COMANCHE PEAK STEAM ELECTRIC STATION (CPSES) l DOCKET NOS. 50-445 AND 50-446 SEISMIC QUALIFICATION OF HVAC SUPPORTS SDAR: CP-85-54 (INTERIM REPORT)
Dear Mr. Johnson:
On September 26, 1986, we verbally notified you that a deficiency involving discrepancies in supplier provided HVAC support documents was resportable under the provisions of 10CFR50.55(e). This is a follow-up interim report to i status the implementation of corrective actions for this issue. l The following corrective measures are being implemented to resolve this issue:
- 1. The Project organization and responsibilities for Unit 1 and Common HVAC activities have been realigned. Engineering and QC activities previously performed by Bahnson have been assumed by Ebasco and TUGCO, respectively.
- 2. The field verification effort has been expanded to encompass all
! Unit I and Common Seismic Category 1 duct supports.
1 1
Ebasco's progress to date, for this effort, is as follows:
- Collection of existing documents is complete.
l - Procedure training of walkdown engineers is complete.
- Preliminary walkdown is complete.
- Walkdown and field data collection is in progress and is being performed in accordance with TNE Procedure FVM-CS-029 (Field l Verification Method Procedure for Seismic Duct Hanger As-Built i
Verification in Unit I and Common Areas).

- 3. Engineering evaluations will be performed to ensure compliance with FSAR commitments.
- 4. Construction rework will be performed, as deemed necessary by the '
engineering evaluations of field verified information, to ensure compliance with FSAR criteria for the affected supports.
- 5. To ensure Unit 2 installations comply with prescribed requirements, Unit 2 HVAC supports are being field verified. The as-built effort is being conducted by Bahnson, with QC verification by TUGCO.
Ebasco has been given the responsibility for the evaluation of design adequacy.
Unit 1 activities are scheduled for completion by May 1,1987. Unit 2 activities are scheduled for completion in the fall of 1987.
We will submit our next report no later than Mey 22, 1987.
Very truly yours, Otw W. Counsil By:.
