WebMar 24, 2024 · The NRC requested that the Georgia Power Company (GPC or licensee) perform a detailed survey of all torus anchor bolts in the E. I. Hatch Plant, Units 1 and 2, and determine the extent of bolt distortions. The licensee found 190 bolts in Unit 1 bent from 1/8 inch to 1 inch, with 45 of the bolts bent in excess of 1/2 inch. The BWR concept was developed slightly later than the PWR concept. Development of the BWR started in the early 1950s, and was a collaboration between General Electric (GE) and several US national laboratories. Research into nuclear power in the US was led by the three military services. The Navy, seeing the possibility of turning submarines into full-time underwat…
