| Title | Licensee-Identified Violation |
| Description | The inspectors reviewed a Severity Level IV problem consisting of two non-cited violations committed by an instrumentation and control technician for attempting to readjust a potentiometer to its original position without proper documentation and failing to notify the control room of a plant status control error. Technical Specification 5.5.1.1.a requires procedures to be established, implemented, and maintained covering the applicable procedures recommended by Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Regulatory Guide 1.33, Quality Assurance Program Requirements (Operation), Appendix A, Typical Procedures for Pressurized Water Reactors and Boiling Water Reactors, Section 1.c, includes typical safety-related activities that should be accomplished in accordance with written procedures, such as equipment control. Procedure SO123-XV-15 , Maintaining Plant Status Control, Section 6.4.1 requires that plant manipulations are only made via an approved tracking document and Section 6.6.1 requires that the Shift Manager must be informed of any actual or suspected plant status control error. Contrary to the above, on March 28, 2011, plant manipulations were made without an approved tracking document and the Shift Manager was not informed of an actual plant status control error. Specifically, an Instrumentation and Control technician manipulated the Channel A potentiometer without an approved tracking document and failed to notify the Shift Manager of the plant status error. This was entered into the licensees corrective action program as NN 201393301. The licensee subsequently verified the operability of both Channels A and B and took actions to prevent potential cross-train errors for future instrumentation and control work. This violation is being treated as a non-cited violation in accordance with Section 2.3.2 of the NRC Enforcement Policy because the licensee identified the violation and promptly reported it to the NRC; it was an isolated action of an employee in a low level position without management involvement; it was not caused by a lack of management oversight; and, the licensee took appropriate remedial action commensurate with the circumstances. |
