How could a nuclear reaction possibly happen at room temperature? We know how other blasts work and what chemicals are used to cause their effect, but what chemicals could cause a nuclear reaction at room temperature or containable? It sounds like it would be the opposite of what causes them to go boom!
No chemical reaction can have any significant influence on the rate of nuclear reactions. The valence electrons have such a low probability of being actually in the atomic nuceus (zero for p orbitals, and virtually zero for s,.. orbitals, because the core is so small) that no interaction is observed. It a different story for inner electrons of heavy elements, but those are not much influenced by chemistry.
I'm not sure if a tiny variation of the half life of certain decays is measurable for different chemical states. But to really change something, let alone cause a fusion reaction, is totally impossible.
(Update: The website reference by Ian below gives biggest changes of halflife of less than one percent for Be-7, and less for a few other cases. As could be expected, electron capture decays are most sensitive. Removing inner electrons of heavy elements can make huge changes.)
