What does TUUM stand for?

What exactly are "magic points"

What is CIRA

Could an underwater swimmer survive that deep without being crushed by the weight of the water.

The accuracy of a submarine-launched ICBM is determined by several factors, one of which is the precision to which the submarine's own position is known at the time of launch. Submarines can't detect GPS while underwater and the errors in the boat's inertial navigation system have a noticeable effect. One solution is to go to place (such as a seamount) whose position has been mapped to high precision and stored in a database in the submarine. While not necessary, the use of a 'magic point' will noticeable improve the accuracy of the missile launch.
