We have a completely uniform, hollow sphere made of high-strength steel. Inside this sphere a Tsar Bomba (RDS-220) is detonated. How thick (ballpark figure) would the sphere need to be to withstand the detonation without the outer surface being breached?
Some key values that may or may not be relevant:
- Blast yield: 210 PJ (50 megatons of TNT, from the wikipedia page)
- Diameter of the hollow space inside the sphere: 8m (just enough to fit the length of the bomb, from the wikipedia page)
- Steel: I'm not sure which parameters are neccessary, but as a start I'm gonna post the data sheet of Strenx 1300. Any other high-strength steel is fine too, in case some important data is missing on this specific one.
