One rule of architectural design in one of my settings is the prime number rule: a building that abides by this rule can survive a 2-kiloton nuclear surface burst 300 meters away 5 times in a row while keeping the occupants safe. It's called the prime number rule because 2,3, and 5 are the first prime numbers. Don't laugh, weirder things have been come up with IRL.
In practice, no nuclear weapons in my setting reach the level of 2 kilotons, as nuclear detonations above 1 kiloton are forbidden by treaty, and generally result in the offender getting scrubbed off the map by everyone else's megaton-level missile forces, but corporate and the public both decided that the prime number rule was a snazzy quality-assurance kind of thing, and so it stuck.
One part of surviving a 2-kiloton surface burst at 300 meters is withstanding, according to NUKEMAP-2:
65,000 rem of radiation (neutron/gamma; alpha/beta radiation is nonexistent for the purposes of this).
17 psi of overpressure.
The 65,000 rem of radiation can be resolved, and I already have done that. However, my problem is the overpressure. I cannot find as many reliable sources regarding defense against overpressure.
What shape of construction most efficiently dissipates the energy from a 24-psi overpressure/shock wave?
Undergrounding the structure is not a viable option here; the area in question has a rather high water table, and the soil is heavily contaminated with perchlorates that would seep in and be detrimental to the structure's occupants, among other consideration. I need an above-ground structure, and I need to know its shape.
