09/18/2006 UCS documented the factors leading to the year-plus reactor outage that began in September 1996 in this case study for our Walking a Nuclear Tightrope report. Download the pdf >

04/12/2006 UCS expressed concerns to NRC Region III that operators intentionally disabled emergency systems during February 2006 event for the wrong reasons, just as operators at Three Mile Island Unit 2 and Chernobyl Unit 4 had done to transform relatively minor events into nuclear disasters. Download the pdf >

02/21/2006 UCS explained an event in which the reactor was shut down and a Site Area Emergency declared, for only the third time in U.S. nuclear plant history. Download the pdf >
