-- themometer or a calibrated humidity recorder (Bristol 406g TH or equivalent) shall be used to detemine relative humidity. The dew pc int shall be determined by the difference in the dry and wet bulb temperatures using the U.S. Department of Commerce Weather tureau Psychrometric Tables, W.B. No. 235. When dry bulb readings are greater than 100*F, the dew point and relative humidtty should be detemined using the 100*F reading (note in remarks). The surface taperature shall be detemined by placing a calibrated surface taperature thermometer (0mega - hprove Fastep, Range 10-250"F) in contact with the substrate surface to be blast
. cleaned. The themometer probe shall remain in contact with the surface until the taperature reading stabilizes.
Final surface preparation shall not begin unless tapersture of the surface is a minisum of 5'F above the dew point.
3.1.2 Abrasive Accantability The Inspector shall obtain a sample of the abrasive to be used fra each work area. The abrasive shall be verified to be dry by feel. All grease, oil and deleterious material is unacceptable.
Verify that acceptable blast abrasive is used.
3.1.3 Blast taui- at Accee+aility The inspector shall perfom the following inspections / tests to detemine acceptability of blast clean < ng equipment prior to uses
- a. Verify that water separators are installed in air supply system and that the separators have been drained of accoulated uter and drains lef t partially open.

examined for evidence of contamination (oil, water, foreign matter, etc.). No evidence of contamination is acceptable.
3.1.4 561 vent Cleaning (If Contamination Is Present)
If oil, grease, or other contamination is present, verify that solvent cleaning (in accordance with SSPC-SP-1) is perfonned and that all contamination is removed prior to blast cleaning steel surfaces.
3.2 POST BLAST CLEANING OPERATIONS 3.2.1 Blast Cleanuo Tiis inspector shall visually check the blasted substrate su rface. .
The surface shall be brushed or vacutmed to the extent required for final surface inspection. The adjacent areas shall be cleaned to the extent necessary to avoid contamination during subsequent coating applications. ,
3.2.2 Blasted Surface Acceptability The inspector shall perfonn the following inspections to detennine acceptability of the blast cleaned surface:
- a. Absence of Foreign Matter -- A visual inspection shall be perfonned to detennine that all oil and grease, di rt, millscale, rust, corrosion products, oxides, paint or other foreign matter have been completely removed fra the surface except "for light shadows, very slight streaks or slight discolorations caused by rust stains, mill scale, oxides, or slight, tight residues of paint or coating that nay renain. At least 95 percent of each square inch of surface area shall be free - of all residues, and the renainder shall be limited to light discolorations as mentioned above.

Weld splatter on structural steel shall be removed by either grinding or sand blasting. However, if the weld splatter should' remain after the above d ' operation, the weld splatter will be acceptable.
Sharp projections are not acceptable. .
Protrusions and peaks shall be ground to a rounded contour.
- c. Anchor Pattern Depth -- The anchor pattern depth of the blasted surface shall be inspected at random locations using a Keane-Tator Surface Profile Comparator (model 373) or approved equal. l The anchor pattern depth for a surface shall be a minimum of 1.0 mils. -
d.' For repairs of blasted surfaces, power tooling my be utilizea as required.
3.2'.3 Unique Number Identification After blasting and prior to prime coat application, QC shall i
verify that construction has identified each peice with a unique nunber in accordt.nce with References 1-A and 1-B.
The QC Inspector shall maintain a Protective Coatings Unique l
Identification Number Log, Attachment 1 for all protective l
coatings application on al1 steel designated for use in the Reactor Building. Subsequent subdivision of coated steel in the field or shop shall be witnessed by QC in accordance with Reference 1-C.
l NOTE: ,
A. Unique nunber may be assigned to a lot of material to be prime coated at the same time. For example, six pieces steel to be coated at same time may all have same unique number.
i B. Liner plate is excluded from QP ntsnbers. .
Equipment which is identified with a permanent plant identification nunber need not be identified with a Protective Coatings unique Identification Number.
