219B-071 Rev. $ . Based upon this review we have noted the following discrepancies:

(a) On page no. 24 vf the above calculation, applied forces and momeilts are computed at center line of the spdce (Point B) as follows:

Fxb = Fx/2 sides = 7,798#

Fyb = Fy/2 sides = 8,971#

Fzb = Fz/2 sides = 6,$77#

The above forces are discrep* '. because they do not include the contributions from the applied moments at pipe center line.

The correct forces ara as follows:

Fxb = Fx/2 sides a 7,798# ( No Change)

Fyb = Fy/2 sides 4 Mz / 2Lz = 9,580#

' Fzb = Fz/2 sides + My / 2Lz = 7,078#

(b) On page no. 29, the allowable shear for 1" Diameter A 325 SC bolts used is 13.40 k. This is in error. The bolt allowable shear should be based upon Shear Tension interaction for slip-critical connection per section J.3 of AISC manual,9th edition.

The correct value is 6.58k.

These valves are shown on P&lDs EM 104A Revision 26, EM 112A Revision 25, and EM-113A Revision 14.

According to FSAR Section 7.3.1.1.5, valves 3CHS*1120 and 3CHS*112E shall be interlocked to open on a safety injection signal (SIS). However, these P&lDs show no interlocks between SIS and these valves. Furthermore, the P&lDs shows no controls for 3CHS*1120 and 3CHS*112E.

NU has concluded that DR MP3-0084 does not represent a discrepant condition. P&lD EM 113A, Revision 17 and EM 104A, Rev 32 provides a cross reference to PalD EM 104D, Revision 20, dwg. locetion D 11 that show the controls and interlocks for valves 3CHS*1120 and 3CHS*112E. This section includes all controls and signals that these two valves receive and is consistent with FSAR section 7.3.1,1.5. Additionally, the latest revision of EM 112A is Rev 32 not Rev 25 as Indicated on DR.

MP3-0084 and valves 3CHS*112D and 3CHv112E do not appear on the current revision of EM 117.'..

Conclusion:

NU has concluded that Discrepancy Report DR MP3 0084 does not represent a discrepant condition. As detailed in the disposition, the proper controls and interlocks for valves 3CHS*112D and 3CHS*112E are indicated on EM 104D, Rev 20 which is cross referenced by both EM 104A and EM 113A.

Valves 3CHS*112D and 3CHS*112C are not indicated on the current revision of P&lD EM 112A. Current revisions of EM.

Drawing 1217's-EM 104D Revision 16 does show controls for the subject valvt* '.id shows that the valves open on a safety injection signal. The discrepancy is that drawing 12179 EM-104A Revision 26 does not show any control information for valves 3CHS*112D and 3CHS*112E and does not cross reference drawing 12179 EM-104D Revision 16 or drawing 12179-EM 113A.

A review of drawings P&lD EM 113A, Revision 17, dated 12/22/97 and EM 104A, Rev 32, dated 11/3/97, show the coiTect cross references.

Consequently, this discrepancy report is valid and the implemented change to P&lD EM 113A Revision 17 is an acceptable resolution.

In the event of a high temperature in the retum duct to the MCC and rod control area air handling unit, or an Loss of Offsite Power (LOP), the pumps will automaticall/ statt if the associated air conditioning unit is operatir$g ."

This description does not match the schematic and logic drawings. Based on the drawings the pumps will not start if booster pump suction pressure is low for greater than 20 seconds along with the conditions defined in the description.

This was verified by a reviow of the following drawings:

INVAll0:

Date: 2/19/98 RESOLUTION: NU has concluded that the issue reported in Discrepancy Report, DR MP3-0175, does not represent a discrepant condition. The MCC and Rod Control Area air conditioning units are normally supplied with chilled water from the chilled water system.

l DR No, DR MP3 0176 Northeast Utilities ICAVP Millstone Unit 3 Discrepancy Report ,.

Dackup cooling to these units is provided by the service water system. Specifically, two independent booster pumps provide service water to these units under the following conditions:

On LOP signalif the cooling units are running, OR On high I.imperature in the retum duct to the MCC and rod control ares air handling unit if the unit is running.

The above information is reflected in the design basis and appropriately reflected in the lleensing basis as described in the FSAR. The additional feature in the design which shuts off the booster pumps if there is not sufficient suction pressure for 20 seconds is provided for equipment orotection only since one booster pump will always be available for a transient condition.

Specifically,if one assumes a single failure of an electrical train, the other train will be available and it is not necessary to postulate a second f ailure associated with the booster pump suction pressure.

In summary, the logic diagrams and the FSAR have been reviewed and it has been concluded that both are consistent and correct and no further action is required. it should also be recognized that in the overall context of the FSAR it is not necessary to discuss every design feature of a system, particularly when the discussion does not Impact the safety analysis.

Significance Level criteria do not apply here as this is not a discrepant condition.

Conclusion:

Nu has concluded that the issue reported in Discrepancy Report, DR MP3 0175, does not represent a discrepant condition. The low suction pressure for 20 seconds is a trip of the service water booster pump not a start permissive. In addition, the trip is for equipment protection only. The automatic starts of 3SWP*P2A/B are well described in the FSAR and accurate. In the context of the FSAR,it is not necessary to discuss every design feature of a system. Significance Level criteria do not apply here as this is not a discrepant condition.

Description:

During the review of component data for the Emergency Generator Enclosure Ventilation System supply fans 3HVP*FN1 AltB/1C/1D discrepancies regarding the fan model number, motor nameplate rating, and fan total pressure rating were identified.

FSAR Section 9.4.6.2 states that each emergency generator enclosure supply fan provides 60,000 cfm of supply air.

Specification 2170.430-140 indicate that the fans are Buffalo Forge model number 48B5 rated at 60,000 cfm and 2.95 ive total pressure. The f an horsepower requirements at the rating point is 37.2 hp. The fan motor data sheet contains conflicting information on the nameplate rating of the motor Under horsepower by fan mfg; it states 60 hp, while in the column that contains performance data for the motor it Indicates that the motor has a 40 hp rating.

The Plant Design Data System (PDDS) database indicates that the f an brake horsepower required is 38.5 hp and that the motor has a 40 hp nameplate rating.

The vendor drawing for the fan,2170.430-140-100, states that the fan is a Buffalo Forge model number 48B9 rated at 60,000 cfm and 2.5 iwg total pressure with a 60 hp motor.

The fan performance curve dated 6/21/82 for the fan states that the fan is a Buffalo Forge mode! number 48B5 rated at 60,000 cfm and 2.95 iwg total pressure.

Date Published: 10r23/97 Discrepancy: Calculation P(R)-1020 D!screpancies De6cription: Calculation P(R) 1020, Rev. O," Verification that RSS Pumps have Sufficient Head to Provide Containment Sump Water to SSP System for Sampling." The calculation uses the pump head and the piping friction losses to estimate the flow rate to i

the sampling system during Recirculation Mode. The flow rate l

through the sample system is required to be between 0.3 and 1.0 i gpm. The calculation concluded the flow rate should be approximately 0.75 gPm.

j The length of pipe from the pump to the cooler included only the '

vertical piping and the fittings. The horizontal piping is approximately 50% of the length of the vertical piping. This results in an additional 1 psi pressure drop and decrease the flow rate.

The length of pipe from the cooler to the 8" x 10" reducer j

included only the horizontal piping and the one tee. The vertical piping is approximately 100% of the length of the vertical piping and there is another tee. This doubles the resulting head loss and decreases the flow rate. i The dP coefficier.t (0.000216) was incorrectly transposed f j

(0.00216). The result reflects the correct coefficient was used in )

the calculation.

The length of 8" pipe is given as 103.75 feet. A review of the I references indicates only about 72 feet of pipe. This decreases i the head loss and increases the flow rate. l The sample lines are tubing. Tha ielative roughness for tubing is j

.00013 resulting in a friction factor of 0.028 which is less than O.037 used for the same size pipe. This decreases the head loss and increases the flow rate.

The dP from Point D to E is incorrect. The value of 0.18 psi was included in the equation as 0.018. This value was carried throughout the calculation; however, because of its size compared to the overall pressure drop (174.1 psi), it has no impact on the results.

The equation to calculate the angle for a reducer is incorrect.

The angle is based on half the diameter iifference and the length of the reducer. The equation uses half the length of the reducer. This overestimates the head loss and increases the flow rate.

ICAVP DR No. DR-MP3-0337 Northeast Utilities Millstone Unit 3 Discrepancy Report for K. The numbers were not transposed correctly; however, the results reflect the correct number.

The approach indicates that the losses will be calculated across Train D. Trains A, B and C have 16' X 10' Reducers at the outlet of the Coolers. Train D has a 16' X 10' reducing flange.

This is better approximated by a sudden contraction. This does not impact the overall results of the calculation.

The dimensions for the sample lines could not be confirmed.

The referenced drawings did not have all the dimensions nor were the drawings legible. Any gross overestimation of the tubing length will be offset by the conservatisrn used by assuming a higher friction factor.

The calculation states, "No pressure drop is associated with elevation since the water being pumped starts from and retums to the same place." However, the calculation starts at the pump discharge and ends at the end of the sample line. The sample line drains into the sump. Since the dimensions and elevations for the sampic lines could not be verified, the elevation loss cannot be determined.

Overall, the comments associated with this calculation do not appear to affect the conclusions of the calculation.

Date Published: 11/1W97 DisCf*Pency: Calc. 90-0691116-M3 rev. O through CCN 02 contains several unaddressed issues.

Ducription: Calculation 90-069-1116-M3 rev. O through CCN 02 determines the Service Water System (SWP) minimum available cooling water flow rates under design basis accident scenarios. This calculation uses the Westinghouse PEGISYS SWP model. The following discrepancies were noted in this calculation:

1. A nodal diagram is needed to verify the inputs and outputs of the PEGISYS model. However, there is no nodal diagram included in the calculation. Thus the PEGISYS outputs (results) can not be correlated to SWP system components.

2. CCN 02 dated 5/27/97, states on the enver sheet that calculations NM-061 SWP, HYD H9, HYD-H10 and 12179-2330.110 are superseded by this calculation. On page 2 of this CCN, calculations P(T)-1005, P(T)-1092,3-ENG-164 and NM-021 SWP were hand written in following the above calculations.

- Pages 3-5 of this CCN does not included these four additional calculations as being superseded. It is unclear whether or not these additional calculations are superseded by CCN 02.

3. CCN 01 dated 3/31/97, stetes at the bottom of page 2 that this calculation is SUPPLEMENTED by calc. 90-0691097-M3, rav. O through CCN 02 which contains the latest service water PEGISYS model. Calc.1097 was not one of the references that were added by this CCN. It is not documented what affect this latest model will have on the results of this calculation. The model should have been re-run to verify that the system changes incorporated by calculation 1097 were included and the resultant minimum flows did not change adversely as a result of the model revisions.

4. Pages 47 and 48, state that the surveillance limits for the CCP heat exchanger and the HVQ ventilation units were reduced from 19 to 15 psid and from 6 to 4.5 psid respectively. There is no justification stated or documents referenced to quantify how these ney; limits were derived. The surveillance curves in procedure SP 3626.13 reflect these values, however, the calculations that develop the surveillance curves (cales. 90-069-778GM and 90-069-776GM for CCP and HVQ respectively) still maintain the original surveillance limits. Calculations -778GM and 776GM were not superseded by CCN 02.

5. Page 49 and 50 contain the table that summarizes the results of the PEGISYS runs. There is no conclusion stated that validates or invalidates the values listed. The margin in some t nene le nanntlug ~

6. The PEGISYS output for all the cases evaluated is included in this calculation. There were several cases in which the output stated that the pump flow rates exceed run-out. This occurred for the cases titled: case (page 78), case 5cep (page 280) and c5cepa (page 406). This was not addressed in the body of the calculation for acceptability of the model results. This could impact the results of this calculation and any other document that references these results.

The overall affect of the discrepancies noted for calculation 90-069-1116-M3 rev. O through CCN 02 can not be determined without revising the calculation.

Description:

Reviaw of calculation 95-ENG 1177 M3 Rev. O through CCN 01 identhied the following discrepancies:

1.) The calculation uses design inputs which are documented inclusively in calculation 90-0691130-M3. However, Design input #6 of the calculation (95-ENG-1177) references a portion of calculation 90-069-1130 M3 which has been superseded by calculation 95-ENG 1177 M3. Therefore, no valid reference for design input #6 is documented in the calculation.

2.) Design input #12 is based on Reference 6. However, the number of passes in the heat exchanger is not contained in Reference 6.

3.) Assumption 1 of the calculation,"no subcooling in the condensor", contradicts the 8 'F of subcooling assumed by the vendor suppling the heat exchanger data as documented in Reference 6, Attachment 1, item 7.

4.) No reference orjustification for the Correction Factor, F=1.0 for the heat exchanger is documented in the calculation.

These discrepancies are not expected to have a significant effect on the calculational conclusions.

Prior to start up design pressures and temperatures for systems were stated on the system flow diagrams (FSKs) and listed in the line designation table (LDT), Design pressures and temperatures, along with their reference, are also stated in the stress data package (SDP), The FSKs have since been retired but the values remain in the LDT and SDPs. The SDPs have been reconciled with system calculations under the 50.54(f) effort. FSK 9-10J (retired) inoicates a design pressure of 145 psig for the lines on the discharge side on 3SWP*P3A&B. SDP-SWP 01370M3," Service Water Stress Data Package" page 29 of 71 states that " isolated sections of piping in the service water cubicles, control bul! ding, and ESF building have a design pressure of 97 psig for hydro test reasons.

Dele Publishad: 11/1597 D6screpency: Calculation 92 0801014ES Incorrectly Applied Hydraulic Data

Description:

The purpose of Calculation W2 0801014ES was to evaluate ),ow rete changes in the 3HVQ' ACUS 1B and 3CCI'E1B piping lines as a result of modl0 cations made by DCN DM3 S 034 93 and DCN DM3-S 0050-93 The approach taken was to evaluate the form loss coef0clent, K, before and after the modifications to predict changes in the flow rates. Table 1, page 7, identifies the tJD for all of the components in the 3HVQ' ACUS 1B line before and after the modl0 cations. The values listed in the UD coluren cre actually the values of K, where K = f*(UD). This error is propogated all the way through the calculation such that changes in K are being compared to changes in UD, which are not meaningful and probably not intended.

The 'Altemate Check Calculation'(included as Attachment A) assumes the information in Table 1 of the original calculation is correct and uses it in the attemate check calculation without verifying it. The change in the form loss coef0cient, detta K, for the 3HVQ' ACUS 1B branch is calculated on page A2. Here delta K is determined by multiplying f times delta UD Since the referenced delta UD value was actually detta K, multiplying it again by f Inv:lidates the results of the calculation as this error is propagated through to the final result.

The percent UD reduction for the HVQ branch was Incorrectly determined to be 0.09%. Had this analysis been done correctly, the percent UD reduction for the HVQ branch would have been approximately 5% and the percent UD reduction for the CCl branch would have remained as 4%. Therefore, the conclusion that percent UD reduction for the HVQ is less than the percent L.iD reduction for the CCl branch is incorrect. The difference between the two branches is minor (5% vs. 4%).

Date Put>h6hed: 1VM97 Dacrepency: Insufficient reference and incomplete methodology identified in Calculation 88-BOP 677 GM, Rev 0.

Description:

The purpose of calculation 88 BOP-677 GM. Rev 0 was to analyze the effects on the Millstone Unit 3 service water system after replacing certain short radius small bore pipe elbows with 4D and SD pipe bends located in the HVQ, CCI, and CCE portions of the system.

The approach taken by this calculation was to multiply the difference in the 1/D values for the affected lines before and after the modifications by the worst case flow to predict the change in pressure drop.

The worst case flow rates were taken from Reference 6, Millstona Ur.;t 3 Service Water Phase I & 11 Test Report. The worst case flow rates usod in the calculation could not be verified because the reference is insufficient. Reference 6 does not include a date when the tests were condus *1d nor does it include a number to identify it.

Assumptions and approximations are made in the calculation to determine the 110 values for the affecteo lines before and after the modifications. The methodology section does not indicale what assamptions and approximations will yield conservative and non conservative results. For example, it is not clear if an assumption that ovsr estimates llD for the pre-modifications condition is conservative or non-conservative. An approach to determine conservative llD values for pre and post modification conditions should have been established.

Page 12 of the calculation contains a sentence that trails off:

"These slightly larger pipe ID's are not expected to cause . ? ?

The discrepancies identified in the calculation are not expected to effect the conclusion of the calculation that the modifications will have an insignificant impact on the service water system operation.

Date Published: in?697 Discrepancy: Required component flow rates in Calculation 17273.161P(T) were not able to be verified oescript6on: The purpose of Calculation 17273,1tr1P(T) was to predict Individual component flow rates in the service water system using degraded service water pump conditions and compare them to required flow rates established from several referenced sources.

The approach taken by this calculation was tc use the HY 06C hydraulic model, using the degraded pump curves, to predict the flow rates to several components in the service water system.

The predicted flow rates were then compared to required flow rates referenced from several sources.

The required flow rates for tiie components analyzed are shown on Page 43 of the calculation along with their respective references. These references were not incicded in the Reference Section of the calculation on Page 4 of the calculation.

The referenced required flow retes identified on Page 43 could not be verified for (3) reasons. The first is that many of the references have been superseded. Referenced calculations 90-FAC-094GF,12i?9-P(T) 1100 and P(R) 1168 have been s.perseded. The second reason !s that the required flow rate was not referenced from a particular operating condition, References, such as the FSAR, contain several required flow rabs for a component under differer.t operating conditions. And lastly, the comparison does not Indicate the quantity of each component operating when comparing the required flow rate and model predictions. For example, is the required flow rate for the CCP heat exchanger based upon 1,2 or 3 operating, and are the predicted flow rates for the CCP heat exchanger based upon 1,2 or 3 operating so a direct comparision can be made?

The discrepancies identified in this calculation are not expected to impar:t the results of this calculation or the functionality of the service water system, in fact, the objective of ;his ca.lcu!ation is also addressed by calculation 90-069-1116 M3 using the PEGISYS hydraulic model to demonstrate minimum component flow requirements will be met.

NU has concluded that Discrepancy Report DR MP3-0462 represents a discrepant condition not previously identified, in that Calculation 17273.161P(T), which is no longer the calculation of record, was not identified as superseded or volded, and other calculations referenced within are now out of date. Conditlen l Report (CR) M3 97 3897 has been approved to correct this condition. The new calculation of record is 90 069-1065M3, Rev. O, dated 10/06/94, *MP3 Service Water System . NRC GL 6913, item No. IV Design Basis Summary Report?

Implementation of this change did not identify P(T) 1 as canceled or superseded.

Calculation 90-0691116M3, noted by S&L in DR MP3 0462, was prepared as Westingheuse Calculetion FSE/SS-NEU 1956 to determine minimum available flow rates during accident scenarios. This portion of the calculation has been superseded by calculations PROTO-POWER 97 035 Rev. O dated 08/14/97, PROTO-POWER 97 041 Rev. O dated 09/05/97 and 97 ENG-01427D3, Rav. O. This change was documented in CCNs 1 through 6 of Calculation 90 0691065M3 Rev. O.

As part of the corrective action for condition report M3-97 3897, service water system design basis flow calculations will be reviewed to verify that no references contained therein have been volded or superseded. With reference tc steps 5.2.6 and 5.3.4 of the Desion Control Manual, which require a review of child or parent interactions when preparing changes, item 4 of the corrective action plan requires that a siniilar change be made to Section 6.1 of the DCM to direct the same review when superseding or volding calculations.

Difficuttles in determininq required and available flow raus, as identified by DR MP3 0462, have been corrected by the revisions described above. The remaining corrective action is to revise Calculation P(TF1 to identify that it is volded or superseded. Based on calculation 1065M3 being the calculation of record, the discrepancy a sociated with not voiding calculation 1P(T) is considered an administrative issue, and as such, NU considers this a Significance Level 4 issue.

Calculations PROTO-POWER 97 035 Rev. O PROTO-POWER 97 041 Rev. O and 97 ENG-01427D3 were sent to S&L on 10/24/97 in response to RFl MP3-0641.

Date Published: 11/E97 066crepancy: Calculation P(T) 0938 rev. O has several inconsistencies.

Descriptkm: Calculation P(T) 0938, rev. 0 ' Service Water System Flow Balancing for Normal Operation" determines the butterfly valve throttling positions and orifice size for balancing the service water system in the nomial operating mode.

The piping referenced in this calculation is class 158 (ref 9). For 24" and 30" class 158 pipe, the well thickness should be 3/8" thick. This would result in pipe ID's of 23.25' and 29.25

respectively. This calculation uses 23.27' and 28,75' which does not coincide with the referenced document.

The factor DP/ttio is used in calculating c(d) (used to determine valve choking) for the outlet valve on pages 11,12 and 28. The values used for the f actor DP,rno are not consistent with the data noted and are not referenced. This questions the valid" the values being calculated.

The f actors DP (units of psi) and r" . (units of feet) are being interchanged in the analysis without account for the conversion factor between units. Thus the values used are not correct and the flow coefficients being determined are not correct.

The resistance coefficient for 3-way valves is not consistent with the referenced document. A value of k=10.21 is being used and a value of k=10.00 is noted in the reference 1. However, the value should be k=1.35 based on the document that reference 1 used as a basis, Crane Technical Paper No. 410. This affects the pressure drop being evaluated.

Page 29 references a pressure of 33 77 psl with an associated equivalent length of 142.02'. This value is not consistent based on the typical conversion factor of 2.32 ft/ psi which would yield an equivalent length of 77.19'. This affects the head differential that is determined using this value.

There were new nodes defined in this calculation that were to be incorporated into calc P(T) 935. This information was not included in P(T) 935 through CCN 02.

Due to the uying degree of the inconsistencies found throughout this calculation the overallImpact on the results can not be determined without re-calculating the model used.

Descr6pt60n: Calculation SDP SWP 01370M3, Revision 10, dated 5/23/97, This calculation is the stress data package for the service water system.

On page 29 of the s data package, the service water design pressure is notr .100 psig. However, calculation 714P(T) determines the so 'ce water design pressure to be 101 psig.

On page 29 of the c..culation a value of 145 psig is listed in the temperature and pressure table, with calculatic1, P(T) 1125 as the source reference. Calculation P(T) 11251,sts a value of 132.7 psig which appears on page 2. Therefore, there is a discrepancy between the value used in the stress data package and the referenced calculation.

On page 29 of the calculation, for 3HVR*ACU1 A/B discharge lines reference MCE SA 93 362 is cited for a temperature of 98'F. This reference does not show nor discuss the 98'F value.

On page 29 of the calculation, the temperature of 125'F was noted for the discharge piping of 3CCP'E1 A/B heat exchanger.

This temperature was referenced from ER 96-0326. This document was requested from NU and was noted as nct in NU system by IRF MP3-0496.

These discrepancies could impact the stress ar.d piping calculations that use this Information from the stress data packa08.

ICAVP DR N3. DR-MP3 0517 l Northeast Utilities Millstone Unit 3 Discrepaticy Report by NU which requires correction.

3. Reference giver. 'n RDP does not confirm 98F design temperature for certain lines.

The issue of adequate justification of pressures and temperatures used for piping analysis of the service water system was recognized and documented in CR M3 971598 dated 5/22/97 (attachod). The corrective action plan for the CR required reconsideration and update as required of all service water piping downstream of equipment.

As part of the corrective action, Enginect, ..,,M,a Correspondence 25212 ER 97 0242,1att d 10/27/r 7 (attached) was issued. The memo confirmed that'.ie 98F i ,nperature enveloped the operating temperatures. '.hanp' Notice #1 dated 11/27/97 (attached) to SDP SWP 01370Mdevision 10 incorporated the results of the memo.

NU has concluded that the issues #1,2 and 4 reported in DR M3-0517 are non-discrepant for the following reasons.

1. SDP states 100 psig as general design pressure, calc.

714P(T) gives 101 psig, in general, the Line Designation Table (LDD and SDP are the definitive source for design and operating conditions. The design conditions calculations were prepared as required to confirm that the selected design values were adequate. A strict correspondence from the calculations to the LOT is not required as long as there is no significant loss of conservatism.

The difference in pressure values between the LDT and the calculation can be attributed to differences in numerical rounding. T'-e calculation used a value of 1.03 for the density of seawater ans wived at a calculated pressure of 100.7 psig.

Using a more precise value for seawater density of 1.025 taken from the CRC Handbook of Chemistry and Physics (copy of page attached), the calculated value at the pump discharge would be 100.24 psig, which rounds to 100 psig and is consistent with the LDT The difference of 0.5 psig is insignificant and there is no need to revise the LDT. Therefore NU considers this item to be non-discrepant.

2. SDP states 145 psig as design for lines downstream of booster pumps, P(T) 1125 gives 132.7 psig.

The calculation determines a predicted pressure based on pump heads and elevation differences. The LDT design pressure is about 10% higher than the result of the calculation. 'is stated in the response to item 1, there is no requirement for a strict match between this confirmatory calculation and the value listed in the LDT The design pressure listed in the LDT is consistent with the

. relief valve 3SWP*RV132A.B setpoint of 145 psig for this piping. In accordance with the original S&W design procedure, the deslori;vessure must not be less than the relief valve Printed 2/239811:00.33 AM Page 2 of 3

ICAVP DR No. DR4AP3 0517 Northeast Utilities Mllistone Unit 3 Discrepancy Report setpoint.

Since the listed design pressure is consistent with the relief valve selpoir.t t'vl hinhar l'::..e the calculated pressure, NU considers this item to be non-discrepant.

4. Reference given in SDP was not provided to S&L A copy of the reference memo ER 96-0326 Rev.1 dated 2/23/97 is attached. Footnote 2 on page 2 of the memo describes the basis for the 125 F temperature listed in the SDP. The stated temperature has been reconfirmed in memo 25212 ER 97 0242 dated 10/27/97 (attached).

NU considers this item to be non-discrepant.

In summary of the above, NU believes that there is one discrepant item (#3) that has been pre discovered and three items that are non-discrepant. The pre-discovered discrepant item was corrected based on the action plan of CR M3-971598 and no further action is required. Further, the discrepancy of item #3 is with respect to documentation and not in Information used to satisfy the design basis of the plant. Therefore the discrepancy should be Significance Level 4.

Data was transposed incorrectly from laputs/ equation to equation 1 in various places throughout the calculation. i.e, Page 21 -

LMTD is noted in energy transport equation as 47.49'F, however, the LMTD is stated in the result table on page 15 as '

l 47.69'F. The density of seawater was noted as 64.15 lbm/ft3 at a temperature of 77'F based on reference K. Thl's referer.ce (page 68) refers to a density of 64,00 lbm/ft3 for seawater at 77'F.

The nomenclature used for the tube radius (page 7) contains incorrect units. The units should be ft not ft'.

Page 13 refers to reference Z in the calculation as the stress calculation, however this reference is the Generic Letter 8913 summary report.

The above noted discrepancies do not greatly impact the conclusions of these calculations. However, calculation 1037 evaluates the service water supplied to the Charging pump coolers at 78'F, calc.1036 evaluates the reactor component cooling water heat exchangers at 78'F, and calc 1038 evaluates the safety injection pump coolers at 77'F. There doesn't seem to be a consistent evaluation of the SWS components at elevated SW inlet temperatures.

The review of this calculation was limited to Duct 915, which l

{

The data for the cable at Row 1, Column 1 of Duct 915 is shown as a 3 conductor feed in the input data table on page A10-2, but as a single conductor feed in the computer run on page B10.

Since there is no retum feeder show,, the feeder is logically 3 r:onductor The effect of including the missing two cables will be to ralse the temperature of the cables in the duct bank, /,lso, the conductor resistance is listed as 52,5 microohm per foot on page A10 2, but is shown as 52.4 micoohm per foot on page B10.

However, this feed is very lightly loaded, so the additional heating will be slight, The valua of cable insulation thermal resistance til the 2000 MCM cable is not consistent between page A10-2 and page B10.

Date Published: 11/15/97 Discrepency: Dierepancies in Calculation #64E

• Cable Sizes for Feeders to MOVs*

Ducript60n: The review of Calculation #64E identified miscellaneous discrepancies lit the calculation. 'i he specific items are as '

follows:

1) Interoffler. Correspondence C-02 attached to the calculation identifies installed cable length: which differ from the lengths used in the calculation for the feed from the load center to the MCC, For the calculation of MOV feed ccble lengths from MCCs with a running voltage oN1v V (Table A), the cable length used in the calculation (page 3) is 479 feet. The installed length according to the memo is 550 feet.

2) Page 2 of the calculation identifies MOV ampacity as

.55(LRA @ rated voltage) as referenced in ETG IV 41. A review of the reference did not identify this basis.

3) Page 2 of the calculation identifies empacities for #12 and

1. 10 cables taken from IPCEA P-46-426. A revievt of the subject reference did not identify these ampacities.

4) Page 3 of the calculation identifies the bl;ek load of MOVs at 3 MCCs. Reviewing the latest revision of the one line diagrams for the affected MCCs yields values approximately 20 hp higher than those used in the calculation.

5) Interoffice Correspondence C-02 attached to the calculation states that page 5 of the calculation should reference

' Calculation #74E' instead of " Calculation #62E" as a basis for short circuit considerations. A review of Calculation #74E did not identify any basis for short circuit considerations.

6) A review of the calculation did not identify any basis for why the three MCCs analyzed in the calculation were chosen i.e.,

whether or not they are limiting. Also, no basis could be identified for th6 load current of the MCCs (150 A or 300 A) and it.e MCC running voltage (418 V or 422V).

7) On pages 13,14, and 15 of the calculation, no basis could be identified for choosing a grid voltage of 331 KV in order to determine the load center voltage.

Some of these discrepancies are non conservative; however, there are other conservatisms in the calculation which would ensure adequate sizing of MOV power feeds. Most notably is the conservative acceptance criteria for starting voltage of safety reintad MOVc Tha unVe nrn t nnnhin nf sinriinn at 7004 rntad Printed 2/23/961109:57 AM Page 1 of 2

1) On page 5 of Calcul.ation #143E, the transposed valla for ampacity of #10 cable is identified es 41 instead of 40. This discrepancy has no impact on the calculation's output.

2) Table-2 on page 6 of calculation #143E identifies cable sizes for L-tray. According to Calculation #67E, #4 and #2 cables can be routed in L tray. If these cables can be validly routed in L-tray, they should be addressed in Table-2.

3) Page 12 of Calculation Change Notice #3 of Calculation

1. 195E, identifies a derating factor of .85 for 3 conduits spaced horizontally. A redew of the appropriate reference identifies this derating factor as .91. A more conservative value was used; therefore, this discrepancy does not adversely impact the calculation's output.

These discrepancies are not considered to adversely impact the output of the calculations. Therefore, the plant's licensing and desi0n basis is still met, and this discrepency report is rated a Significance Level 4.

Ducripuon: FSAR Section 6.1.1.1 states that mechanical proporties of the materials used in the engineered safety features (ESF) are in accordance with ASME Boiler and Pressure Vessel Code, Section 11.

The FSAR statement in Section 6.1.1.1 clearly apphes the requirement for materials to all safety-related piping and components. However, application of this requirement to pressure boundary materials appears more appropriate.

Since the FSAR Section 6.1.1.1 does not specify that the mechanical properties of pressure boundary materials, only, are in accordance with ASME Section ll, all safety related quench spray system materials are evaluated against the mechanical properties in ASME Section 11.

All materials in safety related components are designated "SA" or "SB' from ASME Section 11, Parts A and B except for the following:

Therefore, components made from materials complying with these specifcations are considered acceptable.

However, specifications B-438, SA-276 and SA-296 are not listed in ASME Section 11. Therefore, components constructed from materials designed to specifications B-438, SA 276, SA-296 A 276, and A 296 do not have mechanical properties in accordance with ASME Section 11.

Date Published: 1/1oS8 Descrepency: First Level Undervoltage Relay Setting (Calculation NL-040)

Descriptioe . Calculation NL-040 determines the sett!ng of the first level undervoltage relcys. These relays detect the complete loss of

' power to a bus. (Calculation NL-042 determines the setting of the second level undervoltage relays that respond to sustained low bus voltage. See DR-MP3-0542.)

The first level undervoltage relays operate with a 1.8 second time delay, while the bus overcurrent relays take about 1,7 seconds to clear a line to line fault. The margin of 0.1 second is short, and may result in a loss of coordinatioit between the two relays. A margin of 0.3 second is allowed for coordinating overcurrent relays at Millstone 3, which provides margin to ensure that the relays operate as intended. A longer time delay setting of relay 62V would provide greater assurance that the ma,,1 circuit breaker has had a chance to clear the bus fault and lock out the feed from the RSST, thus preventing exposing the RSST source to a fault. Therefore, a coordination margin of 0.3 second is appropriate here, also.

The calculation cites information from General Electric on the characteristics of Typo NGV undervoltage relays. However, this information is contained in an unverified telephone memorandum, According to the telephone memorandum, General Electric was to follow up the telephone conver' . tion with a letter. The letter is not included in the calculation.

f The casu, ion includes a description of the closing of the feed frot.. .. e RSST on undervoltage. No reference for this is given.

Both Calculation NL-040 and Calculation 420CB set time delay relay f'P. While the proposed setting is the same in both calculo..ons, any given relay should be set in only one calculation to ensure consistancy.

Date Published: 12/B/97 D6screpency: Discrepancies in Cable Calculations for Heater Feeds

Description:

The review of Calculation #69E

• Maximum Cable Lengths for Heater Feeders to Heaters with 'Aotor Driven Fans' and Calculation #127E

• Sizing Cables for Heater Branch Circuits

1. HVR*FLT 1 A,1B,2A,28,3A, and 3B' identified miscellaneous discrepancies in the calculations. The specific items are as follows:

1) Page 2 af Calculation #69E identifies IPCEA P54-440, Table 27 as a design input for K-Tray ampacities. Table 11 should also be listed.

2) The actual diameters used in Table A on page 2 of Calculation #69E correspond to the maximum guaranteed values identified in the cable specification. This is non-conservative with respect to using the minimum guaranteed values identified in the cable specification.

3) Assumption #2 of Calculation #127E states that the cables are sized based on ampacities and that voltage drcp is not a goveming criteria. Because of the cable length discrepancies identified in item #7 and the fact that some of these lengths do not meet the criteria for maximum cable lengths established in Calculation #69E, the validity of the assumption is not readily apparent without more in depth analysis. For this reason this attribute should be addressed in the calculation by more than just an assumption, A preliminary review indicates that voltage drop may not be a concern due to the relatively high degraded voltage values at the associated buses.

4) Assumption #3 of Calculation #127E assumes no more than two conduits running in parallel. A review of the conduit plan drawings (e.g. Drawings EE-48A and B) has concluded that at the power feed panels for heaters 1 A,2A, and 28 there are cases of three power condults in parallel.

5) Assumption #' of Calculation #127E assumes no additional power cables will be installed adjacent to the analyzed conduits.

A review of the electrical Installation drawings has not identified any note or direction ensuring this limitation is maintained.

6) Calculation #127E states that the heater power feeds being analyzed are run in 4 inch condult. A review of the cable raceway oata report has identified that some of the conduit runs are 3 inch condult. Also, the calculation identifies all the heater feeds as #4 AWG. A review of the cable schedule data report has identified some of the feeds as #2 AWG. These differences p g in ceb! Ond-conduesize v"! affect the pertiene of the p g3

DR No, DR-MP3 0689 N:rthe:st Utilities ICAVP Millstone unit 3 Discrepancy Report calculation which analyze conduit fill.

7) Calculation #127E lists cable lengths for the different nicater power feeds analyzed in the calculation. These lengths are sigriif!cantly less than those lengths listed in the cable schedule data report.

8) A review of Calculation #127E did not identify any considerations for the portions of the power fceds which are run in cable tray.

These discrepancies are not considered to adversely impact the output of the calculations. There iire conservatisms in the calculations ensuring adequate sizing of heater power feeds. For this reason this discrepancy is rated a Significance Level 4.

1)Section I.A.2 of the calculation states that for loads greater than 7.5 A a cable is assigned a *K' service. The source for this design input (i.e., installation or design document) could not be identified. CCN #1 page 1, paragraph 3 implies that the subject calculation is the design basis for this input. This same CCN (page 2) identifies instances of 'C' cables exceeding, 7.5 A.

2) Section 8 of the calculation identifies the equation for the correction factor due to number of cables, but omits the ratio of cable diameters from the equation. This omission is editorial in nature since the correct equation was used in the body of the calculation.

3) CCN #1 uses a methodology which uses 50% of calculated cable area since the loading of cables in the trays is assumed to be 50% of the allowed load. A basis for this methodology could not be identified. Also, an adjustment in direct proportion to the reduced loading is not conservative due to non-uniform heat intensity in the cable tray.

These discrepancies are not considered to adversely impact the 2 output of the calculation. There still appears to be enough conservatism in the sizing of 'C' cables to ensure adequate ampacity. For this reason this discrepancy is rated a Significance Level 4.

Descrylon: The ICAVP reviewed FSAR Sections related to natural circulation subsequent to reactor trip and reactor coolant pump coastdown. The specific sections reviewed were:

1) Loss of Nonemerger.:y AC Power to the Etation Auxillaries (FSAR $15.2.6),

2) Loss of Normal Feedwater Flow (FSAR $15.2.7),

3) Feedwater System Pipe Break (FSAR $15.2.8), and

4) Complete Lo:s of Forced Reactor Coolant Flow (FSAR

$15.3.2.2).

In these sections Table 15.2 2 is cited as the justification for natural circulation flow that is s afficient to provide adequate core decay heat removal following a reactor trip and reactor coolant pump coastdown and therefore, seceptable rapability to respond to the accidents.

IRF 01099 which responded to RFl 689, provided a Westinghouse letter (NEU 97 305E) which states *The values presmnted in Table 15.2 2 are estimates of the amount of natural circulation flow that is expected under these conditions, however, they are not used in the non-LOCA safety analysis in any way.'

Specific sections of the FSAR where credit is taken for natural circulation for non LOCA analysis are discussed below; a) FSAR $15.2.6.3 for accident 1) above states ' Conclusions .

Analysis of the natural circul,: lion capability of the RCS has demon.=trated that sufficient heat removal capability exists following reactor coolant pump coastdown to prevent fuel or clad dama,e.'

b) FSAR $15.2.7.2 for accident 2) above states ' Method of Analysis. Assumptions mede in the analysis are as follows. 3. ,

For the case with a loss of off. site power, a heat transfer coefficient in the steam generator associated with RCS natural circulation.'

c) FSAR $15.2.8.2 for accident 3) above states

• Method of Analysis . The code describes the plant thermal kir stics, RCS inriuding naturel circulation, . .* Also this sectiore states

'Followine '- trip of the reactor coolant pumps, there N a flow coastaenn until flow in the loops reaches the natural circulation value.'

Dete: 2/20/98 RESOLUTION: Disposition: NU has concluded that the issue reported in Discrepancy Report D,' MP3-0718 does not represent a discrepant condition.

Westinghouse Letter NEU 97 30$E, dated Novembnr 21,1997, responded to Sergent and Lundy questions regarding the adequacy of FSAR Table 15.2 2 for use in the analysis of the feedline break event by desutbing the purpose of FSAR Table 15.2 2. This letter states the values presented in FSAR Table 15.2 2 are not utilized in any non LOCA safety analysis.

Westinghouse, as the Fuel Vendor for Millstr.,ne Unit 3, has reviewed the request for NU to compare the Millstone 3 Fuel Reload Analysis of record with FSAR Sections 15.2.6,15.2.7, 15.2.8 and 15.3.2 to determine if the values in FSAR Table 15.2

? are used. Westinghouse responded to this request in Letter NEU 98 510, dated February 6,1998 and again stated the data is not used in any of the non LOCA transient analyses.

Westinghouse Indicates the informction in the subject table is used to validate the analytical model used to perform this portion of t5e Chapter 15 safety analysis. This letter states that by showing that the actual natural circulation flow determined from the startup tests met or exceeded the values in Table 15.2 2 at inillal startup, the validity of the transient analysis natural circulatso model is confirmed. The letter further states that the emount of natural circulation flow for these events that assume a loss of forced reactor coolant flow is calculated by the computer code (LOFTRAN) based on transient conditions.

Westinghouse Letter NEU-98 510 indicates that changes were made to FSAR Section 15.2.6, via FSAR change 97 MP3-42, in order to clarify the application of this table. Additionally, Westinghouse provided proposed wording that can be incorporated in the FSAR if NU determines that the discussion on natural circulation flow within the FSAR requires additional clarification.

Conclusion:

NU has concluded that the issue repurted in Discrepancy Report DR MP3 0718 does not represent a discrepant condition. Westin0 house Letter NEU 98 510, dated February 6th,1998, confirmed again that the data contain0d in FSAR Table 15.2 2 is not used in any of the non LOCA transient analyses but rather was L'tllized to validate the analytical model used to perform this portion of the Chapter 15 safety analysis.

The letter states that the amount of natural circulation flow for these events that assume a loss of forced reactor coolant flow is calculeted by the computer code (LOFTRAN) based on transient conditions.

Westinghouse has provided additional clarification, via this letter, that can be added to the FSAR to ensure the purpose of Table 15.2 2 is not misunderstood by those not familiar with non-LOCA tr6nsient analysis methodology, CR M3 98 0687 was written on 2 6-98 as an enhancement CH to request the recommended clarifications be evaluated for incorporation into the FSAR if NU review determines they are necess'.ry.

Date: 2/20/98 RESOLUTION: Disposition:

NU has concluded tisat issues # 1,2 and 3 in Discrepancy Report, DR-MP3-0122, have identified conditions not previously discovered oy NU which requires correction.

Issue # 1) discusses a confilet between Figure SA on EE 9JF and a number of RSS, QSS & SWP motor operated valve ESKs for the intemal wiring of the 42-0 & 42-C seal in contacts to TB1.

The present configuratiori in this figure shows the 42-0 contact wired to TB1-4 & SA and the 42 C contact wired to TB1-2 & 3A.

Atter a review of each elementary with their corresponding intemal and extemal MCC wiring drawings, it has been determined that Figure SA on EE 9JF is in error for the referenced schematics. This figure and it's assochted table should be revised for the referenced schematics to show the 42-O contact wired to TB15 & SA in lieu of TB1-4 & SA and the 42 -

C contact wired to TB13 & 3A in lieu of TB1-2 & 3A. This is drawing change caly, and will bring all the documents into agreement with this revision.

Issue # 2) A review was performed of ESK-6AAX, EE 9GB &

Figure SA on EE 9JF for the location of terminal point 2 in the closed circuit of 3SWP*MOV102D. Both intemal and extemal wiring drawings depict the locaticn of terminal point TB1-2 to be between the valve's limit / torque switch and the 57-58 contact of 52S-3SWP*P1D.

This agrees with the SWEC termination tickets "or conductor SC2 in cable's 3SWPDPC045 and 3SWPDPCOC as well.

Therefore, ESK-6AAX needs to be revised to show terminal point 2 in the same location as it's corresponding intemal and extemal ning drawings. This is a drawing change only, no field work required.

issue # 3) The referenced SWP & RSS motor operated valve Printed 2/23/9811:46:11 AM Page 2of 4

DR No. D8t-MP3 0122 I Northeact Utilities ICAVP i Miiistone unit 3 Discrepancy Report schematics were verified against Figure SE on EE 9JM to validate the discrepancy. The Figure depicts an unneeded jumper between TB12 & 7 and tiimination of a required jumper between TB1-4 & 12, by means of a deviation symbol (i.e. a darkened triangle). The darkened triangle means that an internal wire needs to be added to the Figare and is correlated with the applicable starter by the addition of this symbol to the deviation column of the corresponding table. Since the darkened triangle is not in deviation column for the referenceo schematics, the impression given is that the needed jumper appears not to be installed and unneeded jumper appears to be insialled in these starters. However, it has been determined that this symbol is misplaced in the Figure and should be moved to be to the left of the jumper between TB12 & 7. This will eliminate the unneeded jumper batween TB12 & 7 and insert the lequired jumper between '!31-4 & 12. This change has already been documented by DCN DM3-00-079197 which was approved on 7/25/97. Since this is after the 27 of May, credit could not be taken for pre-discovery. There is no additional change needed by this issue.

Conditior Report (CR) M197 3711 was written to provide the necessary corrective actions to resolve these issues. Approved Correc'ivo Action Plan (CAP) (attached) and DCN DM3-00-1765-97 were issued to correct the design drawing discrepancies. No work is required in the field.

NU also has concluded that issues # 4 and 5 in Disccepancy Report, DR MP3-0122, do not repregnt discrepant conditions.

t Issue # 4) Both schematics ESK-6AAU rev.13 and 6AAW rev.15 were reviewed against wiring drawings 2424.100-245-689 rev.E, 690 rev.E,691 rev.F & EE 3BA rev.4 for the wiring at polms 25-26-27 on the transfer switches for both motor operated valves and a discrepant condition could not be found on any of these drawings. There are no changes required by this issue.

Issue # 5) This issue implies there is a discrepant condition between Figure SD on EE 9JM rev.5,9FX rev.12,3BA rev.4 &

ESK 6AAU rev.13 for the wiring from fuse FU-F2A through TB1-2 in the MCC to TBB-48 in the FTSP. However , a discrepancy could not be Wnd during this verification process it appears Figure SD on EE 9JM was misinterpreted, because ustr.g the rieviation symbol (l. e, darkened circle) all the documents are in agreement.

Date Published: if22/97 Discrepancy: Areas maintainod at a negative pressure by SLCRS and ABVS Descript6on: During review of the Supplementary Leak Collection and Release System (ELCRS) and the Auxiliary Building Ventilation System (ABVS) discrepancies regarding 1) which buildings and areas are multf air.ed at a negative pressure dring a LOCA and

2) which systems are required to maintain the negative pressure were identified.

FSAR Section 1.1.10 states that following a postulated accident, particulate and gaseous railloactive material is ducted from the containment enclosure and de buildings contiguous to the containment structure to the suppiementary leak collection and re! ease system (SLCRS), where it is filtered and discharged to the atmosphere thruogh an c!evated stack rather than through a ground-level vent.

FSAR Section 3.1.2A1 states that the supplementary leak collection and release system (SLCRS) collects radioactive leakage fiom the containment to the containment enclosure and contiguous areas following a LOCA or releasc of radioactivity due to a fuel handling accident.

FSAR Section 6.2.3 states that the seconda9/ containment is comprised of the contal- 9nt enclosure building, engineered safety features building (partial), auxiliary building, main steam building (partial), and hydrogen recombiner building (partial). The secondary containment is kept under a negative pressure relative to atmoshperic pressure. The negative pressure is maintained with the SLCRS operating together with the charging pump, reactor plant component cooling water pump and heat exchanger area ventilation system and auxillary building filtration portions of the auxiliary building ventilation system (ABVS). The SLCRS operating together with the charging pump, reactor plant component cooling water pump and heat exchanger area ventih, tion system and auxiliary building filtrction portions of the auxiliary building ventilation system (ABVS) also maintains all contiguous buildings (main steam valve building, engineered safety features building (pertially), hydrogen recombiner oul ding (partially), and auxiliary building) under a negative presSJre following a DBA by exhausting air from these areas.

FSAR Section 6.2.3.1 states that the SLCRS is designed to maintain a regative pressure in areas contiguous to the containment.

FSAR Section 6.5.1 states that the SLCRS system operated in conjunction with the charging pump, component cooling pump, Ond h00t 0xch0 ger exh0c0' ventilation cycten, ncluding ,4 p g

FSAR Section 6.5.3.2 states that the secorv'sry containment at Millstone 3 consists of a containment enclosure structura and the contiguous buildings.

P&lD EM-148E-12 and ductwork drawings EB-72A-8 and EB-728-6 shows that the SLCRS does not directly er.haust air from the hydrogen recombinor building as blankoff plates have been installed on the exhaust openings.

P&lD EM 148A-24 does not show the ABVS exhausting air from the main steam valve building.

P&lD EM-148E 12 does not show the SLCR exhausting air from the main steam valve building. P&lD EM 1528-10 shows 1,350 cfm transfer air to the SLCRS in the auxiliary building thru containment enclosure via MSV/ Cont shake space.

DR MP3-0509 identifies that P&lDs EM-148E, EM-148A, and EM 152B do not provide the general area exhaust flow paths required to maintain the Secondary Containment under a negative pressure following a LOCA. The format and content of the MP3 P&lDs are established in procedure EDI 30255,'MP3 Piping and Instrumentation Diagrams Detailed Instructions for Format and Content." 90! 30255 does not require MP3 P&lDs to reflect the actual bunaing arrangement. The P&lDs provide the systems configuration required to maintain the Secondary Containment under a negative pressure following a LOCA. The PGlDs are not required to provide general area exhaust flow rates, therefore, changes to P&lDs EM-148E, EM-148A, EM1528 are not required.

The Secondary Containment is comprised of the containment enclosure building, the auxiliary build'ng, and sections of the engineered safety features building, the main steam valve building, and the hydrogen recombiner building.

The summary table shows the exhaust flow rate for the containment enclosure building as 4950 cim, the hydrogen recombiner building as 130 cfm and the main steam valve building as 1350 cfm. P&lD EM-148E indicates the total exhaust fiow from these areas through the 36" X 18" screened opening as 6430 cfm As an enhancement, FSARCR 97 MP3-569 was initiated, on 7/28/97 to revloe FSAR Section 6.2.3 to clarify the Secondary Containment Boundary. FSARCR 97 MP3-369 was initiated as a result of the CMP FSAR annotation process. Clarification of FSAR Sections 1.2.10,3.1.2.41, and 6.5 is not required with respect to the Secondary Containment Boundary.

As an enhancement, CR M3-07-4557 was initiated to clarify the air flow rates on all of the MP3 P&lDs. CR M3-97-4557 correct:c action requires a review of all air flows and notes on HVAC P& ids, related Technical Specifications, and FSAR Sections. Based on the evaluation results, the P&lDs will be revised to include clarifying notes or remove sir flow information and revise EDI 30225,if required.

Significance Level criteria do not apply here as this is not a discrepant conditlua. g

The unducted airflow paths from the main steam valve building and hydrogen recombiner bulling should be shown on the P&lDs but do not necessarily need to show the specific airflow quantitles.

P&lD EM-148E 12 indicates an exhaust flow of 6,430 cfm at the 36' x 18' screened oper'ing in the containment enclosure, it does not identify that a portion of the air exhausted is drawn into the containment enclosure from the main steam valve building and hydrogen recombiner building as indicated in NU's response.

Disposition:

NU has concluded that the issue reported in Discrepancy Report, DR-MP3-0506, does not represent a discrepant condition. Since 30SS*MOV20D does not exist, it is assumed that the valve in question is 3RSS*MOV20D. A walkdown determined that valve 3RSS*MOV20D was located near ESF Building Steel. A review of the Accelerations end Displacements Table B-2 (attacheQ for the Containment Structure and Table B-11 (attached) for the Engineered Safety Features Building concluded that the sum of the North-South displacements for SSE at the nearest elevation of the valve is 0.134'. Due to the configuration of the piping the valve will move away from the ESF Building Steel as the system grows thermally or during a DBA so these displacements are not of concem, accordingly no interaction condition exists.

Significance Level criteria do not apply here as this is not a discrepant condition.

Conclusion:

NU has concluded that the issue reported in Discrepancy Report, DR-MP3-0556, does not represent a discrepant condition. A review of the Accelerations and Displacements Table B-2 (attacheu) for the Containment Structure and Table B-11 (attached) for the Engineered Safety Features Building concluded that the sum of the North-South displacements for SSE at the nearest elovation of the valve is 0.134".

The disposition that, since the valve will thermally move away from the Interference during system operation or during a Design Basis Accident, no interaction condition exists, is not acceptable. During an SSE event, if the system is not operating, the valve will not thermally move away from the Interference. For the RSS system, this is the more credible DBA case.

The subject valve operator for 3RSS*MOV20D is shown on Piping Location isometric Cl-RSS-7 Sheet 3, and the associated piping is analyzed in pipe stress analysis calet,lation NP(B)-X7919 Rev.2.

According to the commodity c!carance evaluation performed in the stress analysis calculation, ' locations with a clearance less than 1" are identified on the piping location isometrics'. However, PLI Cl-RSS 7 Sh. 3 does not show the 3/4" clearance identified in this DR.

Also, according to the commodity clearance eveluation, locations where piping displacements exceeo 1* are evaluated in Attachment F of the stress analysis calculation. The valve o,corator is modeled in the stress analysis as !!P618. According to Attachment F, SRSS of the total movement at NP618 exceeds 1". Yet, the 3/4" clearance between the valve operator and the ESF building steel has not been identified or evaluated.

Description:

Technical Sper.lfication 4.7 4.a.2 requires that *Esch Service Water System pump starts automatically on en SIS test signal."

It could not be determined that the existing surveillance tests asst're that this requirement is met. SP 3646A.15, SP 3646A.17.

OPS Forms 3646A.151 and 3646A.17-1 are used in conjunction to verify that both serWee water pumps in Train A are started eutomatically with an SIS signal, ideally OPS Form 3646A.15-1 tests pump A and OPS Form 3646A.17-1 tests pump C.

At the bottom of OPS Form 5646.t151, page 2, note 2 states that *3SWP*P1 A should be the lead pump. If 3SWP*P1 A is not availab'e, select 3SWP*PtC as the lead pump and ensure 3SWP*P1 A is the lead for t P3646A.17 or is documented on 3646A17 2 as requiring a .etest when it is available." It is not apparent how this requirement is followed through since there is no requirement on OPS Form 3646A171 to test the opposite pump. The only notation is "If possible, the SW pump not tested in lead during SP3646A.15 should be lead pump." This doesn't reflect a requirement to verify and document. Neither SP3646A.15 or SP3646A.17 list the completion of the other hs a prerequisite so the order of perfo mance isn't required to assure that equipment isn't missed.

OPS Form 3646A.151 (16-i,171,16-1) footnotes suggest that a specift pump be made the lead pump for the test but the form does not provide a place to document that this requirement is y

met. f-ootnote 2 on OPS Form 3646.171 states that "If possible the SW pump not tested in lead during SP3646A.15 should be lead pump." The same footnote on the corresponding procedure for B train states "The SW pump not tested in lead during SP3046.16 must be Isad pump." These two requimments are not equivalent.

A review of the test resuks of SP 3646A.15,16,17 and 18 and their associated OPS Forms 3646A.151,16-1,171 and 18-1 for the pt.rlod 5/96 through 7/96 reveal the following:

No requirement exists that all equipment associated with a specific test is to be available prior to performing the test.

Testing prerequisites are not specific regarding system alignment. The SPs are mute on prerequisites for SWP status and leaves the decision on which pump should be running to the test director based on footnotes on the OPS Fonas.

Dele: 2/17/98 st.conenents: The CR which was Generated does not contain a corrective action plan. Attematively, the DR Review Screen by the expert panel and BPM dots not contain any statement that the initial technical issue which was documented in ACR M3-96-0721 has indeed S

been resolved which would support the Review Screen conclusion that the issue is only " Administrative'.

Since we have no indication that the technical issue was ever addressed, the response is not acceptable, w

Diecrnancy: Modification M3 9709410CFR50.59 Safety Evaluation Screening Checklist Descripoon: Modification M3 97094, 'RSS Loop Seal Detection," establishes a new serveillance requirement for tha RSS system. The new monthly surveillance requires verificatirAL that the thermal expansion legs of lines 3-RSS-006 40 52 54, and 55 are full of water. This surveillance assures that the RSS system will not deliver trapped air bubbles to the HHSI ECCS pumps upon completion of manual ECCS suction switchover during a postulated LOCA.

This surveillance requires that a change be made to TS surveillance requirement 4.5.2.b.1 as outlined in DR-MP31031.

This constitutes a change to a procedure described in the SAR.

However, the 10CFR50.59 safety evaluation screening checklist for M3 97094 was answered, "no" to the question, "Does the activity make changes to procedures as described in the SAR?"

The technical issue of what surveillance procedu;e changes were omitted from the mod is already addressed DR MP3-1031. This DR addresses only the issue of the error in the 10CFR50.59 screening checklist.

If TS Surveillance 4.5.2.b.1 did not nced to be changed as described in DR MP3-1031, the 10CFR50.59 screening checklist for modification M3 97094 would have been completed correctly.
