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 containment liners and radiation areas in accordance with specification, drawing, and manufacturer's requirements. This procedure may also be used for coatings to any steel substrate inside the reactor buildings scheduled to receive primer of Dimetcote 6 and Phenoline 305 finish coat manufactured by Ameron and Carboline respectively.

1.2 SCOPE 1.2.1 The scope of this pocedure covers the surface preparation and coating of Unit i and 2 steel substrates inside the reactor buildin;s and radiation areas scheduled to receive protective coatings.

1.3 GENERAL DISCUSSION 1.3.1 All coating =aterials covered by this procedure shall be as

=anufactured by Carboline Corporation of St. Louis, Missouri and Ameron Protective Coatings Division of Brea, California. The coating system shall consist of a prime coat of Dimetcote 6 by Amaron with a finish coat of Phenoline 305 by Carboline. To protect the prime coat from prolonged exposure, a " seal coat" consisting of approximately one mil DFT of Phenoline 305, thinned at 50: =ay be applied over the prime coat. Finish coating shall be applied when convenient.

In order to maintain traceability on protective coatings applied to shop coated steel cited for installation in the Reactor Building, these items shall be steel stamped with a unique coating code number. The code numbers shall be assigned by QC Paint and applied by craf t personnel. Upon division of materials, this unique number vill be transferred along with all other unique identifying numbers.

1.3.2 Vendor coated items shall have coating systes verified for compliance to site specification prior to any additional coating or coating repair.

1.3.3 "5en there is a conflict between this procedure and Reference 5, the requirement of Reference 5 shall prevail.

Small amounts of grease or oil deposits =ay be removed by blast operations. Final blasting shall not begin unless the temperature of the surface to be blasted is 5'T or more above the dew point. The surface shall be cleaned by blasting to SSPC-SP-10. "Near White Blast" cleaning. Blasting operations shall be performed with blast abrasive which will achieve a minimum profile of 1 mil. After the above surface preparation, the surface to be primed shall be air blasted and/or solvent wiped to re=ove dust, sand or foreign contaminants from the surface. Air blasting shall not be performed where air-borne contaminants could adhere to tacky paint. Sufficient time shall be provided to allow suspended particles to settle before beginning primer application. If rust forms af ter surface preparation, the

, rusted area shall be reeleaned before primer application. Generally a blast cleaned surface shall not be exposed for more than 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> prior to priming without additional cleaning of the surface. 'a he n applying coatings that will be joined together by a later coating operation, the interface shall be constructed as follows:

a. Blasting using no border tape - Overblast the staal to near white metal approximately 12" - 18" beyond the point which will receive primer. Hold back approximately 12" - 18" from edge of blasted area when applying primer.
b. Blasting using border tape - Clean the steel to near white metal approximately 3" - 6" beyond the point which will receive prime r. Place border tape approximately 1" in from the edge of cleaned area and prime. When applying seal or finish coat on either of the above methods hold back approximately 12" - 18" from edge of primer.

3.1.2 Removal of weld spatter and other minor surface imperfections (not to exceed .031" for containment liners) - if needed, veld spatter omitted by others will be removed by Painting Persennel in accordance with SSPC-SP-2 and SSPC-SP-3. If it is determined that surface defects are sever enough to require later repair, the area to be repaired will be blocked out and spot painted at a later date. All protrusions and peaks shall be ground s a rounded contour.

Zine filler shall then be added under constant agitation and mixed until free of lumps. Partial mixes shall be mixed by weight in a proportion of 6.4 parts base to 15 parts zine filler using a suitable scale to achieve a plus or minus 2 percent accuracy. The mixture shall then be strained through a 30-mesh screen.

NOTE: Inorganic zine primer shall be power mixed or " boxed" prior to use.

3.3 APPLICA!!ON OF PRIME COAT '

The primer shall be allowed to become tack free before start of other construction operations which could create contamination problem .

Any runs or sags having a detrimental ef fect on the coating system shall be removed and repaired. The following application parameters shall be followed:

4. Normal conditions of ambient and surface temperature shall be

. 40* to 120'T and 40' to 130*F respectively. Primer may be applied within an ambient range of O' to 130'T and a surface temperature of O'T to 200*F. Nornal thinning of Dimetcote 6 is th pints per gallon. Application during other than normal conditions;

rely on " coin test" method for determining cure.

" Coin Test" is defined as: the coating is suffietently cured for topcoat when the coating may be burnished rather than removed when rubbed with the flat portion of a coin such as a nickel.

If required, the cure of Di=etcote 6 may be accelerated by use of water spray after allowing at least one hour cure after application. This shall be done as required using clean water having a pH range of 6 to 3. If used, a filter system will be installed in order to assure proper cleanliness of the curing water.

3 Pri=er application shall not begin unless the surface temperature is a minimum of 5'F above the Dew Point.

3.4 PREPARATION FOR FINISH COAT 3.4.1 Verify primer surface ready for finish coat.

3.4.1.1 If no primer defect exist, solvent wipe surface and allow solvent to flash off surface. Apply finish coat. Prime showing defects shall be repaired per 3.4.2 using conventional spray. equipment or brush application per Note 2.

3.4.2 Primer Defects and Repair Methods

a. Sags or runs in excess of 5.5 mils shall be abraded as required to 2.0 to 5.5 mils. Sags or runs 5.5 mils or less which show no evidence of muderacking need not be repaired. If coating surface is satisfactory after abrading, then Carbolines finish coat may be applied.

Pot life of Phenoline 305 is shown on Attachment 3. The finish color shall be as required by the governing specification.

3.6 FINIS'd COAT APPLICATION 3.5.1 Finish Coat: Carboline, Phenoline 305 Finish coating shall be applied using conventional, airless, brush or roller. k' eld seams, edges and other sharp geccetrical discontinuities may receive an initial coat of 1-2 mils finish coating thinned by using two quarts Phenoline Thinner per each gallon kit of Phenoline 305. To aid in continuity at edges, edges may be " striped" with Phenoline unthinned instead of the 50* mixture as stated above. In either

" striping" or initial coating of edges, welds, etc., time should be allotted for the coating to harden su. ficiently to maintain a "sesling" effect prior to continuing coating opera-tions. The initial coating of edges, striping, etc., as stated above, shall be considered part of the total ia tial finish coating operation. The material shall be allov.4 to become tack free before any other construction operatiens proceed which could create contamination problems by dust or other foreign matter. A continuity check may be performed in accordance with NACE T-6F-3 Condition "C". No ;ross dis-

' continuities are acceptable such as holidays, voids, skips, bubbles, and misses. Any runs or sags having a detrimentti effect on the coating system shall be removed and repaired.

The following application parameters shall g)vern

.a . The permissible range of surface and ambient temperature for application shall be 50' - 120' F.

Temperature may rise above 120' F af ter satorial has become " tack free". Phenotine 305 may be thinned up to 2 quarts of Phenoline Thinner per gallon mix.

The ratio of thinner to Phenoline will be that which gives the best workable mix, i.e., usually advantageous to use more thinner at lower temperatures.

b. Minimum and maximum values of relative humidity shall be 0% and 85% respectively.
