Licensee Action on Previous Inspection Findings (0 pen) Unresolved item 413/79-16-02, Cable tray hangers not installed per drawings. The licensee has issued Nonconforming Item Reports (NIR) 6358, 6370, 6371 and 6396 concerning this item. The scope of each of the NIR;s is as follows:
NIR 6358 documents the installation of a 3/8" x 6" x 10" steel plate a.
on hanger 1 HA5C in lieu of a 3/8" x 7" x 10" plate as required by drawing CN-1903-04, R7.
Evaluation / disposition of the NIR has not been completed.
b.
NIR 6370 documents three longitudinal brace connections on hanger 1 HA6C as not being per the requirements of detail "B", HS-58 of drawing CN-1903-05, R3.
This item was identified by the licensee during subsequent inspection of the hanger 1 HA6C installation. The incorrect installation has been attributed to a dimensional error in the location of the unistrut fittings connecting the rungs to the hanger legs on HS-57 of the design drawings which prevented installation per detail
"B" HS-58.
Variation Notice (VN) 7225 has been issued to correct the drawings and allow Jongitudinal brace installation per detail "B",
HS-58.
NIR corrective action requires hanger rework per VN 7225 and reinspection.
The licensee's corrective action has not been completed for NIR 6370.

CN-1903-05, R3 and CN-1893-05, R7.
Drawing CN-1903-05 requires lengths L2, L3 and L4, of hanger 1 HA6C to be 5'-6", and drawing CN-1893-05 requires L2, L3 and L4 to be 5'-8".
Additionally, drawing CN-1893-05 requires L1 to be 3'-6" whereas the installed L1 is 3'-8".
L1 exceeds the plus or minus 1" tolerance specified by note 18 of CN-1903-01, R13.
Licensee evaluation / disposition of NIR 6371 has not been completed.
d.
NIR 6396 documents installation of hangers 1 HASC and 1 HA6C as not being per de rign drawing requirements altuough QC inspections per procedure Ci-301 had been completed. Although not completed, NIR 6396 corrective actions are as follows.
(1) Revise QA procedure M-41B, serial number 2, to document individual hanger inspections.
(2) Revise procedure CP-301 to control work on inspected hangers including modification of inspected hangers after acceptance by QC.
(3)
Initiate QA surveillance program to ensure hanger inspections are being performed per procedure requirements.
(4) Train QC and craft personnel on revised procedural requirements.
It was determined by the licensee that the two anchor bolts for the hanger 1 Hl.5C mounting plate did have sufficient engagement, and the licensee removed the excess washers from the bolt installations.
Although the licensee had completed weld and bolt torque inspections per DPC procedure CP-301, complete hanger installation inspections per the requirements of M-41B, serial number 27 had not been performed.
This item will remain open pending completion of licensee evaluation and implementation of corrective action.
