Nuclear Outage Performance

This review was initiated to assess recent efforts by the TVA Nuclear Power Group (NPG) to improve outage performance. The objective of the OIG's review was to determine whether the initiatives implemented by the NPG to improve outage performance achieved planned results and current improvement efforts can be improved. We found cost structure development and controls initiatives improved outage performance with respect to cost; however, outage duration and dose continue to miss business plan goals. Additionally, we found outage performance initiatives continually changed and excellence/improvement initiative plans did not include all planned actions. While some initiatives have been completed, others are ongoing and have rolled over to different plans, making it a challenge to tie changes to measurable results.
