Dear Sir:

th Texas Project Units 1 & 2 Docket Nos. STN 50-498, STN 50-499 Second Interim Report on Damage to The Steel Liner Plate in the Unit 2 Reactor Containment Building In the first interim report (ST-HL-AE-433) dated March 24, 1980, Houston Lighting and Power provided a logic for the Unit 2 Resctor Con-tainment Building liner bulge repair. Provided for your information is a summary of the progress performed to date regarding the repair of the liner bulge.

- Pittsburgh Des Moines Steel Company, the containment liner sub-contractor, has completed the removal of the deformed liner plate.

- A detailed mapping of the extent of the removed liner plate has been completed. This information has in turn been provided to Pittsburgh Des Moines Steel Company in order that they may de-velop detailed shop drawings and procedures for the repair of the liner plate. Discussions with Pittsburgh Des Moines Steel Company have indicated that the detailed drawings and procedures should be received shortly.

Examination of the concrete following the removal of the deformed liner plate has failed to disclose any unexpected or unusual con-crete void formations.

- The logic previously issued is currently undergoing revisions and will be submitted upon its completion.
