Performed ' shutdown using remote shutdown panel.
While shutdown performed repairs to reactor Recirculation Motor Generator Set A.
November November 2, forced shutdown - 694.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />.
I Shutdown to repair the cause of excessive air in -
leakage into the condenser.
Outage scope was expanded to include installation of new relief valves to prevent future overpressurization of the condensate return line.
On November 17, overpressurization of this line caused an ' expansion joint to rupture and damaged a penetration in the Condensate Storage. Tank.
Reported as LER 86-045 transmitted January 12, 19 87 by NP 870025.
December December 1, forced shutdown - 710.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />.
l Continuation of outage that began November 2.
2.3 Fuel Performance The initial startup of the year occurred on August 4, 1986 following a ten-month outage.
Since then, the reactor has achieved criticality ten times and has i
generated approximately 72 MWD / ton of thermal energy.
I The current core average exposure is approximately 100 MWD (t)/ ton.

The daily average thermal power exceeded 5% on only 19 days.
The 20% limit was-exceeded ' once during a.brief pressure transient.
Maximum power was estimated to be 22%.

S. NRC Regulatory Guide 1.16, the Detroit Edison I.
. Conpany-submitted the Annual Oper ating. Repor t for the Fermi L
2 Nuclear Power Plant for the period of January 1,1986 through December. 31, 1986.
The report was. transmitted via GP-87-0007 dated February 27, 1987.
Section 2.2 " Summary of Outages and Forced Reductions Greater than 20 percent of Full Power" has been revised.
[
This section originally reported the outages based on hours L
reactor was shutdown.
The' outages are now based on hours f
the generator was offline.
I If you have any questions or comments regarding. this revision to the report, please contact Mr. Girija Shukla at (313) 586-1617.
