Question: It's 2016, but for some reason, the Cold War never ended. You've been inspired by your (for some inexplicable reason) favorite movie, Indiana Jones 4, to start a new business: building refrigerators. However, the market is so saturated that in order to distinguish yourself with a nice marketing campaign, you decide to make them **NUKEPROOF!** 

The refrigerator should be:

1. Usable as a real refrigerator would be.
2. No bigger than standard double door refrigerator, so no room-sized walk-in refrigerator. Though, you *can* add some additional size for additional armor, for example, in **reasonable** margins, so nothing like 10 meters of iron from one side.
3. Protect one person from up to 1.2 megatonnes of a TNT nuke at a minimum distance of 2 km from the explosion.

How are you going to design it and what materials are you going to use?

Answer: 
It's George Lucas's marketing manager here. We are now working on a new Indiana Jones movie: Indiana Jones and the Blastproof Fridge, where Indiana Jones goes for a quest to find the sacred Superfridge, made by God himself. We're now developing a new blastproof fridge, which will not only be used in our movie, but also put into sale. Here's how it looks like inside:

Notes: 

* the water is accessible from the food storage
* the oxygen is stored in liquid/solid state, at around 30K. This provides a cooling feature on top of all - cold air circulates from the tanks (if it melts from heat inside the fridge) to the fridge, and then back through the air filter.
* The cushioning would be ideally made from polystyren, because it also isolates the inside (but that's for a 10% surcharge)

Hope this helped will get us some money!
Your customers will need to:
Put your fridge underground in the cellar;  

Reinforce the cellar walls to withstand the shockwave of the blast and the collapse of the house on top. 

Add shielding in 2 layers, preferably tungsten, 0.5" each layer, since lead is just messy, on the outer side of the body, and on the inside, just behind the fibreglass interior. Put the insulation in between the two layers of tungsten. The piping and wiring to the outside from the inner compartment should leave through the bottom of the fridge.  

Recommend buyers get **TWO** fridges, or one for every member of the family and a spare for actually keeping food in.
