. NRC-97-0017 Page 3 l.0 Introduction The Fermi 2 Nuclear Power Plant site is located on the western shore of Lake Erie in Frenchtown Township, M'onroe County, Michigan. The Nuclear Steam Supply System is a -

General Electric BWR 4 with a Mark I pressure-suppression containment. The plant is fully owned by the Detroit Edison Company. '

2.0 Summary of Operations 2.1 Summary of Operating Experience Fermi 2 was operating at 96 percent power at the start of 1996. The fifth refueling outage (RF05) commenced on September 27,1996 and was scheduled to be completed on November 19,1996. However, due to emergency diesel generator, safety relief valve position indication, and vacuum breaker closed position indication problems the l plant was stillin RF05 at the close of 1996. During 1996, with the reactor critical, the )

reactor automatically scrammed once on December 28,1996, due to a false Level 3 signal while valving in the reactor water level reference leg backfill system during i startup from RF05. There was one forced outage due to a Technical Specification required shutdown when both divisions of Emergency Equipment Cooling Water (EECW) were declared inoperable due to a make-up tank design issue. A plant modification was installed and the plant was restarted on April 19,1996. During this startup, the high pressure core injection (HPCI) and reactor core isolation cooling (RCIC) systems were declared inoperable due to surveillance test requirements not being satisfied, and a Technical Specification shutdown was required. There were eleven reactor power reductions for turbine generator related repairs, surveillance testing, and control rod pattern adjustments. Core Thermal Power (CTP) is .

administratively limited to 96 percent due to turbine and steam piping vibration limitations.

2.2 Summary of Outages and Forced Reductions Greater than 20 Percent of Full Power January 19,1996 - Power Reduction Reactor power was reduced to 55% CTP to perform scram pilot solenoid valve maintenance, scram time testing, control rod pattern adjustments and main turbine stop and control valve surveillances.  ;

February 10,1996 - Power Reduction I i 1

2.3 Fuel Performance The reactor was operating in Mode 1 at the start of 1996. During 1996 the plant produced about 221 effective full power days based on a 3430 MWt rating. During 1996, Core Thermal Power (CTP) was administratively limited to 96 percent due to turbine limitations.

Fermi 2 began 1996 with one leaking fuel bundle in the core, which had already been suppressed by three control blades, and a sum-of-six offgas activity at the steam jet air ejector of about 120 Ci/sec. On March 16 offgas activity temporarily spiked and the spike peaked at about 600 pCi/sec. Analysis ofdata could not rule out the possibility of a second leaking fuel bundle, and a power suppression test was performed.

The test confirmed a second leaking fuel bundle, and two more control blades were fully inserted to suppress power in this bundle. All five suppressor blades remained fully inserted until the end of cycle, at which time the sum-of-six off-gas activity was about 500 pCi/sec.

General Electric performed vacuum sipping during RF05, and confirmed two leaking bundles which both were in suspect cells containing suppressor control blades. The first leaking bundle, which failed in October 1995, was bundle .ABB002 which is a thrice burned ABB bundle. The second bundle leaking bundle was YJ2624, which is a twice burned GElI bundle. ABB002 was suppressed for about eleven months, and YJ2624 was suppressed for more than four months. Based on offgas activity and coolant sampling, both bundles showed no evidence of significant degradation of the leaking fuel rods. Both bundles were discharged in RF05, and analysis to determine the cause of the leakers is scheduled for 1997, 2.4 Shore Barrier Survey A survey of the Fermi 2 shore barrier was completed as required by Technical Specification 4.7.3. The results of the survey indicated no damage, significant movement, or deterioration of the barrier. All forty-seven survey point elevations were within the tolerance specified in Technical Specification Table 3.7.3-1. Civil Engineering Drawings 6C721-44 through 49 were revised to incorporate the survey data. No unusualincidents occurred in 1996 that would have required additional surveillances.

There were no instances in 1996 where an SRV actuation was demanded by an automatic logic system. SRVs were manually actuated for surveillance testing or post-modification testing as described below:

. 2.7 Service Life of Main Steam Bvoass Line In accordance with a Detroit Edison letter to the NRC dated November 7, 1986 [VP-86-0154], the cumulative time the main steam bypass lines are operated with the bypass valves between 30 percent and 45 percent open will

,! be reported annually. A cumulative value of 100 days is not to be exceeded j without prior NRC notification.

i Evaluations performed by Stone and Webster and by Hopper and Associates

concluded that the bypass lines are acceptable for safe operation when j operated within the 100 day constraint. Based on these evaluatioris, the new main steam bypass piping that was installed in 1985 has a service life which will allow it to function for the life of the plant under anticipated operating conditions. The main steam bypass lines cumulative usage was 36.36 days as
of December 31,1996.

2.8 Specific Activity Analysis of the Primary Coolant Exceeding the Limits of Technical Specification 3.4.5 During 1996, the specific activity of the primary coolant did not exceed the  !

limits of Technical Specification 3.4.5.

1 2.9 ECCS Coolina Performance Evaluation Model Channes or Errors During the preparation of the 1995 Fermi 2 Annual Operating Report, Detroit Edison determined that the ECCS evaluation model change reporting section of the annual report had not been included in previous Annual Operating Reports, from 1989 through 1994, as required by Fermi 2 plant procedures.-

Detroit Edison believed that the vendor letters to the NRC satisfied the 10 CFR 50,46 reporting requirements.

In July 1991, as part of the Fermi 2 Power Uprate Program, the SAFER /GESTR-LOCA Loss-of-Coolant Accident Analysis was performed.

This analysis provides a baseline of 1602 degrees Fahrenheit where the impact of any previous change or error notices would have been already considered.

On April 25,1996, Detroit Edison confirmed with General Electric that the total accumulation of peak clad temperature (PCT) changes or errors identified as being applicable to Fermi 2 since July 1991 was 65 degrees Fahrenheit. This 65 degrees Fahrenheit change meets the notification requirements per 10CFR50.46(a)(3)(ii) because the change in PCT is greater than the thirty day reporting threshold (50 degrees Fahrenheit) for the accumulation of the absolute magnitude of changes or errors in the evaluation models or their application, and was reported to the NRC on May 28,1996 (Detroit Edison Letter No. NRC-96-0052).

o {

j $ ( Enclosure to NRC-97-0017 1 Page 10 l 1 After adding the 65 degrees Fahrenheit to the licensing basis PCT determined

) in the 1991 SAFER /GESTR analysis, there is still more than 500 degrees

, Fahrenheit of margin to the 2200 degree Fahrenheit limit specified in 10CFR50.46. The resulting PCT is still well below the temperature range where cladding oxidation and hydrogen generation becomes significant.

Therefore, the core-wide metal-water reaction and maximum local oxidation 3 remain well within the 10CFR50.46 limits. Also, the statistical upper bound PCT of 1351 degrees Fahrenheit plus the 65 degrees Fahrenheit change remains well below the 1600 degrees Fahrenheit limit specified in the NRC acceptance of the SAFER /GESTR methodology.

l 2.10 ECCS Outages Pursuant to Fcrmi 2 Technical Specification 6.9.1.5.c, a summary of the Emergency Core Cooling System (ECCS) outages which occurred between January 1,1996 and December 31,1996 is provided. The tabulation of ECCS outage hours (Table 2.10-1) includes both forced and planned outages for the Low Pressure Coolant Injection (LPCI), Core Spray, HPCI, and Automatic -

Depressurization Systems (ADS). An outage was considered to be whenever one of the ECCS systems was out-of-service at a time it was required to be operable per Technical Specifications.
