{SG) channel head drain line weld, to assess the impact of a potential failure of other similar SG channel head drain lines. The evaluation concluded that a single high head safety injection pump could effectively provide emergency core cooling to mitigate the effects of a SG channel head drain line failure. This type of failure would result in Reactor Coolant system (RCS) leakage into the Containment and would be identified through routine Technical Specification RCS leakage surveillances and by containment gas and particulate radiation monitors. | 1009 Stopped power increase at 100%, 820 MWe. | ||
Therefore, an unreviewed safety question does not exist. Design Change Package (Safety Evaluation No. 90-195) | 09/24/93 1055 Started power reduction due to Steam Generator "C" level oscillations. | ||
This DCP also installed a new battery power supply system, including a charger with a constant voltage transformer to protect the charger from high voltage electrical spikes. These modifications increased the reliability of the nonsafety-related IA system. The automatic valves represent an IA system enhancement and perform the same functions as the manual valves. The new valves do not affect any safety-related system. Therefore, an unreviewed safety question does not exist. Temporary Modification | 1100 Stopped power reduction at 99%, 800 MWe. | ||
{Safety Evaluation No. 93-185) | 09/25/93 2133 Started power reduction due to Steam Generator "C" level oscillations. | ||
{TM) S1-93-11 installed electrical jumpers to bypass test switch 1-LC-495-TB on the Unit 1 Safety Injection (SI) system train "B" circuitry to allow its replacement without rendering the circuits inoperable. | 2138 Stopped power reduction at 98%, 792 MWe. | ||
This TM continued to allow SI system train "B" actuation on a valid signal and did not affect train "A", thus maintaining the design SI functions. | 09/30/93 2400 The reporting period ended with the Unit at 98% power, 792 MWe, due to Steam Generator "C" level oscillations. | ||
Double verification of jumper installation/removal and post maintenance testing were performed. | |||
Therefore, an unreviewed safety question did not exist. | e Surry Monthly Operating Report No. 93-09 Page 11 of 16 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: September, 1993 SE 93-184 Safety Evaluation 09-09-93 Safety Evaluation 93-184 was performed, following a failure of a Unit 1 "B" Steam Generator {SG) channel head drain line weld, to assess the impact of a potential failure of other similar SG channel head drain lines. | ||
The evaluation concluded that a single high head safety injection pump could effectively provide emergency core cooling to mitigate the effects of a SG channel head drain line failure. This type of failure would result in Reactor Coolant system (RCS) leakage into the Containment and would be identified through routine Technical Specification RCS leakage surveillances and by containment gas and particulate radiation monitors. Therefore, an unreviewed safety question does not exist. | |||

SUMMARY
OF OPERATING EXPERIENCE MONTH/YEAR: September, 1993 The following chronological sequence by unit is a summary of operating experiences for this month which required load reductions or resulted in significant non-load related incidents.
UNJI ONE:
09/01/93 0000 The reporting period began with the Unit operating at 81 % power, 600 MWe; high pressure heater drain pump level control valve, 1-SD-LCV-106, inoperable.
0737 Started power increase following maintenance on 1-SD-LCV-106.
0930 Unit at 100% power, 775 MWe.
09/30/93 2400 The reporting period ended with the Unit 1 at 100% power, 820 MWe.

SUMMARY
OF OPERATING EXPERIENCE MONTH/VEAR: September, 1993 UNIT Two:
09/01/93 0000 The reporting period began with the Unit heating up in preparation for start-up. (Reactor had tripped due to safety injection relay failure on 08/27/93) 09/03/93 0316 Unit on-line. Started power increase.
1519 Stopped power increase at 97.5%, 760 MWe. Holding for evaluation of Steam Generator "C" level oscillations.
09/04/93 0648 Started power reduction to maintain condenser vacuum while cleaning water boxes.
0650 Stopped power reduction at 90%, 715 MWe.
1624 Started power increase following water box cleaning.
1706 Stopped power increase at 97.5%, 760 MWe.
09/09/93 0630 Started power reduction to maintain condenser vacuum while cleaning water boxes.
0635 Stopped power reduction at 95%, 740 MWe.
1610 Started power increase following water box cleaning.
1635 Stopped power increase at 99%, 785 MWe.
09/13/93 0945 Started slow power increase.
1009 Stopped power increase at 100%, 820 MWe.
09/24/93 1055 Started power reduction due to Steam Generator "C" level oscillations.
1100 Stopped power reduction at 99%, 800 MWe.
09/25/93 2133 Started power reduction due to Steam Generator "C" level oscillations.
2138 Stopped power reduction at 98%, 792 MWe.
09/30/93 2400 The reporting period ended with the Unit at 98% power, 792 MWe, due to Steam Generator "C" level oscillations.
e Surry Monthly Operating Report No. 93-09 Page 11 of 16 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: September, 1993 SE 93-184 Safety Evaluation 09-09-93 Safety Evaluation 93-184 was performed, following a failure of a Unit 1 "B" Steam Generator {SG) channel head drain line weld, to assess the impact of a potential failure of other similar SG channel head drain lines.
The evaluation concluded that a single high head safety injection pump could effectively provide emergency core cooling to mitigate the effects of a SG channel head drain line failure. This type of failure would result in Reactor Coolant system (RCS) leakage into the Containment and would be identified through routine Technical Specification RCS leakage surveillances and by containment gas and particulate radiation monitors. Therefore, an unreviewed safety question does not exist.
DCP 86-03 Design Change Package 09-10-93 (Safety Evaluation No.90-195)
Design Change Package 86-03 replaced the manual bypass and isolation valves for the Unit 1 and 2 Instrument Air (IA) system dryers, 1/2-IA-D-1, with automatic {electro-pneumatic) valves. The new valves were installed to provide for timely automatic isolation of the IA system dryers in the event of a drop in pressure in the IA header downstream of the dryers. Specifically, the new valves are designed to allow automatic bypass and isolation of the IA dryers in the event the dryer's automatic blowdown feature does not function as designed. This DCP also installed a new battery power supply system, including a charger with a constant voltage transformer to protect the charger from high voltage electrical spikes.
These modifications increased the reliability of the nonsafety-related IA system. The automatic valves represent an IA system enhancement and perform the same functions as the manual valves. The new valves do not affect any safety-related system.
Therefore, an unreviewed safety question does not exist.
TM S1-93-11 Temporary Modification 09-20-93
{Safety Evaluation No.93-185)
Temporary Modification {TM) S1-93-11 installed electrical jumpers to bypass test switch 1-LC-495-TB on the Unit 1 Safety Injection (SI) system train "B" circuitry to allow its replacement without rendering the circuits inoperable.
This TM continued to allow SI system train "B" actuation on a valid signal and did not affect train "A", thus maintaining the design SI functions. Double verification of jumper installation/removal and post maintenance testing were performed. Therefore, an unreviewed safety question did not exist.
