Date Published: 11/2/97 Duropency: Cable Routing is Not Consistent With TS02 Deecription: Conduit 3CK768PB-4' runs between MCC 3EHS*MCC184 and the tray system above the MCC providing transition of cabling to the supplied components. There are three "K" service level 480 V power cables in this condult. These cables exit sis conduit with at least one of the caules entering a tray marked in the field as 3TC768P - a 120V control ("C" service level) cable tray.

This marking appears to be consistent with the tray arrangement drawings. The TSO2 routings for all three of these cables show that these cables are all routed into 3TK768P - a 480V power cable tray. The routing of higher energy cables (480V) in lower energy trays is generally not done, The Cable / Raceway Control Program Users Manuals indicates that "C" cables may be routed in "K" trays on a limited basis, but does not allow 'K" cables in

'C' trays.

The routing of power cables in control trays could adversely affect all control circuits with cables routed in the tray in the event of the power cable / circuit malfunction. Such a condition has the potential to render several components of multiple systems within the train inoperable.

Motor Operator Replacements for Valves 3QSS*MOV34A and 3QSS*MOV34B Motor operated valves 3QSS*MOV34A and 3QSS*MOV34B were changed from the original purchase specification from 0.13 to 0.33 horsepower. Neither Specification 2382.200-184 Add.1 nor Production Maintenance Management System (PMMS) have been revised to reflect the changes in horsepower, motor torque, full load current, and locked rotor current to valves 3QSS*MOV34A and 3QSS*MOV348. These documents should be revised. The affected voltage and thermal overload sizing Calculation 89 094120E3 (Rev. O, CCN 4) has evaluated both horsepower values, therefore the results of the calculation are not affected.

B. Reliance Motor Curves for Valves 3QSS*MOV34A and 3QSS*MOV34B 1, Fullload current can be obtained from the Reliance motor curve sheet (included in the motor operated valve calculations) in three places: the table, the header, and the curve itself. The values from these three places are usually different. In most cases, the motor operated valve Calculation 89-094120E3 (Rev.

O, CCN 4) states that the full load current is obtained from a walkdown reading of the nameplate, therefore the full load current data shown in the Reliance motor curve sheet is not used. However, for valves 3QSS*MOV34A and 3QSS*MOV348, the thermal overioad heater analysis section of the calculation states that the full load current value was obtained from the Reliance motor curve sheet, but no indication is made to whether the table, the header, or the curve itself was used to obtain this value. The different fullload current values are:

Reliance Motor Curve - curve = 0.73 amperes Reliance Motor Curve - header = 1.0 amperes Reliance Motor Curve table = 0.7 amperes Value used in the thermal overioad relay sizing section of the calculation = 0.73 amperes.

The use of 0.7 amperes has no affect on the calculation. The use of 1.0 amperes reduces the actuation time of the thermal overload relay but the results of the calculation are not changed, Printed 10/31197 to 01:10 AM page 1 of 3

Northeast Utilities ICAVP DR No. DR-MP3 0347

- ministone unit 3 Discrepancy Report namely that the thermal overload relay aduates prior to reaching the motor's capability but after the valve actuator motor duty cycle.

Calculation 89-094-1RE3 uses different full load current values (0.73 or 1.0 amperes) in 'he AC Motor Evaluation Checklist, Limitorque EEQ Walkdow,' Check!!st, motor overioad test record, and molded case circuit breaker test record sheets, in add!'lon, the full load current values are different between the calculation, vendor Drawings 2382.200-164 -043 (Rev. C) and '

2362.200-164-043A (Rev. B) (0.95 amperes) and Plant Design Data System (PDDS) (1.0 amperes). These documents should be revised to reflect the actual full load current.

2. For motor operated valves 3QSS*MOV34A and 3OSS*MOV348, the Reliance motor curve in Calculation 89-094-120E3 (Rev. O, CCN 4) indicates a locked rotor current value of 5.5 in the header of the curve but a locked rotor current value of 5.25 in the table of the curve. The calculation doesn't address which value is u ed or why it is used. In addition, Calculation 89-094120E3 does not match the values shown in vendor Drawings 2362.200164-043 (Rev. C) and 2362.200-164-043A (Rev. B)

(5.0 amperes) and PDDS (5.8 amperes). The adual value of the locked rotor current should be used in these documents.

Calculation 89-094-120E3 used the value of 5.5 amperes in the thermal overload relay sizing and in the overload sections of the calculation. This provides more conservative results than using 5.25 amperes.

C. Motor Ampacities of Valves 3QSS*MOV34A and 3QSS*MOV348 For motor operated valves 30SS*MOV34A and 3OSS*MOV348, Production Maintenance Management System (PMMS) has three ampacity categories and values for two ampacity attributes:

AFL = 0.39 ALR = 2.6 Amps = 0.13 Comparing the values in PMMS with other documents, "AFL" and "ALR" represent full load and locked rotor current, respectively, it appears that " Amps" represents the old horsepower of 0.13. " Amps" should be revised to reflect the actual motor attribute and value.

D. Stroke Time for Valves SQSS*MOV34A and 3QSS*MOV34B Motor operated valves 3QSS*MOV34A and 3QSS*MOV34B have stroke times which are not consistent between Calculation Main 97 Dau ~ 9 and nithmr nnarmentinn ov9 onrL1 A1 AMA 1 nr

Celculation 89-094 120E3 is used to size the motor thermal overloads and confirm adequate voltage exists at the motor's terminals. The stroke time in Calculation NM-027 is 40 seconds for these valves. The stroke time in Calculation 89-094-120E3 is 30 seconds and the stroke time in Specification 2362.200-164 Add.1 is 30 seconds (maximum). The 40 second stroke time does not affect the results of the calculation (i.e., the thermal overload relay will not actuate within 5e duty cycle of the valve actuator motor).

In the thermal overload analysis section of Calculation 89-094-120E3, it references Calculation NM-027 as the input source for stroke time. Calculation 89-094-120E3 references Revision 1 of Calculation NM-027, but the latest revision of NM-027 is Revision 2. The latest revision of NM-027 should be referenced.

C) and 2362.200164-043A (Rev. B) (5.0 amperes), Specification 2362.200-164 Add.1 (2.6 amperes), and PDDS (2.6 amperes).

These documents should be revised to reflect the actual motor data.

2. For each motor operated valve, the header on the Reliance motor curve iefers to the insulation as "B" which does not agree with the purchase specifications which require an insulation rating of radiation resistant Class H.

3. In Calculation 89-094-120E3 (Rev,0, CCN 4), the locked rotor current for valves 3RSS*MOV20A,3RSS*MOV208, 3RSS*MOV20C, and 3RSS*MOV200 t sries between 5.25 amperes as shown in the table on the nellance motor curve M2734 (dated 7/25/77) and 5.5 amperes which is shonm on the undervoltage analysis, thermal overload heater analysis, AC motor evaluation checklist, and thermal overload relay checklist of the calculation. However, Calculation 89-094-120E3 only uses the 5.5 ampere value throughout its analyses (i.e., is consistent). This value results in a more conservative but acceptable voltage drop than when using 5.25 amperes. The use of either value meets the requirement that the thermal overload relay actuate before reaching the motor capability.

4. In Calculation 89-094-120E3 (Rev. O, CCN 4) for valves 3RSS*MOV20A, 3RSS*MOV208, 3RSS*MOV200, and 3RSS*MOV200, the Reliance motor curve shows a horsepower rating of 33 and the Limitorque EEQ Walkdown Checklist, motor overioad test record, and molded case circuit breaker test record sheets of Calculation 89-094-120E3 show a horsepower of 0.125 which does not match the value of 0.33 horsepower used in the undervoltage and thermal overioad heates analysis of the calculation. These documents should be revised to reflect the actual motor horsepower.

5. Fullload current can be obtained from tne Reliance motor curve sheet (included in the motor operated valve calculations)

Northeast Utilities ICAVP DR No. DR MP3-0368 i Millstone unit 3 Discrepancy Report values from these three places are usually different. In most cases, the motor operated valve calculation states that the full load current is obtained from a walkdown reading of the nameplate, therefore the full load current data shown in the Reliance motor curve sheet is not used. However, for valves 3RSS*MOV38A, 3RSS*MOV388, 3RSS*MV8838A, and 3RSS*MV88388 the calculations state that the full load current value was obtained from the Reliance motor curve sheet, but no indication is made to whether tha table, the header, or the curve itself was used to obtain this value. The different full load current values are shown below for these valves:

Valves 3RSS*MOV38A and 3RSS*MOV388:

Reliance Motor Curve - curve = 2.1 amperes Reliance Motor Curve header = 2.3 amperes Reliance Motor Curve - table = 2.1 amperes Value used in Calculation 89-094117E3 (Rev. O, CCN 2) = 2.1 amperes (if 2.3 amperes is used in the calculation, the thermal overload relay actuation time decreases but it still meets the requirement to actuate after the 40 second valve actuator motor duty time but before the motor capacity which is 793 seconds.)

Valves 3RSS*MV8838A and 3RSS*MV8838B:

Reliance Motor Curve - curve = 4.5 amperes Reliance Motor Curve header = 5.2 amperes Reliance Motor curve table = 4.7 amperes Value used in Calculation 89-094112E3 (Rev. O, CCN 2) = 4.5 amperes (if 4.7 or 5.2 amperes is used in the calculation, the results are unchanged.)

The valves listed below show differences between the Reliance motor curve header, table, and curve full load current values, but the full load current value used in Calculations 89-094-332E3 (Rev. O, CCN 2) and Calculation 89-094-120E3 (Rev. O, CCN 4) was obtained from the nameplate (i.e., the Reliance motor curve full load current data was i.ot used in the calculations).

Valves 3RSS*MV8837A and 3RSS*MV8837B:

Reliance Motor Curve - curve = 4.5 amperes Reliance Motor Curve h6ader = 5.2 amperes Reliance Motor Curve - table = 4.7 amperes Value used in Calculation 89-094-332E3 = 4.5 amperes (if 4.7 or 5.2 smperes is used in the calculation, the results are unchanged.)

Valves 3RSS*MOV20A,3RSS*MOV208,3RSS*MOV200, &

3RSS*MOV200:

Reliance Motor Curve - curve = 0.75 amperes Reliance Motor Curve - header = 0.75 amperes Reliance Motor Curve - table = 0.7 amperes Value used in Calculation 89-094-120E3 = 0.75 amperes (If 0.7 amperes is used in the calculation, the results are

DiacropeWY: Design Document Discepancies Resulting from RSS Valve Operator Replacements Ducription: Motor operated valves 3RSS*MOV20A,3RSS*MOV208, 3RSS*MOV20C, and 3RSS*MOV200 were changed from the horsepower of 0.125 shown in the original purchase Specification 2362.200-164 Add.1 to 0.33 horsepower. Not all of the design documents reflect the latest changes.

The AC Motor Evaluation Checklist, Limitorque EEC Walkdown Checklist, motor overload test record, and molded case circuit breaker test record sheets (pages 9 through 24 in Attachment 3) of Calculation 89-094-120E3 (Rev. O CCN 4) have not been revised to reflect the changes in horsepower, motor torque, full load current, and locked rotor current to valves 3RSS*MOV20A, 3RSS*MOV208,3RSS*MOV20C, and 3RSS*MOV200, even though these valves were replaced in 1985. The latest change notice (CCN #4) still reflects these pages as valid (i.e., they are not noted as being void nor is there a statement that they will be replaced in the future). Both PDDS and PMMS refer to the replacement valves as being provided by Specification 2362.200-164 Add.1 (same as the originally purchased valves), but this specification still references the horsepower, full load current, locked rotor current, and torque of the originally purchased valves even though the vendor drawings reflect the horsepower of the replacement valves (0.33 HP). PDDS has not been revised to reflect the change in the valves' horsepower, full load current, and locked rotor current. The vendor drawings reference the old torque value (2 ft-Ibs) and different full load and locked rotor currents than the calculation or PMMS.

Calculation NL-038 (Rev. 2, CCN 6) references the old motor (0.13 horsepower and 3.15 locked rotor amperes). These documents should be revised to reflect the latest motor data.

Deseropeney: Stroke Time Discrepancies for RSS Motor Operated Valves Dacropeen: Motor operated valves 3RSS*MV8837A,3RSS*MV88378, 3RSS*MV8838A, and 3RSS*MV88388 have stroke times which are not consistent between Calculation NM-027 Rev. 2 /

purchase Specification 2280.050-878 (Rev.1) and motor operated valve Calculations 89-094-332E3 (Rev. O. CCN 2) / 89-094112E3 (Rev. O, CCN 2). Calculation NS027 Rev. 2 and Specification 2280.050-876 have stroke times of 10 seconds but Calculations89-094 332E3 and 89-094112E3 have stroke times which have been revised in CCN 2 to 12 seconds. Since these calculations conside' lon0er stroke times than Calculation NM-027, their results tre conservative.

Calculation NM-027 Is the 90veming calculation for stroke times because the thermal overload setting Calculations 89-094112E3 and 89-094 332E3 reference NM-027 as their input source for stroke time. The stroke times for 3RSS*MV8837A, 3RSS*MV88378,3RSS*MV8838A, and 3RSS*MV8838B are shown in Calculations 89-094112E3 and 89 094 332E3 as 10 seconds in the installed condition and 12 seconds for the proposed valve replacement. Althou9h the 12 second stroke time is shown in Calculations $9-094112E3 and 89-094 332E3 as a.1 input from Calculation NM-027 Rev.1, a review of NM-027 Rev. 2 ' hows that the stroke time is still 10 seconds. Therefore, Calculations 89-094112E3 and 89-094 332E3 do not agree v.ith the value of stroke time used in Calculation NM-027 nor do they reference the latest revision (Rev. 2) of Calculation Nhn 027.

Date published: 11/247 D6 crepency: Design input Discrepancies involving 4KV Motors De*cr6 P 44an: 1, in Calculation NL 033 Page 17 (Rev. 3, Rev.1), the brake horsepower M for motor 30SS*P3A is 380. Specification 2214.602-040 Aud. 8 (" Centrifugal Pump Data Sheet") uses 386 as the brake horsepower. Using the data from the Installation, Operation and Maintenance Manual OIM-009-007A, Performance Curve 721,7C4 and the test log in Attachment B of Calculation NL 033, the brake horsepower is 386 [(4000 gpm

• 291 ft ' 1.0 SG) / (3960

• 0.760)]. (The pump curve in Calculation NL 033 Attachment B is in increments too small to accurately determine the brake horsepower.) The value of 380 used in Calculation NL 033, and subsequently by Calculation SP.

MS-EE 342 (Rev.1), leads to less-conservative results than if the vendor supplied value of 386 was used. The effed of using 386 BHP instead of 380 BHP does not affect the results of Calculation NL 033 as it increases slightly the steady state KW load by 5 KW to 5147 KW, which is within the emergency diesel generator's rating of $221 KW, Calculation NL 033 should be iev;4ed to reflect a BHP of St.6 for 3QSS*P3A.

2. In the OPAL database Calculation 6P M3-EE 342 (Rev.1),

Section 3.5 (Load Data Table), the BHP used for the QSS and RSS pump motors is the rated or normal BHP (380 and 450, respectively) but the BHP for the SWP pump motors is the maximum BHP (561). In Calculation SP M3 EE 342, Section 4.9 (Motor Data Log), the BHP used for the QSS and RSS pump motors is the maximum BHP (470 and 458, respectively) but the BHP used for the SWP pump motors is the rated or normal BHP (555). The calculation should be revised to be consistent in its use of BHP for the 4KV QSS, RSS, and SWP motors.

Use of the maximum BHP will provide more conservative results than using the rated BHP. Maximum BHP is not required for loading studies at this time because: 1. Calculation SP M3-EE.

342 is not set up for emergency diesel generator loading (which might require the maximum BHP if it does not model all QSS, all RSS or all SWP pumps as 'on"); 2. Calculation NL 038 (Rev. 2, CCN 8), which is used to determhu, voltage levels at electrical gipment, models all 4KV QSS, RSS, and SWP pumps on at b same time (i.e., the model does not require the maximum BHP for a "run out' operating condition), therefore, use of rated BHP is appropriate, Review vand inve86d Needed Date initiator: Kennes.D.J.

1. For motors 3SWP*P3A and 3SWP*P3B, vendor Drawings 2332.502 042-018A and 2332.502-042 019A ref$r to the i insulation class as 'H* which disagrees with the Class B rating shown in Specification 2214.432-042 Add.1 (Rev.1) and Plant Design Data System (PDDS). (Note that PDDS references 2214.432-042 as the P.O. even though the veredor drawing number has the base number *2332.502* which is associated wMh the Service Water Pump P.O.)

2. Motors 3SWP*P2A and 3SWP*P2B are included in purchase Specification 2214.432-042 Add.1 (Rev.1). The motor data sheet (Page 217 of the specification) has data which is different than either Vendor DrawinD 2332.502 042 019A or Vendor Drawing 2332.502 042-012A. The data which is different is:

Specification 2214.432-042 fullload current = 13.6 amperes; locked rotor current = 81.3 amperes; frame = 215T; speed =

1745 RPM; insulation = B Vendor Drawing 2332.502 042 019A fullload current = 13 amperes; locked rotor current = 78 amperes; frame = 254T; speed = 1760 RPM; insulation = H ,

Vendor Drawing 2332.502 042-012A fullload current = 13.5 amperes; 'ocl** eotor current = maximum of 6 times full icvf current; frame !15; speed = 1745 RPM; Insulation = 8 The two vendor drawinos are identified with the same Westinghouse S.O.#, Mark #, and Customer Order W.

The data for currents and insulation class in Plant Design Data System (PDDS) and Production Management Maintenance System (PMMS) match the specification, but the data for speed matches Vendor Drawing 2332.502 042 019A (PDDS and PMMS do not have data for the frame).

Neither vendor drawing is identified as " superseded *.

These documents should be revised to reflect the actual motor data.

Date Published: 11/2/97 06screpency: Calculation Discrepancies involving SWP Non-Reversing Motors tascripa6en: 1. Calculation SP M3-EE 342 (Rev.1) assumes that. *where B.H.P., efficiency, power factor and rated voltage values are not available from the project documentation' (Appendix B. Page B2), brake horsepower (BHP) is equal to the nameplate horsepower, efficiency is 0.92, and the power factor is 0.88 for 460V motors. However, for the following 460V motors, the project documentation is available for this data but was not used

> in the calculation:

Motors 3SWP*P3A and 3SWP*P3D have an efficiency of 0.84 and a power factor of 0.88 as shown in Plant Design Data System (PDDS) and a BHP of 7 as shown in Specification 2214.432-042 Add.1 (Rev.1) and PDDS.

Motors 3SWP*P2A and 3SWP*P2B have an efficiency of 0.84 and a power factor of 0.80 (per Vendor Drawing 2332.502-042 012A) or 0.82 (per Specification 2214.432-042 Add.1 (Rev.1)

Page 217 and PDDS). These motors have a BHP of either 7.55 (per Specification 2214.432 042 Add.1 (Rev,1) Page 217) or 7 (per PDDS).

Motors 3SWP*STRI A,3SWP*STRIB,3SWP*STR1C, and 3SWP*STR1D have an efficiency of 0.79 and a power factor of 0.77 as shown in Specification 2332.515-063 Add 4.

Since the actual brake norsepower of 3SWP*P2A,3SWP*P28, 3SWP*P3A, and 3SWP*P3B is less than thet assumed in the calculation, the results of Calcu!ation SP M3 EE 342 are conservative. The data listed above for SSWP*STR1 A, 3SWP*STRIB,3SWP*STR10, and 3SWP*STR1D have no effect on the results of the calculation.

Since the actual motor data is available, either Calculation SP-M3-EE 342 should be revised to reflect this data or the statement in Appendix B Page B2 of Calculation SP M3-EE 342 should be revised.

2. There is a discrepancy in the minimum required voltage for 3SWP*TV35A and 3SWP*TV358. Calculation 209E (Rev. O, CCN 2) Page 8 states that the minimum required voltage is 97 volts (this value is discussed in the telephone memora., "um attached to Calculation 209E as Page 79). Specification 2472.110-185 Add.1 (Rev. 4) Page 1 12 requires that the motors operate with a minimum required voltage of 85% of rated Printed tof31/9710.07.00 AM Page 1 of 3

O Northeast Utilities ICAVP DR No. DR-MP3 0447 Millstone Unit 3 Discrepancy Report l value, which equates to 102 volts. This is the value that is used  !

In Calculation 210E (Rev. O, CCN 1) Page 86. These calculations should be revised to refied the minimum rated voltage. Since these sduators were procured from the same ,

i vendor and specification, their ameptance criteria should be identical.

The minimum calculated voNage for motor 3SWP*TV358 is i 104.8 volts as shown in Calculation 209E Page 6. The vohage used for MCC 3EHS*MCC182 (which feeds 3SWP*TV358) is shown as 430 volts (Page 8 of the calculation), but Degraded Voltage Calculation NL-042 (Rev. 2 CCN 5) now shows this MCC to have a voltage of 424.8 volts. Using the NL 042 MCC voltage results in a motor terminal voNage of g9.6 volts, which satisfies the minimum voltage requirement of 97 volts shown on Page 6. l l

The minimum calculated voMage for motor 3SWP*TV35A is l 102.5 volts as shown in Calculation 210E Page 86. The voltage l used for MCC 3EHS*MCC1 A2 (which feeds 3SWP*TV35A) is shown as 434 volts (Page 6 of the calculation), but Calculation NL-042 now shows this MCC to haw a voltage of 427.9 voHs. I Using the NL 042 MCC voMage results in a motor terminal l voMage of 96.4 volts, which does not satisfy the minimum l voltage requirement of 102 volts shown on Page 86 of l Calculation 210E nor does it satisfy the minimum voltage I requirement of 97 volts shown on Page 6 of Calculation 209E.

Note that Calculations 209E and 210E state that the calculation of record that determines the MCC bus voltages is NL-038. It appeam that Calculations 209E and 210E should be revised to use Calculation NL-042, which provides lower minimum voltages and is more conservative than Calculation NL-038, and not NL-038 for determining the MCC bus voltages.

3. For motors 3SWP*P1 A,3SWP*P18,3SWP*P1C, and 3SWP*P10, Calculation GM-60-03.405CA (Rev.1) shows an acceleration time of 6 seconds for a minimum starting voltage of 70% of rated voltage. This does not agree with the 5 second acceleration time shown in Specification 244t003-009 (Rev. 2)

Page 2 8 (the 6 second acceleration leads tu more conservative results in Calculation GM-60 03.405CA).

4. Calculation NL-033 Rev. 3 Page 17 shows two entries in the

" Safety Related Pump Table

• for 3SWP*P1 A/C. The first entry (the one with BHP = 591 and kW = 469) should read 3FWA*P1 A. This has no effect on the resul4 of the calculation for the service water pumps because only the data from the second entry was used in tha calculations.

Dale Putdished: 11/297 D6ecrepency: Calculation D!screpancleo involving RSS Non-Reversing Motors Descripason: 1. For motors 3RSS*P1 A,3RSS*P18,3R3S*P10, and 3RSS*P10, the locked rotor current in Calculation GM 03.409CA (Rev.1) is based on KVA Code Letter *F*, This code letter disagrees with the KVA Code Letter *D'shown on Page 5-14 of Specification 2214.802-044 (Rev.1), however since the calculation's value is greater than the specification's, the results of Calculation GM-60-03.409CA are still valid.

2. For motors 3RSS*P1 A,3RSS*P18,3RSS*P1C, and 3RSS*P1D the vendor motor curve 2214.802 044 023A shows an acceleration of 3.2 seconds for 70% of rated voltage. This agrees with Specification 2214.802-044 (Rev.1). Calculation GM-60-03.409CA (Rev.1) shows an acceleration of 3.2 seconds for 80% of rated voltage, therefore the acceleration is at a different voltage. The documentation should be revised to reflect the voltage associated with a 3.2 second acceleration (if 80% is the appropriate minimal voltage, then the

• minimum acceptable voltage" of 70% of nameplate voltage listed in Calculation NL-038 Page 13 needs to be revised). Either voltage ,

is technica!!y acceptable as the minimum voltage because the minimum voltage at 3RSS* PI A,3RSS*P18,3RSS*P10, or 3RSS*P1D is 3382 volts (reference Calculation NL-038, Rev. 2 CCN 6, Mode 7 Run 609) which is 85% of rated voltage.

3. Cfculation SP M3-EE 342 (Rev.1) states as an assumption that, 'where B.H.P., efficiency, power factor and rated voltage values are not available from the project documentation" (Appendix B, Page B2), brake horsepower (BHP) is equal to the nameplate horsepower, efficiency is 0.92, and the power factor is 0.88 for 460V motors. However, for the 460V motors 3RSS-P2A and 3R9S-P28, the project documentation is available for this data but was not used in the calculation. The data for these motors is 7.3 BHP normal / g.15 BHP maximum, a power factor of 0.87, and an efficiency of 0.84 (reference Specification 2225.202 050 Add. 6 Page 2-47 and PDDS), Since the actual brake horsepower is less than that assumed in the calculation, the results of Calculation SP M3-EE 342 are conservative.

However, since the actual brake horsepower is known, either it should be used or the statement from SP M3 EE 342 should be revised.

Date Published: 11/2/97 Diecrepency: Drawing discrepancies

Description:

The following drawing discrepancies are noted:

1. Support mark number #111 is shown as type R203A on drawing EE 34EE Rev. 6. The drawing does not list R203A in table of support types and the Cable and Raceway Program (TSO2) lists R203 for trays supports for trays 3TX 014N, 3TK007N and 3TC 013N, which includes support #111.

2. Drawing 12179-EE 46D, Rev 13, shows put! box '3JB 0161*

located in the containment at elevation 34 feet (drawing coordinates 1-6). This box is actually 3JB*0161. The non safety related box (3J3-0161) is located at elevation .18 feet.

3. Note 2 of Drawing, Indicates that all trays are 30 inches wide unless noted otherwise. Trays 3TC0014N,3TC0015N, and 3TX016N are shown on this drawing and without a commodity type indicating a different tray size displayed for these trays.

TSO2 indicates these trays are 18 inches wide The trays are depicted on the drawing similady to trays that are listed as 30 inches.

Date Published: 11/2/97 D6 crepancy: Conduit Support Differences Ducription: 1. While checking supports CS 7503 and CS 7445,it was noted that the conduit fitting cover for 3CX900PB4 was missing. The fitting's open face is upward. Location is near CS 7445.

2. An unidentified / unscheduled 2' con 6uit, which according to Conduit Support Log 12179-FSK-CS 3348, Rev. 6, is supported by support CS 3348,is not clamped on support CS-3348. The resulting span is over 10' 6* which exceeds the allowable span of 8' 0* per BE 52AN Rev. 5 and AU Rev. 4..

3. Field inspection of support R208A-098 found a section of 3/4 inch Steel conduit that is not clamped to the support, but is resting on conduit supported by R208A-098. This conduit is in need of support in this approximate location to meet span critoria and to take credit for the tray support supporting the conduit, a clamp / attachment is necessary.

4. Conduit Support Log (CSL)12179-FSK-CS-1343, Rev. 7, with no outstanding change documents, lists conduits 3CX900PA, 3CX900WB2, and 3CX900PC2 as supported by this support.

These condults are not included in TSO2 as supporied by this support. TSO2 lists an additional condult,3CX900PC, not shown on the CSL, as supported from this support.

5. Conduit Support Log (CSL)12179-FSK-CS-3058, Rev. 5, with no outstanding change documents, lists conduit 3CX900PA4 as supported by this support. This conduit is not included in TSO2 as supported by this support. TSO2 lists an additional conduit, 3CX900PA, not shown on the CSL as supported from this support.

6. Conduit Support Log (CSL) 12179-FSK-CS-4798, Rev. 2, without outstanding change documents, indicates that conduit 3CX9000B4 is supported from support CS-4798. TSO2 also indicates this conduit is supported by the support. The detail shown on the draw lng is for a field installed junction box and does not include any attachment of condult. Further. the conduit is installed in the field with two supports, CS-7482 and 7483 which are listed in TSO2 and the CSLs correctly.

i. Deectlpt6ca: 1. Field inspection of support R208A-0W found a horizontal section of PS-201 style strut attached tr. the side vertical member towards a work platform whit.h 15 not shown on the detail drawing EE 34HC Rev. 5. Note: the strut is not attached to work platform. No ooen documents discuss its add; tion.

! 2. Field inspecth i of support R204-105 found a vertical section of PS 200 styb strut attached below the bottom member.

-f Nothing is attached to this added piece. The detail drawing EE-34HC Rev. 5 does not show this member. No open documents discuss its addition.

3. Field inspection of support R150-055 found that the bottom tray shelf member is insimited at a 45 degree angle for proper fit-up to tray. This is not noted on the detail drawing EE 34HA Rev.

6 and is not covered by any listed open document.

4. Drawing EE 34T Rev. 1, indicates that all tray covers for instrument trays shall be flat. This is consistent with the tray detail drawing EF-34MJ Rev.3 and tray cover identification drawing EE 34TQ Rev. 2 which indicates top and bottom covers. The Cable and Raceway Program (TSO2) indicates that at least one of the covers for tray riser 3TX1n4P is vented. Field observation of the tray identified a vented cover on the bottom and flat on the top.
