AFFIDAVIT OF C. THOMAS BRANDT REGARDING "OPEN ISSUES" IN PROPOSED INITIAL DECISION I, C. Thomas Brandt, being first duly sworn to depose and state as follows: I am employed as the Non-ASME QA/QC Supervisor at Comanche Peak. As such, I am familiar with the QA Program at Comanche Peak, including the disposition of nonconforming conditions identified by QC Inspectors and the guidelines, specifications and procedures applicable to the QA Program. I have previously testified in this proceeding regarding the QA Program for Comanche Peak. A statement of my educational and professional qualifications 'was received into evidence as Applicants' . Exhibit 141A. This affidavit addresses certain "open issues" . identified by the Licensing Board in its July 29, 1983, Proposed Initial Decision. The particular "open issues" addressed herein concern (1) protective coatings, (2) downhill welding, (3) alleged mismatched pipe hanger, (4) bolt torquing, and (5) weld quenching.

, I. PROTECTIVE COATINGS j A. Inspection Procedures l There are four allegations which the Board identifies as l

"open issues" regarding the procedures applicable to inspection of protective coatings. Proposed Init.ial Decision at 23. I address each of these items below.

1. Near White Blast The Board left open a question regarding an allegation that there were no standards for determining whether near White blast (a measure of surface cleaning / preparation of cteel prior to painting or coating) had been achieved in surface preparation for application of protective coatings. Ilowever , as provided in the attached procedure, preparation of substrate surfaces for primer application requires cleaning to an equivalent of near white blast conditions, in accordance with applicable specifications.

See CCP-30, " Coating Steel Substrates Inside Reactor Building and Radiation Areas," Section 4.1.1. (Attachment A). The referenced specification requires the use of a Keane-Tator Surface Profile Comparator (a device which utilizes a plate with various known surface roughnesses for visual comparison of surfaces) to determine near White blast. See OI-QP-ll.4-1, " Inspection of Steel Substrate Surface Preparation" (Attachment B), Section 3.3.2.c. Accordingly, this allegation is incorrect.

O

2. Maximum Roughness The Board left open a question regarding an allegation that there is no maximum value for surface roughness in the specifica-tions regarding steel substrate surfaces, and that the rougher the surface, the earlier the paint will " break down."

The procedure applicable to the inspection of surface roughness does provide that "no maximum profile [a measure of surface roughness] will be specified, providing that correct millage [ coating thickness] requirements can be obtained after primer application." See OI-QP-ll.4-1, Section 3. 3. 2.c .

(emphasis added) ( Attachment B) . If the millage requirements cannot be met, the coating is rejected and reworked. Thus, the question of maximum surface roughness is procedurally addressed.

Further, the claim that a profile depth greater than the minimum specified (1.0 mil) would result in an early breakdown of the paint is wrong. In actuality, a profile depth greater than the minimum specified would tend to increase adhesion of the coating to the substrate. The only detrimental effect of this condition would be to create a surface on which it was dif ficult to obtain uniform coating thickness. However, this occurrence is addressed by procedures requiring inspection utilizing dry film thickness

- gages.

3. Adhesion Testing The Board left as an "open issue" a determination as to the l

l significance of the allegation that all paint inspection had been l reduced to adhesion testing. In fact, protective coatings inside l

containment at Comanche Peak are both visually inspected and inspected for dry film thickness following finish coat application (in addition to the procedures applicable to inspection of surface preparation and primer application).

Additionally, the liner plant is checked for coating continuity.

Only if records for surface preparation and/or primer application are missing or discrepant, will destructive testing (i.e.,

4 adhesion tests and/or scratch tests) be performed in the area for which the records are deficient. Thus, the allegation is incorrect.

4. Repair of Minor Defects Another "open issue" concerns the allegation that the repair criteria for minor defects in protective coatings are inadequate.

Proposed Initial Decision at 24. Specifically, it is argued that numerous (i.e., minor), closely spaced defects would be classified as minor (rather than major) defects, and that a primer coat should be employed in such instances.

The hypothetical situation postulated in this allegation is highly unlikely to occur in that any occurrences which would result in extensive damage to a coating are not likely to be limited to small (i.e., less than one-half inch) damage. The minor defects which are addressed by these criteria (procedures) are those in which minor chipping or cutting may have been made in the coating. If in any area, either circular or linear, a one-half inch diameter circle could be completely inscribed at any point by the defect, the defect will be classified as a major

defect and appropriate repair measures will be implemented, including application of a primer coat following surface preparation before reapplication of the final coating. See CCP-30, Sections 4.4.2.8 and 4.4.2.9 (Attachment A). These repair procedures have been approved by the coatings manufacturer as being appropriate for repairing defects in coating surfaces.

Thus, the procedures address any defect likely to be identified in coatings, and the repair process for various types of defects are established / approved based on appropriate technical reviews of the processes.

B. Kelly Heaters Another open issue identified by the Board involves an allegation that the disposition of an NCR regarding the possible contamination of a painted surface by smoke from a heater being used to cure the paint was inadequate. Proposed Initial Decision at 24. Applicants were unable to find an NCR vritten by Mr.

Hamilton regarding Kelly heaters. Applicants did find an NCR (NCR-C-903) written by his supervisor on that subject (Attachment C). The disposition of that NCR was to wipe off the coated surface with detergent or an appropriate solvent-to remove any surface deposits (soot) left by the smoking heaters. That is the standard procedure for removing any non-embedded contamination or painted surfaces. Any contaminants that may have been embedded in the coating would be detected by the routine visual inspection in accordance with instructions for visual inspections. If any contamination was identified, the affected area would be rejected l

I l

and repaired prior to final acceptance of the coating. Thus, any contamination which may have been caused by the smoke would be subject to appropriate corrective action.

C. Westinghouse Coatings An item which the Board states it is " unable to evaluate" based on the present record concerns an allegation that coatings on Westinghouse-supplied components failed an adhesion test.

Proposed Initial Decision at 24. In this regard, the Board requests an answer to the questions of whether these pieces of equipment were safety-related and whether the paint will perform satisfactorily. In the first instance, Westinghouse, as the nuclear steam supply system supplier for Comanche Peak, conducts its own QA program in accordance with 10 C.F.R. Part 50, Appendix B for all components it provides to Comanche Peak. Coatings on safety-related (as here) Westinghouse supplied components are subject to the Westinghouse OA program. Those coatings are identical to those applied to other steel equipment at Comanche Peak, including satisfaction of tests for performance under design basis accident conditions.

II. DOWNHILL WELDING Another "open item" identified by the Board concerns the allegation that downhill welding was performed by Mr. Stiner at Comanche Peak. Proposed Initial Decision at 33-34. The open question identified by the Board is whether this allegation was limited to root and cover passes, in that I previously testified that downhill welding was permitted by ASME Section IX for root

- - _ _ - __a

9

~

_7_ ,

and cover passes (Applicants'-Exhibit 141 at 22-23; Tr. 4601-02). However, I also testified that Brown & Root welding procedures (which are applicable to the welding being performed by Mr. Stiner) do not permit downhill welding at Comanche Peak (Tr. 4601-02). Brown & Root welders are qualified to instructions and procedures which prohibit downhill welding.

Thus, any welder who performed such welding would have to willfully violate those instruction / procedures, a practice which would be a basis for termination. I am aware of no evidence that

.such a practice has occurred at Comanche Peak.

III. MISMATCHED HANGER Another "open question" identified by the Board concerns an allegation that a hanger which had .been QC inspected was

" mismatched" in that an excessive fit-up gap existed between the ,

tube steel member and the base plate of the support. Proposed Initial Decision at 39. This allegation was the subject of an NRC inspection, at which time it was determined that the support in question was an ASME Code' Class 3 support. The procedures applicable to the particular weld in question provided for a

fit-up gap of no more than 5/32 inch. As part of the NRC's investigation, a portion of the welded material was ground out to -

examine the fit-up gap. It'was determined that for at least a j s portion of the welded area a gap of 1/4 inch was present.

1 Accordingly, Applicants 11dentified]this support on an NCR, removed the af fected portions of the~ . pipe support (for

[ . . ,

I investigative purposes) and evaluated the safety consequences of-

/

8 . \, -

..G'

.c . _

.- , ~ ,. , , , . , . - . . , ,J

the nonconforming weld. That evaluation determined that even had the particular gap not been detected, there would have been no adverse safety consequences. See letter to G.L. Madsen (NRC) from R.J. Gary (TeWas Utilities Generating Company), TXX-3655

( April 15, 1983) ( Attachment D) . Furthermore, we have no reason to believe that this instance is other than an isolated case.

I V. BOLT TOROUING Another allegation which the Board has identified as an

' ~

"open item" concerns the establishment of torque values for A490 bolts. This allegation was that no specific torque value had been established by procedure for A490 bolts. (Proposed Decision at 43-44.). Actually, torque values for A490 bolts had been established. However, these values were based on an informal correlation of bolt tensicn with a particular number of turns of the bolt'to be made after ~ achieving a snug-tight condition. As a result of'~nn NCR (which was written against a bolt that had failed during tightening) , it was decided to establish A490 torque values based on formal testing. Consequently, a test was

.g

,s- performed to establish such values, and the actual test data were incorporated into the design specifications. Bolts which had

!< previously been verified by the prior torque value were

subsequently re'v erified to the new value. In addition, samples of the CB&I(furni hed bolts were taken and independently tested to verify mater'i<31 quality. .It should be noted that the failure

~

L

'N, t

T~ , ./

^

of the original bolt on which the NCR was written was determined to have occurred because the inspector had misread the torque value on the torquing device.

V. QUENCHING OF WELDS The remaining "open issue" which I address concerns an allegation that a weld had been quenched by direct application of

+

a water-soaked cloth. Although this item had been identified on an NCR and df 3 positioned in accordance with applicable procedures, the Board indicates that it does not understand the technical justification for *.he disposition of the NCR. Proposed Initial Decision at 44.

Rapid water quenching is a aeat treatment method utilized to harden carbon steel. Such heat treatment may af fect the micro-structure of the steel, and may. result in an increased tensile strength and hardness and a decreased ductility of the carbon steel. For these reasons, quenching of carbon steel welds and heat af fected zones is an undesirable practice and is prohibited bpsiteprocedures. The quenching which was the subject of this allegation, however, invo ved an,austenitic stainless steel. Such st; eels' do not undergo the microstructural changes carbon steels 4

undergo upo'n rapid quenching, and there is no similar metal-lurgical concern with such a cooling method. In fact, this prac-e ,

tice is quite common in welding on austenitic stainless steels.

1.0 INTRODUCTION

1.1 PURPOSE 1.1.1 The purpose of this procedure is to establish the methods by which the prime and finish coats are to be applied to the con-tainment liners and radiation areas in accordance with speci-fication, drawing, and manufacturer's requirements. This pro-cedure may also be used for coating any steel substrate inside i the reactor buildings scheduled to receive Carbo Zinc 11 primer

. and Phenoline 305 finish coat.

1.2 SCOPE 1.2.1 The scope of this procedure covers the surface preparation and coating of Unit 1 and 2 steel substrates inside the reactor buildings and radiation areas scheduled to receive protective

.j coatings.

4 1.3 GENERAL DISCUSSION l

i 1.3.1 All coating materials covered by this procedure shall be as manu-i factured by Carboline Corporation of St. Louis, Missouri. The i coating shall consist of a prime coat of Carbo Zinc 11 with a finish coat of Phenoline 305. To protect the prime coat from prolonged ex-j posure, a " seal coat" consisting of approximately one mil. of Pheno-line 305, thinned in accordance with Section 4.4.2.4, may be applied

over the prime coat. Prior to finish coating, the seal coat shall be

! solvent wiped with Phenoline thinner or Xylol. Finish coating shall j be applied when convenient prior to ccmpletion of the building or

, prior to placement of concrete, equipment. or obstructions which

! would make finish coating impossible.

In order to maintain traceability on protective coatings applied

to shop coated steel cited for installation in the Reactor l Building, these items shall be steel stamped with a unique coating code number. The code numbers shall be assigned by QC Paint and i applied by craft personnel. Upon division of materials, this j I unique number will be transferred along with all other unique identifying numbers.

4.0 PROCEDURE FOR C0ATING 4.1 PRE?ARATI0h 0F SUBSTRATES AND C0ATING MATERIA'.S

4.1.1 Surface Preparation for Primer - Final surface preparation shall i not begin unless ghe temperature of the surface to be blasted and/or

{ power tooled is 5 F above the dew point. If needed, the surface to

be primed shall then be cleaned of any heavy oil or grease deposits j -

in accordance with SSPC-SP-1-63 " Solvent Cleaning".

! Small amounts of grease or oil deposits may be removed by blast j opera tions. The surface shall then be cleaned by blast, hand or j power tool operations to achieve an equivalent of SSPC-SP10-63, a

"near white" blast cleaning. Although 1-3 mil. surface profile

is preferred, a minimum of 1 mil profile is required. After the i above surface preparation, the surfac*e to be primed shall be air blasted and/or solvent wiped to remove dust, sand or foreign

! contaminants from the surface. Air blasting shall not be performed

> where air-borne contaminants could adhere to tacky paint. Suffi-

]

cient time shall be provided to allow suspended particles to

settle before reginning primer application. If rust forms af ter surface preparation, the rusted area shall be re-cleaned before primer application. Under no case shall a blast, hand, or power

. tool cleaned surface be exposed for more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> prior to .

I hold back approximately 12" - 18" from edge of primer.

4 4.1.2 Removal of weld spatter and other minor surface imperfections j (not to exceed .031" for containment liners) - If needed, weld spatter omitted by others will be removed by Painting Personnel

~

in accordance with SSPC-SP-2 and SSPC-SP-3. If it is determined l that surface defects are severe enough to require later repair, the area to be repaired will be blocked cut and spot painted

)J at a later date. All protrusiens and peaks shall be ground l to a rounded contour.

3, 4.1.3 If coating removal is required from an area or item which has pre-4 viously been coated in accordance with this procedure, shadows or tight residue of primer which may remain in the profile of the pre-r; ,

viously prepared substrate is acceptable.

t 4.2 SURFACE PREPARATION FOR FINISH C0AT ..

i 4.2.1 Surface preparation for the finish coat shall consist of the removal,

., if needed, of any oil or grease. This shall be accomplished by the use of a manufacturer recommended cleanser or cleansing method on -

4 i areas that have been seal-coated. On areas where the Carbo Zinc 11 I primer is exposed, oil and grease will be removed by sand blasting, 3 hand, or power tool grinding, and needle scaling and then by solvent

} wiping the area prior to replacing the primer. Power tool grinding

. and needle scaling should be equivalent to a near white blast SP-10

... specification with no size limitation as long as the millage require-ments are obtained.

1 4.2.2 The ambient temperature and relative humidity shall be measured to determine the dew point temperature. Phenoline 305 finisho ccat shall be applied unless the substrate temperature is more than 5 F above the dew point.

4.3 PREPARATION OF C0ATING MATERIALS 4.3.1 Primer - The primer, Carbo Zinc 11, is packaged in a two component kit consisting of a tese and zinc filler. First the base shall be l; thoroughly mixed. Zinc filler shall then be aeded under constant

! agitation and mixed until free of lumps. Partial mixes shall be mixed

.J by weight in a proprirtion of 10 parts base to 22 parts zinc filler l~ using a suitable scale to achieve a plus or minus 2 percent accuracy.

The mixture shall then.be strained through a 30-mesh screen. Viscosity

4.4.1 Prime Coat

} 4.4.1.1 Coating material shall be applied using conventional spray equip-l ment with agitated pressure pots having a maximum hose length of 75 feet. Care must be taken to assure that air and material pressures are adjusted to compensate the additional length of

j. hose from 50' to 75' in length. The primer shall be allowed to

? become tack free before start of other construction operations

, which could create contamination problems. Any runs or sags having

a detrimental effect on the coating system shall be removed and re-i paired. The following application parameters shall also be

! followed:

• l *

1. Normaj conditions be 40 - 95 0F and 40 of ambient and surface temperature shall .

1100F respectively;0however, 0 primer may be applied within an ambient rgnge of 0 - 130 F and a sur-face temparature range of 0 - 200 F. Carbo-Zinc 11 may be thinned up to 2 quarts per gallon for application; however,

! when using higher thinning levels at or below normal tem-1 perature range, care must be taken to obtain proper film build. Above 850F it is advisable to use up to 2 quarts per gallon to minimize dry spray. In no care shall carbo-line limits be exceeded.

. 2. Humidity values vary from 10 to 95% however, coating shall not be applied to a wet or damp surface.

] '

.j

3. Thickness of prime coat shall have a minimum dry film thickness of 2 mils and a maximum of 4.5 mils. Minimum and maximum spot j test values shall be 1.5 and 5.5 mils respectively.

f 4. A double regulated pot having an adequate air volume supply shall be used, l

i j 5. As a guide, coating material may be applied using a 50% over-q lap with each pass while holding a gun 8-10 inches from the i surface. Cross hatch application is permissible.

6. Carbo Zinc 11 is sufficiently cured for topcoat wnen tne h n coating may be burnished rather than removed when rubbed

? with the flat portion of a smooth edged coin such as a

{ nickl e. (Minor amounts of zinc dust may be removed during

/ cure verification, however, a burnished surface must be achieved). Attachment 3 may be utilized as general guide-g lines for cure to topcoat time of CZ-11 above 25% relative i humidity. If required, the cure of carbo zinc II may be 1

accelerated by the use of water spray, however, a minimum i of one hour must elapse between application of coating and I water spray. Below 25% relative humidity, water curing is i recommended to obtain the desired cure. Water utilized in l

conjunction with water curing shall have a PH factor from 1 5 to 9. Application of water spray for curing purposes may-bat as often as necessary to obtain the proper cure.

]

4.4.1.2 Recoating of Carbo Zinc 11 Primer - Prior to recoating, if no major defects per section 4.4.2.9 are present, the entire primed surface to be recoated shall be wiped with clean rags moistened 3

with Carboline Thinner #33. Wiping shall continue until no i appreciable discoloration is noticed on the rags. Carbo Zinc 11 I shall then be thinned by using two quarts Carboline NO. 33 per

• l gallon mix. This will be applied to achieve a 2.0 - 4.5 mils total DFT. Only two recoats may be applied. Special attention should be given to spray application and dry film thickness when l -

using a 50% mix. The primed surface shall not be recoated until cured per section 4.4.1.1.6.

4.4.1.3 Repair of Sags and Runs - Sags or runs in excess of 5.5 mils will be adraded with an aluminum screen or sandpaper to 2.0 to 5.5 mils. Sags or runs 5.5 mils or less which show no evidence of mud-cracking will not be repaired. If coating surface is satis-factory after abrading, then finish coat may be applied; however,

d. if coating surface is unsatisfactory, blast, hand abrade or power ,

tool ' grind to near white metal is required and primer coat re-applied.

A satisfactory coating is considered one having no mud-cracking to the metal surface as visible to the unaided eye.

! kit of Phenoline 305. To aid in continuity at edges, edges may be 4 " striped" with Phenoline unthinned instead of the 50% mixture as stated above. In either " striping" or initial coating of edges, I welds, etc., time should be allotted for the coating to harden 3 sufficiently to maintain a " sealing" effect prior to continuing i

coating operations. The initial coating of edges, striping, etc., as stated above, shall be considered part of the total

), initial finish coating operation. The material shall be allowed *

{ to become tack free before any other construction operations

. .t proceed which could create contamination p'roblems by dust or 1 other foreign matter. A continuity check shall be performed in

accordance with NACE T-6F-3 Condition "C". No gross discontinuities are acceptable such as holidays, voids, skips, bubbles, and misses.

Any runs or sags having a detrimental effect on the coating system.

// April 15,1983 TXX-3655 Mr. G. L. Madsen, Chief Reactor Project Branch 1 U. S. Nuclear Regulatory Comission Office of Inspection and Enforcement 611 Ryan Plaza Drive Suite 1000 Docket Nos.: 50-445 Arlington, Texas 75012 50-446 COMANCHE PEAX STEAM ELECTRIC STATION RESPONSE TO NRC NOTICE OF VIOLATION INSPECTION REPORT NO. 83-07/04 FILE NO.: 10130

Dear Mr. Madsen:

This will serve to document our telephone conversation with T. F. Westeman on April 12, 1983, wherein we requested an extension of the due date for responding to the Notice of Violation contained in NRC Inspection Report No. 83-07/04. An extension of three working days, until April 18, 1983, was granted.

i We have reviewed your letter dated March 14, 1983 on the inspection conducted by Messrs. L. D. Gilbert and C. E. Johnson of activities authorized by NRC Construction Permits CPPR-126 and CPPR-127 for Comanche Peak, Units 1 and 2.

We have responded to the finding listed in Appendix A of that letter.

To aid in the understanding of our response, we have repeated the requirement and your firiding followed by our corrective action. We feel the enclosed infor-mation to be responsive to the Inspector's finding. If you have any questions, please advise.

Very truly yours,

i APPENDIX A fv0TICE OF VIOLATION Texas Utilities Generating Company Docket: 50-445/83-07 Comanche Peak Unit 1 Permit: CPPR-126 Based on the results of an NRC inspection conducted during the period January 27-28 and February 1-2, 1983, and in accordance with the NRC Enforcement Policy (10 CFR Part 2, Appendix C), 47 FR 9987, dated March 9, 1982, the following violation was identified.

Failure to Follow Procedure ,

Criterion V of Appendix 8 to 10 CFR Part 50 requires that activities affecting quality shall be prescribed by documented procedures of a type appropriate to the circumstances, and shall be accomplished in accordance with the procedures.

Brown & Root, Inc. , Construction Procedure CP-cpl 4 9.10, Revision 8, paragraph 3.2.4, specifies that the fit-up gap for "T" fillet joints should not exceed 1/16"; however, if the gap is in excess of 1/16", but not exceed-ing 5/32", this condition will be considered acceptable provided the leg of the fillet weld is increased by the amount of separation in excess of 1/16".

Contrary to the above, on January 28, 1983, the NRC inspector determined that Pipe Support Mark No. SW-1-102-105-Y33K had been welded with a fit-up gap of 1/4" at one end of the "T" fillet joint which attached piece 7 to piece 4.

The 1/4" fit-up gap exceeds the 5/32" maximum allowable fit-up gap require-ment of Procedure CP-CMP 9.10.

This is a Severity Level V Violation. (Supplement 11.E) (445/8307-01)

CORRECTIVE, STEPS WHICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED Corrective actions have included the following:

' 1) Identification of the procedural violation as a nonconfoming condition (NCR-51235);

2) Removal of the affected portions of the pipe support (for investi-gative reasons) and replacement with new materials;

3) Engineering evaluation of the total weld for purposes of evaluating safety consequences, if any.

[

Notice of Violation TXX-3655 As noted above, the pipe support was reworked to comply with design and procedural requirements. Engineering evaluation of the original as-built conditions revealed the following:

1) The excessive gap occurred at the toe of the skewed angle, and for a distance of six inches tcward the heel on one side and seven inches on the other. No design cregit isg taken for the weld at the toe of the angle, as it exceeds 135 (157 ). Additionally, to account for the corner effect caused by the radius of the tube steel, 2.56 inches of the weld on each side at both the toe and heel is excluded from design consideration. This results in a total eld length (for which design credit is taken) of 10.24 inches on ach side.

2) Taking no credit for the weld where gap is in excess of 5/32, and excluding 2.56 inches at both the toe and heel, the remaining weld which is within acceptance criteria is 6.8 inches on one side and 5.8 inches on the other.

3) Design calculaticns based on as-built piping loads indicate a total of 1.6 inches of fillet weld is reauired on both sides to meet structural design requirements.

In summary, had the gap conditicn not been detected, there would be no adverse results.

CORRECTIVE STEPS WHICH WILL BE TAKEN TO AVOID FURTHER VIOLATIONS Affected construction personnel will be reinstructes in the necessity for rigid compliance with design'and procedural requirenents.

DATE OF FULL COMPLIANCE Corrective actions are complete. Preventive maasures are scheduled to be completed by April 22, 1983.
