PRA was issued on June 30, 2008. Revision 3 was a major update that included the update of plant specific data, initiator frequencies (both plant specific and generic), common cause analyses, human reliability analyses; the addition of several new initiators; and changes to the modeling of offsite power. The revision has resulted in a new overall core damage frequency, changes to the Fussell-Vesely importance of all of the MSPI related basic events and changes to the probability of many of the MSPI related basic events.
