QSS swgr pump breakers.
DeecrWlon: Discrepancies between the pump breaker schematic and wiring drawings are noted below:
y
- 1) In the trip circuit of the Service Water Pump (3SWP*P1B) breaker, the schenutic diagram (ESK 5CK Rev.16) indicates a connection between terminal point BB 12 and point 67 on contact 67 68 of handswitch 52S 3SWP*P1B. T'1e corresponding wiring diagram 25212-39010 sht. 498 Rev. F, at terminal point BB 12, does not indicate this connection.
- 2) Schematic diagr%m (ESK SCN Rev.13) for 3RSS*P1 A indicates an electrical connection between terminal point AA 3 and handswitch 43-3RSS*P1 A (contact 5), in the closing circuit of the breaker. The corresponding wiring diagram (25212 39010 sht. 449 Rev. F) does not indicate a connection between these 4
two points.
- 3) The closing circuit of the RSS pump breaker (3RSS*PI A -
schematic diagram ESK 5CN Rev.13) Indicates a series
- permissive
- using handswitch 43-3RSS*P1 A (contset 10) and auxiliary relay 1X-3RSS*P1 A (contact 17). This portion of the schematic diagram doec not match the corresponding wiring diagram 25212 39010 sht. 449 Rev. F. As an example, this wiring diagram Indicates that both sides of contact 10 (43 3RSS*P1 A) are both connected to point 7 of auxiliary relay 1X-3RSS*Pi A.
- 4) Schematic diagram (ESK-5DH Rev.11) C 3S*P3B indicates a connection between handswitch (n.,QSS*P38) contact point 3C and handswitch (43-3QSS*P38) contact 13C.
The switchgear intemal wiring diagram 39010.sht. 484 Rev. E does not Indicate a connection between these two points. In addition, schematic diagram ESK-5DH Rev.11 Indicates a seal-in contact (12) on the reset coil of relay 86E. The switchgear inieman wiring diagram 39010 sht. 484 does not indicate a seal-in contact.
- 5) Schematic disgram ESK-6ALG Rev. 7 (3SWP*P3A &.
3SWP'P38) indicates the use of a General Electric CR120BL relay, which contains an " operate & reset
- coil. The corresponding wiring diagrams refers to wiring diagram EE-9JS Rev. 2, figure 11H, for the wiring of these relays (3 3SWP*P3A
- & 3-3SWP*P38). Figure 11H does not contain these types of relays.

Date PutWehed: 1/2596 D6ecropency: Cable capacitive effects are not addressed (Calculation 02 LOE.
078E3)
D*ecription: This calculation was prepared to establish the maximum permitted cable lengths for use in iaotor control circuits. The calculation determines the maximum permitted cable lengths based only upon voltage drop.
Small control relays should also be reviewed because of their small holding current requirements to determine whether the capacfilve current contained in lengthy, multi-conductor cables may be a problem by preventing relay dropout after the circuit is interruptad. Mutual capacitance should be addressed in the calculation to determine the maximum allowed cable lengths.
Per CCN 2 of the calculation, the maximum allowable cable length for the Size 1 starterwhich has GE CR120B relays rated at 15 Holding VA is 5814 feet fur a #10 AWG cable.
For this application, S&L's standard would allow a maximum cable length (cable length being equal to 1/2 of the circuit length) of approximately 2400 feet (41% of the length allowed by NU).

D6ecrepency: Service water Stralner timers not in calibration program
==
Description:==
Plant Design Change Request (PDCR) # MP3-92-013 replaced four time delay relays in the Service Water Pump Strainers. The PDCR was identified as a AQ, Cat. I activity and that the new time delay relays were required to be qualified as class 1E devices. Further, the PDCR documented the requirement to up date procedure PT 31459A, MP3 Timing Device Calibration s
Program. Revision 2 CH 2 of this procedure which has an effective date of October 1,1997 does not include the replaced time delay relays.
NU's Quality Assurance Program (NUQAP) states that ' Periodic c9libration and adjustment of measuring rN test equipment is performed and controlled to assure accuracy is maintained within limits necesury to verify and control to assure accuracy is maintained within limits necessary to verify that design and s
operating condition requirements have been met. The ope ating requirements for these relays is identified in the PDCR as providing a safe and reliable means of allowing the system to remain in its automatic mode to provide automatic gross filtering of the service water system cooling water.
No documentation was provided that would verify the service water pump strainer timers were included in the Mill *one Unit 3 timini device calibration program or weie calibrated on a scheduled frequency.

Rev. 9 require the correct labeling cf components and raceways. The following labeling anomalies were noted with regard to these requirements
- 1. %" conduit listed on drawing as 3CC834PB3 has no tag in field and is not listed on raceway schedule. Conduit routes to non-safety related box 3JB2522, yet also routes to box near equipment that also contains the "P" safety-related condult.
(Reference drawings FSK-AB-8005, Rev. 2 and FSK-AB-8113, Rev. 2)
- 2. Conduit is listed as 3CK1060G1on drawing FSK-MA-1017, Rev. 2A. TSO2 and field walkdown determine correct ID is 3CX1060G1.
- 3. The field !ag on this support is 1259 which is a duplication of another support nearby. (Reference drawing FSK MA-1039, Rev. 3)
- 4. J-Box is identified on support drawbg FSK-AB-1291 Rev.1 A as 3CCP*JB19A. Tag in field is 3CCP'JB197A.
5 Drawing FSK-AB-4484, Rev. 3 identifies supponed J-Box as 3JB-2624. Field tag is 3JB*2624.
- 6. Conduits 3CX9260G and 3CX9260G7 are not identified in field.
- 7. Junction box 3HVP*JB268 is not identified in the field.
- 8. The wire way 3CES-RK12 8 is not tagged in the field.
Conduits to this raceway from Instruments 3HVR-PDIS918,938, and 94 B,157A,157B do not shcw the wireway as a from/'o for the conduits; but shows the from/to as "end".
- 9. Conduit 3CC11500 did not have an identification tag installed.
10.-Junction boxes 3HVR*JB1-1 A and 3HVR*JB1-2A have erroneous instrument information listed on the box in the field.
The boxes are also mis-identified on drawing EB-45G Rev. 9.
Field and drawing indicate boxes are for 3HVR*TS175A-1/ A-2 and 3HVR*TS175A 3/ A.4 respectively. The correct designations for these boxes are 3HVR*TS175A 1 and A-2 respectively. Similar situation exists for instruments 3HVR*175B-1 and B-2.

Date Published: 1.25so Descrepancy: Conduit Supports not in accordance with design documents Ducripuora Standard Selsmic Conduit Support criteria are included in the 12179-BE 52 Series drawings. These drawings include allowable spans (i.e., the distance to the next support) for
'onduits. Contrary to the requirements of these standards, the fo. owing anomalies were observed during system walkdowns.
l
- 1. Conduit 3CX9260C has a span of 8 ft, to adjacent supports from that shown on Conduit Support Log 121790-FSK DG042, Rev. 4. This is greater than the allowed span for any conduit in any location.
- 2. Conduits 3CX95000 (identified as OC on CSL) and 3CX9500N4 are attached to support CB 1541 as shown on Conduit Support Log 12179-FSK-1541. The span tu adjacent supports for these conduits exceed the allowable as specific on drawing BE 52AN, Rev 5.
- 3. Conduit 3CX449NX3 is listed on Conduit Support log 12179-FSK DG-129, Rev. 4A, as attached to the support. This conduit is not attached and as a result its span of greater than 7 feet 4 inches exceeds the allowable.
- 4. Conduit Support Log 12179-FSK CB 555, Rev. 8, in Section 1 shows all conduits attached to the top of the horizontal members. This is not accarate; all conduits attached to de B member are below as is 2 of the 4 on the C member.
- 5. Drawing 12179-BE 52AS, Rev. 4, Note 65 provides guidance on the use of flexible conduit mid-run and requirements for such applications. The maximum allowable length of flex is 4 feet, maximum distance to the first support is 2 feet and the maximum distance to the next support is 3 feet ( the " rigid back span"). With respect to these requirements, the following field condMons were noted: Conduit 3CX9260G5 has a rigid back span of 4 feet -10 inches, Conduit 3CX9260A has a rigid back span of 4 feet-5 inches.
- 6. Conduit support log 12179-FSK-DG490, Rev. 4 shows two conduits for the support in section 1. only one conduit is listed as attached and field observations revealed only one conduit attached.

Jxy* Dud Support Calcolation Olscrepancy Dmertpenon: We have reviewed Pipe Support Calculation No.12179 NP(T).
Z545J 1235, Rev.2.
Based on this review we noted the following discrepancies.
- 1. On page#12, Angle 4x4x3/4 is analyzed and due to interference, Angle 4x3x1/2 is used in the field.
This is noted in the calculatioli and accep4d by engineering judgernent. Angle 4x3x1/2 has lower sectional properties and it is not structurally adequate as shown below.
Ratio of A,eas= 5.44/3.25=1.67 sq. In.
Therefore, actual axial stress =fa=11704x1.67=19590 psi KUr (min)=1.0x64/.639=100 Therefore, allowable axial stress =Fa=12.98 ksl < fa=19.59 ksi (NO GOOD)
- 2. Angle sections are not checked for r.ombined axial and bending stresses and also the AISC CODE check is not performed in STRUDL RUN.
- 3. On page#13, for Angle 6x4x1/2 axial stress ratio fa/Fa=.Pi>,15 and it is quahfied by engineering judgment.This is unacceptable methodology.

Date Putd6ehed: 1/259e Descrepency: No program has been established to measure DG cylinder firing pressures and evaluate results Deecripuon: The letter from Northeast Utllities to the NRC dated June 14, 1995 (B15245) statec that '...we have decided to implement a supplemental Inspection in order to better evaluate engine performance. Cunently only rock settings and temperatures are monitored during diesel surveillance runs. Maintenance on a six-month basis will measure cylinder firing pressure and evaluate the results. This will allow an evalustion of the engine timing (retard or advance) and fuel mixture (too rich or too lean).*
RFI 0824 was submitted to obtain the procedure and data sheet that is used to perform the task as described in letter 815245.
The RFI provided a copy of Maint Form 3720CD 1, Rev 3 and referred the reviewer to MP 3720CD, Rev 4 even though OSCAR identifies a Rev 6. The RFI also requested copies of the three most recent uses of Maint. Form 3720CD 1 which had been provided earlier in response to RFI 0715.
Contrary to the above comm!! ment, the reviewer was not able to confirm the following:
- 1. A program has been established to perform a twice year 1y evaluation of the diesel cylinder firing pressures.
- 2. That when data is collected on Maint. Form 3720CD 1 that there is a documented process to calculate the hi0h/ low differential exhaust temperature and firing prer ',ure.
- 3. That any documented evaluation is performed to determine proper engine timing or fuel mixture.
- 4. A process that describes follow-up actions that the evaluation might require.
The work orders associated with " copies of the three most recent ucas of Maint. Form 3720CD-1' provided were dated 9/6/93, 2/1/94 and 5/16/95, it therefore appears that this surveillance has not been performed since 5/16/95 which includes all of 1996 and 1997.
The RFI also requested copies of evaluations performed as a result of the testing program. The site responded that "there have been no evaluations performed because cylinder pressures have not exceeded the limits and rework was not performed."
The subject letter appears te commit the station to a twice yeariy cylinder firing pressure surveillance test of the diesel which includes a subsequent evaluation for engine timing and fuel mixture, it cannot be determined that this program is in place and therefore this is a discrepancy.

t A review of the documents provided by RF1-0824 did not confirm that the retest requirements were completed for the following reasons:
- 1. No docum'rts were provided that contained pressure and flow readin0s for the heat exchangers "just put back on line* that could be used to established the "before" or " baseline" readings.
l
- 2. Only one set of "after" readings were provided for heat exchanger SCCP*E1 A. Thors was no "after" data provided for heat exchan0ers SCCPM1B or 3CCP*E10.
3.- No vibration data was provide.d.

As part of that review the following discrepancies were noted.
- 1) The E 3 procedure cites a 46-minute time for completion of the adions necessary to complete plant cooldown to cease the tube rupture break flow and terminate the release. it is cited in the purpose of the procedure and Indicated as consistent with the FSAR. The ICAVP team notes that the FSAR cites a 30-minute time period for this action and it,s associated offsite release assessment uses the 30-minute time for the rolesse duration.
- 2) The FSAR Indicates that the operator controls the ruptured steam generator at the steam generator relief valve setting. The E 3 procedure diiects the operator to control the ruptured steam generator at a pressure of 60 psi below the relief valve setting.
This inconsistency could cause an under prediction of the release from the RCS to the steam generator.
NU has identified in UlR 1061 that the affected safety analyses for the steam generator tube rupture need to be updated.
However, the assumptions and EOP inconsistencies identified above should be reviewed and factored into the safety analyses and, if determined to be appmpriate, coordinated with EOP revisions.

EOP 35 E 3,' Steam Generator Tube Rupture", Rev.13, Effedive 10/3/95 MP3 Reg. Guide 1.97, Rev. 2 Basis Document MP3 FSAR Chapter 7.5 a
The ICAVP has reviewed the reference EOP as part of the verification of plant charaderistics important to ensure that safety analysis assumptions are appropriately implemented and maintained in accordance with the MP3 FSAR Chapter 15 accident analysis. As pa t of this verification the ICAVP reviewed the instrumentation necessary to ensure that the cooldown necessary to reduce the RCS pressure and minimize the release is initiated and appropriate for the actions ri described in the EOPs. It is noted that the entry criteaa for the E-3 EOP is based on the operator's review of the radiological conditions using the steam line radiation, condenser air ejector radiation or steam generator blowdown radistion monitors.
Given the importance of this diagnosis to the initiation of the cooldown actions necessary to mitigate a steam generator tube rupture in accordance with the applicable safety analysis for the plant, the ICAVP would have expected these monitors to be Reg.
Guide 1.97 Type A variables. A review of the MP3 Reg. Guide 1.97 compilance analysis and FSAR indicates that they are designated for monitoring only as Type E variables. This issue is of importance due the origirial compliance witt Reg. Guide 1.97 and the recent emphasis of diagnosis and response to steam generator tube rupture events to prevent overfill.
NU should address which, if any, of the identified Reg. Guide 1.97 Type A, Category 1 instruments has been designed to monitor this condition.

Deecript6on: This Modifichtk,,1 changed the start initiating circuits for HVR and SLCRS fans. Several anomalies in the described design and the current as-built plant could not be reconciled.
item 1 DCN DM3 S-1506-92 (page 6) Indk.ated that cable 3HVRCOC700 was to be wrapped with Sil Temp to resolve an apparent separation vlo!atlon. Field observation revealed that this cable was not wrapped, however, adjacent conduit floor sleeve was extended and no separation vlotation was observed.
No change documentation could be found to eliminate the requirement for wrapping of the cable.
Item 2 DCN DM3 S 1495 92 required the removal of wirirc, from TB-4, points 1 and 2 at Panel 3CES*1PNL120. The DCN was incorporated into revision 4 of panel drawing EE 3NV. The current revision of the drawing (Rev. 3) dot.s not show wires connected to these points and none of the outstanding change documents for the drawings add wires to these points. Contrary to this, a black wire is landed on point 1 and a white wire is landed on point 2.
Item 3 Changes required by this DCN DM3 S 1606-92 included: the removal of an intemal jumper from terminal block 3T71 and re-landed at point 7; and the relocation of an intemal jumper between 3T7 points 8 c.nd 9 to points 1 and 7. This DCN has been incorporated into the affected drawing (ES3PH) with the curTent revision (Rev.10) showing these changes. Field
-inspection found these changes not installed with the current field wiring as depicted in the 'before* diagram within the DCN.

Date Pubished: 1/25/96 D6ecropency: Calculation P(B) 1001, Rev 0 CCN 3 and CCN 4 Dacription: During review of Calculallon Change Number 3 and 4 to calculation P(B) 1001, Rev. 0 ' Heat Leads for the ESF Building Emergency HVAC Systems' the following discrepancies were identified:
Calculation Change Number 3:
- 1) On page 6, data item #1; a sump water temperature of 215'F based on reference 5 (calc US(B) 356, Rev.1) is used. This is in conflict with the 260'F sump water terr.perature stated in Safety Evaluation S3-EV 97-0045 prepared for DCR M3 96054,
- 2) On page 6 & 7, data item #2; uses a 230*F water temperature downstream of the safety injection pumps. This does not agree with page 92 of reference 5 that states that the temperature downstream of the safety injection pump is 240 'F.
- 3) On page 7, assumption #2; assumes that piping temperature will approach 230'F. This does not agree with the 260*F stated in 3afety Evaluation S3-EV 97-0045 item 1.1
- 4) Page 8, piping heat losses need to be recalculated using the higher pipe temperatures noted in Safety Evaluation S3-EV 0045.
- 5) Page 8, calc for 10" line with 1.5" of encapsulated insulation and 8" line with 2" of encapsulated insulation; states room temperature is 120*F but uses room temperature of 110'F when adjusting heat loss.
- 6) Page g, item 7 & Table 5; Heat gain of 14,430 Btu /hr for ACUS 2A/B fan heat gain (page 65 of original calc) needs to be added to totals shown in Table 5 for rooms 1 A & 1B Calculation Change Number 4:
- 1) On page 5 of CCN, item 2; the CCP leaving RHS heat exchanger water temperature of 142*F does not agree with reference 3 (SGCS Calc #95-052 Rev A). With a 115 'F CCP temperature entering the RHS heat exchanger, the leaving tcmperature is approximately 150 *F. The 142*F temperature used in the calculation appears to be based on a 10g - 110 'F CCP temperature.
- 2) On page 6 n' CCN, a two foot floor thickness was used for area 4E. Drawing EC-328 7 shows the floor thickness as three feet. Using the three foot thicknes increases the R value and reduces th; heat transfer thru the floor.
Eqted 1123/981 o3At PM Page1 of 2
Northeast Ut:16 ties ICAVP DR No. DR-MP3-098',
Millstone Unit 3 Discrepancy Rapoft
- 3) Or. page 6 of CCN, a value of 0.68 was used for the siirface condudance (still air film) for the wall and floor, it should have been used only for the wall, The surface conductance (still air film) for hast flow down thru the flo ar is 0.92. This increases the R value and reduces the heat transfer thru the floor.
- 4) Calculation assumes a grcand temperature of 50 'F. Based on review of average earth temperatures on page 11,4 of the 1991 ASHRAE Applications handbook, a ground temperature around 70'F would be a more appropriate assumption. This reduces the available temperature difference from 54 to 34 'F for a 1047 room design temperaturn,
- 5) Page 5 of CCN refers to a Reference 5. There is not a reference 5 identified in the reference section of the CCN.
- 6) in Table 3 for the 1rt 24" line in room 2A and 28, the linear foot factor from Table 2 should be 6.283 instead of the 6.383 used.

D6ecrepancy: Service Water Pumphotse Ventilation Calculation Discropancy Deecrt tion: The following calculations were reviewed to verify that the P
correct heat load from the service water pump motors were used in determining the service water pump room ventilation requirements:
Calculation P 198 Rev. O, dated July 10,1973, Ventilation -
Circulating & Service Water Pump House Calculation P(B)-901 Rev. O, dated 12/14/83,3HW*FN2A/28 Cycling Frequency Calculation P(B) 920 Rev. O, dated 12/14/83, Recommended Period of Operation of the Service Water Pumphouse Ventilation Recirculation Mode Calculation P(B)-925 Rev. O, dated 12/14/S3, Service Water Pumpi:ouse Ventilation Requirements The rev'sw ' identified the following descrepancies:
- 1) Calculation P-198 used 800 hp foi calculating the heat loss frem one service weter pump motor. Plant Design Data System (PDDSS data for service water pump 3SWP*P1 A and 3SWP*P1B states that the motor rating is 600 hp v1th a brake HP requirement of 5.8.5 hp.Two pumps operate per. LOCA per FSAR section 9.2.1.2 while the calculation only considered one operating. This would resu't in higher than calculated heat loss to the pump room imm the service water pump motors.
Calculation P(B)-901 Indicates that P(B)-906 supersedes calculation P-198, However, calculation P-198 is still sh7sn as an active calculation in the calculation database and P(B)-906 has been superseded by P(B) 925.
- 2) Calculation P(B)-901 considered only one pump operating with a bhp of 561, Two pumps operate post-LOCA per FSAR section 9.2.1.2 which would result in higher thaa calculated heat loss to the pump room from the service water pump motors.
- 3) Calculation P(B)-920 considered only oe pump operating while two pumps operate post-LOCA per FSAR section 9.2.1.2
- 4) Calculation P(B)-925 used motor load values from calculation P(B)-901 which only considered one pump operating. Per FSAR Section 9.2.1.2, two pumps on the same division are required to operate post-LOCA.
The discrepancy is assigned a significance level 3 because the discrepancy may result in a higher Servive Water Pumphouse p?"') =0-'!0mp0=!=0 th0n th0 d d;;n M& t0mpc=gth w 2 p

Dele: 1/14/98 REs0LUTION: NU has concluded that Discrepancy Report DR MP3-0029 has identified a condition not previously discovered by NU which requires correction.
The calculations will be revised to correct this condition.
Condition Report (CR) M3-97 3283 was written to provide the necessary corrective actions to resolve this issue Based upon a preliminary Engineering Evaluation which considered the additional heat load from a second purnp in conjunction with the lower BHP requ:rement, there exists a sufficient ma' gin in the ventilation system to support the preliminary conclusion that the system will meet its design requirements. Once the calculation have been finalized a supplemented response will be provided confirming the results. NU concurs that until further analysis is completed and evaluated, this is a Significance Level 3 discrepancy.

containment purge Isolction valves 3HVU*CTV32A/32B/33A/333 closure time was noted.
FSAR Change Request FSARCR 97 MP3-4 increases the required containment purge isolation valve closure time from the value of 3 seconds given in FSAR Section 15.7.4.2.2 and FSAR Table 6.2 65 to less than or equal to 3.89 seconds. This increase in required valve closure tims is incorpora'ad in the purge isolation time presented in the Technical Requirements Manual (TRM) Section 3TRM 3.3.2 (page 5 of 6)
TRM Table 3.6.31 (ptge 5 of 9) of the Technical Requirements Manual, which references FSAR Table 6.2 65, Indicates a required valve closure time of 3.0 seconds.

NU has concluded that the issue repoded in Discrbpancy Report.
DR MP3-0115, does not rcpresent a discrepant condition. TRM Table 3.6.3-1 has been changed, effective 8/27/97 (Revision 6) prompted by continuing revisions to the calculation. The change eliminated the stroke time column.
Note 3 cf Revision 4 indicates that the stroke time value is the surveillance limit (see attached copy of 3613F.21) and may be more limiting than other documents.- TRM-3.3.2 is a clarification of response times for Tech Spec 3.3.2 ESF actuation signals, not the Surveillance limit.
This is not a discrepancy as the 3 second requirement of 3.6.3-1 is a surveillance limit set up to intentionally be more conservative than Tech Specs, TRM-3.3.2 and the FSAR.

FSAR Table 1.8-1, Regulatory Guide 1.52, paragraph C.3.d clarification states that the HEPA filters will be subjected to velocities recommended by the HEPA filter manufacturer which exceeds ANSI N509-1976 Section 4.3.1 requirements.
Specification 2170.430-065 identifies a 1500 cfm rated airflow for the HEPA filter which corresponds to a 9,000 cfm maximum airflow for the unit.
i FSAR Table 6.2-63 states that the clean HEPA filter pressure i

Millstone Unit 3 Discrepancy Report As stated in the closure request, although the current stocks of charcoal were initially tested at a face velocity of 40 FPM, routine surveillance testing, performed at a maximum face velocity of 48 FPM for all applications, has indicated the acceptability of the existing charcoal. Because the testing is completed on a representative sample, all charcoal from that procurement lot, includirg charcoal rtored in the warehouse, is validated.
Future procurement of charcoal will require Engineering review prior to ordering due to a HOLD against the stock code number (see attached printout from Material Information Management System, MIMS). This review will be done to the requirements of Specification 2170.430-065.
