WBN (Watts Bar Nuclear) Unit 2 (under cons … WBN (Watts Bar Nuclear) Unit 2 (under construction) determined that a portion of a number of instrumentation lines within multiple systems may have not been inspected completely for proper slope. This condition may have resulted in sense lines being installed with less than the 1/4" per foot minimum slope. No confirmed examples have been identified that would have created a substantial safety hazard at this time. However, walkdowns and evaluations are still underway to confirm that no substantial safety hazards exist. If any examples are found, they will be corrected prior to system turnover to Plant Operations. Therefore, at this time, the safety significance remains indeterminate. This issue has been documented in TVA's corrective action program as Problem Evaluation Report 680826 and is being conservatively reported as a programmatic breakdown by WBN Unit 2 under 10 CFR 50.55(e).</br>The licensee has notified the NRC Resident Inspector.e has notified the NRC Resident Inspector. +
