03/12/94, 4th refueling.
Scheduled date for restart following refueling.
05/31/94.
Will refueling or resumption of operation thereafter require a Technical Specification change or other license amendment?
At present, two Tech. Spec. changes are in process.
One for increasing the radially averaged weight percent of U235 in fuel rods to 4.30%.
The other is to change the DNBR setpoint limitfrom 1.24 to 1.30. These are generic Tech. Spec. changes, and willbe implemented on a Unit by Unit basis, beginning with U3C5.
Scheduled date for submitting proposed licensing action and supporting information.
Started in July 1993.
Important Licensing considerations associated with refueling, e.g., new or different fuel design or supplier, unreviewed design or performance analysis
- methods, significant changes in fuel design, and new operating procedures.
U3C5 will incorporate a new higher maximum enrichment level of 4.30% U235 and will also utilize a new integral burnable absorber, Erbium.
The NRC granted a license amendment (No. 35) which allows the use of 80 fuel rods clad with advanced zirconium based alloys (other than Zircaloy<) in two fuel assemblies during Unit 3 Cycles 4, 5, and 6 for in-reactor performance evaluation.
