3.7.2 Repair of Minor Defects The QC inspector shall perfonn the following inspection when repairing minor defects (as defined by Reference 1-B or 1-C):

a) Verify ambient conditions per Section 3.2.2(a) prior to surface preparation, b) Verify that the damaged area'*is blasted or abraded and any exposed steel is ground per Reference 1-B or 1-C.

c) Verify damaged area is solvent wiped in accordance with Reference 1-B or 1-C.

d) Perfonn inspections described in 3.3.1, 3.3.2, 3.3.3, 3.3.4, 3.3.5, and 3.4 3.7.3 Repair of Major Defects The QC inspector shall perfonn the following inspection when repairing major defects (as defined by Reference 1-B or 1-C):

a) Verify ambient conditions per Section 3.2.2(a) prior to surface preparation.

('-

b) Verify area is abraded or spot blasted per Reference 1-B or 1-C.

3.7.4 Repair of Embedded Foreign Particles The QC inspector shall veri fy that embedded foreign particles are removed and the surface recoated per Section 3.7.5.

3.7.5 Repair of Pinholes and Discontinuities, Over Spray, Dry Spray ,

and/or Overcoating i a) Verify all loose particles are removed and area is solvent wiped.

b) Perfom inspections described in 3.7.2, except pinholes and small dicontinuities may be repaired at the time of final inspection wi thout a later i reinspection of the repair.

3.7.6 Documentation of Repairs l All repairs shall be documented on an Inspection Report, Attachment 1. Repairs involving application of primer will be documented on Attachment 3. l I

3.8 MAPPING OF LARGE AREAS For large areas (such as reactor containment liner plate) which have received coatings prior to 10/23/81 (Issuance date of Rev. 5 of this procedure), a unique number shall be assigned to the original inspection checklist. This number '

will be transferred to the area on a map drawing to provide traceabili ty to the original checklist. For any coatings applied af ter 10/23/81, the IR number shall be transferred to the area on the map drawing.

The map drawing shall be maintained by the QC Supervisor, or his designee, until the entire surface has been coated.

At this time, the completed map shall be transmitted to the Pemanent Plant Records Vault.

NOTE 1: Separate maps shall be maintained for the prime, seal and finish coats.

NOTE 2: If the coated area applicable to a given IR is irregular in shape, a sketch should be attached to penn no.1 Tuoco CA

    • These are theoretical values. The next page contains graphs of-the theoretical and actual LOCA temperature and pressure curves. The data for the ictual IOCA curves are taken from the chart recording for this test, which is stored in lab book #230, page 57 .'

i Note: Test was interrupted to place spray nozzle in LOCA chamber. Time was added to test to make up for interruption.

GRADING PROCEDURE: The test coupons were evaluated for performance in the following' areas:

l

1) Material flaking off. 2) Delamination between coats and/or peeling. 3) Blistering of the topcoat. 4) Chalking of the topcott.
5) Excessive cracking.
