UNAVAILABILITY OF TSC VENTILATION SYSTEM AND CHARCOAL FILTER FOR SCHEDULED MAINTENANCE
"At 0445 on Monday, October 6, 2008, the Cook Nuclear Plant (CNP) Technical Support Center (TSC) ventilation system and charcoal filter was removed from service for scheduled preventive maintenance. The charcoal bed filtration system is also out of service in support of the maintenance on the TSC ventilation system.
"Under certain accident conditions the TSC may become unavailable due to the inability of the filtration system to maintain a habitable atmosphere. Compensatory measures exist to relocate TSC personnel to the unaffected unit's control room if necessary based upon results of procedurally required monitoring of TSC radiological conditions.
"The TSC ventilation system maintenance is scheduled to complete at 16:00 on Monday, October 6,2008.
"The licensee has notified the NRC Senior Resident Inspector.
"This notification is being made in accordance with 10 CFR 50.72 (b)(3)(xiii) due to the loss an emergency response facility."

"The TSC Ventilation System and Charcoal Filter was returned to functional status at 14:35 on Monday, October 6, 2008.
"This follow up notification is being made to provide closure from the initial notification under 10 CFR 50.72 (b)(3)(xiii) due to the loss of an emergency response facility."
The licensee has notified the NRC Resident Inspector. Notified R3DO (Lara).

TEXAS AGREEMENT STATE REPORT- SOURCE RETRACTOR FAILED TO FUNCTION
The following information was received from the State of Texas via e-mail:
"While servicing the level gauge [Ohmart Model A2102, Cs-137], an Ohmart technician discovered that the source retractor failed to function. The source is extended into a polymer vessel and is functioning normally while source is extended. Ohmart will recover the source and remove it from service. The licensee will arrange for disposal and discontinue use of the source."
Texas Report I-8570.
* * * UPDATE ON 11/7/2008 AT 1138 FROM ART TUCKER TO MARK ABRAMOVITZ * * *
This report from the state of Texas was received via e-mail:
"The licensee provided the Agency with a report on the investigation they conducted into the cause for the failure of the source to retract into the source holder on November 4, 2008. That report provided the following information.
"The gauge has been in place on the vessel since 1998. It appears that the source has not been retracted back into the source holder in a number of years. The source well is three feet deep and the total clearance between the source and the well wall is 0.322 inches.
"The source well is in a section of the vessel that contains a very thick, almost hardened, polymer material. The vessel was initially used to contain a polymer slurry, but the vessel's use was changed shortly after start up. This change resulted in the hardened polymer to form in the vessel. These actions all took place prior to the current owner taking possession of the facility.
"The licensee had tried to retract the source back into the source holder, but it only moved a distance of between 12 and 18 inches before it became stuck. The manufacturer's technician was able to move the source back to the end of the source well. This is the normal position for the source. It is believed that the weight of the polymer over the years has caused the well to bow to a point where it now limits the movement of the source.
"The licensee intends to remove and dispose of the source during a scheduled outage in 2009. The gauge is located at a height of 12 feet above grade. Dose rates taken at a height of 8 feet indicate a dose rate of 0.01 to 0.1 millirem per hour.
"Additional information regarding accessibility and occupancy of this area has been requested by the state."
Notified the R4DO (Campbell) and FSME (Suber).

UNEXPECTED REACTOR CORE ISOLATION COOLING ISOLATION DURING TEST
"During performance of PNPS Procedure 8.M.2-2.6.3 Attachment 1 step (65) the RCIC System isolated on a Group 5 signal when relay contact blocking devices (boots) were removed. All isolations went to completion. This isolation was not part of the planned evolution.
"The Group 5 isolation was reset and RCIC was placed in stand by line-up at 2327 on 10/6/2008. Investigation is continuing."
The licensee notified the NRC Resident Inspector.
