Dear Mr. O'Rei lly:

Re:

St. Lucie Unit 2 Docket 50-389 IE Bulletin 80 Examination of Containment Liner Penetration Welds Florida Power 8 Light Company has reviewed IE Bulletin 80-08 in regard to ultrasonic examination of containment penetration welds with likelihood of undetectable indications.

As requested in item 1 of the Bulletin, our facility utilizes the flued head design for penetration connections and also the other design with containment boundary buttweld between the penetration sleeve and process piping.

We are presently investigating the records on the subject welds on penetrations at the vendor's facility and the field to obtain necessary information requested in the Bulletin.

However, the enclosed Attachment 1 provides information relative to it;em 2c of the Bulletin that is now available.

Additional information requested in the Bulletin per items 2a, b, d and 3 as applicable, will be provided upon completion of our investigation.

This will serve as our interim response to IE Bulletin 80-08 and our final response to this Bulletin will be submitted prior to September 30, 1980.

Very uly yours, obert E. Uhrig Vice President Advanced Systems 8 Technology REU/PP/ah Attachments cc:
