SUBJECT:

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).

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.
