TXX-88757 October 28, 1988 Page 2 of 2 The following is the status of the remaining corrective actions being implemented to resolve this deficiency:
1 The revised estimated completion date for development of the corrosion monitoring plan to monitor SSW System corrosion rates is December 1, 1988.
2.
Draft operating procedures (as described in item 5 of the corrective actions contained in TXX-88476) are in review.
The estimated approval date for issuance of these procedures has been revised to December 1, 1988.
3.
As previously stated in TXX-88476, the replacement of water absorbing gaskets with non-water absorbing gaskets is being done on a case-by-case basis as the flanges are opened for maintenance or other reasons.
Additionally, it was previously comitted in TXX-4762 to eliminate a flow induced vibration problem at 1-SW-026 via use of a longer pipe nipple.
This problem was actually eliminated by utilizing a shorter, thicker pipe nipple.
Our next rcoort, which will be submitted no later than July 29, 1989, will detail our corrective actions for Unit 2 installations.
Very truly yours, W2
