UNITS 1 and 2 PROTECTIVE COATING ALLEGATIONS TRANSMITTED BY LETTER OF MAY 18, 1984 FILE NO. 906.1
Dear Mr. Bangart:
This'1etter responds to your letters of May 18 and May 23, 1984 relative to sixty allegations about protective coating practices at Comanche Peak. To aid in an understanding of.our responses, we have repea'ted the a112ga-
' tion as stated to us in your letter of May 18, 1984 followed by our ~ response in the format requested by your letter of May 23, 1984.
Our responses were developed based on technical knowledge, kncwledge of actual jobsite conditions, review of existing documentation found to be analogous to certain of the allegations, and where appropriate, inter-views with cognizant QC personnel. As you will note, supporting docu-
^
mentation is included with certain responses as a means of shortening the length of the response. We trust you will find the enclosed infomation helpful in expediting < closure of these issues. Please advise if you require further infoma-l, tion. Sint.erely yours, r , l e408220412 e40007 PDR ADOCK 05000445 PDR G LFF: pew Enclosures cc: Mr. Thomas A.

,;- Al' legation No. 1 Paragraph 4.3.1.2 o'f Procedure Number CCP-40 states " Imperial coatings may be applied in the following sequential order: !11S/1201/11S/1201 or 11S/1201/11/1201." Imperial letter dated May 8, 1978, VBR-7697 to dr. Kelly
-W111 b==, second paragraph, states: "Although the resultant systems
#11S/1201/115/1201 or #11S/1201/11/1201 have not been qualification tested, chare is no reason to believe that they are not viable systems." Thus these two
}
systems have not been DBA qualified. Evaluation of Validity This allegation is correct, but is not significant because this combination of coatings occurs in limited areas. Nutec 11 or 11S and Nutec 1201 are applied to existing 11S/1201 only during a touch-up repair or during interface with previously applied adjacent coatings. This overlapping is necessary in order to achieve a smooth transition with the previously applied adjacent coatings. Due to the limited area of coatings involved in overlapping systems as a result of applications adjacent to previously coated surfaces and/or coating repairs, this issue has never been considered to be significant enough to warrant special consideration such as DBA qualification. DBA data is unavailable for 11S/1201/11/1201 and 11S/1201/11S/1201 - the two combinations specified in the allegation. Imperial has, however, conducted i E1cometer adhesion tests for the above systems at both high and low film thicknesses and all systems passed. (See Imperial's Report No. 759, attached). Additionally, Imperial has developed satisfactory irradiation and DBA data for systems similar to these specified in this allegation (see response to Allegation No. 12). 6

Introduction:
Following the installation of the 11S/1201 concrete coating system, it sometians becomes necessary to repair damaged areas or fill holidays in the original system. Also separate applications ' sometimes result in overlap of the newly applied coatings to : adjacent, aged systems. The result is the application of Nutec 115 or 11 over previously applied ar.d cured 1201 topcoat. The purpose of this adhesion test is to demonstrate the validity of this practice. procedures: Concrete blocks, measuring 2x4x2" were coated with the following
'~
systems:
?
A] Nutec 11S (10 mils)
. Nutec 1201 (3 mils) ,
Nutec 115 (10 mils) Nutec 1201 (3 mils) 3] Nutec 115 (35 mils) Nutec 1201 (16 mils) Nutsc 115 (35 mils)
. Nutec 1201 (16 mils)
C] Nutec 115 (10 mils)
, Nucec 1201 (3 mils)
J Nutec 11 (3 mils)

DT Nutec IIS (35 mils) Nutec 1201 (16 mils) Nutec 11 (20 mils) Nutec 1201,(16 mils) - The dry film thicknesses applied were selected to envelope the , thickness range actually applied at nuclear jobaites. For
- application and curing details refer to the attached panel -
preparation. sheets. Six adhesion tests were conducted on each system (two testa per concrete block) using an E1cometer adhesion tester. e e t' e

sav , + . o T22-4201 06/22/94 ) I Allegation No. 2 Specific sequencing of coatings systems not required. For example, NRC (sic) No. C83-01752 dated 06/23/83, Disposition section, first paragraph, states: " Table A2 in Appendix A of AS 31 specifies acceptable coating systems, i.e. , primer and final coat product identification and vendors." Then goes on to say that full sequencing is not identified. "This table does not identify full system sequencing or application parameters." Does a system's sequencing change for a repair! Why? Has the repair sequence been DBA qualified? Evaluation of Validity The allegatica is not valid. Specification 2323-AS-31 Appendix A, Table A-2 (attached) does require specific primer /copcoat sequencing. Not a 3 to the table .
- states "It is essential that coating systems be used only as specified above, unless an alternate system is proposed by a coating asuufacturer and subsequently approved by the Engineer."
The specification limits application paraseters to " manufacturer's latest application instructions," which includes field touch-up and repair. : The manufacturer's data sheets, application instructions, and letters clarifying
. procedures were the basis for the application procedures issued for use at CPSES.
These procedures described allowable overlap during touch-up or repair and sequence of coating application. As indicated in our response to Allegation No. 1, the coating system sequence on an area which has been repaired may differ from the coating system sequence which was subjected to DBA qualification. However, due to the limited area of coatings involved in overlapping systems as a result of coating repairs, this issue has never been considered to be significant enough to warrant special consideration
- such as DBA qualification.

. DCA. No.12.374 Rev.1. allows inorganic sine primer (Carboline C2-11 ?) to be top coated by Imperial 1201. Mas this system been DBA gualified? ,
~ . Evaluation of Validity I The CE-11/Nutec 1201 system has been DBA qualified. (See attached test report indicating DBA qualification for this system). It should also be noted that DCA No. 12.374. Rev. 1 deals only with the presence of C2-11/Nutec 1201 on Richmond Inserts that are embedded in concrete. Due to the size and configuration of j these areas and difficulties with application details, these coatings have been classified as indeterminate and have been placed on the Protective Coatings
- Essept Log (see entry number 30 on Protective Coatings Exempt Log attached).

Allegation No. 5 Procedure No. CCP-30A, Rev. 2, page 2 of 13, paragraph 1.3.1 allows the application of Carboline 305 over the primer Dimercoce 6 by Amaron. Has this system been DBA qualified? Evaluation of Validity We assume the term " Carboline 305" used in the allegation refers to Phenoline 305 manufactured by Carboline. A coating system of Carboline's Phenoline 305 over Amaron's Dimatcote 6 primer has.been specifically qualified for DBA.

06/22/84 I Allegation No. 6 Procedure No. CCP-40 Rev. 5, page 5 of 13, paragraph 4.1.1.3 states: " Repair of embedded foreign objects such as nails, rebar chairs, bolts, wood or' plastic shall be repaired per the following guidelines before applicatien of Nutsch 115 surfacer." Have these systems been DBA qualified? Evaluation of Validity The application of Nutec 11S over repaired embedded objects has not been DBA qualified, but this fact is without safety significance. The surface area of foreign objects. embedded in concrete is negligible in proportion to the total area of any given concrete surface receiving coatings. m 4 In any event there is substantial evidence that objects such as nails, rebar chairs, bolts, wood or plastic embedded in concrete does'not affect the adhesion characteristics of Nutec 11S. .
- 1. Observations made in Imperial's labs over the years while preparing concrete coupons for DBA teses. The concrete blocks were formed in plywood, lattice like forms which occasionally transferred wood particles and splinters to the concrete surface. No failures were ever :
attributed to the wood in the concrete. Refer to attached imperial letter dated March 8,1984,
Subject:
Wood Splinters in Concrete.
- 2. Qualitative tests conducted by Imperial. These tests found that Nutec 11S adhered to both rebar chairs (rubber and polyethylene). Refer to attached Imperial's letter dated March 8, 1984,
Subject:
Rebar Chairs.
- 3. E1cometer Adhesion tests performed at Comanche Peak. Results averaged well above the required minimum of 200 psi. Refer to attached Interoffice Memo dated June 19, 1978,
Subject:

SUBJECT:
Wood Splinters in Concrete
Dear Jerry:
Attached is a copy of my letter of April 19, 1978 dealing with wood " splinters" !. embedded in concrete. I still concur with the opinion expressed in th'a 1978 letter based on the following:
- 1. Good sound painting practices. The surface preparation that was recommended is sufficient to remove loose particles. All that remains is intact, embedded
{g meterial.
- 2. Visual inspection of embeddeli vood in concrete surfaces at Comanche Peak be-fore and after surface preparation.
- 3. The small amount of surface area involved. The embedded material in question is not large pieces of wood, rather small hair-like splinters. The amount of wood in contact with the Nutec 11S surfacer is =4n4=1 compared with the con-crate surrounding it.
4 Observations made in.che lab over the years while preparing concrete coupons
- for DBA tests. Imperial's concrete blocks were formed in plywood, lattice-like forms which occasionally transferred wood particles and splinters to the concrete surface. No failures were ever attributed to wood in the concrete.
Jerry, if you have any questions please don't hesitate to call me. Sincerely,
- Jerry.irnold cr:: Jurry Firtal (Ebasco-NY)

SUBJECT:
Rebar Chairs
Dear Jerry:
~
My recowenandation for handling rebar chairs in the past has been to use a mechanical tool such as a 3-M Roto Peen to cut the protruding tips flush with the concret sur-face while at the same time imparting a profile to insure adharance of the Nutec 115. r.f.Several years ago I conducted some qualitative tests on rebar chairs for another job i.
- cita. I applied 11S to two types of rebar e hairs; rubber and polyethylene. I found p that the Nucec 113 adhered better to the rubber tips and Nutec 11S would adhere to polyethylene chairs with a rough profile. Because of the gecmetry of the rebar chairs E1cometer Adhesion tests are not feasible. I believe that jobsite adhesion tests woul'd substantiate my findings. * '

s . l On the other hand no defects were observed on the 115 surfacer ever ji abrasive blasted steel. Mixed results were cbtained en 11S/1201 specimens
; ; which had been abrasive blasted. Two of four faces locked excellents ;, . wheraas the two remaining faces exhibited some blistering.
P
$ .; Of the eight 11S/ abrasive blasted steel interfaces, five exhibited no defects ?. and one contained very few #6 blisters (75% passing) . Of the two faces which Oak Ridge National Laboratcries reported as #2M, one appears marginal.

k.i CONCLUSIONS:
? _ ;- Based on the test results, application of Nutec , ;;. 115 is not recommended (for surfaces greater than e ~,
two square inches) over clean-n'-strip prepared j steel in containment areas which would be exposed to the temperature and pressure conditions observed in this test. Application of Nutec llS is reccmmended for over-lap on steel imbeds (maximum 2 inches overlap) and over imbedded steel objects (up to six square inches),
' which have been abrasive blasted or prepared with power tools which impart a surface profile (i.e.,
roto peen). Of the eight abrasive blasted faces coated with
-. Nutec llS, five exhibited no defects and one contained only very few #6 size blisters. Oak Ridge also
> reported one face of panel 7829 (rear) as having
#2 medium blisters. Imperial evaluated the panels thoroughly and believes that ORNL mistakenly eval-uated the same face (front side) twice. Imperial
- has reevaluated the rear of panel 7829 to only few
__, #4 blisters. The front side of panel 7829 was border-(;, line. i. i,, . r
-Therefore, of the eight abrasive blasted faces tested, Imperial finds that seven comply with the ANSI N101.2 acceptance criteria (no larger than #4 few blisters) and the eight face is borderline. This amounts to an 87.5% success rate.
~
NOTE: Technical reports #353-80 and #413-80 relate E1cometer l:^ ' adhesion test data of Nutec 11S over abrasive blasted and power tool cleaned steel surfaces. These reports are reccmmended for review, especially for Service Level II and Balance of Plant service, when DBA testing is not required, that is, where the coating system will not be subjected to Loss of Coolant Accident conditions. lI li l! ** N

- New Orleans', LA Oak Ridge National Laboratory ;
.Date: 11/13/80 Q . .- Report of Irradiation and DBA Testing ,
(~ The irradiation and design basis accident (DBA) tests are conducted. respectively, in accordance with Bechtel Corp. Secnd:rd Specificction Coat-3 ings for NucIscr Pouer PIcnes,. specs. CP-951 and CP-956 (or with modifi-
.i cations.as' noted in Table 2, DBA test conditions). The tests are designed
- f. to meet the specifications set in both A.N.S.I. report N 101.2-1972, Pro-
- i. .ective Coa:ings (Ecints) for Light Water Nuclear Reac*ar Cantair:nent f Facili:les, and N 5.12-1974, Prctactive Coatings (Pain:a) for the Nuclear
< Industry. The DBA test spray solution and the test conditions are listed
.! in Tables 1 and 2. After both the DBA and the irradiation tests, the
; coatings are examined for signs of chalking, blistering, cracking, peeling, .
delamination, and flaking, according to ASTM standards where applicable. All test panels a.re ,returney to the coating' manufacturer. j . The irradiation tests are run using a spent fuel assembly, removed
.: from the High-Flux Isotope Reactor (HFIR) at ORNL, as the source of radia-
~h
. tion. These_ fuel assemblies are stored under 20 feet of demineralized
, water. The fuel .is 93:; enriched U235 .as U 0s 3 ccmbined with aluminum. -. :
The spent fuel assemblies are removed afte'r each 23-megawatt day period. Irradiation is done using the gamma energy from the accumulated mixed fission products. This more readily simulates conditions around a reactor than does a esbalt' source. Also,'the higher gamma activity affords
- shorter irradia, tion time to achieve accumuTated , doses. The dose rate four .
days after removal of a fuel assembly from the rea'ctor is 1 x los rads /hr. The fuel assembly is 20 inches high.i,-d.j20-fbotji gggi/,2Sinch diameter pipe, with one end capped, is used for the air irradiation tests. The capped end is lowered into the four-inch opening of the center of the fuel assembly. The open end, above the water level, is cove: ed with an "0" ring sealed flange to which is attached a steel cable and an air ouflet hose. The air inlet is located at the bottcm of the pipe. The test speci-mens are connected to the bottom of the cable and lowered into the radiation field. Also at the center of the fuef assembly is a stainless steel clad j'
.s cadmium tube used as a neutron absorber. This, prevents contamination of the test specimens by induced radiation.t -

'A11eastion No. 7 NCR No. C83-01986 discusses the cracking and flaking of concrete coatings systems (NUTEC 11, 115, 1201). The disposition section of this NCR states "crading of coatings is due to excessive stresses in the coating during drying and curing."
The allegation is that repairing these cracks will not remedy the condition which caused the cracks. n Evaluation of Validity The allegation as stated is true. The preventive measure to preclude recurrence of this condition is the proper application of the coating with emphasis on control of film thickness (see manufacturer's application bulletin attached). Raquirements for control of the thickness of concrete coatings are included in procedures QI-QP-11.4-10, QI-QP-11.4-27 and CCP-40. If the coating is
~
inadvertently applied too thick and cracks, the inspection process notes the i problem and corrective action, i.e., rework of affected area, is taken. Safety Sianificance None Generic Isolications on other Systems or Contractors i Not applicable

NUTEC SYSTEM - FII.M THICKNESS CCNTROI.S r i.
Dear Customer:
}.
This application bulletin has been prepared as a reminder that stress cracking
- is possible within the Nutec 11S system if application parameters, specifically;
; film thickness, copcoat times, and thinning are not controlled.' Cracking. '
observad to date, has been restricted to floor areas where film thicknesses
; have dramatically exceeded the reconenended tolerances. The problem is inherently difficult to detect because of the problems of accurately measuring the applied thickness of a coating on concrete. Routine wet film or dry film measuring ;, cachniques do not work on concrete. On valls,the problem is not acute because .
the coating vill slung or sag, revealing the excess very readily. , A. Two sites had' experienced minor stress cracks on floors, especially at
.j ,m,y' the wall floor interface where the cornors were covered with Nutec 115.
;b Both sites recognized the lack of control on film thickness and took
- steps to monitor film thickness, recost times, and thinning. No j,
further occurrences have been reported.
- Numerous sites have used the Nutoc system and no cases of stress cracking have been reported to Imperial from Comanche Peak.. South Texas Project,
; Riverbend, WPPS) 1. WPPSS 3. Hopeereek, Millstone, Beaver Valler, and Shenton liarris. In addition, no cracking has been reported from the
; many non nuclear applications in which Nutec 11S has been applied.
-I : B. The following is a review of application conditions which appear in Imperial's application procedures distributed to each nuclear jobsite prior to start up apinting with Nutec system.
*l

2 .- Patching Voids '
Nutec 115 has been recommended for patching voida below the plane of the 1 .Qi.<.1 surf ace (i.e., busholes) measuring \" in depth and diameter. Larger
;, voids up to 1" inch depth and 2" in diameter may be filled, but usually require at least two passes to prevent sagging. In any case, ptior to copcoating, these void areas should be cured to the extent that a fingernail j impression can not be left in the surface.
Note: Nutec 11S is not recommended for leveling out undulating or very rough concrete. In cases where concrete has a very rough profile due to blasting or bush hammering, the film thickness restrictions outlined above must be observed. l
.. 3. Topeone Times
.j Attached are a table and graphs which outline the cure times recommended j' for various film thicknesses. Thicknesses above 35 mils require additional Stresa cracks may occur within the Nutec 115 if the topcoat 14
; cure tius.
- applied before the Nutec 115 his an opportunity to suf ficiently* cure through.
Application of the topcoat, before the recommended cure time has been achieved, may entrap solvent within the film, especially if the 115 has been applied
- at thicknesses above 35 mils. One can easily appreciate that a combination of a high film thicknees and inadequate cure followed by the subsequent
,' " swell" caused by introduction of the solvents in the topcoat must subsequently
. be replaced by shrinkage uhich may result in stress cracks.
'N
' O 4. Thinning
! Haximum thinning with DL-54 solvent is 51 by volume.
j In summary, the cracking problema can be avoided by following the 1special
- application instructions, for the Nutec concrete coating system, which are present at all jobsites. Particular attention should be paid to the application
<, parameters outlined above. On those projecta uhere the parameters listed above are carefully controlled, there is .no probles with cracking.

l Allegation No. 8 4 , Paragraph 4.1.3 of Procedure Number CCF-30. Rev. 11, states: " .. shadows or . tight residue of primer which may remain in the profile of the previously 4 prepared substrate is acceptable." The allegation questions the integrity of an
~
inorganic sinc primer which has been applied over a steel substrate with metallic sine residue in the profile of the steel. The concern is th'at there will be coating adhesion problems, and that the zinc is isolated from the carbon steel substrate; thus the necessary galvanic action will fail to occur. Evaluation of Validity This allegation is without technical significance. Multi coats of inorganic zine primers have basa DBA qualified. (See Carboline Testing Project Report 01978.1 Final Report, attached, and response to Allegation No. 9). The DBA tests for CZ-11/CZ-11 systems indicated no failures in delmaination, peeling, cracking or blistering. There is no question as to the ability of CZ-11 to adhere to a steel substrate, and the attached DBA test results indicate that CZ-11 will adhere acceptably to previously applied CZ-11. Therefore, the concern relative to CZ-11 adhering to a steel substrate with tight residue of primer is unwarranted. 9 Safety Sianificance None j Generic Implications on Other Systems or Contractors Not Applicable 4 y e- . . _ -- ,.. _.m. --- -. - _ . - . . .__...w.,.my_,._. _ _ - , . - - . - -..r..,_._.,me,-

- ' Allegation No. 9 It.is alleged that three coats of inorganic zine primer have been applied at Comanche Peak to obtain the required dry film thickness. Paragraph 3.2.4 of Instruction Number QI-QP-11.4.5, Rev. 27, states: "Only two (2) overcoate shall be applied." It is alleged that this system would lack chemical attraction or
. intercoat adhesion with itself. Is this three coat primer system qualified, for-eneple for environmental (irradiation) conditions and DBA conditions, under ANSI N101.2-19727 This is another example of the coatings systems not being l qualified. .
Evaluation of Validity
- It should be noted that the application of three coats of inorganic zine primer is fully consistent with QI-QP-11.4-5. An " overcoat" of primer is a primer coat applied over an existing coat of primer; "two overcoats" would amount to a 'tal of three coats of primer.
CCP-30 and CCP-30A are the two application procedures used at CPSES for Carboline and Amaron. inorganic zine primers, respectively. Both systems described in the two procedures are DBA qualified in accordance with ANSI N101.2 and are in accordance with the manufacturer's recommendations. Multi coats of inorganic zine have been specifically qualified by both Carboline and Amaron. (See attached Carboline Testing Project 01978.1 and 02182, Ameron Report TRC-089-03, and response to Allegation No. 8). 4 Safety Signific.ance 7 None Generic Implications on Other Systems or Contractors t 4 Not applica'ble
