%i--~4~~'t~s~~~\ygy gG'78 l f396127 ABSTRACT This report contains the results of a field survey, through August 15, 1978 of Q-Listed supports with shop welds, made by ITT Grinnell s Warren Ohio fabrication facility, conducted by Bechtel Power Corporation and ITT Grinnell's engineering and Quality Control Departments.
The results are analyzed to verify the adequacy of the supports on the Susquehanna Project fabricated by ITT Grinnell in the fulfillment of Purchase Order 48856-P-3-AC'ev.
12, as committed to the NRC by Pennsylvania Power&Light.In total, five hundred sixty (560)Q-Listed supports have been surveyed and one hundred fifty two (152)are found to have portions of shop welds below the size specified on the support detail.These welds are analyzed for the"as-fabricated" stress levels using the smallest weld section found along the particular weld.The results of'his analysis show that all surveyed Q-Listed supports meet weld st'ress requirements of ANSI B31.1 and the stress acceptance criteria for welds.
(
gy 2Q'78-D" 6127 I.INTRODUCTION An agreement between Bechtel Power Corporation, Pennsylvania Power&Light and ITT Grinnell was reached to survey all of the shop welds for Q-Listed supports made at ITT Grinnell's Warren facility, and shipped prior to 10/18/77.ITT Grinnell agreed to compile and analyze each shop weld found in the surveyed assemblies with a non-conformance as defined by ITT Grinnell Quality Control Procedure OSQ-006 Rev.0, which was approved by Bechtel on February 7, 1978, based on the smallest section of weld found.The basis of this report intended to justify the acceptability of the referenced supports, by showing that none of the shop welds on these supports would be overstressed in the"as-fabricated" condition.
Since specific tolerances are not, re-quired by ANSI B31.1, or the design specification, it is ITT Grinnell's position that supports fabricated with shop welds slightly below the size specified on the design drawing should be acceptable provided no shop welds are overstressed in the"as-fabricated" condition.
NpY 2G'>8 G96127 II.METHOD OF SURVEY Prior to ITT Grinnell's inspection efforts, Bechtel had performed a preliminary survey of one hundred seventy two (172)Q-Listed supports.Of these, sixty-nine (69)were found to have weld sizes different from the design drawings.The results of this survey are given in Section IV of this report.ITT Grinnell has inspected three hundred eighty eight (388)Q-Listed supports.Of these, eighty three (83)were found to have weld sizes different from the design drawings, as defined by ZTT Grinnell Q.'A.Procedure SQ-006.All dis-crepancies were tabulated and forwarded to ITT Grinnell's Hanger Engineering Department for analysis.The results of ITT Grinnell's survey through August 3.5, 1978 are included in summary in Section IV of this report.For the.purpose of this report, a hanger requiring rework is defined as a support that has any shop weld that is over-stressed due to undercut or shallow size in the"as-fabri-cated" configuration.
III.METHOD OF ANALYSIS Weld stress calculations were'erformed for each Q-Listed support as required to verify that none of the shop welds were overstressed in the"as-fabricated" configuration.
These calculations were performed using the smallest section found, carried the full length of the weld.This represents a conservative approach, since very few of the shop welds questioned were undersize for the full length.Forces on the welds were determined in accordance with ITT Grinnell's Stress Criteria dated January 17, 1978, see Appendix D, which was approved with comments by Bechtel on March 9, 1978.The load'per linear inch was calculated and compared to the maximum allowable load per linear inch as specified in the above listed Stress Criteria.
~I~~*.IV;Anal sis of Results A.Weld size different from design drawing'isted below are the"as-fabricated" weld stresses for SO>2u'78'096127 the shop welds in question on the surveyed assemblies, the allowable load per the Stress Criteria for the"as-fabricated" size, and the" OC ratio" which is the allowable load divided by the actual calculated stress.All welds analyzed meet the maximum stress requirements of ITT Grinnell's Stress Criteria.Sketch 8 Shop Weld8 Load on Weld l7{/f/in.)DBB-209-H15 (Q)1 HBD-62-H10 (Q)1 DBB-209-H3(Q) 1 DBB-122-H5(Q) 1 H10(q)1 a8 (q)GBB-107-H14 sh.l(Q)l sh.2(Q)2 HBB-101-H2(Q) 1 GBB-118-H5(q) 1 H8(q)1 Hlo(Q)1 218-H5 (Q)1 DLA-102-H4 (Q)1 I HBB-101-H4 (Q)1 , GBB>>118-Hll sh.l(q)1'h.2(Q)2 GBB-107-Hll(Q) 1 II 2 3 HBB-108-82(q)

2-All welds included in the listing given in this section which have the comment"stiffener plate weld" are shown without a calculated stress since they aie secondary members.

-The undercut is on the knee brace which is not needed.The section modulus of a kf4xl3 is 5.24 and the design requires 2.18.Therefore, the'knee brace is not required'.

-The undercut is on the 1f-Beam weld to'he plate.The area of this member'is 3.81 sq.in.a.and it.has been reduced by.06 sq.in.Therefore, this undercut-'does not need any rework.c.GBB-101-H18

-The undercut is on the knee brace which is not required.The section modulus of a 4 M13 is 5.24 and the design requires 3.86.Therefore, the knee brace is not required.e.HRC-104-H2
-The undercut is at both ends of item II3 for a length of 1/4 of an inch.The maximum shear force at each end of item 83 is 5818.The surface area required to withstand 5818 is less than 1/2 inch., the surface area remaining with the undercut is.95 sq.inches.Therefore, this undercut does not need any rework.f.The following sketches have actual cross sectional areas or stresses less than required by design for the undercut material.No rework is required: GBB-101-H8 HRC-123-H3 HBB-110-H26 GBB-112-Hll GBB-107-H3 e DBB-115-H2 g.The following support, HBB-llO-H3, could not be evaluated due to inadequacy on the original design 3.We hav'e considered undercut welds in bending.The following sketches have the greatest moments that we have found during our survey,to date.Plate Sketch.Thickness No., Load~Re uited HRC-126-Hl 702 552 031" 594" Plate New Thickness Under-Plate DDesiDn Cut Thickness.625" HCB-102-Hl 340.289" 375".031 344" From the above finding, Grinnell concluded the undercuts in bending are all acceptable.

V.CONCLUSION Of the five hundred sixty (560)Q-Listed supports surveyed, one hundred fifty two (152)were found to have shop welds that were shallower than the size specified in the design detail.These shop welds were recorded, subsequently analyzed, and the actual stress in the"as-fabricated" con-dition compared against mutually agreed upon allowables.
The calculated safety margins (oCratio)ranged from 1.1 to 188-Through observation, it was seen that all welds were below allowables; therefore, none of the surveyed and analyzed supports have any shop welds which are overstressed.
As a result of this survey, all Q-Listed support welds on assemblies fabricated by ITT Grinnell and shipped to the Susquehanna jobsite have been visually inspected, calcula-tions performed and all welds have been found to meet all requirements.
ITT Grinnell concludes from this inspection that all Q-Listed supports shipped prior to-10/18/77 to the Susquehanna jobsite are totally suitable for the designed service.All as fabri-cated welds meet the requirements of ANSI B31.1 or the agreed upon stress criteria.'1
