"This is a non-emergency eight hour notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) as the discovered condition affects the functionality of an emergency response facility.
"A condition impacting functionality of the TSC Ventilation system was discovered on October 15, 2015 at 1554 EDT. The issue involved a loss of heating capability of the TSC Ventilation system due to failed ventilation system components. The review of the impact of this equipment failure on the habitability of the TSC over the 30 day mission time determined that this condition was reportable as a loss of emergency assessment capability. The repair of the equipment failure is currently being planned.
"If an emergency is declared requiring TSC activation during the non-functional period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC becomes uninhabitable due to ambient temperature, radiological, or other conditions. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to an alternate location in accordance with applicable site procedures. This condition does not affect the health and safety of the public or station employees.
"The NRC Resident Inspector has been notified."
* * * RETRACTION ON 11/12/2015 AT 1453 EST FROM JOHN CAVES TO MARK ABRAMOVITZ * * *
"Subsequent calculations determined that the loss of heating capability of the TSC Ventilation system did not affect the TSC functionality at the time of discovery or during the 30 day mission time period. Therefore, the TSC remained functional throughout the time in question.
"The initial 10 CFR 50.72(b)(3)(xiii) report is being retracted. The NRC Resident Inspector has been informed of this notification retraction."

| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - MISSING EXIT SIGNS
The following was received from the State of Colorado via email:
"After no response from the annual mailing to register active general licensee's in our radioactive materials unit, a public record search was conducted to discover the owner of the property. Research disclosed from county records the homeowner's name and contact address. He was mailed a letter on 9/2/15. The exit signs were from the manufacturer Isolite Corporation. Isolite provided Glasco Electric, 700 W Mississippi Avenue Denver, CO 80223, the exit signs that were designated to be used at 5744 N 71st Street, Longmont, CO 80223. The two (2) exit signs were model # 2040-50G-20WH, activity 11.5 Ci, serial numbers were not recorded on the manufacturers quarterly report dated 10/1/2001 to 12/31/2001.
"A response was received from the home owner. He provided the following information: The Association for Community Living occupied 5744 N 71st Street, in Longmont, CO 80503 at the time the exit signs were shipped. According to the historical information, the building was used as a school for the developmentally disabled. The school closed and the property was sold in 2013. The new owner began renovation of the property and removed the exit signs. The owner reported local city codes requires all deconstruction materials to be recycled. He took the exit signs to The Center for Resource Conservation located in Boulder, CO during the calendar year of 2014. The home owner was unaware of any regulations pertaining to the use or disposal of Tritium exit signs.
"The Center for Resource Conservation was contacted 11/4/15 to inquire about the exit signs possibly being at the location 6400 Arapahoe Road, Boulder, CO 80303. Management explained upon materials being dropped off the donor is given a receipt for the donation showing items donated. When large boxes are inspected smaller items may not get noticed and slip through the donation lane. Items are separated and maybe placed in a recycling roll off to be picked up by Evraz located in Denver, CO. It is unknown when they would have accepted the exit signs in 2014. It is unknown if the exit signs were resold or scrapped. No further information is available."
Event Report ID No.: CO15-I15-29
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.

"At 0826 CST on 11/11/2015, 1R-22, Shield Building Vent Gas Radiation Monitor, was removed from service for planned maintenance. This monitor has no compensatory measure that will allow timely classification of two Emergency Action Levels (EALs) - NUE (Notification of Unusual Event) and Alert classifications - when out of service. It is also used for offsite dose projection calculations. This results in a Loss of Emergency Assessment Capability while 1R-22 is out of service. This is a reportable condition in accordance with 10 CFR 50.72(b)(3)(xiii).
"Unit 1 Shield Building Ventilation Stack is also monitored by high range monitor, 1R-50, which is used for the same purpose in Site Area or General Emergency classifications. 1R-50 is being monitored and is indicating normal values. There are no radioactive leaks that will impact the Shield Building as evidenced by normal readings on 1R-22 prior to its removal from service. The duration of this maintenance is scheduled for 24 hours and will continue until the monitor is returned to service. Maintenance will not result in the unplanned release of radioactivity to the environment and will not adversely affect the safe operation of the plant or health and safety of the public.
"The licensee has notified the NRC Resident Inspector."
* * * UPDATE AT 1547 EST ON 11/12/15 FROM PAUL FINHOLM TO JEFF HERRERA * * *
The licensee indicated that the duration of maintenance was extended for approximately 24 hours to allow continued repair of the monitor.
The NRC Resident Inspector was notified.

"At 1132 hours [EST] on November 12, 2015, Susquehanna Steam Electric Station Unit 1 reactor automatically scrammed due to one Main Steam Isolation Valve (MSIV) unanticipated closure causing a High Pressure RPS [Reactor Protection System] trip.
"All control rods inserted and both reactor recirculation pumps tripped due to reactor water level 2. Reactor water level lowered to -37 inches causing Level 3 (+13 inches) and level 2 (-38 inches) (Division 2 only) isolations. RCIC [Reactor Core Isolation Cooling] automatically initiated and was overridden by control room operators after RPV [Reactor Pressure Vessel] water level was restored to the normal band with feedwater. All isolations and initiations occurred as expected. No main steam relief valves opened. Pressure was controlled via main turbine bypass valve operation. All safety systems operated as expected.
"The Unit 1 reactor is currently stable in Mode 3. Investigation into the cause of the MSIV closure is underway.
"Unit 2 was unaffected and continues power operation.
"The NRC Resident Inspector has been notified. A voluntary notification to PEMA [Pennsylvania Emergency Management Agency] and press release will occur."
The plant is in its normal shutdown electrical lineup. |

"On November 12, 2015 at 1132 hrs. [EST], Secondary Containment became inoperable due to failure to meet SR 3.6.4.1.1 requirements on Unit 2.
"The inoperability was caused when RB [Reactor Building] Zone II differential pressure [D/P] oscillated between 0.23 and 0.43 inches WG [water gauge] (less than SR 3.6.4.1.1 requirement of greater than or equal to 0.25 inches WG). The oscillations subsided at 1501 [EST] and RB Zone II D/P continues to be maintained at approximately 0.35 inches WG.
"This event is being reported under 10 CFR 50.72(b)(3)(v)(c) and per the guidance of NUREG 1022 Rev 3 section 3.2.7 as a loss of a Safety Function. There is no redundant Susquehanna Secondary Containment system."

"On 11/12/2015 at approximately 1500 EST, a spill to the environment was determined to be reportable to the state environmental and local health agencies. A press release is planned.
"The spill occurred when a portable chemical toilet tipped over and was identified at approximately 1440 EST. The contents and exact quantity of the spill are unknown but the toilet has a capacity of 60 gallons. The spill contacted the ground but did not reach any waterways. Cleanup efforts are in progress.
