OPERATIONS
SUMMARY
March 1997 The plant entemd the month operating at 100% power and remained at that power level for the remainder of the month. Net unit electrical output averaged approximately 820 MWe during March.
MAJOR SAFETY RELATED MAINTENANCE The major safety related maintenance items completed during the month involved the following equipment:
Auxiliary and Fuel Handling Building Fan AH-E-14C Repair of the Auxiliary and Fuel Handling Building Ventilation Exhaust Fan AH-E-14C was continued from last month. The work accomplished during March included completion of the fan / motor rigging assembly, installation of the fan blades onto the motor and test running /
balancing the fan assembly. Reinstaliation of the fan assembly into the duct is in progress and will continuein April.
Screen House Ventilation Fan AH-E-27B Screen House Ventilation Fan AH-E-27B was removed from service because the unit was.
becoming noisy. Investigation revealed that the pillow block bearings were worn and required replacement. New bearings were installed and AH-E-27B returned to service.
1 Beactor Buildine Fan AH-E-1 A Reactor Building Ventilation Fan AH-E-1 A was removed from service after the unit tripped two times. The unit was meggered and bridged from the MCC with unsatisfactory results. A physical-inspection was made and 'T' lead connector (A6) to spark plug connection was found burned causing the unit to trip. Connector A6 and the corresponding spark plug was replaced. All other electrical connections were cleaned and tightened. All testing was found to be satisfactory and AH-E-1 A returned to service.

i REFUELING INFORMATION REOUEST
- l. Name of Facility: Three Mile Island Nuclear Station, Unit 1 2.
Scheduled date for next refueling shutdown: September 5,1997 3.
Scheduled date for restart following current refueling: NA i
- 4. Will refueling or resumption of operation thereafter require a technical specification change or other license amendment? Yes. To support GPU Nuclear's independent reload analyses for Cycle 12 as discussed in response to Question 6 below, T.S. 6.9.5.2 will require revision to include references to the GPU Nuclear analysis methods applied to the reload.
- 5. Scheduled date(s) for submitting proposed licensing action and supporting i
information: A Technical Specification Change Request for the changes as discussed above will be submitted once the GPU Nuclear topicals are approved.
6.
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, new operating procedures:
a) GPU Nuclear Letter 6710-96-2092, dated March 28,1996 confirmed plans to perform independent reload design evaluations for Cycle 12, the next operation cycle, based on NRC approved methods described in GPU Nuclear Topical Reports TR-091-A (core physics), TR-087-A (core thermal hydraulics), TR-078-A (FSAR safety analyses) and TR-092P-A (design and setpoints methodology) submitted to the NRC. The NRC has approved all of the associated topical reports.
The GPU Nuclear Cycle 12 reload program and results are expected to be available for NRC review in the May to June 1977 time frame.

b) Cycle 12 fuel rod performance calculations (e.g. internal pin pressure) j will be performed by Framatome Cogema Fuels Company (FCF) using the approved TACO 3 (BAW-10162P-A) and GDTACO (BAW-10184P-A) fuel codes. Results require minor changes to the Mark B9 fuel rod design (lower i
fill gas prepressure, increased plenum volume). The new design will meet all fuel criteria in the latest approved revision of BAW-10179P-A, Safety Criteria and Methodology for Acceptable Cycle Reload Analyses. Fuel rod cladding corrosion calculations for all Cycle 12 fuel are being done by FCF using the COROS2 methodology now under review by the NRC. Approval is expected soon. The TACO calculations are being done using power histories generated with the GPU Nuclear approved core physics codes CASMO-3/ SIMULATE-3 (TR-091A). Use of the SIMULATE-3 power l
peaking uncertainty of 5.5% with the TACO methodologies, rather than the current FCF NEMO physics code (BAW-10180A, Rev 1) uncertainty of j
4.8%, was approved by NRC on October 4,1995 for application to TMI-1 i

The present licensed capacity is 1990. Phase I of the reracking project to increase spent fuel pool storage capacity permits storage of 1342 assemblies.
Upon completion of Phase II of the reracking project, the full licensed

capacity will be attained. Phase It is expected to be started in 2002.
- 9. The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity:

Completion of hase.I of the reracking proiect permits full rnre nmload (177 fuel assemblies) through the end of Cycle 14 and on completion of the rerack project full core off-load is assured through and beyond the end of the current operating license.
