~

Wind Speed and Direction The wind speeds and directions from the old and ne towers agree very well over the three month period cal wind roses from the 33ft and 150ft levels on the old towerFigu through 5 are wind roses from the new tower at the 33ft Figures 3 levels, respectively.

,148ft and 195ft The main difference in the wind roses is t percentage of calm wind speeds.

instrumentation had no hours of calm wind speed.The The old tower had 2.4%

and 0.4% calm wind speeds at the 33ft and 150ft levels The only minor difference in the wind direction is that there greater percentage of west-northwest winds on the old tower was a west-southwest winds on the new tower.

Table 2 shows a comparison of monthly average wind speeds from the old and new towers.

The wind speeds are quite consistent and agree well.

Vogtle Old and New Meteorological Towers Temperatures Both the ambient and dew point temperatures agree quite well.

Table 3 shows monthly average temperature and dew point temperature data from the old and new towers.

There are some minor differences particularly in the dew point temperatures. These differences can be attributed to the fact that the dew point units are difficult to calibrate and any two units are likely to give somewhat different readings.

The joint frequency tables of wind speed and direction versus delta temperature are shown in Tables 4 through 7 and summarized in Table 8.

The tables show some discrepancies between the old and new meteorological towers. When grouped by the general categories of unstable, neutral and stable conditions, the two towers compare quite well. The cifferences between the two towers can be attributed to different instrumentation and, therefore, calibration.

The delta temperatures on the old tower were adjusted in April.

It is possible that with a larger data base the differences between the two towers could be reduced.

Discussion of Water Losses Near the Top and Base'of Marl in' Hole 107 LDuring the'Feb.L12, 1985 NRC-Applicant meet'ing on ground water conditions

.at Plant Vogtle,Lthe staff requested the applicant to discuss the cause of

~

water' loss at the4 top and bottom of the. marl shown on the log for hole.107.

C 2The'following is a short discussion on the water losses, based solel'y on the drill logs.

The drill log for 107 indicates that the. top of the marl is at a-depth of

74 ft and.that-NX casing was set to 75 ft.

The next drive sample was taken from-78.5 to 80.0 ft.

The log' reports a water loss at a depth of 79.5 ft or while sampling was underway. The jarring action of' drive sampling

-in the casing probably caused 'a-loss of the seal between the casing and the-marl. The. casing.was.then advanced to 87.0 ft.

No additional fluid loss occurred until near the base of the marl, which is expected. Setting the. casing.only one foot into the marl was not normal practice, the casing more'was; commonly set 5 ft;into the marl.

A fluid loss at the' base of.the marl occurred at'a depth of 140 ft.

The contact between the marl and underlying silty sand is shown to be at 143 ft.. The base of.the marl is. frequently altered.or becomes gradationally more sandy.at its contact with-the silty sand. The lower sands are more permeable and typically result in fluid loss. The contact between geologic units was determined primarily with the split spoon samples taken every 5 ft.

~The contacti could. occur between 140 and 143.5 ft.

The log for drill hole 107A located.15.f t to the east-northeast of 107 shows the base of the marl Lat'137.5.ft.

Therefore, the loss of fluid at 107 could have occurred at

~

the contact between the marl and the underlying sands.

.The' marl between these fluid loss areas at the top and bottom did not show any evidence of fluid loss or zones of soft material. This 60 ft consistently impervious material which provides a competent. bearing strata as well as-

.an1 effective aquiclude between aquifers.

Drill, hole 107A did not' indicate any fluid loss in the same zones as 107

~nor did it show any soft, fractured or void zones near the top or base of l

'the marl. 'Therefore, it is believed that the fluid losses in 107 do not L

represent.a more permeable zone or void area within the marl.

a 6.6.3 EXAMINATION TECHNIQUES AND PROCEDURES The
visual, surface,~and volumetric examination techniques and

. procedures.are-in accordance with the requirements of American

-[

Society of Mechanical Engineers Code,Section XI, subarticle IWA-2200 4-The liquid penetrant or magnetic particle methods are used for surface examinations. ' Radiography or ultrasonic methods,

,whether manual or remote, are used for volumetric examina'tions.

I The reportable indications and data compilation format provide for comparison of data from subsequent examinations.

GPC will apply the code cases listed in Regulatory Guide 1.147 on a case-by-case basis as the need arises during the preservice inspection.

No code cases will be used for the preservice or inservice inspection other than.those approved for us in Regulatory Guide 1.147.- When used for Section III, Class I construction these code cases will be identified in the FSAR.

RESPONSE TO IE BULLETIN 79-15 (SRP 3.10.2)

DSER OPEN ITEM 26K In response to IE Bulletin No. 79-15, the only deep draft pumps similar to those identified in the bulletin are the six (per unit) nuclear service cooling water (NSCW) pumps and two (per unit) -NSCW transfer pumps. The functions of these pumps are described in subsections 9.2.1 and 9.2.5.

The salient data for these pumps are as follows:

.o < Nuclear Service Cooling Water Pumps Manufacturer: Bingham-Willamette Company

.Model:

18x27B VCM,:2 stage self-lubricated Rated Capacity: 8600 gpm at 230 feet TDH Overall Length:

94' - 3 3/4" Width (with motor):

3' - 5" o Nuclear Service Cooling Water Transfer Pumps Manufacturer: Bingham-Willamatte Company Model: 8x12A VCM, 2 stage self-lubracated Rated Capacity: 600 gpm at 110 feet TDH Overall Length:

94' - 7/8"'

Width' (with motor):

2' - 4" As part of the program to ensure long-term operability of these pumps, the pump shafts are provided with reversable precipitation hardened stainless steel sleeves. The. sleeves are positioned against a shoulder, with keys used.to prevent rotation on the shaft.

Pump degradation due to debris, contamination, or' impurities in the process fluid is minimized by trash screens and. mud sills at the pump inlets, and by continuous control of the NSCW tower basin' chemistry. Also, as part of the inservice inspection program, pump performance (flow and head) will be periodically monitored in accordance with Section XI of the ASME code to detect pump performance degradation.

In addition, vibration sensors are mounted at each end of the pump shaf ts to detect bearing /shaf t sleeve problems.

Because the pumps are not yet installed and operational, there is as yet no list of pump startup, preoperationdi testing, operating experience, or maintenance.

Such information will be accumualated as it becomes available, and will be made available for inspection at the plant site. Also to be made available for inspection at the plant site will be:

o-Pump drawings, sectional assemblies, design specification (X4AF02),

and parts list o Quality assurance records The Equipment Qualification Data Package (EQDP), including results of o

the qualification program.

o Details of the procedure used to align the pump column m

l Because the VEGP SSMP does not automatically illuminate all of the interfaces i

between the various systems monitored, an initial assessment and response matrix is being developed (a preliminary copy of this matrix is attached).

l This matrix will be used by the Operator to determine which "-

r77^"

'" " systems are potentially inor.erable due to an initial automatic indication of an inoperable or bypass condition occuring for a specific moni-tored system.

Also, the matrix allows the Operator to illuminate all affected systems doe to an initial man /ual illumination of a SSMP window.

The Operator will manually illuminate the windows of systems identified by the matrix as l

being potentially inoperable by selecting the " Bypass" position on the window switch.

This matrix will be readily available to the Operator since it will be included in the Plant Data Book and will be referenced in Operations Admini-strative Procedure 10005-C " Operability Status Indication for Plant Safety Systems".

Subsequent to this initial rapid illumination of affected system windows, l'

the Operator will use an Annunciator Response Procedure (ARP 17004) as the diagnostic tool for detecting exactly what caused the initial automatic annunci-ation.

Upon discovery of the initial failure / problem, ARP 17004 will direct the Operator to begin corrective action and also to update the SSMP to extin-guish those system windows proven to be unaffected.

This will leave only those windows illuminated which have systems / components truly inoperable, b

s

' Additional Information For Open Item 64 - Continuation Sheet Page 2 of 2 This methodology, as described above, will be used for all SSMP window illumina-tions-except those which occur from a pre-planned evolution.

For pre-planned evolutions only the initial illumination of-the SSMP utilizing the matrix will-be ' performed.

The SSMP.will then be restored at the conclusion of the evolution.

The reactor makeup water J

system is also designed to provide a backup source of makeup water for the spent fuel pool, component cooling water system, auxiliary component cooling water system, and the ESF chilled water systems.y The water is delivered through manual operation of the reactor makeup pumps in conjunction with the seismically designed portion of the piping and' valving.

The pumps are

. manually loaded onto the non-1E emergency bus after all safety loads have been automatically sequenced.

In addition, makeup water can be provided to the spent fuel pool via the Seismic Category 1 header, using gravity as the driving head instead of the pumps.

The p rtion of the eactor makeup water syst'em require o

as a. backup source of makeup water for the spent fuel kkler system.

serv pool is designed and built to Seismic Category 1 requirements.

/he iping between the safety-related reactor makeup water tank h

anda ther safety-related systems is Seismic Category 1.

Two Q

9eismic Category 1 air-operated isolation valves are provided 40 to. effectively separate the seismic piping from the nonseismic j

. portion of the system.

These valves receive train-related electrical power and are controllable from the main control room.

In addition, the Seismic Category 1 header is automatically l isolated from the Seismic Category 2 header on a low-level signal from the reactor makeup water tank.

. Since makeup water is not required immediately following a design basis event, the reactor makeup water pumps are not considered safety _relatad.

However, they are seismically designed and follow the material requirements of American Society of Mechanical Engineers III, Class 3.

This ensures the integrity of the flow path and provides reasonable assurance of the operability of the pumps. ' Power for the pumps is supplied from train-related, non-1E electrical buses.

In an emergency, I

these non-1E buses can be manually loaded onto the 1E'onsite

. power source-once the automatically started, safety-related loads are running.

Should both motors fail, the Seismic

< Category-1 piping and pump casings provide a flow path to allow gravity-induced flow from the storage tank to the spent fuel pool.

9.2.7.4 Tests and Inspections No special tests or features for unique inspection capability are provided since the system is normally in continuous i

operation and individual components are readily accessible.

.[

As described in detail in section 6.3, the refueling water storage tank (RWST) provides a source of water for the emergency core cooling operations.

The RWST is a nuclear safety class, seismic Category 1 structure..However, the aludge mixing pump and the electric circulation heater connected to the tank do not meet these qualification requirements;.therefore, an isolation capability is provided to prevent a loss of the RWST water volume.

Two train-oriented,

- air-operated, seismically-qualified valves mounted in series on the suction line to the sludge mixing pump provide this capability.

When closed, they isolate the safety-related

. portion of the line (connecting to the RWST) from its nonsafety-related, nonseismic portion connected to the sludge mixing pump.

Both valves fail closed upon the loss of

-(*

instrument air and/or control power.

Each valve is automatically actuated to close upon a RWST low-level signal from a redundant level switch in its respective safety train.

'The isolation ve,1ves will remain closed until individually opened by the operator's manual action.

Such action will result in the opening of the valve only if the RWST low-level C

signal is no longer present.

1 The capability for remote-manual isolation from the control room is p.lso provided.

The status of each isolation valve is displayed by the indicating lights in the control room.

The oxygen concentration is measured by process ana.yzers in which an electric current is generated at an electrode in proportion to oxygen dissolved in a flowing sample stream.

Oxygen is also measured on a grab sample by color comparison after reaction with a reagent.

B.

In the absence of significant impurities, the pH is centrolled by the concentration of ammonia and hydrazine.

Maintaining the pH within the recommended band results in minimal corrosion rates of ferrous materials.

The pH is measured in both process and bench instruments which measure the potential across an electroce sensitive to hydrogen ions and a reference

~

electrode.

C.

By passing the sample through a cation resin column, conductive anions (such as chloride, sulfate, and to a lesser extent carbonate) can be indicated in a conductivity cell.

Cation conductivity is a sensitive method for indicating soluble species which have been indicated in many localized corrosion mechanisms.

D.

Sodium is an effective continuous indicator of many forms of containment ingress.

The ability to analyze for the species at the low ppb level makes it a very 15-useful chemical tracer.

Increased sodium levels can be indicative of condenser leakage or makeup water contamination.

Sodium is measured by process analyzers using specific ion electrodes.

Grab samples are analyzed by furnace atomic absorption.

E.

Silica is an effective continuous indicator of many forms of contaminant igress.

The ability to analyze for this species at the low ppb level makes it a very useful chemical tracer.

Increased silica levels can be indicative of a condenser leakage or makeup water contamination.

Grab samples are analyzed for silica by spectrophotometry.

E.

Chloride is aggressive to ferrous materials at steam generator operating conditions, particularly in crevice regions.

It also has been identified as an aggravant relevant to inconel 600 pitting.

Grab samples are analyzed for chloride by ion electrode.

The chemical analysis methods listed above represent current tachnology applicable for power plant laboratories.

These methods may be changed over the lifetime of the plant as new technology is proven to be more effective.

10.3.5.8 Sampling In addition to the sampling locations listed in table 10.3.5-1, many other sampling points are installed in the secondary side water system.

These sampling points are identified in table 9.3.2-3 (grab sample points and process instrumentation) and table 9.3.2-4 (grab sample points).

These sample points include hotwells, condensate storage tank, condensate, feedwater system, auxiliary feedwater system, steam generator blowdown, reheat steam, and heater drains.

Many of these points will be sampled and analyzed routinely, others only as needed for troubleshooting and problem diagnosis.

No action levels are associated with these sample points, because contamination which leads to corrosion is best identified and controlled at those points identified in table 10.3.5-1.

15 10.3,9 Condenser Inspection

.The secondary side water chemistry program will include a comprehensive inspection program of the condenser will be developed to ensure condenser integrity.

This program includes a visual inspection of the condenser every refueling outage, waterbox inspection for tube leaks during plant operation, and component inspection for oxygen leaks during plant operation.

These water box inspections and component inspections will be performed as necessary to diagnose and troubleshoot abnormal chemistry levels.

10.3.5.10 Analytical Data Recording and Management and Corrective Actions for Out-of-Specification Condition i

All analytical data will be recorded on pre-drawn data sheets, es the data are taken in the laboratory.

The data sheets will contain the specification values for parameters being analyzed, or will contain the expected ranges for analyses performed to aid diagnostics.

The technician performing the analysis will compare the analyzed value to the specifications value, where specifications are established, and promptly report any valuns 10.3.5-7 Amend. 15 3/85

The installation of the filter assembly follows a specific procedure that minimizes the potential for the HEPAs and adsorber to be damaged.

The DOP and tracer tests cannot be accomplished on an individual or overall basis at this time.

Section C.5 also requires in-place HEPA DOP and adsorber leak testing at intervals of every 18 months.

The expected change-out frequency of the filters is every 6 months at which time the on-line filter is valved out of service and allowed to decay.

At that time the idle filter is valved into service and used.

If it is assumed that the turbine building flood detectors and the circulating water basin level detectors fail, the flooding could continue until the basin is empty. As the water level rises in one unit, the concrete block wall between units will fail due to high static water pressure, allowing the water to spread into both halves of the building. Calculations have shown that the block wall will not withstand more than 8 feet of water and will fall before the water level reaches the operating deck at elevation 220' 0".

, Question 430.2 N Operating experience of two nuclear power plants has shown that

"}

during periodic surveillance testing of a standby diesel generator, initiation of an emergency start signal (loss-of-coolant accident or loss of offsite power) resulted in the diesel failing to start and perform its function due to depletion of the starting air supply from repeated activation of the starting relay.

This event occurred as the result of

  • )

inadequate procedures and from a hangup in engine starting and control circuit logic failing to address a built-in time delay my relay to assure the engine comes to a complete stop before attempting a restart.

During the period that the relay was timing out, fuel to the engine was blocked, while the starting air was uninhibited.

This condition, with repeated start attempts, depleted starting air and rendered the diesel generator unavailable until the air system could be repressurized.

Review procedures and control system logic to assure this event will not occur at your plant.

Provide a detailed discussion of how your system design, supplemented by procedures, precludes the occurrence of this event.

If during the 90-s time delay period a loss-of-offsite power signal is received or a manual start attempt is initiated, the engine will not start because fuel to the engine will be blocked.

If the operator depresses the manual start pushbutton during the 90-s time delay period, the starting air valves will open for 5 s and automatically r~)

air pressizra drops to 150 psig.

At this pressure, the automatic start attempt will stop because at 150 psig the starting air valves automatically close.

At this point, the engine can only be started manually by pushing the manual start button.

Pushing the manual start button will cause the starting air valves to C

open again.

There is no built-in time delay between the V

conclusion of the automatic start sequence and the manual start attempt.in a situation as described above.

In other words, if the engine fails to start automatically, a manual start can be initiated immediately.

The starting air sequence is designed in this manner so that the manual, start attempt capability is A

available if an automatic. start attempt fails.

The engine can be manually started in this manner until the starting air pressure drops to 90 psig.

Generally, starting air pressure below 90 psig will not start the engine when an attempt is initiated.

@ Loss of offsite power to the plant is discussed in subsection 15.2.6.

If I

.~one diesel generator is being tested and then is manually stopped at the time of loss of offsite power, the other diesel generator would automatically start without any delay to provide the emergency power. If in addition, it is assumed that the diesel generator that is not being tested fails, there would be a 90 second delay before the other diesel generator automatically startsi.

However, the auxiliary feedwater turbine driven pump system which starts automatically on a loss of offsite power signal relies only on emergency DC power. The 90 second delay in the diesel generator start would not prevent auxiliary feedwater from being delivered to the steam generators and thus the analysis presented in subsection 15.6.2 envelopes the VEGP design.

g.,

The storage tank went b6me is branched into two separate 4-in vent lines 4

i downstream of the flame arrestor located inside of the valve house. One branch is externally terminated in an open vent above the valve house roof and the other branch, oriented 900from the first vent, is esterna11y terminated in an open vent outside the valve house wall.

7 Thus, all storage tank vents terminate outside of the valve house / which l

precludes an accumulation of combustible gases within the structure.

I Furthermore, diesel fuel oil is a heavy distillate which, by virtue of l

its specification, does not contain light petroleum distillate products such as propane, butane, or gasoline which are volatile and readily form combustible gases. Therefore, at room temperature the means for producing appreciable amounts of combustible gases are not present.

The second storage tank vent, flame arrestor, and connected piping are missile protected.

In the unlikely event that both of the diesel fuel oil storage tank went lines outside of the valve house are damaged or blocked, the storage tank can be vented through the second vent when the fuel oil transfer pump is in operation. The fuel oil transfer pump creates sufficient differential pressure between the vaper pressure within the tank and the ambient atmosphere to ensure proper transfer of diesel fuel from the storage tank to the day tank, regardless of the L condition of the storage tank vents.

If necessary, emergency venting of the storage tank can be accomlished by unbolting the side plates of the flame arrestor or by opening the storage tank man way cover.

VEGP-FSAR-Q Question 430.33 In FSAR paragraph 9.5.7.5 you briefly discuss the low -lube oil Expand your FSAR-to provide additional pressure trip.

information on this trip function, including more details on the the location of pressure switches (manufacturer, model, etc.),

these switches on the diesel generator, and identification of these switches on the piping and instrumentation diagram (figure 9.5.4-1).

. r

Response

The low pressure lube oil trip function is provided for the automatic safe shutdown of the engine during both normal and emergency operations.

It is a two out of three logic (see paragraph 9.5.7.2.2).

This means that there are three oil sensors installed on the engine luhe oil inlet header.

The lube oil pressure sensors are set to trip open at 30 psig decaying Their operation is similar to mechanical valves which pressure.

are closed when pressure is above 30 psig and trip open on l

These sensors are monitored by a series of decreasing pressure.

pneumatic logic circuits mounted inside the engine control In the event that any two of the sensors are tripped panel. they vent 60 psi pressure from an alarm / shutdown circuit

open, in the pneumatic safety system.

When venting occurs, a control air pressure extends the fuel rack shutdown cylinder at the engine.

The cylinder moves the fuel racks to the no fuel position, and the engine stops due to fuel starvation.

At the same time, a pressure switch in the engine control panel indicates to the electrical. system that a. malfunction has occurred in the lube oil system.

1 The oil pressure sensors are manufactured by California Controls Company (model B-4400), and the pressure switch is manufactured Inc.

by Barksdale Controls Division,.Transamerica Delaval,

-(model E15-M90).

The oil pressure sensors and switches are furnished by the engine manufacturer as integral parts of the engine and control panel. *They are shown on engine pneumatic schematic and engine control panel schematic drawings furnished by the vendor.

Therefore, they are not shown on the piping and instrumentation

(

13 diagram.

The high temperature jacket water and low pressure lubricating i

oil sensors remain active for tripping during the emergency i

operation.

As shown on. figure 430.33-1, three sensors are used

!f to monitor each of these parsmeters.

At least two of these sensors must trip $before a shutdown occurs.

For example, if l \\

Amend. 7 5/84 Q430.33-1 Amend. 13 1/85

VEGP-FSAR-Q only the low pressure lubricating oil sensor on line 10A trips, there is a loss-of pressure at port 1 of the UPPER lA.6943 assembly.

This causes element.MEM-5 to stop transmitting which, The NOT-9 i

in turn, causes element NOT-9 to have an output.

and is also output is applied to port "A" of element AND-13, applied to port 8 of the assembly through elements OR-17 and i

OR-18.

Pressure at port 8 activates pressure switch PS-48N which indicate to the electrical system that one of the luce oil sensors has malfunctioned.

If a second lube oil sensor were to indicate a malfunction condition, the engine would shut down.

i For example, if the sensor on line E-LOB vents, in addition to g

the sensor on line E-LOA, then the loss of pressure at port 3 of f

the upper lA-6943 board would result in an output from element l

AND-13.

The AND-13 output pressurizes port 6 of the assembly, and is also applied to both port "B" of element NOT-12, and to an accumulator pair at port 11 through orifice / check 16.

Port 6 pressure causes pressure switch PS-42N to transmit the trip l

indication to the alarm system.

NOT-12 has an output for approximately two minutes, until terminated by the accumulator j

timer.

The NOT-12 output pressurizes port 12 of the upper assembly, and is transmitted through the lower assembly to pressurize port 4 of logic board 1A-7055.

Note that the port 4 stop signal bypasses the NOT-17 and NOT-18 elements which 13 ~

I inhibit a normal safety shutdown.

The port 4 signal produces a memorized output from element AND-24 which ext. ends the fuel rack

'Once the diesel-generator is running at a' sustained load, the' engine g,g3,el G..

will keep on running even'though the pneumatic control air system is 3/26l&fSqh-disrupted and becomes unavailable subsequent to engine start.

The continued operation of the diesel-generator is possible without pneumatic control system due to the following reasons:

o The fuel pump is engine-driven and does not require pneumatic control.

o The engine governor is electrically operated and is provided with an integral independent mechanical. backup neither of which require the

. pneumatic control air system to sustain operation.

o The fuel shutdown cyclinder is normally open and air supply is required to move the cylinder to a 'no fuel" position. Therefore failure of the air supply to the pneumatic logic control will not cause the diesel engine to stop due to fuel starvation.

o The safety-related sensing lines for the 2 out of 3 trip logic for' low pressure lube oil and high temperature jacket water can be vented only by sensor actuation. These sensing lines are pressurized during startup via safety-related check valves 1, 2

  • and 3 (see Figure 430.33-1, sheet 1).

The check valves will maintain these lines pressurized in case of an air supply failure.

If a 2 out of 3 trip signal is generated after an air supply failure, the pneumatic logic will not be operable to provide an, output signal to the shutdown cyclinder.

In addition, no air will be available to move the shutdown cylinder to "no fuel" position.

'Therefore, the failure of air supply system will not cause fuel starvation to the diesel.

Starting air quality is discussed in subsection 9.5.6.

The pneumatic control system air quality is the same as for air start system.

" manufacturer's standard."

In addition, the diesel engine exhaust silencer, exhaust piping, and flexible connections are l

listed as being designed to " manufacturer's standard" or an ASTM standard.

This is not acceptable without further justification.

The staff normally requires the entire diesel engine combustion air intake and exhaust system to be designed, fabricated, and

. installed in accordance with ASME Section III, Class 3 requirements.

Provide justification for noncompliance.

Response

The combustion air intake piping As designed to Seismic Category 1, ASME Section III, Class 3 requirements, and the project class designation is 013.

However, due to the high operating temperature of the engine exhaust, there are no acceptable materials available that will meet both ASME Section III, Class 3 requirements and the operating temperature requirements.

Therefore, the exhaust piping is designed in

(...

accordance with ANSI B31.1 with stress allowables in accordance with ASME Section III.

The material used is ASME II SA-155, KC 70, Class 1 carbon steel, rolled and welded pipe.

The pipe is manufactured from SA-515 Grade 70 plate.

Material allowable stresses are based on SA-515, Grade 70 at 900 "F and are found in ASME Code Section 1, Table PG-23.1, 1974 Edition with Addenda through Summer 1975.

Insert A: The monitor light box for valve BV-8803A is MLB05, which is powered from distribution panel 1AYC1 (NCC 1ABC). Valve BV-8803A is powered from NCC.1ABD. The monitor light box for valve 5V-88035 is NLB06, which is powered from distribution panel 18YA1 (NCC 1BBA). Valve BV-88038 is powered from NCC IBBD. ~ Insert B: ? In the event that the switch contacts on either the hot leg or the neutral leg i of the circuitry fail to open (undetected failure) the control circuit will still be disabled and the white light will still be deenergized, because the switch contact on one of the circuit legs (either the hot leg or the neutral 3 leg) is open, rendering the control circuit loop open. Assuming that, in [ addition to this failure, a second failure occurs such that the switch contact that' opened when the lockout switch was initially placed in the " lockout" position shorted out or became bypassed, two things can happen. The second _ failure can generate a short circuit which will open the fuse (installed to 4 J l protect the circuit from this incident). The opening of the fuse will, isolate the fault and at the same time will doenergise and disable the control j circuitry. On the other hand, the second failure can complete the control l circuit loop such that the control circuitry is energized and the white light l ' turned on. This condition will indicate to the operator a discrepancy and j that a problem exists in the power lockout control circuitry and that some measure has to be taken to correct the situation. Suppose that instead of the i I ~ white light being energized a third failure occurs, which causes the bulb filament of the white light to fail. In this case, the doenergized white light (defective bulb) would indicate that the lockout circuitry is disabled, l although, under this particular condition because of the different failures postulated above, the lockout circuitry is in fact energized. Still, a fourth failure will be required to take place - that of an operator action, accidental or otherwise - to change the position of the valve. If the operator actuates the switch which will change the position of the valve, visual and audible indications from three different places will be actuated. The system status monitor panel will provide visual and audible indication on a system level that a particular condition has been violated. Concurrent with this, the annunciator panel will provide visual and audible indication, on a group level, and identify the group to which the affected component belongs. The monitor light panel, which arranges the components in groups, will provide visual indication on a component level and identify exactly the component, the position of which was violated. As postulated above, it will require four successive failures (beyond the single failure criterion) to bring the lockout control circuitry to a condition that will allow the valve position to be changed. Assuming, however, that such a condition can be obtained, the presence of redundant visual and audible indications alerting the operator of the violated condition will prevent the condition from taking place. On the other hand, let's assume 0080m l

-that the undetected failure-occurred in the switch contact in the neutral leg of the power lockout circuitry and that a hot short occurred in the hot leg of the circuitry such that the valve solenoid is energized and the valve position is violated. As discussed above, this condition will cause variance levels of visual and audio indications to actuate which will-alert the operator of the violated condition and will therefore prevent the valve position from being reversed. Moreover, the occurrence of accidental hot shorts which will cause-the valve's solenoid to be energized and change position is not credible. The wires are terminated on terminal blocks with barriers between the block points so as to prevent adjacent points from shorting each other. In addition, the points in question are terminat.ed far apart such that the only credible hot short is ~ obtained by intentionally connecting the points manually with a long piece of bare copper wire. Insert C .The position indicating lights.on the handswitch for each. accumulator isolation valve indicate the open or closed status of the valve when it is stroked open for operation at power or stroked closed for shutdown. When the isolation valves are padlocked in the open position during reactor power operation by locking open the circuit breakers, these pocition indicating lights on the han'dswitch will be deenergized. At this time, this position is monitored by MCB annunciators or in the monitor light box. The position signal is from'a contact on the valve cam operator switch. Another contact on the valve. cam' operator switch signals the critical function valve alarm that the valve is.not opened. There is also a critical valve reflashing alarm that indicates when the valve is not fully open which is signaled from a stem mounted limit,s. witch. These diverse indications warn the operator if the valve is not open when it is required to be open for correct ECCS alignment. The power supplies to the MCB annunciators'on the monitor light box are independent of the power provided to the valves. ;"! 0000A i 9 "ili h'ee y --. Icet;d cut.

+111 b: rer.e"eA ar Valves 8803 A and B are the Boron Injection Tank (BIT). inlet isolation valves. In'the past, the BIT was filled with concentrated boric acid (20000 ppm boron), and the system was' required to be isolated from the normal charging and ECCS injection paths by the BIT solution and also preventing inadverten't boration of the RCS. Recently, analyses have shown that the high boric acid concentration is not needed for a safe shutdown after a LOCA, and the decision was made to lower the concentration in the BIT solution to 2000 ppm boric acid, which is the normal concentration of the ECCS water. As a result of this change, the requirement' for having the BIT inlet and outlet isolated was eliminated. To minimize changes to Plant Vogtle while still maintaining an increased operability factor for the BIT system, the inlet isolation valves HV-8803A and B will bc locked in the open position, and electrical power will not be connected to the valves motors.

VEGP-FSAR-lO )r The power-operated atmospheric relief valves also serve'to l14 L prevent operation'of the safety valves during.relatively, mild transients and,-following safety valve actuation, act to assist the safety valves to positively reseat by automatically reducing ~ -.and regulating steam pressure to a value below the safety valve g resenting pressure. The operation of each power-operated atmospheric relief valve is controlled from a pressure tap on the steam generator steam line with which it is associated. This piping connection is separate from the.other steam piping -pressure taps which are used for reactor protection, to satisfy the requirenent for separation between control and protection systems. The power-operated atmospheric relief valve consists of-a l14 Control Components, Inc., pressurized seat offset globe drag valve'(8-in. inlet-offset, 10-in.. outlet, 900-lb valve rating) with electrohydraulic actuator and a restrictor. The nuclear 1 Class 2 globe drag valve is located inside the MSIV areas; the restrictor (silencer) is placed on a roof outside the control and auxiliary buildings to vent to atmosphere. The noise 1 attenuation is divided into two stages: one by the disk stack inside the main globe valve and the second by the disk stack in I the restrictor. This design approach reduces the size of the main valve and the size of the restrictor. The combined design has the capability of controlling the distant field noise as ) ~ well as the local field noise. It is sized for a sound pressure level of 90 dBa at 3 ft near field noise and less than 55 dBa at 4000 ft for far field noise. The atmospheric relief valves are electrohydraulically operated l and are controlled by Class 1E sources.

3 Insert to 10.3.2.2.3 The valve operator is a self-contained linear modulating electro-hydraulic valve operator for use with~an 8 I 10 inch globe drag valve. On loss of power and/or signal, the actuator will extend the operator and close the valve. The operator is mounted on the valve by attaching the base plate to the gland of the i valve. The operator rod is attached to the line valve stem. The primary function of the operator is modulation. The actuator recognizes.4 to 20 milliamp command signals: four milliamps represents full extension (valve closed) and with increasing signal the actuator retracts (valve opens). The incoming signal is compared to the feedback signal coming from the position transducer by an on-board servo amplifier. If there is a change I from the previous level greater than the deadband..the actuator is i set in motion until the corresponding position is reached. Loss l of command signal will extend the operator and close the valve. I The system stores energy in a pneumatic accumulator and gas bottle pressurized by an electrically driven pump which is controlled by two fluid pressure switches; one to turn pump actor on (decreasing) and the other to turn pump motor off (increasing). Opening or closing during normal operation is accomplished by either energizing both solenoids or de-energizing both solenoids, to either retract (open valve) or extend (close valve) the operator cylinder rod. Manual overide of the solenoid is necessary for operating the valve operator during a 115 VDC power loss. Speed or retracting (opening valve) or extending (closing valve) is controlled by a flow control valve which meters the flow of hydraulic fluid from the cylinder to return. The operator can be positioned by means of a hand pump in the event of pump failure with the solenoids in the proper mode. The electrical system consists of servo-valve, three pressure switches (one for gas, two for oil) and a reservoir low fluid level indicator. The system also features a servo amplifier which compares incoming command signals with actuator position feedback transducer and then energizes the corresponding solenoid valve to comply with the command. The hydraulic system stores sufficient energy to perform its intended functions. The energy is stored in an on-board piston i type accumulator. Charging is initiated by a " fluid" pressure switch which is set to indicate the minimum system pressure necessary for proper operation. When the minimum is reached the system's hydraulic power supply is turned on to restore the system to its peak pressure. Upon reaching maximum, systes pressure as indicated.by another pressure switch, the power supply is turned off. As the operator modulates, the system pressure drops. When the minimum. pressure switch set point is reached, the above process repeats and the actuator is recharged. l 2154t 4

= __ _ l l For modulation, the dual coil servo valves in the system are operated. This is automatically done by the servo amplifier when there is a change in the incoming signal. To extend the actuator (and close the valve) solenoids AGB are de-energized. Upon reaching the set point when extending, solenoid B is energized to stop the actuator. If a command signal is received to retract the actuator, the servo amplifier energizes solenoids A&B. At the set point, solenoid A is de-energized and solenoid B remains energized (as extending). The hydraulic circuit is protected from extreme pressure transients by two thermal relief valves. These valves become active when their relief setting is exceeded. Reseat is automatic. Stroking speed is controlled by a cartridge type flow control valve which is preadjusted to provide the specified stroking speed. l i r i e M i 2154t 5 i
