REFUELING INFORMATION DOCKET NO. ~29 UNIT NAME MbLikR2 DATE 93LQSLR4 COMPLETED BY EMMY~

Scheduled date for next refueling shutdown.

The 5th refueling outage is tentatively scheduled for 09/17/94, however, it is more likely to take place in the first quarter of 1995.

Scheduled date for restart following refueling.

12/06/94, or 80 days following the new refueling shutdown date.

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

A change may. be required to Technical Specification 3.9.6 to raise the overload cutoff limit to accommodate the new fuel assembly modification. Also, Technical Specification Section 6.9.1.10 will be modified to add the new Inlet Flow Distribution methodology.

Scheduled date for submitting proposed licensing action and supporting information.

10/13/94.

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.

The fuel assembly will consist of a denser fuel pellet, Erbium burnable absorber and guardian grid. A primary temperature drop of 10' is currently planned.

03/19/94, 4th refueling.

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 limit from 1.24 to 1.30. These are generic Tech. Spec. changes, and will be 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 for submitting 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.gnew 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 Zircaioy<) in two fuel assemblies during Unit 3 Cycles 4, 5, and 6 for in-reactor performance evaluation. Date of issuance was July 20, 1992.
