Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

A vacuum vessel wall with a postulated crack is modeled by using the two-dimensional solid finite elements. The J-integral value, a criterion of fracture mechanics, is calculated to estimate the integrity of the vacuum vessel wall with a postulated crack.
The analytical results show that the J-integral value of a crack having a quarter depth of the wall width is considerably less than the fracture toughness JIC when the membrane stress is less than the 0.2% proof stress of the unirradiated material, even if the vacuum vessel is irradiated to 3 dpa. This means that a shallow crack in the vacuum vessel wall does not become critical in the design load.
