Why momentum is conserved in nuclear reaction?

Momentum is *always* conserved. It is a direct consequence of the translational invariance of space (the laws of physics do not depend on location). Landau and Liftshitz, Classical Mechanics provides a derivation for, well, classical mechanics. Einstein generalized the notion for special relativity. L&L may cover that to. Sorry other folks, you've been snookered by teach. Momentum conservation is not a primative notion, but derived from the above basic symmetry.

Is there a reason why it shouldn't be? I mean isn't that like asking why momentum is conserved when two pool balls strike each other?

'because it is' is about as good an answer as you'll get.
conservation laws are about as airtight a law as you'll get.
why wouldnt it be conserved?! what sense would it make for momentum to disappear?

i think of using "conserved" on your question became probable no longer the main suitable notice. each and every thing is conserved, perhaps you meant what's replaced to the nuclear textile after the reacion happens. i think of it rather is termed transmutation
