9/14/83 REPORT OF IPRADIATION AND OBA TESTING The irradiation test is conducted in accordance with Bechtel Corporation specifications CP-951 in Standard S)ecification Coatings for Nuclear Power Plants.
The design basis accident (DBA) test is performed in accordance with ASTM D3911-80.
The tests are designed to meet specift-cations set in both ANSI report N 101.2-1972, Protective Coatings (Paints) for Light Water Nuclear Reactor Containment Facilities, and N 5.12-1974 Protective Coatings (Paints) for the Nuclear Industry.
The DRA test spray solution and the test conditions are listed in Tables 1 and 2.
After both the DBA and irradiation tests, coatings are examined for signs of chalking, blistering, cracking, peeling, delamination, and flaking, according to ASTM standards where applicable.
All test panels are returned to the coating manufacturer.
The irradiation tests are run using a spent fuel asserbly, removed fron the High-Flux Isotope Reactor at ORNL, as the source of radiation.
These fuel assemblies are stored under 20 ft of domineralized water.
The fuel is 93% enriched U-235 as U 03 8 cor.bined with aluminuri.
The spent, fuel as-semblies are removed after each 23-mecawatt-day period.
Irradiation is done using the gamma energy from accumulated mixed fission products.
This more readily simulates conditions around a reactor than does a cobalt source.
(
Also, the higher gamna activity affords shorser irradiation time to achieve accumulated doses. The do from the reactor is 1 x 10ge rate four days after removal of a fuel assembly rad /h.
The fuel assembly is 20 in. high.
A 20-f t-long, 3-1/2-in.-diameter pipe, with one end capped, 15. used for air irradiation tests, The capped end is lowered into a 4-in. opening at the center of the fuel assembly. The open end, above water level, is covered with an 0-ring-sealed flange to which is attached a steel cable and an air outlet hose.
The air infet is located at the bottom of the pipe.
Test specimens are connected to the bottom of the cable and lowered into the radiation field.
Also at the center of the fuel assembly is a stainless steel-clad cadmiun tube use as a neutron absorber.
This prevents contamination of the test specimens by induced radiation.

COMMONWEALTH EDISON COMPANY l
BRAIDWOOD STATION CARBO ZINC 11/PHENOLINE 305 CONTAINMENT LINER COATING SYSTEM The containment liner coating system, as specified, consists of a white metal blast cleaned surface, an application of 3 to 6 mils dry film thickness (DFT). of Carbo Zinc 11 primer and an application of 4 to 6 mils (DFT) of Phenoline 305 finish coat.
An initial application of Carbo Zinc 11 was. completed in the shop prior to shipment.to the site.
This initial application consisted of 3 to 6 mils.(DFT) on the interior portion of the liner. panel.
Strips adjacent to the edges of the panels were left uncoated to facilitate seam welding during installation.
The liner panels had become weathered and aged.
Therefore, prior to application of the finish coat, the entire. liner was cleaned by light sand blasting which reduced the Carbo Zinc 11 DFT by approximately 50%.
The weld seams were sand blasted to white metal.
A field application of Carbo Zinc 11'was then made in order to coat the seam areas and to restore the Carbo. Zinc-11 in the panel interior to the specified 3 to 6 mils.
The Phenoline 305 finish coat was.then applied from the foundation (Elevation 377) to 10' above the-pool floor (Elevation 436) thereby completing the containment liner coating system.
During a review of coating records, an inspector identified a concern regarding the interpretation of the coating manufacturer's application instruction relative.to the field application of
' Carbo Zinc 11.
Note (a) of the instructions recommends that to recoat Carbo Zinc 11 - thin 50%.
The field application of Carbo Zinc 11 was performed at normal thinning of 0% to 12%,
as described in the manufacturer's application instruction.
Midway Industrial Contractor, Inc. Nonconformaace Reports (NCR) 31 and 32 and Commonwealth Edison Company NCR 7.t8 were written to address this concern.
Corrective action for this NCR was developed in consultation with the coating manufacturer (Carboline Company).
It was the judgment of Carboline Company, Sargent & Lundy, and Commonwealth Edison Company that the. Carbo Zinc 11 had been applied in a satis-factory manner; however, in order to assure that the two applications of Carbo Zine 11 behaved monolithically, adhesion characteristics were investigated.
1
~
Initial adhesion tests were performed on the in-place liner coating.
The tests.were located at two seams and corresponding adjacent interior panels.
The adhesion values at the seams were equivalent to those exhibited by the corresponding adjacent panels.
The Carbo Zinc 11 at the seams was applied in a single application while that in the interior of the panel was applied in two applications.
The equivalent adhesion values between the seams and the interior indicates that the two applications of Carbo Zinc 11 are monolithic.
Subsequent adhesion tests were performed to investigate the relation-ship between adhesion characteristics and thinning ratios when recoating Carbo Zinc 11.
Steel plate with a prime coat of Carbo Zine 11 was selected from the site laydown which had weathered over 2 years.
The plate was cleaned by lightly sand blasting, as the containment liner had been.
A different color Carbo Zinc 11 was then applied at thinning ratios of 0%, 15%, 30%, and 50%
over four different areas of the plate.
Fifteen adhesion tests were performed on each of the four areas.
In all cases, the test specimens failed in cohesion from within one of the coats or through both coats.
No case failed in adhesion debonding between the two coats.
In fact, the area of the plate recoated at 0% thinning exhibited higher adhesion values.
These tests show that Carbo Zinc 11 behaves monolithically, regardless of the thinning ratio used for the second application.
Carboline Company has reviewed the application method and adhesion test results.
They have concluded that the 50% thinning recommen-dation provided in their application instruction does not apply, but rather the normal thinning provisions of their instructions do apply to the conditions of the Braidwood Station containment liner.
The current Design Basis Accident (DBA) qualification tests remain applicable.
Carboline Company has clarified their position with respect to the thinning requirements in their application instruction.
The 50% thinning is recommended for applications of a thin recoat
'(1 mil) to facilitate the applicator.
A thin recoat may be necessary to build a coating up to specified DFT and is generally applied over freshly cured Carbo Zinc 11.
The thinner does not become a part of the final coating system as it evaporates during curing.
When restoring a coating with a 3 mils DFT application or applying an initial coat over clean steel, as was the case at Braidwood S tation, normal thinning ratios of 0% to 12% are recommended.
The applicable standards for containment coating work are ANSI 5.12, Protective Coatings for Nuclear Industry, and ANSI 101.2, Protective Coatings for Light Water Nuclear Reactor Facilities.
ANSI 5.12 is a general standard created to standardize methods, including adhesion tests, for evaluating safety-related and selecting coating systems for the nuclear industry.
ANS I 101.2, is a standard created specifically to evaluate coating system behavior in a containment environment, including DBA' conditions.
The test requirements of the two standards are unrelated.
2
l The_ adhesion characteristics exhibited by the tests undertaken indicate that the two applications of Carbo Zinc 11 acts as a monolithic coat.
Therefore, the coating system _as specified, a finish coat of Phenoline 305 over a prime coat of Carbo Zinc 11, was maintained.
The original DBA tests which qualified the specified coating system remain applicable.
Additional DBA test data is available which details the performance of similar coating systems applied with a variety of procedures.
All these systems performed acceptably under DBA conditions.
Relative DBA tests are as follows:
1.
Oak Ridge National Laboratory Test #01269 CZ-ll/Phenoline 305 Original qualifying test (The coating systems tested consist of a white metal sand blast surface coat of CZ-ll at normal thinning and a finish coat of Phenoline 305.)
2.
Oak Ridge National Laboratory Test #02182 Single and multiple coats Carbo Zinc 11 at equal DFT (The coating systems tested consist of single coats of CZ-11 at normal thinning and multiple coats of CZ-ll with second and third applications made at 50% thinning over fresh cured CZ-11.)
3.
Carboline Company Test #01978.1 Single and multiple coats Carbo Zinc 11 at equal DFT (The coating systems tested consist of single coats of CZ-11 at normal thinning and multiple coats of CZ-11 with second and third applications made at 50% thinning over fresh cured CZ-11.)
4.
Carboline Company Test SR 57 CZ-ll/CZ-ll/Phenoline 305 with various surf ace preparations-(The coating aystems tested consisted of an initial aged coat of CZ-11 which was then cleared with various scrubbing agents, a second application of CZ-ll at normal thinning and at finish coat of Phenoline 305.
Note:
documentation regarding details of application is not available.)
5.
Oak Ridge National Laboratory Test #A9675, A8-15-3 CZ-ll/SP-7/CZ-11/191HB at 12.5% and 30% thinning.
(The coating system tested consisted of an initial coat of CZ-ll which was then cleaned by lightly sand blasting, a second application of CZ-11 at 12.5% thinning and 30%
thinning and a finish coat of 191HB.
Phenoline 305 and 191HB are similar Carboline finish products.)
3
The breadth of data obtained from testing demo.nstrates that the note in the manufacturer's application instruction was not applicable to the Braidwood Station containment liner coating system.
The containment liner coating system was applied consistent with the manufacturer's application instruction and remains as originally specified.
The current DBA qualification' test remains applicable.

SUMMARY
REPORT: SR-57 Final Report PANEL PREPARATION:
Weathering - All test coupons were primed with either Carbo Zinc 11 or Carbo Weld 11 and allowed to wrather for 2 1/2 months on the Gulf Coast. The weathering racks are all at a 45' angle and situated so as to obtain the maximum amount of Ultraviolet (UV) sunlight available.
Side 1: Weathering and U.V. - This is the area of the panel facing the sun, receiving both a moist or vet exposure and an alternate drying of the surface by the intense sunlight.
Side 2: Weathering - This side of the coupon is away from the sun.
It receives a moist or wet exposure, but does not experience either the direct U.V. sunlight or the washing (rinsing) effect produced by rain.
Results for each coupon are differentiated as to the side receiving the intense U.V. sunlight and the side facing away from the sun.
PERFORMANCE EVALUATION:
Due to the nature of this screening series, edge effects were not considered in performance eva?uation. Please note that standard 2" x 5" x 1/8" steel panels were ' employed, and not the 2" x 5" x 1/4" with rounded corners and edges steel panels that are normally used in LOCA testing. Please refer to " Discussion of Results".
GRADING PROCEDURE:
The test coupons were evaluated for performance in the following areas:
1.

SUMMARY
REPORT': SR-57 Final Report DISCUSSION OF RESULTS:
Edge failure was ignored for all performance evluations in this project. This was necessary since the test coupon was one-half the thickness of that specified for LOCA testing, and each side of a test coupon was being evaluated independently.
Edge failure, if it did occur, would be most likely due to the thin, sharp edge and it would be inaccurate to assign the failure to the coating on either or both sides.
