into 4" squares eight. layers thick. Wearing clean, plastic i

or rubber gloves flush each cloth sqs.re three (3) times with approximately 300 ml. demineralized water per rinse to

rinsed with demineralized water. Tie the bag thoroughly to climinate drying of the cloths.

Cloths should be rewet prior to use, if stored longer than one day.

3.1.1 Test Sample i

Remove two 4" square cloths from the bag while wearing plastic s

l gloves.

One cloth is to be a blank use the other cloth to wipe an area of approximatley 20 dmE (2ft.2) on the surface of the stainless steel to be sampled. Place sampling cloth and blank cloth in individual rinsed' polyethylene l(

bags.

Only one blank is required for each 1 to 10 sa=ples g

s Chloride and fluoride acceptance limits depend on the cleanli-ness classification. The class of cleanliness required for typi-cal applications is as shown in Table 1 (frcm Reference 1-B) unless -

approved otherwise by Engineering. As shown in the table, the in-4' (

ternal or external surfaces of individual parts of the same com-ponent may have different cleanlinese classification.

The chloride and fluoride limits of these cleaning classifications are as follows:

Class A and Class B 2

by item basis after approval by the Cwner.

The Contractor shall submit his procedures for acid cleaning or passivation of stainless steel as applicable prior to use.

2.16.10 Inside surfaces of lubrication system oil piping shall be protected from rusting by oiling or by a

ru s t preventative meeting the following requirements:

a.

The oil used is to be ecmpatible with the operating oil used in the system (Gulf oil Coat TD with vapor phase inhibiter).

(

b.

Rust preventatives other than "a" above shall be of a

light-duty liquid film type or a heavy-duty solid film type oil which is readily removed by the flushing oil.

The Contractor shall submit his selected rust preventative to the Owner for approval prior to use.

teria Components shall be clean to the extent that no contaminaticn exceeding the limits of this paragraph is visible to a person with no rmal visual acuity, natural or corrected.

Lighting during inspection shall provide a lighting level of at least 100 footeandles on surfaces being inspected.

All internal surfaces shall be free of mill

scale, organic
coatings, grease, oil and debris.

Cleaning and lighting for inspection of stainless steel piping shall conform to ASTM A-380 requirements.

b.

Acceptance standards of stainless steel materials are as fc '. ows :

1.

Iridescent temper films resulting from heat treatment and tightly adherent black oxide films that occur on the back side of welds need not be removed except if the oxidation will interfere with subsequent inspect.ons.

i 2.

Thin films of rust are acceptable on final cleaned

surfaces, as defined below, provided there is no evidence of corrosion pitting.

Y l

Gibbs & Hill, Inc.

Specification 2323-MS-100 Revision 8 July 5, 1984 Page 2-23 a.

The rust covered area of components in contact with the Reactor Coolant system shall not exceed one percent of the total surface area of the piece being inspected.

b.

The rust covered area of components other than "a" above shall not exceed 10 percent of the total surface area of the piece being inspected.

NOTE:

The persistent occurrence of rust on clean corrosion-resistant material may indicate something wrong with the material (for

example, improper heat trea tment or material composition) and the cause of the ru st should be determined.

3.

Lccalized pitting shall be removed from surfaces by grinding or by other suitable means as approved by the Owner.

Minimum thickness requirements shall not be violated.

The repair shall be blended smoothly inte the adjacent base material.

Repairs shall be reported and documented accordingly.

The consistent presence of basis for placing a " hold" on the pitting shall be a

material until the cause of the defects can be established and the effects eliminated.

glllllinadvertentpaint In regard to examining stainless steel pipe surfaces for smears, the following procedure shall be follcwed:

On piping systems with a design temperature of 300*F or less:

M All paint on surfaces that is visible and W

accessible shall be removed.

gf Surfaces for which visual inspection is not feasible, (such as adjacent to pipe supports),

pressure spraying with all the following liquids shall be used to clean the pipe:

first, MEK, or approved liquid penetrant cleaner, next, acetone or ethyl alcohol, finally, demineralized water.

used, proper
piping, valving and procedures shall be used to prevent sucking contaminants into the component.

Minor drying marks are not ob; e c tio nab '.e.

When special drying is desired by the Cwner, the Contractor shall, after drying, evacuate the piping system to at least two inches Hg below barometric pressure, fill with dry air to prevent further or nitrogen to a positive pressure and seal air flow.

Periodic pressure checks shall be made by the Contracter so that the positive pressure is at least 0.2 psig.

2.16.14 Cleaning Requirements Prior to Insulation of Stainless Steel Piping and Equipment All stainless steel pipe and equipment shall be cleaned prior to insulation by vacuuming, wiping, blowdown with clean, oil-free compressed

air, or flapping / grinding.

When compressed air is

The surface shall be free of particulate contaminants such as sand, metal chips, weld slag, etc.

It shall also be free of organic film and contaminants such as oils, paint, and preservatives, as determined by visual examination.

If surfaces fail to meet this criteria and degreasing is required, Steddard solvent, mineral spirits, isprophyl

alcohol, ethyl
alcohol, acetone, toluene, methyl ethyl ketone, Magnaflux cleaner / remover or any other cleaner that is approved for use on stainless steel can be used.

All stainless steel piping and equipment surfaces shall be rinsed with Grade "A" water (see appendix 6) after cleaning.

All stainless steel lines and equipment inside the containment building that are insulated with reflective insulation shall hav.

a swipe test performed in accordance with Contractor's procedure Ql-QP-il-1-65, to determine the chloride and fluoride surface contamination levels.

No swipes are required on all o ther stainless steel pipe or equipmeat, but should be cleaned in such a manner to achieve the same acceptance criteria.
