| Title | Inaccurate RCS Pl Data Submittal |
| Description | An NRC-identified SL-IV NCV of 10 CFR 50.9(a), Completeness and Accuracy of Information, occurred when PPL inaccurately reported reactor coolant system (RCS) leakage values under the RCS leakage performance indicator (Pl)for both units since inception of the Pl in April 2000. PPL entered the issue in their CAP as CR 1441824, completed an apparent cause evaluation, and plans to revise Pl data previously submitted. No performance indicator crossed the Green/white threshold once the values were updated. Because violations of 10 CFR 50.9 are considered to potentially impede or impact the regulatory process, they are dispositioned using the traditional enforcement process. The inspectors concluded that PPL had reasonable opportunity to foresee and correct the inaccurate information prior to the information being submitted to the NRC. PPL\'s failure to identify and correct the recurring errors over this period of time indicated the existence of a programmatic issue. Additionally, verification of the corrected Pl data in a subsequent inspection will have more than an insignificant regulatory impact on the NRC. Accordingly, although none of the affected Pls in this case would have crossed the threshold, the NRC has determined that the violation is of more than minor significance. The finding was not considered to be more significant since had this information been accurately reported, it would not have likely caused the NRC to reconsider a regulatory position or undertake a substantial further inquiry. The significance of the associated performance deficiency was screened against the ROP per the guidance of Manual Chapter 0612, Appendix B. No associated ROP finding was identified and no cross-cutting aspect was assigned |
