PREFILED TESTIMONY OF C. THOMAS BRANDT REGARDING CASE'S FURTHER " EVIDENCE" OF A QUALITY CONTROL BREAKDOWN IN THE CONSTRUCTION, INSTALLATION AND INSPECTION OF THE STAINLESS STEEL LINER PLATE

01. Mr. Brandt, have you had an opportunity to review-the memo-randum concerning the stainless stoel liner plate filed by the Citizens Association for Sound Energy on November 15, 1984?

A1. Yes.

Q2. Mr. Brandt, directing your attention to page two of that memorandum, CASE contends that applicants incorrectly assert that the liner plate is not safety-relhted. Do you see that passage?

A2. Yes. It is set out in the first three paragraphs on the page.

03. Is that contention correct?

B411270320 841121 PDR ADOCK 0500044 s

,o, . w ,

A3.

'No. CASE's contention shows a' lack of understanding of rmr testimony _and the procedures applicabletto the fabrication and installation of'the stainless-steel-liner-plate. As:I

' testified -before, .the - fabrication and installation of the <

stainless steel liner have been designated safety-relate'd activities by the architect engineer.- I would likelto note my. testimony on this point appears at:page-45,315'of the transcript of this proceeding.

~

Therefore, CASE is'factu-

-ally incorrect when it asserts that applicants-have testi-fled that the. liner plate is not safety related. What-I testified to, and what CASE appears not to understand, is that'the welds in question are non-structural; this point is different from, and unrelated to, the fact that the ~

fabrication and installation of the liner plate are safety-related activities.

The significance of the welds being non-structural is that the architect-engineer did not iinpose stringent requirements such as those imposed by the ASME code, for the fabrication, installation, inspection and testing of the liner and the welding associated with these. activities.

The architect-engineer's only concern was that the welds not leak. Accordingly, welding on the liner place is not-now, nor has it even been, under the jurisdiction of the ASME Code.

Only two matters remotely tie the liner plate to ASME activities, but neither of these matters apply ASME fabri-cation and installation requirements to the-liner plate.

t i

,,_,..+w---, +w-* * " -+T^N -" " ^ ' '

=_ . = _

First, the' specification' for the liner _ plate requires that welders who work on, and welding procedures used.in connec-tion with, the liner plate'be qualified in accordance with Section IX of the ASME Code. This Section, however, is limited to the qualifications-of procedures and welders, and it is :not a fabrication code. Accordingly, the Code's fabrication requirements simply do not apply.to the liner plate.- Second, as an administrative matter, the inspection group originally assigned to perform these inspections was the ASME group. In February 1982, responsibility for these inspections was transferred to the non-ASME inspection group;.this transfer was also an administrative matter.

Again, I want to emphasize that these assignments were unrelated to the applicability of the ASME Code require-ments to the fabrication and installation of the liner plate.

Q4. Mr. Brandt, directing your attention to pages two and three of CASE's memorandum, CASE asserts that the correct traveler form was used for weld no. 988, and that you either were wrong in testifying that all travelers were initiated on the wrong form or that you knew that some travelers were initiated on the correct form and your testimony was deceptive. Do you see these allegations?

A4. Yes, I do.

05. Is CASE correct?

lll -

AS . . No.- First,-my; testimony.was that.I could find no' evidence that the correct traveler form was used before April 18, 1979. LMy. review of the travelers indicates that'the cor-rect' form was used after that.date. -Second, all of my testimony, ~as I have stated 'several times, is limited to-the travelers for the Unit 2 refueling cavity,'which is located inside the Unit 2 reactor building. All thirteen hundred travelers.at issue in this proceeding are for.that cavity. I would like to point out that I made this point on pages 15,921-923, 15,927 of the transcript.of this pro-ceeding. Traveller 988 cited by CASE is not for a weld lin this cavity. It is for a weld in the Unit 2 fuel transfer canal, which is located inside the fuel building. This is not only a completely different cavity; it is for a cavity located in a completely different building. -Thus, CASE's allegation is premised on a traveler that was not even included in the travelers that were the subject of my testimony.

06. Directing your attention to page 3 of Exhibit I to CASE's memorandum, CASE alleges that certain welds lack QC veri-fication of the fit-up and cleanliness of the outside welds. In support of this allegation, CASE identifies a total of 147 welds which it claims lack QC verification of the fit-up and cleanliness of outside welds. Do you see those allegations?

A6. Yes I do.

07. Have you reviewed the travelers for these welds?

A7. Yes.

013. -Why was documentation of the OC verification for this weld not found during your review?

A13. The weld has not been made. It is a weld between an angle and the top plate of the Leavity, which as of November 20, 1984, had.not yet been fit-up.

014.- CASE next' states on page four of Exhibit 1 that five welds lacked OC verification of fit-up and cleanliness for the outside welds prior to .'elding which allegedly renders their conditions indeterminate,_ contrary to procedure and 10 C.F.R. Part 50, Appendix B, Criteria V. Do you agree with this characterization?

A14. I cannot agree with CASE's position. I do agree with CASE's contention that, because of the dates of the signa-tures, the chits attached to these travelers do not det nitely establish that the five cleanliness and fit-up inspections were performed prior the time the backing strip was tack-welded to the plates. This is a violation of site procedures, and I have directed that an NCR be written to address this deficiency.

While I agree that there is a paper problem with these five travelers, I cannot agree that the deficiency is tech-nically significant. The fit-up of the plates associated with the travelers identified by CASE was reverified and documented and the cleanliness of the inside joint was verified and documented prior to making the inside welds.

Under these circumstances, the verification of the fit-up and cleanliness of the plates prior to tack-welding the

, = _ - . -

g.

~

, _ backing strip to the plates is not a technical. concern.

The only purpose of verifying the cleanliness of the' plates prior to. tack-welding the backing strip'to the plates was

~

to assure that'the backing strip could be securely tacked on an'd would not become dislodged inside the leak chase channel. The sole purpose for the inspection is to= ensure that the backing strip remains in place until the time of

-the inside f3t-up.- The reason for verifying fit-up prior to tack-welding the backing strip to the plates was to prevent difficult rework which would be required after the attachment of the leak chase channel if the original fit-up between the plates was out of tolerance. In any event, if' the backing strip had dislodged or if the fit-up have been improper those deficiencies would have been noted when the cleanliness and fit-up inspections were performed for the inside welds.

015. On page five of Exhibit 1, CASE identifies a number of welds which were done using welding procedure 88023 and i

claims that the carrect procedure for those welds was weld-ing procedure 88025. Do you agree with this assertion?

A15. No. The welds CASE identified are embed to plate welds.

All welds made on the liner plates between embeds and plates are groove welds in which the deposited weld metal thickness (joint thickness) is .1875" (the thickness of the plate). The proper procedure for making this weld in 1978 wa s W PS 8802 3, which was qualified for thickness ranges

.0625" through .750". Prior to October 15, 1979, WPS 88025 I

p_- - - -

1-

~

.e, was qualified .for1- welds Dith thicknesses of 0.75", through

3.5"..-on.0ctob'er!15, 1979',- WPS 88025 was revised and : the :

thickness . range was . expanded from: 0.75" :through 3.5" ;to

~

S

'~

0.185" through 3.50"..

Af ter this date either~ WPS 88023 or

'WPS ,88025 ' could ' have beenc followed when naking the welds to which CASE: refers. Therefore, CASELis wrong in contending:

that ; the wrong ~ procedure t was used . in making : the referenced -

welds.

To-confirm my-observations:on.this point, copies:of WPS 88023, WPS 88025 'and '1977 ASME ~ IX, QW 202.2 are append-ed to my testimony as attachments ~1, 2 and13,respectively.

016. On page six .of Exhibit :1, CASE identified 1243 travelers

~

which CASE claims. lack QC verification for Step 5, fit-up and cleanliness of the inside welds.- Have you reviewed the traveler packages .for these welds?

A16. Yes.

017. What was the-result of your review?

A17 It is difficult to understand CASE's allegations with ,

respect to the various welds includedoon the lists on page ,

6 of Exhibit 1 to CASE's memorandum. Initially, it is important to note that CASE's list includes five-line travelers and eight-line travelers. With respect to the  ;

five-line travelers, for example weld 6, the fifth line is for the final'V,.T. inspection, not for a fit-up and clean-liness inspection. Thus, CASE's allegations for the five-line travelers does not make any sense. In any= event, i

x IF 1 ,

-9 -

i 4

where the fif th line of the five-line traveler is unsigned,

~

it' simply means that weld is in process, and it does not reflect any paperior' technical' deficiency.

The eight-line travelers on:the list fall- into 'several categories. First, many of the travelers are for welds V-that are welded on one-side only_(welds 875, 896, 901, 908, 909, 910,.912, 682, 713, 714, 779, 783, 784, 785, 797,-798, and 799). For these-welds CASE's allegation is wrong n;

_because there is welding on only one side of the liner; consequently,.there are no fit-up or cleanliness inspec-tions to be performed on the second side of the liner.

Second, CASE is correct with respect to a small group of eight-line travelers (welds 12, 51, _ 5 9, 65,66, '7 2, 73, 90, 93, 107, 147, 203, 709, 851, and 907), and I have directed that an NCR be written identifying'the welds for which the inside fit-up and cleanliness inspections have not been ~

documented. Finally, my examination of all of'the remain-ing eight-line travelers on CASE's list reveals that CASE is factually wrong because the inside fit-up and cleanll-ness inspections were performed and documented.

017. On pages 7-8 of Exhibit 1, CASE lists twenty-seven (27) welds which CASE contends are missing the final V.T. of the inside weld. Have you reviewed this allegation 7 A17. Yes.

018. What conclusions have you drawn as a result of that review?

g A18..

.This is1another example of CASE's the fabrication and inspectioness. proclack of understanding CASE is~ correct in noting - that a final . visual inspection has ed for these welds, not been perform-bnt the-final visual-inspection has not .

been performed because.the welding /insp not been completed. ection process has My review of_the travelers indicates that no holdpoints have been bypassed

.and no violation exists for any of these welds.

Q19. Mr. Brandt, CASE also lists twenty-tt.o (22) weld s on page 8 for which WFMLs are not in the package.

Have you had an opportunity to review this allegation?

A19. Yes. However, the absence of WFMLs in< these trav l e er pack-ages does not constitute a violation of pr deficiency. ocedure or a There is simply no requirement specify ing that a copy of the applicable WFML is to be k traveler. I might also add, ept in each there is no requirement for filler metal traceability on any of th Q20. ese welds.

On pages 9-15 of Exhibit 1, CASE alleges that WFMLs are referenced on travelers done, indicating that new welding was but there the welding is done.is no QC verificationvolvementor in when Assuming this to be true, what significance does this allegation have?

A20.

Although I have not reviewed all the tr CASE on pages 9-15, avelers listed by believe that I have reviewed enough to lead me to this is another instance where oes CASE not d understand the requirements and/or the fab i sequence. r cation In all travelers I reviewed, no inspection hold-

~

required: inspections.are procedurally. described, Land'there-is-no requirement for' " verification" each day' welding is performed. From thelsample I reviewed, I am unable to detect any violation.

.021. Mr. Brandt, turning your-attention to pages116-20 of Exhibit 1,' CASE lists numerous welds for which welding was done, but no OC verification or involvement is shown, and

'that WFMLs are attached to, but not' references on, the travelers. What significance, if any, is there to this allegation.-

A21. None. Once again, as I discussed 'above, this-is apparently another instance where CASE is attempting to assert that verification of welding must be performed on each day that welding occurs. Of the travelers that I reviewed in connection with this allegation, all welds were still'in-l process, i.e., they had not yet received final inspection.

CASE's observation that WFMLs are attached to, but not referenced on, the travelers is correct; however, the alle-gation is without significance. This information is not

! required by specification, and serves no quality function.

The millwrights are procedurally required to enter this L

( information but they simply have not done so as of this I date.

e t.

Q22.' Mr. l Brandt, -CASE identifies 5' NCRs on page 21 of Exhibit 1 which describe welds for which- vacuum. box testing was improperly noted as not. applicable.

Is'there significance to this observation?

A22. No.

It was an error made. by the inspector, but,was proper-ly-reported and dispositioned on an NCR.

023. O

'n page 22, CASE lists' fifty-seven (57) welds which it alleges.are deficient because final V.T. has been performed ~

without vacuum box and/or. liquid penetrant examination being performed. Have you reviewed this allegation?

A23. Yes, I have.

024. What was the result of your review?

A24.

CASE apparently misunderstands the inspection testing ,

sequence. The final V.T. precedes the vacuum box testing and the liquid penetrant examination. As these welds-are clearly still in process, no holdpoints have been bypassed and no violation exists.

025. On the bottom of page 22, CASE notes "the final V.T. of'the inside welds were signed off on the following welds by other inspectors."

What is the significance, if any, of this observation?

]

A25. I am not quite sure to whom CASE is referring by the use of the phrase "other inspectors." I assume CASE is referring to the fact that the final V.T. has been performed by inspectors other than those who performed the P. T. and/or V.B. test. If this is CASE's allegation, it is without

w '

'9 1

merit!because, there is no requirement ~ that the same inspec-itor-perform V.T.land P. T . and/or vacuum box testing. No violation exists.

026. . Mr. Brandt, on page 23 of-Exhibit'1, CASE lists 131 welds which it alleges are~ deficient because~the " completion of weld inspection block on attachment 1 signed off as completed > prior to the completion on welds prior to [ sic]

vacuum box testing and/or P.T. inspection being performed."

!! ave you reviewed this allegation?

A26. Yes, I have.

027. What did your review indicate?

A27. The welds listed fall into several different categories.-

For a number of welds which CASE asserts that " completion of weld inspection block on attachment I signed off as i

completed prior to the completion on welds prior to [ sic]

vacuum box testing and/or P.T. inspection being performed,"

CASE is incorrect as the travelers clearly indicate that the weld is still in process. Wolds 5,

, and 8 are examples of this category. As the welds are incomplete, no violation exists. For a small group of welds, (weld numbers 1240, 1242, 1245, 1248, 1182, 1209, and 1210), CASE is correct and I have directed that an NCR be written identi-l' fying the condition as nonconforming. For all other welds listed on page 23, CASE is incorrect because the referenced tests are not required; there fore, no violation exists.

.y_ ,,,m --m ,

= '-

w Q28. CASE alleges on~pageftwenty-four of Exhibit 1-that-"[m]any:

NCR's were written .for welds that ' James Cole had N/A'd .the vacuum box test on. The vacuum box' test has been reestab-Lished on all but the.ones below." Have you had an oppor--

tunity to review this allegation and the travelers involved with' this allegation?

-A28. Ye s , I have.

029. What was the result of your review?

A29. Apparently CASE alleges that vacuum box was required for these welds. CASE lists eighty-eight (88) welds which it believe are deficient. As a result of my review, I have determined that with one excpetion (weld 932) that CASE's allegation is incorrect. All other wleds are not pressure boundary welds and therefore do not require vacuum box testing, and the step is properly marked not applicable

("N/A") on the traveler. I have directed that an NCR be written for weld 932 noting that the vacuum box test for that weld wns improperly marked "N/A."

030. Mr. Brandt, CASE alleges on the bottom of page twenty-four of Exhibit 1, that "PT test has been performed on these welds but vacuum box has not". Have you had an opportunity to review this allegation and the related travelers.

A30. Yes I have.

Q31. What were the result of.your review of these travelers?

A31. CASE lists an additional forty-eight (48) welds for which vacuum box has not been performed. For four (4) of'these welds (welds 1230, 1232, 1235, and 1238), CASE is correct

n.

.e and I have directed that an NCR be ' prepared describing this condition.' For all other welds listed here, CASE is incorrect; the step has properly.been marked'not applicable aus these . welds - do - not require vacuum box testing.

032. Mr. Brandt, directing your attention to page twenty-five of X Exhibit 1, in particular to. CASE's discussion of NCR M 01847 dated 7/7/83. CASE states that "The NCR was written in 1983 and a hold tag applied.- It has not been disposir '

I tioned yet, and there is no copy of this NCR in traveler 151. There is - no RPS in package for weld 154. 154 was signed of f by Don Vogt, S.M. McCoy, for steps 2, 3, and 4.

Jim Cole inspected 151 on 4/20/80 and 153 on 4/24/80."

What is the significance, if any, of these allegations?

A32. First, CASE is incorrect in stating that " ...it has not' ,

been dispositioned yet." In fact, CASE describes the ,

disposition of this NCR on page 25 of Exhibit 1. Second, original NCRs are not filed with traveler packages, nor does the lack of a copy of the NCR in package 151 consti-tute a violation of any code, standard, specification, or procedure. Third, CASE's observation thht no R PS is in i

package 154 is correct, but it is without significance for two reasons: first, the repair is not yet complete, and second, the repair, when completed, will be of weld 151, not weld 154, and accordingly a copy of the RPS will be in t package 151, not 154. Fourth, with respect to CASE's .

observation that " Jim Cole inspected weld 151 on 4/20/80,

[actually 4/2/803 and 153 on 4/24/80," CASE is apparently l

Weld 151 is a vertical weld which attgches'a plate (A35) to a gate gui<N. Although the vertical weld contin-ues on down the gate guide, .,it)is numbered differently for each plate it attaches. Welds 151; 155, 157, and 159 all form c the vertical weld which attaches a gate guide to s

plates A35, B35, M35 and M35, respectively. This weld

'(although 4 weld numbers) was fit up on 5/17/79. The back-

A34. Quite frankly, . I am unable to find that CASE alleges anything with regard to these two NCRs. Both identified problems, and both were properly dispositioned in accord-ance with: site procedures. CASE's note regarding the absence of a copy of the NCR in all of the packages is not l
