Blast doors from around the world

[T. Brown 1st MRB]

One of the blast doors from the NORAD Cheyenne Mountain complex. Roughly 25tons, they are located 1/3 of a mile within the mountain.

The blast doors to the BigRIPS accelerator in Tokyo. That link there is essentially the user manual to the beam factory; a slightly-less technical explanation is here.

The blast door for Culham Centre for Fusion Energy in Oxfordshire.

Post more if you know of 'em! I came across the NORAD picture while researching and decided to see what others I could find, and having visited the site in Tokyo, trust me when I say these pictures do not do their immense size and sense of weight justice.

Cheyenne Mountain and Blast Door can only mean one thing for me.

Here's a rather cool one. Not entirely sure how it opens.

Oh, it's Browns Ferry Nuclear Plant by the way

Nuclear launch control room door

Actually, I don't understand why all these nuclear emergency doors aren't designed to be slammed by gravity or the pressure wave if they are open during a blast.

Can't believe I missed my own nuclear power plant one : )
