| Title | Potential Violation of Technical Specifications |
| Event Description | Technical Specification 3.2.3 requires two (2) channels of reactor period and reactor level are functional during work involving reactivity being moved in the core. In this case an experiment was being moved into the core and performing some blade testing. The reactor was shutdown at the time with all prior required tests competed satisfactorily. Upon completion, it was discovered that one of the period channels alarm function required by TS was disconnected.
The licensee implemented corrective actions to prevent recurrence. A conference call was established with the licensee and NRR (Adams, Quichocho and Sloan). |
