Scheduled date for restart following refueling.

06/07/94.

Will refueling or resumption of operation thereafter require a Technical Specification change or other license amendment?

At present, four Tech. Spec. changes are in process.

One for increasing the radially averaged weight percent of U235 in fuel rods to 4.30w/o. 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.

Also, there are two other Tech. Spec. changes that will allow U3C5 to operate at 100% power due to the steam generator issues.

Scheduled date forsubmitting proposed licensing action and supporting information.

The fuel enrichment change was submitted in October 1993 and the DNBR setpoint change was submitted in January 1994.

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 4.30w/o 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 Zircaloy4) in two fuel assemblies during Unit 3 Cycles 4, 5, and 6 for in-reactor performance evaluation.

Date of issuance was July 20, 1992.
