Finding

Title

Reactivity Management Procedures Not Maintained in Accordance with Industry Standards

Description

The inspectors identified a Green NCV of TS 6.8.1a for not maintaining operating procedures in accordance with NRC and industry standards which required prudent, conservative lowering of reactor power prior to performing evolutions which had the potential to affect reactivity. The inspectors determined this procedural inadequacy was a performance deficiency that was within Exelons ability to foresee and correct. Exelon has documented no immediate corrective actions but has entered this issue into the corrective action program for resolution as IR 1355895. There were no similar examples in Inspection Manual Chapter (IMC) 0612, Appendix E, Examples of Minor Issues, but the inspectors determined this finding was more than minor because it affected the configuration control aspect of the Barrier Integrity cornerstone. Specifically, reactivity control and reactor manipulations are used to preserve the integrity of the fuel cladding in order to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. The inspectors used IMC 0609.04, Attachment 1, Phase 1 - Initial Screening and Characterization of Findings and determined the finding to be of very low safety significance (Green) because it did not affect the RCS barrier or the fuel barrier. This finding has a cross-cutting aspect in the area of Human Performance, Decision Making, where the licensee uses conservative assumptions in decision making and adopts a requirement to demonstrate that the proposed action is safe in order to proceed rather than a requirement to demonstrate that it is unsafe in order to disapprove the action.
