They also wanted these for domestic use. No fallout means making a new Panama Canal, or removing a pesky mountain, are just nuclear construction projects.
Yeah... the problem is if you were to use them for excavating, you have to explode them on, in, or near the ground which will generate lots of fallout from neutron irradiation of the ground materials.
Clean H-bombs are only clean if used for air bursts, but air bursts aren't effective for excavation.
