SUMMARY

OF UNIT I OPERATI!!G EXPERIENCE-MARDI 1980  ;

I 3/1 At the beginning of this reportino period Unit I was operating l I

at 730 We with the reactor at 85% power, while conducting core physics measurenents to verify that the power distribution anomaly had been rectified. At 1125 reduced load to 600 We due to loss of #11 steam generator feed pump from erroneous  :

actuation of fire system deluge. At 2132 the reactor tripped due to loss of condenser vacuum when all six circulating water 3 pumps tripped due to a salt water leak sprayino on the f circulating water room high water level protective circuitry.  :

i 3/2 The reactor was brought critical at 0510 and the unit t paralleled at 0715. Load was increased to 730 ftWe at 2030.

3/6 Increased load to capacity (850 f4fe) at 2300.  ;

I 3/10 Decreased load to 835 We to repair a steam leak on 15B '

feed water heater.

3/11 Resumed full loaa operation (860 MWe) at 2200.  !

3/20 At 2130 load was reduced to 700 fS!e to investicate salt water leakage into the main condenser.  ;

3/21 After plugging one condenser tube resumed full load operation (855 MWe) at 1200.

3/22 Decreased load to 710 MWe to clean condenser water boxes at l 1830. ,

3/23 Increased load to capacity (855 MWe) at 1430. 1 3/25 At 0850 the reactor tripped due to voltage instability on the '

^

reactor trio bus caused by #12 motor generator set. At 2030 the reactor was brought critical and the unit paralleled at 2316.

SUMMARY

OF UNIT I OPERATING EXPERIENCE-MARCH 1980 3/26 At 0127 during startup the reactor tripped at 15% power on high axial flux offset due to control rods being inserted for previous power swings. The reactor was brought critical '

at 0350 and the unit paralleled at 1104.

3/27 Resumed full load operation (850 MWe) at 1600. At 2319 load r

was decreased to 755 MWe to investigate salt water leakage

^

into the main condenser. I i

3/23 Increased load to capacity (850 MWe) at 1655 after pluaging ,

one condenser tube. At 2110 decreased load to 765 MWe to investigate salt water leakage into the main condenser. ,

r 3/29 Resumed full load operation (850 MWe) at 2130 after plugaing one condenser tube.

3/30 Load was decreased to 840 MWe at 2100 for variable Tave P

testing.

3/31 Increased load to capacity (865 MWe) at 2300. At the end of this reporting period Unit I was operating at 865 MWe with the reactor at 100% power. >

SUMMARY

OF UNIT II OPERATING EXPERIENCE-MARCH 1980 3/1 At the beginning of this reporting period Unit II was operatina at 900 MWe with the reactor at 100% power.

3/2 Decreased load to 765 MWe at 1100 due to ice forming on the .

intake traveling screens. Resumed full load operation s

(900 MWe) at 2030.

3/11 At 1000 load was reduced to 860 MWe for physics testing.

3/13 Increased load to capacity (900 MWe) at 2100.

3/14 Decreased load to 645 MWe due to control problems on #21 & 22 ,

steam generator feed pumps at 1300.

3/17 Resumed full load operation (905 MWe) at 1200.

3/22 Decreased load to 640 MWe at 0730 for maintenance on #22  :

steam generator feed pump.

3/23 Increased load to capacity (910 MWe) at 0200.

3/31 At the end of this reporting period Unit II was operating at 910 MWe with the reactor at 100% power.
