C) ACCURACY DISCUSSION-ANALYSES X The accident accuracy of this instrument for normal, post seismic and conditions will be determined by considering the parameters tabulated in the design input calculation. section of. this The accuracy calculation for seismic (As) is bounding for all seismic events.
_.X_ The square root of the sum of the squares method shall be used in this calculation for calculating accuracy since the - factors -
affecting accuracy are independent variables.
_.X_ Bi-directional errors and uni-directional errors combined in a will be manner such. that the sum of the positive uni-directional errors will be added to the positive portion of the bi-directional error (obtained from the square root of the sum of the squares method), and the sum of the negative uni-directional errors will be added to the negative portion of the bi-directional error.
This method is conservative. Therefore,-it will be used in this 1
calculation.
Example:
(+/-)10 = bi-directional error
+5 = first uni-directional error
-2 = second uni-directional error Total Error = (+10 + 5) to ( 2) = +15 to -12 s other:
k For the purpose of this calculation, accuracy is defined'as the range of actualtrip bistable process value,values that may exist for a given indicated or e.g. an accuracy of +1 that for an indicated or bistable trip value,0 ofps'ig to--5 100 psig, psig the means actual process pressure may be anywhere between 95 and 110 psig.
All system analysis based on or using accuracy values from this .
calculation should take into account the fact that operator action -
and/or automatic initiations may occur at a process value differing form the indicated or setpoint values by the amount of the calculated inaccuracies.

- TO DEVIATE O,.9-5-85, ALLOWS CALIBRATION TECHNICIANS.
FROM THE APPLICABLE SI OR IMI WHEN -CALIBRATING THE~
TRANSMITTER IN THAT LOOP. THE DEVIATION ALLOWED IS THAT IF THE APPLICABLE SI, OR IMI INSTRUCTS THE TECHNICIAN TO USE THE TEST POINT RESISTOR TO CALIBRATE THE TRANSMITTER, THE TECHNICIAN MAY ALTERNATELY CHOOSE TO CALIBRATE THE TRANSMITTER BY LIFTING A. LEAD ON THE TRANSMITTER AND PLACING AN AMMETER IN SERIES ' WITH THE TRANSMITTER TO MEASURE ACTUAL OUTPUT CURRENT.
BECAUSE OF TI-93, THE EXACT MANNER IN WHICH ANY GIVEN TRANSMITTER WILL BE CALIBRATED CANNOT BE DETERMINED. A REVIEW OF PREVIOUS CALCULATIONS SHOWS THAT WHEN THE TWO METHODS ARE COMPARED, THERE IS ' ONLY ANg APPROXIMATE 10.01% DIFFERENCE IN CALIBRATION METHODS. MAGNITUDE BETWEEN THE TWO LOOP FINAL RESULTS ARE CONCERNED.
THIS DIFFERENCE IS NEGLIGIBLE AS FAR AS THE THEREFORE, FOR THE PURPOSE OF THIS CALCULATION, USE A- DIGITAL MULTIMETER (DMM) IN SERIES WITH TRANSMITTER TO READ CURRENT VALUE.

A) AN "SI" SIGNAL IS PRESENT AND B) THE RWST LEVEL IS BELOW THE I4W LEVEL SETPOINT ON TWO OF THE FOUR RWST LEVEL CHANNELS AND C) THE CONTAINMENT S ' UMP LEVEL IS ABOVE THE HIGH LEVEL PERMISSIVE SETPOINT ON TWO OF THE FOUR CONTAINMENT SUMP LEVEL CHANNELS.
IF THE ABOVE CONDITIONS EXIST, THE RHR PUMP SUCTION WILL AUTOMATICALLY RE-ALIGN FROM THE RWST TO THE CONTAINMENT SUMP. BASED UPON REFERENCE 1, A MINIMUM DEPTH OF 2.SFT (SMALL BREAK) OR SFT (LARGE BREAK) OF WATER IS REQUIRED IN THE CONTAINMENT SUMP TO PREVENT UNACCEPTABLE VORTEXING. THE WORST CASE FOR INITIATING AUTOMATIC SWITCHOVER IS THAT THE RWST LOW LEVEL SETPOINT WAS ACTUATED ON THE HIGH SIDE DUE TO POSITIVE INACCURACY OF THE RWST LEVEL INSTRUMENTATION. THEREFORE, IF THE PERMISSIVE SIGNAL FROM THE CONTAlliMENT SUMP LEVEL INSTRUMENTATION WERE ACTIVATED BELOW ITS SETPOINT, AUTOMATIC SWITCHOVER WILL NOT OCCUR UNTIL THE RWST LEVEL DECREASES BELOW THE RWST LEVEL INSTRUMENT SETPOINT PLUS POSITIVE INACCURACIES. HOWEVER, WHEN THE RWST LEVEL DECREASES.TO THIS LEVEL, THERE WILL BE A MINIMUM DEPTH OF 3.65FT (SMALL BREAK)
OR 12.4 FT (LARGE BREAK) OF WATER ACTUALLY MEASURED BY ABOVE THE CONTAINMENT SUMP IRRESPECTIVE OF WHAT IS THE CONTAINMENT SUMP LEVEL INSTRUMENTATION, AND NO PUMP DAMAGE WILL OCCUR DUE TO VORTEXING. THE ONLY EFFECT THE CONTAINMENT SUMP INSTRUMENT SWITCHOVER LOOP INACCURACIES WILL HAVE ON THE AUTOMATIC LOGIC IS THAT IT COi!LD GENERATE A . PREMATURE PERMISSIVE SIGNAL FOR SWITCHOVER. HOWEVER, SWITCHOVER WILL LOW RWST NOT OCCUR LEVEL. UNTIL THE "AND" LOGIC IS MADE UP BY THE "AND" LOGIC AS DISCUSSED PREVIOUSLY, ONCE THIS IS MADE UP THERE WILL BE THE REQUIRED 2.5FT -
(SMALL DREAK)

- IN CONCLUSION, THE INACCURACIES IN Ti!E INSTRUMENTATIONNEGATIVE DIRECTION FOR THESE OF THE CONTAINMENT SUMP LEVEL TWO SCENARIOS WILL NOT INITIATE SWITCilOVER WITl! INSUFFICIENT WATER IN THE CONTAIliMENT SUMP. ,

NOTE 4: NOTE PER REFERENCE 20, THE MINIMUM EXPECTED LEVEL IN THE CONTAINMENT SUMP FOR A LARGE BREAX LOCA IS 12.4FT. '
THE CONCERN TO BE ADDRESSED WITH RESPECT TO THE UPPER !
SAFETY LIMIT IS THAT SWITCHOVER IS NOT PREVENTED DUE TO ;
POSITIVE INSTRUMENT INACCURACIES. SO, THE MINIMUM i EXPECTED LEVEL WILL BE USED AS THE UPPER SAFETY LIMIT TO PROVIDE FOR THE MOST LIMITING CONDITION. (12.4 FT - 0.5 FT) = 11.9 FT OR 11.9'/20' = 59.5% OF SPAN.

EA E E AND ACCURACY REOUIREMENTS FOR THE CONTAINMENT SUMP HIDE RANGE LEVEL INSTRUMENTATION -
- 1. Accuracy Reautrements The PA'1 accuracy requirements for this variable are specified in DNE Calculation SQN-0SG7-0040 " Containment Sump Level Instrumentation Post Accident Monitoring Accuracy Requirements".
- 2. Rance Reauirements The containment sump level instrumentation should be capable of measuring from 0% level to the maximum expected flood level. Note 5 of ,
Environmental Data Drawing 47E235-45 states the maximum surge level of the containment water level is elevation 698.8 ft. and the maximum steady , state level is 694 ft, for Unit I and 694.5 ft. for Unit 2. DNE/NES calculation SQN-SQS4-0138 states the level instrumentation lower tap is 0.5 f t. above the bottom of containment sump and extends up to 20.5 feet above the containment sump bottom. This provides a range in elevation from 680.28 ft. to 700.28.ft. thus encompassing the maximum surge level with an approximate 7% margin to prevent pegging. The Reg. Guide 1.97 - recommended range is-bottom of containment sump to 600,000 gallon water level equivalent. Using the formulas and data of calculation SQN-SQS4-0138, the volume in containment sump at the existing upper instrumentation limit is 577,763 gallons, which meets the intent of Reg. Guide 1.97 requirements. Therefore, the recommended instrument range is from elevation 680.28 f t, to 700.28 ft.

The 100 dav accident gamma dose was calculated from.TI-RPS-48 F0. The beta ccse'given in TI-RPS-48 was ad,iusted to eccount . i or .a ' fantte <olume in thw raceway.

After a LOCA, containment temperatures no will have subsided within 30 days such that containment spray is longer needed. Therefore, these instruments are required to be Category A for a LOCA for 30 days and are not required (Category, C) af ter that time. For auxiliary building events, these temperatures are not used; further, incorrect ,, indication would not interfere with operator diagnosis of auxiliary building events. Therefore, these instruments are not required. for the auxiliary - building events. p containment Sump Water Level (WR) Instrument Event Category OP Time LT-63-176 L A 177 100 days MS/C A 100 days 178 FW/C A 100 days 179 RH/C A 1 month CV/C A 1 month Justification g High containment water level readings alert the operator to a 8ELB inside containment and assist him in identifying the type of HELB (all events).

ABBREVIATIONS - 13.1 Allowable Value (AV) - AV is defined as the analytical limit (AL) minus the difference between the Design Basis Event accuracy band (Adbe) and the normal i measurable accuracy band (Anf), which does not consider calibration unmeasurables (i.e., waterles errors, process errors, etc.). It is reasoned that following aaIdesign basis event that the output of an instrument may change by the difference between the normal and design basis bands. { Therefore, if the output exceeds the AV value during normal operation, the analytical limit would be exceeded if to design basis event occurs during this time (See subsection 15.7.4.1 notes 1 and 2). 1 g AV = AL - ( Adbo - Anf) The details of the calculations for these errors are included in Subsection 15. . p 13.2 Acceptance Band (Ab) - During calibration or calibration checks, the required
/ deviation from the true value deemed acceptable without requiring readjustment. (An acceptance band should be selected such that the
. instrument inaccuracies fall within the band.) Ab should never be less than '
reference accuracy. " Rule of Thumb"-Ab = 11 (Reference Accuracy) [ 13.3 Accident Accuracy (Aa) - Accuracy of a device in a harsh environment caused
- by an accident (excluding a seismic event).
13.4 Bias Error - The difference between the average of the measurement population and the true value. In this standard, a bias error is as error that has ai certain fixed value for a given instrument under specified conditions. The exact is known. value of the fixed, error is unknown, however, the range of uncertainty 13.5 Confidence Interval - The bounds about the measured value within which the true value is believed to lie. 13.6 Drift - An undesired change in the output over a period of time. This change is unrelated to the input, environment, or load.

It appears that 11 (Lasulation resistance) asasurements were # not conducted tu,gigg,the LOCA test of Westinghouen canister ! eteatrical penetrastese. If this is the case, how do you kaev i that ihstrumentaties circuits will perform se required 7-~ ~ Rennennet The test report (pp-RL1-26-73 binder page D-15) states that ) the lowest l IR asasured during the test was 2.5 x 10 shes got i 4 30 conductors and af ter the test 29 had better than 6 a 10 ' obas for the la AMG instruneatation conductors (page 0-17). ; The report states the It asasurements were takaa every neur ' during the LOCA test (page D-17). se further detail with respect to IR asasurement is gives in the test report. t Since the Its asseured were acceptable, it is apparest to i perassent damage had takaa place. The primary cause of It i j degradation during peak accident conditions is due to asisture permeating through the pigtail sonductor jacket /issulation ! systes. Some 13 drop may also occur due to sciature permeating through the epory petting to the.isternal pigtail sonnectica l area but this is salikely due to the meisture resistance sad . thickness of the pettlag. Desage to the opeuy petting / sealing ' systou toads to be permanent and would be evidensed in the 11 or leak rate testing. There is se evidence, therefore, of peraament damage. '!be only other area of concern is the penetration pigtails. The 8eguoyah pigtails are separately qualified by tests that includsd IR tests during test

( 2G NIQ.PtWE.00ll) (Continued) The Category I!! cables associated with these penetratiens (M8 , l s.nd instrumentaticn level cable) can be divided into three basio groups based on the end devices. ; g Dayina.Funation , 1 Switches 2 Transmittore 3 PTDs and Acoustic honitora The sinisq insulatten resistgnce measured in any of the LOCA tests k was 2 5 x510 x {0 ohasfor ohns (the 20 0.5 feetx for to ohns/1000 ft can be converted a typical per.etrattori to application). The effect of this IR on switch circuits is negligible since the , voltage and current are relatively high. The effect on the i
' acoustic monitoring circuits is also negligible. See EQ Binder 7 l SCNEQ.!!T 001. The effect on transsitter and RfD oircuits can also l 1 be shown to be negligible se demonstrated below. .
l The methodology used in OE calculation 50N-107 39 can be used to I eh1.- L i evaluatt the effect of this IR value. Note that the test lonath and the installed length are the same and therefore, the IR value i is not adjusted ,for cable length. For transsitters, substituting the IR value of SM ohma the effective IR is 5M + SM ohns : 10M ohns. AT 500 VDC the leakage current would be : 500 V/10M chas = 0.05 mA , AT 73 Vf4 liasisua leakage would be l (73/500) x 0.05 mA e 0.0073 m( l t PAGFo-"/S* , 1 TVA 19537 40E.3 8el *PE .8. h A9 Ib b0 h Nh33h h&ld hhh}/d/N

The sero output of the differential pressure transmitter, s/NtC6431 in five ($) feet of water for 14 days is within 10.25% FS (See Table 6-1 of statham Engineering Report 0648-a4-200-NUC-0711). The accuracy of the transmitter after submergence testing is within 10.25% FS (See Table 6-3 of Statham Engineering Report 0648-W4-200-NUC-0711). h e Full Scale output of transmitter 3/NIC6432 which apparently shifted 1.5% FS during submergence testing was due to span pot movement during test set-up. It is a handling error not related to submergence performance. should you have any further questions, please do not hesitate to contec: the undersigned. , Best Regards, hJ M V David No Senior Engineer - I7 cci P.tesoren.

IA study of the water level in the containment sump following a large t ILOCA was performed. This study used assumptions that are conservative I trelative to minimum water level. The'resultssof the study show that thet Iminimum water level occurs for a break located at the reactor vessel t-Inozzle which floods the reactor cavity. At the initiation of switchovert
'lto the recirculation mode (RHR pumps realign to the sump) the minimum 1 Rf twater level will be 12.4 feet (el 692.20). At the completion of I lewitchover (CSS pumps realign to the sump) enough additional water wi11 1'
({ { thave entered the sump to bring the %ater level to 15.9 f eet (el 695.78) l' ISome of this water will flow through the unsealed penetrations in .the I tcrane wall above el 693.0. Therefore, at the onset of switchover the I twater level will be below the 13.2 foot level, but will increase to at t, lleast 13.2 feet at the completion of swi tchover . 1 I -

FM' 1.0 PURPOSE AND BACKGeOUND 1.1 Purcess The purpose of this calculation is to determine the mininum water depth in the active containment sump at the time of switchover to the recirculation '
mode following a large break LOCA (LBLOCA).
4 1.2 Pachmecund Following a LOCA. steam and het tJter from the break cause a rise in temperature and pressure in containment as well as a loss of primary coolant. The engineered safety systems actuate, supply 1ng cooling water to the reactor and coolant system (RCS) from the cold leg accumulators (CLA) the refueling water storage tank (RWST) and the containment spray system to containment through (CSS) from the RWST. Ice in the ice condenser also melts.
The CSS sprays water into the upper compartment atmosphere through nozcles in two spray headers to help ensure that containment pressure temperature do not and exceed design values.

- 2.0 ASSUMPTIONS [
- , 0.1 Maximum flow rates are assumed for all pumps taking' suction-from the I RWST. This is conservative since it mintmt
- es the time to switchover by has t er.i ng the depletion of the water in the RWST. The shorter time to i switchever minimizes ice melt.
2.2 All technical specifications were conservatively chosen to minimi:e the water level in the containment sump. (i.e.. RWST level is at minimum- i
, full at the onset of the event and at-the h1gh level limit of setpotnt at ;
o switchover.) -a r 2.3 The water held up in the upper compartment has reached equilibrium. ,
(i . e. , The water flowing into the refueling canal (RFC) equals the water draining from the refueling canal to the lower compartment.)
2.4 All penetrations in the crane wall below el 693.0 feet are sealed.
(See references 9.1.10 and 9.19) l 2.5 Because the upper head injection system is likely to be removed in the.
- future, it was not considered as a water source. This is conservative relative to this calculation since it minimizes the volume of. water available for recirculation.
2.6 The pipes in the CSS are full of water up to the spray headers during- .
l normal operation. This is a reasonable simplifying assumption as tho' !
I addittonal water volume to fill the spray headers'is negligible relative l to the total water volume. ;
2.7 Water droplets from, the containment. spray will remain constant in l size. Since the CSS water warms the upper compartment atmosphere during the injection mode, and water condenses- onto c' col or surfaces, this assumption is conservative.
2.8 Due to turbu1'ence in the upper compartment atmosphere, assume CSS water homogeneous throughout.
l 2.9 Per Technical Specification, M!-1.0, SI-20,tand FHI-8 refueling covers will be removed and the vor t e:t suppression devices (normal operating covers) will be in place whenever the plant is in operation.
2.10 Flow into the reactor cav'ity.through the neutron monitor windows is negligible (ref erences 9.1.11, 9.1.12, 9.1.13). -
~
2.11 An allowance of 0% for equipment volume between el*679.78 feet and-el 690.0 feet is conservative relative to minimum water level. This 0% is i t based on the engineeFing judgment of Robert S. McKeehan and Edward J.
, Sheehy. This allowance is not used for the sump pocket, the refueling anal or the reactor cavity since they do not contain equipment. '
2.,10 Screens provided on drains from accumulator rooms ; and 4'are properly sized to assure flow into the sumo (reference 9.1.14).

0.13 Per reference 9.17, the extensions to the vertex suppressors an the RFC drains arg in place in Unit 2. They are assumed to de-sn place in Unit 1. Thiw is conservative since it maxim 1:es water held up in the refueling canal.
O.14 All CSS water falling onto the reactor enclosure in the upper compartment is assumed to flow to the operating deck. This is a simplifying assumption which is conservative since it massim1:es the watee volume held up on the operating deck.
O.15 The decrease in flow rate from the RWST from 20,900 gpm to 9,500 gem is linear with time for the two minutes it takes for the valves to close (reference 9.5). This is a simplif ying assumption.

5.1 Water in the Uccer Comoartment (UC) Atmoschere Water sprayed by the CSS which has not yet fallen to the ccerating dacP is not avail abl e to the containment sump. The amount of _ this unavallatla water is a function of the droplet sica, the vertical velocity.-and the drag force exerted on the droplet due to the resistance cf the uccar compartment atmosphere.

At equilibrium flow, all the spray not going directly into the refueling canal -(RFC) will be assumed to fall onto the operating deck (CpDk) before flowing into the RFC. Spray is assumed to be evenly distributed ever the entire area inside the crane wall. Therefore, the flow rate of the portion of the spray falling onto the operating deck will be cetermined as the ratio of the area of the operating deck to the total area multiplied by the total CSS flow rate.
Q(OpDk) = (CA(total) - A(RFC-!CW)3/A(total))C(total) j Q(OpDk) = Q(Total)C1 - A(RFC-ICW)/A(Total)3 Q(OpDk) = (9,500 gpm)C1 - 509 sq ft)/5,411 sq ft3 = 8,606 gpm The length of the flow, L, is equal to the perimeter of the RFC in contact with the OpDk. Therefore, L= 104 ft.
It is conservative to assume that all water from the reactor enclosure 1 f alls onto the OpDk.
Solving for h, the above equation becomes h = CQ/(0.30L)3
- h= ((8,606 gpm) (min /60 sec) (cu f t/7. 48 gal) /C (3.30) (104 ft)3[*
(10 in/ft) h = (.145 ft)(10 in/ft) = 1.74 in The total height of the water held up on the operating deck then is h(total) = h(curb) +h = 2 in + 1.74 in = 3.74 in ,
The volume of water held up on the operating deck is (2,442 sq f t) (3.74 in) (f t/12 in) (7.48 gal /cu f t) = 5.690 gal V(OpDk) =

The air return fans start to minutes after the containment spray begins.
Therefore the volume of water entrained by the f ans and deposited in the accumulator rooms at automatic switchover is V= (140 gpm)(11.20 min - 10 min) = 171 gal The additional water deposited in the accumulators at containment spray realignment is VA = (140 gpm)(6.02 min) = 843 gal Both of thase amounts are negligible and will not be considered in this calculation.

For this case, the water discharged will flow into the containment sumo.
A small amount of this water will-flow into the reactor cavity through the small annular areas of eight instrument penetrations at each of two levels, elevation 680.79 feet and, elevation 686.78 feet. The amount of this flow is negligible (assumption 2.10). .
