4. Bent Thermocouple Guide Tubes.

The guide tubes on the veat valve ther=ocouples had previously been

|bv.nt when'the reactor vessel head was installed. The licensee hassince determined that these thermocouples would not be required;

for the expected power levels. The thermocouples and guide tubeshave been removed. This item is resolved.

5. Core Flood Tank Valves Malfunction

. The inspector examined Babcock & Wilcox letter of February 20, 19741 to the licensee, and the core flood system valve vendor's letter

to B&W ef September 4, 1973 " Core Flood System Valves." The vendor4 stated that machining errors were the cause of the valve malfunction,

and that the A564, Grade 360 material used wc3 an authorized sub-stitution. This iten is resolved.

6. 0A Program Breakdown on Electrical Eauipment.

The licensee has completed the corrective action on the failure of

an electrical equipment vendor to perform the quality control op-erations required in the vendor's program. The vendor's re-testprogram, dated August 22, 1973, was approved by the licensee anawas completed with no deficiencies being identified. The licensee's-

audit report 73-49, dated December 3, 1973 noted that "the testingi

was conducted as written, and that QC was provided.".

The inspector examined the results of the testing program, involvingi 7 reports, including E9048 and E8958, and no deficiencies were

identified. This item is resolved.

_ 7. Welding Filler Electrode on Maior Comoonents

The welding filler electrodes used on the steam generators were nota

traceable, as this was not a requirement at the time of manufacture.The vendor had prepared Topical Report No. BAW-1402, dated January1973, which provided the data necessary to justify the use of certain

. lots of weld filler material which had incomplete documentation ofmechanical properties. This iten is resolved.

i 8. Coolant Bleed Tank Welder Identification-

t

At a previous inspection, it was found that welder identification wasnot available for the welding on the Reactor Coolant Bleed Tank 1A.

At this inspection, the inspector examined PDM Drawing WL-1, dated.

Sep tember 11,1968 " Reactor Coolant Bleed Tank 1A" which includedthe identification of individual welders for each seam. This itemis resolved.
