~

i After 1 year Simulated Outside Exposure

Purpose:

To evaluate the recoatability of Nutcc 1201 over the weathered 560/1201 To simulate 1 year outside exposure by subjecting panels to system.

250 hours0.00289 days <br />0.0694 hours <br />4.133598e-4 weeks <br />9.5125e-5 months <br /> of exposure in an Atlas Twin Arc Weather-o-meter.

Methods::

)

Two ASTM A36 carbon steel panels, nos. 48 and 65, measuring 2"x4"xl/4" i

were sandblasted per SSPC-SP-10 with a profile between 1570 and 2570 as read on a Keane-Tator Profile Comparator Disc. Tne panels were coated with Durazinc 560. steel primer and Nutec 1201 epoxy topcoat, allowing for proper ct:re times between coats. Application and curing procedures ara outlined below. The test specimens were then weathered j

for 250 hours0.00289 days <br />0.0694 hours <br />4.133598e-4 weeks <br />9.5125e-5 months <br />. Following removal from the weahter-o-meter, panel no. 48 was solvent wiped and panel no. 65 was cleaned with a dry cloth.

l Both panels were then topcoated with Nutec 1201 cured and sent to UNO for DBA testing at the Houston Lighting & Power curve.

Topcostability of Durazinc 560 Primer q

Purpose:

To determine if extensive weathering of the Durazinc 560 primer has any diverse effects on topcoating with Nutec #1201. To simulate 2 years out-side exposure by subjecting panels to 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> of exposure in an Atlas Weather-o-meter.

Methods:'

Two ASTM A36 carbon steel paneIs, No. 7I & 72, measuring 2" x 4" x 1/4" were sandblasted per SSPC-.SP-10 with a curface profile between IS70 and 2S70 as read on a Keane-Tator Profile Comparator Disc. The panels were primed with Durazinc 560 allowed to cure three days at ambient l

temperature and then placed in an Atlas Weatherometer for 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br />.

j Upon removal from the weahter-o-meter panel 71 was solvent cleaned (DL 6A) and panel 72 was wiped with a dry cloth. Both specimens were topcoated with Nutec #1201, cured, and sent to Coastal Sciences for DBA testing at the Houston L,ighting & Power Curve.

Topcoatability of 560/1201 Mist Coat After Simulated One Year Outside Exposure 17, j

Purpose:

To study the coatability of Nutec 1201 epoxy topcoat over weathered 560 steel primer /Nutec 1201 mist coat. To simulate one year out-side exposure by subjecting panels to 250 hours0.00289 days <br />0.0694 hours <br />4.133598e-4 weeks <br />9.5125e-5 months <br /> in an Atlas Twin

~

Arc Weather-o-meter.

J Method:

J Two ASTM A36 carbon steel panels Nos. 45 & 46, measuring 2" x 4" x 1/4" were sandblasted per SSPC - SP - 10 with an anchor profile between i

i IS70 and 2S70 as read on a Keane-Tator Profile Comparator Disc.

I The panels were coated with Durazinc 560 primer, cured for 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> and placed in the weatherometer for 250 hours0.00289 days <br />0.0694 hours <br />4.133598e-4 weeks <br />9.5125e-5 months <br />. Upon removal, panel no. 45 was solvent cleaned and panel no. 46 was wiped with a dry cloth.

Both test specimens were then topcoated with Nutec 1201, cured for 7 days at room temperature, and sent to the University of New Orleans for DBA testing at the Houston Lighting & Power curve.

Page 1 O~ SCC?!:

The purpose of this test was to evaluate the performance of the Nutec concrete coating system with multicoats and high film U

thicknesses of Nutec 1201 topcoat.

1 BACKGROUND:

In many cases, additional coats of Nutec 1101 are applied to the original Nutec con' crete coating system. Such instances are:

1.

' Film building to achieve designated mininnd thickness requirements; 2.

Repair of pinholes; 3.

Repair of damaged areas, with resultant overlap; 4

Overlapping adjacent previously coated areas; 5.' Recoating' for aesthetics (usually a fresh coat is applied

}'

to the system just prior to the contractor' releasing the area to the client).

When the 11S/ll/1201' system'is recoated there is the potential for exceeding the specified maximum dry film thickness of 12 mils for Nutec 1201. This test was designed to evaluate the higher film thicknesses of 1201 both in a single coat application and in a two coat application.

, SU!O'.ARY:

Four specimens coated with 115/7.1/1201/1201 were submitted to OakRidgeNationalLaboratorgesforradiatientolerancetesting at exposure levels of 3 x 10 and 1 x 109 rads, and design basis accident testing per the pressurized' water reactor (PWR) parameters of 285'T and 48 PSI. Due to equipment malfunctions, the actual arriman temperature and pressure experienced was 340*F and 70 PSI respectively. The results comply with the acceptance criteria of ANSI N101.2 for DBA testing.

PROCEDURI:

Four concrete specimens were coated with the Nutec llS/Nutec 11/

Nutec 1201 system as described in the attached panel preparation sheets.

O Radiation Tolerance /DBA Results 11S/11/1201/1201 Page 2 FROCEDURE (Con't):

Coupons A79 and A81 were first topcoated with the 113/11/1201 system, weathered in an Atlas Weather-o-meter for 300 hours0.00347 days <br />0.0833 hours <br />4.960317e-4 weeks <br />1.1415e-4 months <br />, used in an Elcometer adhesion test, repaired, and then re-topcoated with Nutec 1201.

0 All spec ns were submitted to ORNL for irradiation at 3 x 10 and 1 x 10 rads and then design basis accident tested. The critical p~ortion of the DBA test (first 28 hours3.240741e-4 days <br />0.00778 hours <br />4.62963e-5 weeks <br />1.0654e-5 months <br />) was performed in the autoclave; the remaining 10 days was conducted in a constant temperature and pressure chamber with 100% relative humidity.

RESULTS:

l 3

See attached ORNL results and result su= mary.

j CONCLUSIONS:

The results comply with the requirements of ANSI N5.12 (radiation

?'

tolerance) and ANSI N101.2 (DBA), indicating that the higher i

film thickness of 1201 *aad ne adverse effects on the performance of the Nutec system.

It should be noted that higher film thicknesses of 1201 may result in a slower evaporation rate (of solvent) and a correspondingly longer full cure time.

j REPORT OF IRRADIATION AND DBA TESTING The irradiation and design basis accident (DBA) tests are conducted, respectively, in accordance with Bechtel Corporation specifications CP-951 and CP-956 in Sta.-dard S;:ecification Coatinos for Noclear Power Plants (or with modifications as notec in TaDle 2, DBA test cono1tions). Ine tests are designed to meet specifications set in both ANSI report N 101.2-1972, Protective Coatings (Paints) fo.- Licht Water Nuclear Reactor Containment Facilities, and h 5.12-1974, Protective Coatings (Paints) for the Nuclear

)

Incustry. The DBA test spray solution anc tne test concitions are listeo in Taoies 1 and 2.

After both the DBA c9d irradiation tests, coatings are examined for signs of chalking, blistering, cracking, peeling, delamination, and flaking, accordirg to ASTM standards where applicable.

All test panels are returned to the coating manuf acturer.

1 The irradiation tests are run using a s ent fue1 assembly, removed from the Higi-Flux Isotope Reactor at ORNL, 'as the source of radiation.

These fuel assemblies are stored uncer 20 ft cf demineralized water.

The fuel is 93". enriched U-235 as U 03 8 combined with aluminum.

The spent fuel as-semblies are removed after each 23-megawatt-day period,.

Irradiation is l --,

done using the cama energy from acce alated.txed fission products.

This more readily simulates concitions around a reactor than does a cobalt s ou rce. Also, the higner gama activity affords shorter 4rradiation time to achieve accumulated doses.

The dose rate fear days after removal of a fuel assembly from the reactor is 1 x 106 rad /h.

The fuel assembly is 20 in. hipn.

A 20-ft-long, 3-1/2-in.-diameter pipe, with one end capped, is used for air irradiation tests.

The capped l

end is lowered into a 4-in. opening at the center of the fuel assembly. The 1

open end, above water level, is covered with an 0-ring-sealed flange to j

which is attached a steel cable and an air outlet hose.

The air inlet is located at the bottom of the pipe.

Test specimens are connected to the j

bottom of the cable and lowered into the radiation field.

Also at the l

center of the fuel assembly is a stainless steel-clad cadmium tube used as a neutron absorber.

This prevents centamination of the test specimens by l

induced radiation.
