| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text TEN TRITIUM EXIT SIGNS STOLEN FROM CONSTRUCTION SITE
The following information was received via fax:
"Hotel under construction in Ft. Lauderdale, FL. Ten exit signs containing tritium were stolen. Owner contacting police and is searching for items. No further action will be taken on this incident."
The exit signs are general licensed material, model number SLXTURW10, manufactured by Forever Light, Inc. Each sign contains 7.09 Curies tritium. The signs were installed Saturday, 7/28, and noticed missing yesterday, 8/1.
Florida Incident No.: FL07-116
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. |

"This 4-hour notification is being made to report that Salem Unit 2 has experienced an automatic reactor trip. The trip was initiated by a low steam generator level on 22 SG (14 percent narrow range). The low steam generator level was apparently caused due to the feedwater regulating valve closing as a result of a spurious 'Feedwater interlock' signal. Post trip the following occurred: 21, 22, & 23 auxiliary feedwater pumps auto started after the trip due to valid steam generator low levels (14 percent) as expected on a unit trip. 23 Auxiliary feedwater pump [turbine driven] was tripped in accordance with the emergency operating procedure and will be returned to an operable condition following recovery of steam generator levels.
"Salem Unit 2 is currently in mode 3. Reactor coolant system pressure at 2235 psig and temperature is 547 degrees F with decay heat removal via the main steam dump system. Unit 2 has no active shutdown Tech Spec Action statements in effect.
" There was no major secondary equipment tagged for maintenance prior to the event."
On the reactor trip, all control rods fully inserted. No primary or secondary relief valves or safety valves lifted. The electric plant is in a normal shutdown lineup. This event had no effect on Unit 1.
The licensee notified the NRC Resident Inspector. The licensee will notify the Lower Alloways Creek township, the State of NJ Bureau of Nuclear Engineering, and the State of Delaware. The licensee also plans on issuing a press release. | |
