| Title | Technical Specification Violation |
| Event Description | On October 18th, 2016, the logarithmic channel was rendered inoperable when a ground wire became detached from the log pre-amp. This, in combination with the pre-amps close proximity to other electrical wires, created enough noise to make the log channel reading unreliable. The reactor was operated for over an hour before the malfunction was identified. At that point, the reactor was scrammed and secured. The compromised ground was discovered and replaced, and the pre-amp was placed on a platform away from the interference of the other electrical components. This log channel reading returned to normal, but operations were still suspended until the channel could be more thoroughly tested. A Corrective Action Report (CAR) was initiated. This is a violation of Technical Specifications 3.2.2, 3.2.3 and 4.2(e). This report to the NRC Operations Center is required by Technical Specification 6.2.2.
The licensee has notified the NRC Project Manager (Wertz). |
