"Weld Discre ancies on Cable Tra Su orts" The inspector performed a visual examination of cable tray hanger welds to assure that the as-built hanger and weld configurations are in accordance with the design documents.
The welds associated with the following cable tray supports were inspected:

"Review of Records'or C
Verification of Ex-Core Terminations" The NRC Construction Appraisal Team, (CAT) was concerned that ex-core termination installations were not receiving adequate gC coverage.
As a result of this concern, Bechtel added Addendum 3 to.special, CIP 695.0 to assure 100 percent.
coverage of the termination activity.
The licensee informed the inspector that approximately 40 in-.'process (}C inspection documents were missing.
This was documented on'CR No.
EX 8139 of July 25.,
1986, and dispositioned
"use-as-is".
on July 317 1986.
The licensee investigation determined that sufficient evidence existed to show that all special CIP 695.0 requirements were met since all EE580 cards (Termination Installation Cards)
are signed-off by 'the FACE referencing the special CIP 695.0 in the remarks section of each card.
In addition, other records established that the work was appropriately accomplished.

"Undersized Beam Attachment Pins" The inspector discussed the engineering evaluation with the Bechtel design engineer to assure that the undersized pins, dispositioned use-as-is, are in compliance with the original code design requirements.
Original design documents specified a 5/8-inch beam attachment which requires a 3/4-inch load pin; instead a 1/2-inch beam attachment was installed which required a 5/8-inch load pin.
The inspector's review of the engineering evaluation calculations and load rating chart showed that the smaller size brackets would withstand the existing loads and are in compliance with original code requirements.

"Undersized Melds Identified in IE Notice 85-33" The NRC issued Information Notice 85-33 on the subject of undersized weld reinforcement in ASME Code nozzle-to-shell welded joints in tanks and heat exchangers.
The licensee has performed an inspection of tanks and heat exchangers prior to the NRC CAT inspection, and similar findings were identified.
The licensee committed to review and evaluate these findings.
The licensee issued DER 86-01 to address the concerns identified in Information Notice 85-33.
The actual inspection was performed in accordance with special CIP No. 676.0.
One vessel per manufacturer was inspected with the selected nozzles being inspected for compliance to applicable vendor drawings and code requirements.
NCRs were issued to document any nonconforming nozzle-to-shell welds.
ASME Code weld strength calculations were performed on all

il~
reported undersized welds to determine if the weld had adequate strength to meet the allowable code stress.
The results of these weld strength calculations was that all welds were found to be sufficient to carry the required loads, and do not pose a safety hazard.
In addition, the MCR disposition required all undersized welds be increased in size.to be made compliant with the Code.
The licensee concluded that the condition is evaluated as not reportable under the, requirements of 10 CPR 50,.55(e)
and 10 CFR-21.
