W.J.WO0lley00. itt chment ,1 McCUIRE AIR LOCK DOORS SHOP INSPECTION PROCEDURE REVISION 0, 10/10/79 1.0 SCOPE This procedure is intended for use on Personnel Air Lock Doors for McGuire Nuclear Station Units 1 and 2.
2.0 PURPOSE Inspection of drilled and tapped holes in door seal plates.
3.0 PROCEDURE 3.1 Identification 3.1.1 Each hole for each door has a unique identification
~
as shown on drawings 36972 through 36979.
3.1.2 A map is included on each of the above drawings. It is to be completed with the appropriate measurements as evidence that each inspection stop has been completed.
3.2 Depth 3.2.1 Renove the inflatable seals and keeper bars.
3.2.2 A depth gauge with a 60* included angle pointed plunger shall be used.
3.2.3 The depth of each hole for the outer seal row A and the inner seal row A shall be measured and recorded on the map. Based on the thickness of the door plate and the depth of the hole, taking into account tolerances, those that are determined to be drilled through shall be rejected.
3.3 Thread Quality 3.3.1 A "Go - No Go" type thread gauge to measure a Class 3 threaded hole shall be used.
3.3.2 The threaded gauge shall be screwed into each hole.
The "Go" portion should go in to a minicum depth of 1/2 inch. The "No-Go" portion should not be able to be screwed in. Those holes that do not meet the above criteria shall be rejected.
3.3.3 An attempt shall be nade to correct rejected threads by running a tap into the hole. The thread gauge
" test procedure should then be repeated.

McCUIRE AIR LOCK DOORS
- SIOP INSPECTION PROCEDURE REVISION 0, 10/10/79 3.0 PRECEDURE (continued) 3.4 Angularity The angularity of each hole shall be determined with the thread gauge in the hole. The counter line of the hole shall be 90* I *3 with the surface of the plate or the tangent of the curve. The maximum angle should be recorded on the map. Those holes that are off by more than 3* shall be rejected.
3.5 Documentation 3.5.1 The map shall bear the signature of the inspector (s) and dates.
3.5.2 The sign-off may be performed for each measurement recorded, or performed in groups of measurements made by each inspector. If one inspector performed all the inspections only one signature and date is required.
3.6 Repair Those holes which are rejected shall be repaired in accordance with drawings 36972 through 36979. The repairs shall be accomplished using approved welding procedures, and following the fabricators Quality Assurance Program.
