| Title | Emergency Sirens May Be Impacted By Extreme Weather Conditions |
| Event Description | The current NOAA weather forecast for the station is predicted to be about -25 degrees Fahrenheit [on the morning of January 9, 2010]. Based on this forecast, the station reviewed the impact of these temperatures on the 101 sirens in the Fort Calhoun Station 10-mile Emergency Planning Zone (EPZ). The siren manufacturer's and the FEMA approved siren design report information states that the sirens (Federal Signal model 2001) are designed for operation between the temperature readings of -22 degrees Fahrenheit and +140 degrees Fahrenheit.
Event Number 44782 and 44783, on a similar condition at another utility having the same sirens, were reviewed. It was noted that the reports documented discussion with the manufacturer's technical representative confirming that the sirens are operational and no special testing is required when the temperature goes below and then returns within the operating temperature limits. The current temperature at the station is within the operational limits. Therefore, the 101 sirens are considered functional at this time. The following agencies were notified that if the temperature falls below a negative twenty-two degrees Fahrenheit, the established process of back-up route alerting is to be used notifying the public in the event of a nuclear emergency where the sirens are activated but fail to respond: -Washington County, NE Emergency Management -Pottawatomie County, IA Emergency Management -Harrison County, IA Emergency Management This notification is being made in accordance with 10 CFR 50.72(b)(3)(xiii). No media press release is being made. The licensee has notified the NRC Resident Inspector.
A review of area temperature indicates that the siren design was not exceeded. The licensee will be notifying the NRC Resident Inspector. Notified R4DO (Hagar). |
