SUBJECT:
SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION RESPONSE TO NRC INSPECTION FINDINGS DOCKET NOS. 50-498/79-15 AND 50-499/79-15
Dear Mr. Seidle:
The following is Houston Lightin; 6 Power Company's (HLSP) response to the item of noncompliance identified in IE Inspection Report Numbers 50-498/79-15 and 50-499/79-15, dated October 19, 1979.
A.
Failure to Follow Concrete Consolidation Procedure Corrective Action The lack of vibrator penetration referenced by the Resident NRC Inspector in Report 79-15 has to do with leveling the "as-placed" concrete prior to the process of vibration.
This is a common practice and was explained to the Resident NRC Inspector by the Brown 6 Root (B5R) roving inspector.
The Brown G Root roving inspector did direct the area to be re-vibrated as an initial reaction to the Resident NRC Inspector's observation; however, in subsequent discussions with the construction foreman, it was determined that the vibrator operator was leveling concrete in accordance with his instructions. The concrete received a thorough vibration subsequent to the IcVeling process, as called for by procedure, and this was verified by Brown S Root Quality Control l
Inspectors.
