[sarah_]

uh, have an assessment task on thursday. so...i need to identify some of the problems which Fermi and his team needed to consider before beuilding the first nuclear reactor. i'm sure the answer is easy as, but i'm not really sure what i'm looking for and plus i'm a dumb-ass.
thanks guys.

How to prevent an excessive reaction from occuring (ie to stop it getting out of control), they ended up having a man with an axe ready to cut ropes holding cadmium rods which would absorb the neutrons.

How to take care of the graphite dust caused during the construction, the pile was built inside an airtight square balloon which was deflated when they finished the construction.

Any possible radiation (considering it was under a football field in the University of Chicago).
