2. 0 E AND SCOPE .

This instruction shall describe methods to be utilized by Quality . Control in the measurement of dry film thickness (DFT) and adhesion to concrete substrates of existing j r.oncrete coating applications described in Reference 1-A i .using the Mark II Tooke Gage and the Elcometer 106 Adhesion l- Tester respectively. The above tests are destructive in  :

~ nature wh'ich will necessitate a repair of the coating system i at each test location. '

3.0 INSTRUCTION For all coated concrete surfaces for which documentation is I missing or discrepant, the inspection activities discussed in Paragraphs 3.1 through 3.2 shall be performed as B

indicated therein.

3.1 TOOKE TEST (SCRATCH TEST)

The scratch test of the REACTIC 1201 finish coat shall be j performed using a Mark II Tooke Inspection Gage equipped with a 2x tip. Five separate readings spaced randomly over

each finish coated area of 100 square feet or less shall be taken.

i NOTE: Tooke tests are not required to be perfomed on

. areas of concrete which have not been finish

, coated with REACTIC 1201.

l Acceptance Criteria The acceptable range for dry film thickness of the REACTIC 1201 finish coat is 3 mils minimum and 12 mils maximum.

1 In the event that any reading (s) is found to be outside of the acceptable finish coat thickness range, additional readings shall be taken to detennine the extent of the I .( unacceptable area. Results of additional testing shall be

, documented in the " Remarks" section of Attachment 1. t i , 3.2 ADHESION (PATCH TEST)

The QC Inspector shall perfonn an Adhesion (Patch) Test on

~ each 500 square feet or less of concrete surfaces which have been previously coated with surfacer only (NUTEC 11 or 115) o r, wi th surfacer and finish coat (REACTIC 1201). A j calibrated Elcometer 106 Adhesion Tester shall be used to verify that the minimum acceptable tensile strength of I adhesion of the coating to the concrete substrate has been i

i obtained. For test areas of 300 square feet or less, each

' test shall consist of three (3)' dollies randomly spaced and tested to failure. For test areas greater than 300 square

i. feet but less than or equal to 500 square feet, each test shall consist of cne (1) dolly tested to failure for each

, , 100 square feet or fraction thereof.

7 For test area of 450 square feet, test i

EXAMPLES: 1.

5 dollies to failure.

2. For test area of 350 square feet, test
  • 1 4 dollies to failure.

T

3. For test area of 100 square feet, test i

3 dollies to failure.

CPSES QI-QP-11.4-24 2 FEB 2 5 1962 3 of 5 Acceptance Criteria:

The minimum acceptable strength per dolly shall be 200 psi.

If a dolly should fail the minimum strength criteria, the following additional adhesion testing shall be perfonned:

Four (4) additional dollies shall be adhesion tested at approximately one foot from the failing dolly and spaced radially at approximately 90 degree intervals. If any of the additional dollies should fail the minimum strength cri teria, the test res'ul ts shall be promptly reported to Civil Engineering for evaluation and resolution. Test results on the additional dollies shall be documented in the

" Remarks" section of the IR.

NOTE 1: In the case in which all of the additional dollies pass the minimum strength criteria, test failures

, on any of the original three (3) dollies shall

( nevertheless be documented as " unsatisfactory" on

, the IR. -

3.3 REPAIRS Repairs of each coated area which has been destructively tested per Sections 3.1 and 3.2 shall be performed in accordance with Reference 1-C and inspected in accordance with Reference 1-0.

3.4 DOCUMENTATION Results of all inspections described in Sections 3.1 through

. 3.2 shal' be documented on an Inspection Report, Attachment 1, in accordance with Reference 1-8.

3.5 MAPPING For each IR generated in accordance with Section 3.4, a sketch shall be attached to indicate the location and size of the applicable coated concrete area (See Note 1). The individual

', sketches from each IR shall be used to prepare composite maps which shall cover in scope a specific room, compa rtment, cuadrant, or cavity within the Reactor Containment Buildings.

The IR number shall be transferred to the applicable area on the composite map in order to provide traceability to the IR.

instruction within a given area have been reinspected and mapped. Each completed composite map shall be transmitted to the Permanent Plant Records Vault.

a. Bottom and Top Elevations (vertical and diagonal surfaces) or Elevation of Surface 4

(horizontal surfaces).
