| Title | Licensee-Identified Violation |
| Description | On August 4, 2010, a control rod was withdrawn from step 12, past the desired step 24, to step 36 during power ascension. PCOs identified the performance error prior to executing the next procedural step. This human performance error is a violation of TS 5.4.1, Procedures, for failure to comply with a procedure for reactivity control. The finding is more than minor because it affected the Barrier Integrity cornerstone objective of reactivity control and affected the configuration control attribute, specifically control rod position and its potential impact on the fuel cladding. The violation was evaluated using IMC 0609 Attachment 4, Table 4a, and determined to be of very low safety significance (Green) because it was associated with a degraded fuel barrier. The issue was entered in PPL\'s CAP as CR 1289395. |
