The calculation Indicates this piping is it feet long. See Drawing EP 79K for pipe length. By not including this portion of pipe, the total developed head is underestimated which is not at:ceptable.

The flow rates for the De Waaring system are under 150 gpm for all line s!zes which include 1%',2",10" and 12" pipes. The calculation references Crane Technical Paper #410 for the head loss per 100 feet of piping. The papr provides head loss data l

for a 10" pipe starting at 475 gpm and for a 12" pipe starting at 700 gpm. The head loss is proportional to the square of the flow. The resulting head losses calculated using the square of the flow method are smaller than the values used.

Dkcrepency: Differences in Support Drawings and TSO2 Data Deecripth: 1. Drawing EE 34DT Rev. 7 (C-4) shows tray support A306 26 for Tray 3T1140. TSO2 does not list this support, but lists a A307 26.

2. Several tray supports do not have mark numbers - which provide for the unique identification r,f a support based on a standard support type and the specific location - shown on the support location drawings (EE 34-DX Rev. 8 and EE 34DY Rev.

8 ). Therefore,it is not possible to reconcile these supports with TSO2. Example: for tray 3TX214N, three type 'A10$* supports are shown-TSO2 lists the A105 supports as 47, 53,41.

(typical situation with 34DY).

3. F E 20188 adds conduits to tray support A104 however, the drawing was not listed as impacted and no mention of the additional conduit loads (no other conduits are supported from this support) for the tray support was made on any the drawing.

4. Trays 3TX703N and 3TX706N are vortical risers located in the Fuel Building. These trays are shown on Support Detail Drawing EE 34 HM, Rev. 3. The supports are direct attachment angles to embedded strut. The tray is installed in acCordance with the detail of the drawing. TSO2 does not list any supports for these l

tray risers.

For example in order to convert the calibration data of 17.664 mA (Data sheet page 8), to a pressure value and compare it with the acceptance criteria conteined in the TS of <=2385 psia the following calculations must be performed:

1mA=50 psi; Pressure Transmitter (PT455) offset =1700 psia (from Page 3 of Data Sheets. Including head correction);

Calibrated Pressure =1700+[(mA 4)x50]=2383.2(psia).

b) The Reference 1) Functional Diagram sheets contain a number of Notes. Some of these include a statement " Supplied by Others'. This does not reflect the MP3 as-built configuration.

Date Putdlehed: 1GM97 Diecrepancy: SLCRS Filler Housing Design Pressure De*criftion: During the review of the design pararr,eters for the Supplementary Leak Collection and Release System (SLCRS) filter units (3HVR*FLT3A/38) a discrepancy regarding the design pressure of the filter housings was identified.

FSAR Table 1.61 indicates that the filter units are in compliance with Regu!alory Guide 1.52, ReV. 2, position C.3 9 which requires the filter housings to be designed in accordance with the provisions of ANSI N5091976 Section 5.6.

ANSI N5091976 Section 5.6 states that the housings shall be designed and constnced to meet the structural and pressure loadings of Section 4. Section 4.6 identifies the following three pressure loading conditions: 1) Units and components that must withstand pressure transients,2) Units and components that must withstand fan peak pressure, and 3) Units and components subjected only to rated air flow, in accordance with ANSI N509-1976 Section 4.6.2.2, the SLCRS filter units must withstand a negative intemal pressure equal to er more negative than the peak pressure of fan 3HVR*FN12A/B since there are isolation dampers (3HVR*AOD95A/B) upstream of the SLCRS filter units.

Specification 2170.430-065 states that the filter housings are designed for 15 inches of water gauge (iwg) negative pressure.

The SLCRS exhaust fans (3HVR*FN12A/128) have a rated pressure of 22.2 iwg per Specification 2176.430141. Closure of the fire damper (3HVR*DMPF29,3HVR*DMPF44) downstream of the fan or of the air operated damper (3HVR*AOD95A/958) at the inlet of the filter housing could result an intemal housing pressure of 22.2 iwg which is greater than the.15 iwg design pressure for the housing.

Date Putdished: 1W3097 D6*crepancy: Drawing Discrepancies Dacrip16*n: 1. Drawing EE 37W Rev.13. (L 7) shows embedded conduits running between SWP pump rooms. The drawing indicates that conduit number 2 is spare, however, it is tagged and utilized in the field as 3DC880P02. Conduit number 4 shown as 3WC881N04 on the drawing was found to be plugged in the filed, however the Cable and Raceway Program (TSO2) Indicates cables are routed through this condult. GRITS shows no outstanding CCDs for this drawing and TSO2 does not show work in progress for these conduits.

2. Conduit Support Log 12179-FSK CW 172 Rev. 3A, fails to show the attachment of the strut used to clamp conduits to the support.

3. Conduit Suppor1 Log 12179-FSK CW-151, Rev.1, correctly indicates spare corKluit 3CX686NF is connected to support CW-151. However, the Cable and Raceway Program (TSO2) no longer lists conduit in the raceway tabulation for the support.

4. Conduit Support Log 12179-FSK CW 228, Rev.1, does not specify the type of strut Installed as the conduit attachment.

$. Conduit Support Log 12179-FSK CW 229, Rev.1, does not specify the type of strut installed as the conduit attachment.

6. Conduit Support Log 12179-FSK CW 247, Rev. 4, indicates that the supported conduit 3CX886ND2 is % inch diameter. This conduit at the point of attachment is 1 inch which changes to a %

inch after an installed LB fitting. The Cable and Raceway Program (TSO2) indicates this conduit is 1 inch

7. Conduit Support Log 12179-FSK CW 252, Rev. 4, does not specify the type of strut installed as the conduit attachment nor the bolts used for plate attachment.

8. Conduit Support Logs 12179-FSK CW 716 Rev. 3 and 718 Fav.1, do not specify the length of the strut installed (llem AU) to which the conduit straps, and thereby the conduit, are attached.

9. The Cable and Raceway Program indicates cable 3SWPAOC072 is 735 feet in length. The actual field installed length is estimated to be 135 feet. This significant difference would affect voltage drop calculation performed using the TSO2 dala.

1. Conduit MX000PB (1' diameter - steel) is supported by support ES 2100 as shown on Conduit Support Log 12179-FSK.

ES 2000 Rev. 2. This Is a direct attachment support type DC to concrete. Per Standard Support Detail Drawing BE 52CA, Rev.

4, the maximum allowable span to the next support is 5 feet.

Contrary to this requirement one of the as installed spans to the next support is 5' B'.

The following material condition items were noted;these are not configuration issues:

1.Several of the lower members of the cable tray supports in Manholes 3EMH 13A and 13B show significant signs of rust due to standing water which has also immersed the lower cable tray as demonstrated by the dis coloration of the cable with in the tray.

2. Electrical Installation Specification E 350 Raiv, g. Section 3.1.5.6 indicates that ducts (conduit embedded in ductbanksi shall remain plugged until cable is pulled and spare ducts atis sleeves shall be left plugged, Contrary to the above three conduit sleeves in each manhole 3EMH 13A and 13B, elevations 20' and 21' as shown Drawing EE 32L Rev. 7 (H 10) are not plugged / sealed.

Diecrepancy: Supports not in agreement with design drawings.

D**c<iption: The following deviations from design drawings were noted:

1. Drawing DWG EE 34KA Rev. 3 for tray support Type C207 calls for Detail H which requires Dusset plate at ceiling anchorage. Support C207172 does not have this detail as an auxiliary beam is installed in its position.

2. Drawing EE 34KH Rev. 2 for support type C260 does not show horizontal W37 5/8'L member that is installed between the top and bottom intema! 'X' bracing on support C260-263. Open Change Control Documents for this drawing did not authorized this deviation.

3. Three PS 204 memt,ers, which run to support C3t4 02, are installed on the upper 4 ft. section of the south verticalle0 of support C309A 017 (reference drawing EE 34 KP Rev. 4). No design documents can be identified to authorize these members.

• The third question is answered yes, with a footnote. The footnote states that a detailed ALARA review is not required, and is intialed RVK,12/13/94. The discrepancy is that the procedure was not followed, and that no justification was provided for bypassing the procedure, in this modification, it is clear to an experienced reviewer that an ALARA DESIGN review was truly not needed, and that the change w,'il actually reduce the dose in later outages. Therefore, the concem is not one of the effect of the design, it is, rather, what appears to be an unsupported capability to bypass a procedure.

10/15/97 INVALID: The ALARA design review form in the Design Control Manual (NUC DCM) permits the ALARA coordinator to make a judgement regarding the need for the detailed ALARA design review. This is apparently the process that was followed in the mod when it was concluded that the detailed review was not required. Therefore, the discrepancy is not valid (because the signature on the footnote indicates that the requirements imposed by the form in NUC DCM were followed.)
