| Event Text ABNORMAL OCCURRENCE DURING MOVEMENT OF A REGULATING BLADE
On Jan 09, 2017, during movement of a reactor regulating blade, an expected annunciator did not occur. This required entry into Technical Specification 3.2.F.8. The rod run in relay and contact block were replaced and the system tested satisfactorily. Technical Specification 3.2.F.8 was subsequently exited.
The licensee will be notifying the Research and Test Reactor Project Manager. |

"This notification is a 10 CFR 21.21(a)(2) interim report for power supply model N-2ARPS-A6. Two instrument power supplies for the 'B' Residual Heat Removal (RHR) system were being bench tested prior to installation when it was discovered that they failed to meet Vendor Technical Manual specifications for voltage stability for varying loads. The deviation was a voltage drop of approximately 300mV. This did not meet the specification of less than 150mV when varying current from 5 amps (full load) to 2.5 amps. A second replacement power supply exhibited a similar 300 mV drop.
"James A. FitzPatrick (JAF) reviewed the work order instructions to determine if there was a deviation from the recommendations in the Foxboro technical manual F180-0309 Spec 200 Multinest Power Supply 2ARPS Series calibration. Since as-found voltage readings were within the required tolerance of the RHR instrument loops, the power supplies appear to have been capable to perform their intended function. However, this evaluation did not troubleshoot why the power supplies failed to meet the calibration requirements.
"The power supplies were sent to a repair vendor. The input from this vendor is expected to allow JAF to complete the evaluation per 10 CFR 21.21(a)(1) by March 21, 2017, and a notification for failure to comply or defect per 10 CFR 21.21(d)(3)(i) is expected by March 24, 2017, if necessary. This notification is being submitted as an interim report per 10 CFR 21.21(a)(2)."

"On January 10, 2017, at approximately 2040 EST, a spill to the environment was determined to be reportable to state environmental and local health agencies. A press release is planned.
"The spill occurred when a portable chemical toilet tipped over and was identified at approximately 2040 EST. The quantity of the spill is estimated to be five gallons. The spill contacted the ground but did not reach any waterways or storm drains. Cleanup efforts are in progress.
"The licensee has notified the NRC Resident Inspector." | |
