Unit 2 was placed on administrative hold to r'esolve various TVA and NBC concerns. The unit was shut down for its fifth refueling outage on September 15, 1984, with a scheduled restart date of January 22, 1986.. This refueling involves loading additional 828E (retrofit) assemblies into the core, finishing torus modification, turbine inspection, piping inspection, TNI-2 modifications; postaccident sampling facility tie-ins, core spray change-out, and feedwater sparger inspection.

There were no assemblies in the reactor vessel. At month end, there were 273 new assemblies, 764 EOC-5 assemblies, 248 E0C-4 assemblies, 352 EOC-3 assemblies, 156 EOC-2 assemblies, and 132 ROC-1 assemblies in the spent fuel storage pool. The present available capacity of the spent fuel pool is 77 locations. All old racks have been removed from the pool and new HDEs are being installed.
