| Title | Loss Of Ens Phone Circuits And Some Commercial Communication Capability |
| Event Description | At 2200 CDT on 7/13/09 it was discovered the Emergency Notification System (ENS) phone lines in the Unit 1 and Unit 2 control rooms and the Technical Support Center were not functioning. Additionally, the Health Physics Network is not functioning. This discovery occurred during extent of condition troubleshooting when it was determined that local cellular phone and land-line phone service was unavailable in some local areas. A successful land-line phone call to the NRC Operations Center was completed following this discovery, All State and local authorities required to be contacted in the event of an Emergency Class declaration were contacted via land-lines and made aware of the situation.
Also at this time, the Dedicated Emergency Fax/Voice System (DEF/VS) is unable to fax to the Arkansas Department of Health (ADH) Little Rock Operations Center. Land-line voice communications to Little Rock have been verified. The Russellville ADH office is able to receive fax notifications from ANO and can ensure that all state and local agencies can be notified. The Russellville ADH office will remain manned until the situation is resolved. At approximately 2345 CDT, it was determined that the NRC Operations Center was unable to directly contact either Unit 1 or Unit 2 control room. The cause of the loss of communications is suspected to be a major fiber-optic line being cut In Morrilton, Arkansas. No estimate of time for repairs Is available at this time. The licensee has established that communication capability exists via either radio or phone with local emergency response and law enforcement organizations. The licensee can still contact the NRC via commercial circuits but cannot receive calls from the NRC. A dedicated cell phone line has been established by the licensee to facilitate communication from the NRC if necessary. State and local authorities have been informed of the problem. The NRC Senior Resident Inspector has been notified and has responded to the site.
