DOCKET NOS. 50-445 AND 50-446 SEISMIC QUALIFICATION OF HVAC SUPPORTS SDAR: CP-85-54 (FINAL REPORT)
Gentlemen:
On September 26, 1986, we notified you by letter TXX-5043 that a deficiency involving discrepancies in supplier provided HVAC support documents was reportable under the provisions of 10CFR50.55(e). Our last interim report logged was TXX-6106 dated November 20, 1986. This is a final report to status the following corrective measures:
- 1. The Project organization and responsibilities for Units 1 and 2 HVAC activities have been realigned. Engineering and QC activities previously performed by Bahnson have been assumed by Ebasco and TV Electric, respectively.
- 2. The field verification effort has been expanded to encompass all Unit 1 and 2 Seismic Category I duct and duct supports.
Ebasco's progress to date, for this effort, is as follows:
O Collection of existing documents is complete for Units 1 and 2.
O The as-built inspection of duct supports in Unit 1 and Common has been completed with the exception of areas which will be verified.
The as-built inspection of ductwork in Unit 1 and Common is currently in progress and is being performed in accordance with TU Electric Procedure CPE-FVM-CS-029, " Procedure for Seismic HVAC Duct and Duct Hangers As-Built Verification in Unit I and Common Areas." -

- 3. Engineering evaluations are being performed to ensure compliance with FSAR commitments.
- 4. Construction re-work was initiated on May 4, 1987, as deemed necessary by the engineering evaluations of field verified information, to ensure compliance with FSAR criteria for the affected supports.

- 5. QC inspections of the Seismic Category I duct and duct supports will be performed after an engineering review of the construction re-work.
- 6. An as-built and design verification effort, and QC inspection will be performed on Seismic Category I duct and duct supports in Unit 2. This program will be performed in the same manner as the one utilized in Unit 1.
Unit I activities are scheduled for completion by March,1988. Unit 2 4
activities are scheduled for completion in July,1988.
