"3.
On January 31, 1988, a portion of an unidentified drawing marked
'Information only' was used to perform work on centainment spray system flow indicator 2-FI-72-34."

Reason for the Violation s
As stated in TVA's response dated March 29, 1988, "On January 31, 1988, maintenance work was performed on the containment spray pump 2A flow loop 2-F-72-34.
The work to be performed consisted of backfilling the low-side sense line of 2-FM-72-34A, 2-Rt-72-34B, and 2-FI-72 34 in accordance with SI-203."

This investigation did reveal that AI-25 could be a contributing factor with an incident of this type in that it could be misconstrued. However, because no objective evidence can be established regarding this situation and because TVA fully agrees with the technical merits regarding use of drawings, TVA does not take issue with the violation.

The incident has been discussed with the employees involved, and they are aware of the procedural requirement to use only controlled drawings or controlled prints.
