This review was initiated to determine if the Nuclear Power Group (NPG) and Coal & Gas Operations (C&GO) were effectively managing critical spare parts.We found critical spare parts could be managed more effectively. We found there were inconsistencies in TVA's management of its critical spare parts.

Because of the importance of a reliable transmission system, the OIG audited the risk of significant equipment failure in the Energy Delivery (ED) organization.
