Term Name:	nuclear polyadenylation-dependent rRNA catabolic process
Synonyms:	nuclear poly(A)-dependent rRNA catabolic process
Definition:	The chemical reactions and pathways occurring in the nucleus and resulting in the breakdown of a ribosomal RNA (rRNA) molecule, including RNA fragments released as part of processing the primary transcript into multiple mature rRNA species, initiated by the enzymatic addition of a sequence of adenylyl residues (polyadenylation) at the 3' end the target rRNA.
