Dear Mr. Madsen:
SUBJECT:
Waterford 3 SES USNRC Inspection Report 50-382/83-13 In reference (1) above, Louisiana Power & Light Company provided a description of the corrective action being taken to resolve Violation No. 1 of the subject NRC inspection report dealing with installation clearance concerns. The intent of this letter is to define the current corrective actions being taken and to update you on when full compliance will be achieved.
The LP&L Pipe Thermal and Vibration Monitoring Programs conducted as part of the startup preoperational test program addresses any clearance problems impacting thermal expansion and vibration acceptance criteria. The summary of this program and its results was transmitted to you via reference (2).
Therefore, the two phase walkdown program outlined in reference (1) evaluates existing clearances with regard to thermal and seismic interactions.
LP&L has determined that the second phase walkdown can be limited to instrumentation tubing installations required for safe shutdown of the plant since these installations are most vulnerable to damage resulting from seismic interaction with other installations such as piping, conduit, etc.
It can be demonstrated by engineering analysis that other typical installation clearances for such cases as conduit to conduit, conduit to tray, etc., will not result in the degradation of the safety related function of these installations. Therefore, LP&L believes that an area by area walkdown of such installations is not warranted. These analyses are currently ongoing and will be completed by October 15, 1983.

Mr. G. L. Madsen W3183-0289 Page 2 The following is LP&L's revised schedule for full compliance relative to Violation No. 2:
a.
The piping walkdown (first phase) will be completed by September 2, 1983 and the fol7ovup engineering evaluation will be completed by September 30, 1983.
b.
The second phase walkdown will be completed by September 30, 1983, and the followup evaluation along with the supplemental analysis discussed above, will be completed by October 15, 1983.
All other aspects of our corrective action plan relative to Violation No. 2 as well as Violation No. 1 of the subject inspection report remains the same as outlined in reference (1).
If further information is required with regard to this matter, please do not hesitate to contact me.
Yours very truly, W "?
