| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text MISSING TRITIUM EXIT SIGN
The following information was received by e-mail:
"[The licensee] reported that during demolition work by their Maintenance Staff a wall with a tritium exit sign was demolished and the debris was removed from the facility.
The manufacturer of the sign is Safety Light. [The licensee] will investigate the model of the sign that was installed.
[The licensee] confirmed that the debris has left their facility as waste.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |

"At 0900 [EDT] this morning, Seabrook Station experienced leakage of approximately 200 gallons of untreated sanitary water to the storm drain system, which discharges to the circulating water system. Since Seabrook is not authorized to discharge untreated sanitary water, this event has been reported to the town of Seabrook and will be reported to the New Hampshire Department of Environmental Services and the Environmental Protection Agency. The preliminary apparent cause of the leak was a failure of the sanitary lift station discharge pumps to start automatically, which resulted in untreated sanitary water overflowing into the storm drain system. The leak was stopped by restarting the sanitary lift station discharge pumps. This event is being reported under 10CFR50.72(b)(2)(xi) for an event related to the protection of the environment for which notification to other government agencies has been or will be made."

"This is an eight hour report per 10 CFR 50.72 (b)(3)(xiii). Nine Mile Point is implementing a scheduled modification to reroute telephone cables as part of a planned Interim Spent Fuel Storage (ISFSI) modification. This rerouting will enable construction of the roadway to the ISFSI storage location and ensure no damage to telephone cables which currently pass through the roadway. The re-routing will ensure that no cabling important to control room and or TSC will pass under the roadway
"This work required that all Federal Telephone System (FTS) 2001 lines including Emergency Notification System (ENS), Health Physics Network (HPN) and Emergency Response Data System (ERDS) be removed for a period of approximately 1 hour.
"During the upgrade starts only 5 circuits were removed at a time and tested upon completion of re-routing. There was at least 2 alternate means of communication (via commercial telephone lines) continuously available.
"If an emergency had been declared during this period, the Control Room had the capability to make the notification to the offsite agencies using commercial telephone lines. The emergency preparedness communications procedure provides adequate instructions for use of these backup means. The Nine Mile Point procedures provide for alternate means of emergency assessment capability.
"All work associated with this modification was performed in an expeditious manner consistent with the goal of minimizing unavailability of the systems listed above. A test of all systems will be performed at the completion of the upgrade.
"All Control Room personnel have been briefed on this work and expected contingent actions.
"This job began on Monday, September 13, 2010 at approximately 1031 [EDT] and was completed at 1153 [EDT].
