' Docket No. 50-346 LICENSEE: Toledo Edison Company FACILITY: Davis-Besse Unit No. 1
SUBJECT:
AUXILIARY FEEDWATER (AFW) RELIABILITY ANALYSIS MEETING, OCTOBER 16 AND 17, 1985 Introduction We met with the licensee to discuss the status and results of AFW Reliability Analyses. Copies of the view graphs are provided in Enclosure 1. Enclosure 2 presents the proposed outline of the reliability analysis report. This was a follow-on meeting to the one conducted on September 25, 1985 at the Davis-Besse site. The meeting was attended by:
TED IMPELL CORP. NRC S. Jain S. Mitra C. McCracken C. Minge A. El-Bassioni J. Ridgely F. Rosa Discussion The licensee presented a summary of their AFW unavailability results (see last two pages of Enclosure 1). Additionally, they stated that the AFW reliability results would be docketed by October 25, 1985. For a loss main feedwater event, the licensee predicts an unavailability ofs 8x10-5 for the modified AFW system, allowing for operator action to start the new motor driven feed pump. The staff requested that justification be provided for each of the assumptions in their analysis.
To evaluate single failure vulnerability of the SFRCS, the staff requested a block diagram failure modes and effects analysis (FMEA). The licensee committed to provide this analysis by October 25, 1985.

AUXILIARY FEEDWATER OVERVIEW
. TWO 100% CAPACITY STEAM DRIVEN PUMPS
. CAPABILITY TO PF] VIDE MOTIVE STEAM TO AUXILIARY FEED PUMP TURBINES F".0M EITHER STEAM GENERATOR
. CAPACITY TO AL'f;N AUXILIARY FEED PUMP DISCHARGE FLOW TO EITHER STEli GENERATOR
. SAFETIGRADEINITIATIONBYTHESTEAMANDFEEDWATER
. RUPTURE CONTF JL SYSTEM
. SAFETY GRAD! STEAM GENERATOR. LEVEL CONTROL SYSTEM i
. TRAIN 1 MOV'S ARE DC POWERED i l TRAIN 2 M0V'S ARE AC POWERED l _
NORMAL SUCTION ALIGNED TO CONDENSATE STORAGE TANKS.
AUTOMATIC TRANSFER TO SAFETY GRADE SERVICE WATER SYSTEM ON LOW SUCTION PRESSURE l
l AUXILIARY FEEDWATER INITIATION THE SFRCS WILL INITIATE AFW UNDER THE FOLLOWING PLANT CONDITIONS: !
. 1. LOW STEAM GENERATOR LEVEL
- 2. HIGH STEAM GENERATOR LEVEL
- 3. HIGH STEAM GENERATOR TO MAIN FEEDWATER DIFFERENTIAL PRESSURE

e 8 9 PLANNED MODIFICATIONS TO RESOLVE HISTORICAL CONCERNS REPLACE WOODWARD PG-PL GOVERN 0R ON AFPT #1 WITH A WOODWARD PGG MODEL GOVERNOR TO RESOLVE BINDING AND CLUTCH CONCERNS. A PGG GOVERNOR WAS INSTALLED ON AFPT #2 DURING LAST REFUELING OUTAGE.
IMPROVED MAINTENANCE AND TESTING ON LIMITOROUE VALVE OPERATORS.
MOTIVE STEAM TO BE SUPPLIED DIRECTLY TO THE STEAM ADMISSION VALVES
~
ALIGNING ALL M0V'S IN THE N0RMAL PUMP DISCHARGE LINES NORMALLY OPEN. ,
INSTALLING ONE AIR OPERATED-FAIL OPEN VALVE IN THE STEAM SUPPLY LINE NEAR EACH AFPT TO RESOLVE CONDENSATION CONCERN
PLANNED MODIFICATIONS TO RESOLVE HISTORICAL CONCERNS '
(CONT'D)
. INCREASE MESH SIZE OF THE CST DISCHARGE STRAINER TO AFP TO REDUCE PRESSURE DROP IN SUCTION LINE.
. ELIMINATE BASKETS FROM THE AFP SUCTION STRAINERS.
. REVISE SUCTION TRANSFER LOGIC TO MINIMIZE SPURIOUS TRANSFER TO SERVICE WATER INSTALL NEW 800 GPM MOTOR DRIVEN FEED PUMP I
D
. . l INSTALLATION OF MOTOR DRIVEN FEED PUMP
. INSTALL NEW MOTOR DRIVEN FEED PUMP PRIOR TO STARTUP
, UEW PUMP DESIGN FEATURES:
. PROVIDES 100% CAPACITY AUXILIARY FEEDWATER FLOW
. PUMP DISCHARGE ALIGNED TO THE AUXILIARY FEEDWATER HEADERS DURING NORMAL FULL POWER OPERATION
. PUMP SUCTION NORMALLY FROM THE CONDENSATE STORAGE TANK
. PUMP CAPABLE OF BEING ST,ARTED FROM THE CONTROL ROOM e
l
l INSTALLATION OF MOTOR DRIVEN FEED PUMP PRE-STARTUP (CONT'D)
. PUMP MOTOR CAN BE SUPPLIED FROM EITHER EMERGENCY DIESEL GENERATOR FOLLOWING A LOSS OF 0FFSITE POWER CAN BE MANUALLY REALIGNED TO FEED THE MAIN FEEDWATER SYSTEM. THIS WILL BE THE NORMAL ALIGNMENT DURING LOW POWER OPERATION. PUMP SUCTION IN THIS ALIGNMENT WILL BE FROM THE DEAERATOR STORAGE TANK.
