Event Reports: Earthquake felt on-site at Arizona nuke, Fitness for Duty failures in Pennsylvania and Tennessee, alarm failure reported in Illinois and high winds felt at Iowa nuke

Some items from this week’s Events Notification Report page on the Nuclear Regulatory Commission’s website:

1. On Saturday night, Arizona’s Palo Verde nuclear power declared an Unusual Event after an earthquake was felt on-site. The shaking was the result of a 5.2 magnitude earthquake near Safford, Arizona. A subsequent walk-down showed no damage, and the emergency was terminated after about two hours.

The earthquake was at roughly the mid-point of a string of nuclear facilities that stretch from Palo Verde to the Los Alamos National Laboratory to the Waste Isolation Pilot Plant to the Waste Control Specialists’ low-level radioactive waste dump near Andrews, Texas. The stretch from Los Alamos to WCS is sometimes referred to as the nation’s Nuclear Mega-Mall.

2. On June 27, a licensed operator at the Beaver Valley nuclear power plant in Pennsylvania was found to be in violation of the plant’s Fitness for Duty policy. No further details were included in the report, nor was it specified whether the operator’s site access has been suspended or terminated.

3. On Wednesday, the Watts Barr nuclear plant in Tennessee reported that a non-licensed supervisor had tested positive for alcohol in a random test. The supervisor’s site access has been terminated.

4. The Braidwood nuclear power plant in Illinois reported that two sirens failed to function during a thunderstorm on Tuesday. The report says that the failure “resulted in the loss of the capability to alert a large segment of the population.” The two defective sirens have been repaired.

5. And the Duane Arnold nuclear plant in Iowa reported that wind during a thunderstorm Monday briefly exceeded the velocity that should have prompted an Emergency declaration. One sensor on-site clocked winds at 95.5 miles per hour. A review of the readings prompted an “After the Fact Emergency Declaration.”
