In EGA IV2, Def. 3.2.4, Grothendieck defines a quasicoherent sheaf over a locally Noetherian scheme to be "irredondant" if it has a unique associated point. Presumeably, a module over a Noetherian ring is irredondant if it has a unique associated prime. However, googling gives no relevant results for "irredundant sheaf" or "irredundant module" (which I can understand, since it is rather a peculiar name).
