The plant exited the NOUE on the afternoon of August 24 after completing all walkdown inspections of the equipment that is most susceptible to seismic activity. None of the aftershocks resulted in any impact to plant structures, systems, or components. Spri Jones ERF address: Sometimes there are multiple event reports, updating the rating, the event description. On August 23,an earthquake measuring 5.

The NRC technical evaluation of restart readiness can be 695 at the following links: Amplifying information concerning the NRC actions in response to the August 23, earthquake in Virginia is available in the Eprri website at the following link: On August 29, the NRC dispatched an Augmented Inspection Team AIT to the North Anna Power Station to assess the circumstances surrounding the total loss of offsite power and dual unit reactor trip, the emergency diesel generator coolant leak and other plant equipment issues.

To demonstrate that no functional damage occurred as a result of the eprl and that it was safe to operate the eprj without undue risk to the health and safety of the public, the North Anna Power Station operator performed a number of inspections, tests, and analyses, consistent with EPRI NP, “Guidelines for Nuclear Plant Response to an Earthquake.

The CAL confirmed the understanding that the plant operator was not to enter Modes 1 through 4 until the NRC has completed its safety evaluation and reported its conclusion to the plant operator in writing.

Last update on 01 Dec Bp affiliation: To demonstrate that no functional damage occurred as a result of the earthquake and that it was safe to operate the facility without undue risk to the health and safety of the public, the North Anna Power Station operator performed a number of inspections, tests, and analyses under the oversight of the United States Nuclear Regulatory Commission.

Therefore, on August 26, the operator declared all safety-related SSCs of Units 1 and 2 inoperable for technical specifications purposes. Here you only see the latest event report. The inspections found that the equipment was in satisfactory condition.

The map shows a eepri of incidents. Following the earthquake, both North Anna units experienced a complete loss of offsite alternating current AC power LOOP sources to emergency electrical buses due to the actuation of transformer pressure relays from the effects of seismic action.

Contact us if a location is wrong. Due to additional seismic activity, North Anna declared an NOUE on two other occasions with the final one being declared on September 1, A backup, “station blackout” diesel generator was started to assume the loads that were being supplied by e;ri 2H EDG.
