Gundersen also translates from "Nukespeak" into plain English the Ft. Calhoun "event report" about a fire that cut power to cooling pumps in the high-level radioactive waste storage pool, resulting in the water's heat up at a rate of 2 degrees per hour. Eventually, the pool could have boiled dry, and the high-level radioactive waste could have caught on fire, had not the circulation pumps been restored. Pools are not considered safety significant by the U.S. Nuclear Regulatory Commission, so backup power is not required. Also, pools are not located within a primary containment structure, so potentially catastrophic releases of radioactivity would be released directly into the environment.
