SUBJECT:

COMANCHE PEAK STEAM ELECTRIC STATION (CPSES) 00tKET NOS. 50-445 AND 50-446 ROSEMOUNT TRANSMITTERS SDAR: CP-84-28 (FINAL REPORT) l Gentlemen:

On November 19, 1984, we notified you by our letter, logged TXX-4364, of a deficiency regarding transmitters with a potential leakage path between the sensor module and housing which we deemed reportable under the provisions of 10CFR50.55(e). This item was subsequently identified by our last report logged TXX-6435, dated May 13, 1987, as an item for which the corrective l actions were formulated but the schedule for the implementation of those actions was not established. This is a final report submitted to status I corrective actions which have been implemented.

As previously stated in our report logged TXX-4364, the affected transmitters were documented on nonconformance reports (NCR) I-84-100466-S (closed December 16,1986) for Unit 1 and NCR I-84-200169 (closed October 29,1984) for Unit 2.

In accordance with the NCR's, the affected transmitters have been repaired or reworked at either the supplier's facility or the site and reinstalled.

, Supporting documentation is available at the CPSES site for your Inspector's review.

Very truly yours, IJ . C . M W. G. Counsil By: .
