Event Notification Report for June 12, 2008

ALERT DECLARED DUE TO TORNADO IMPACTING REACTOR BUILDING ONSITE

The research reactor building at the Kansas State University was damaged due to a tornado onsite. There is extensive damage to the building. The reactor was shutdown properly earlier in the day. There is no damage to the reactor. There is a loss of power onsite however, this type of reactor requires no active cooling. The reactor is shutdown and stable.

* * * UPDATE AT 0555 ON 6/12/08 FROM PAUL WHALEY TO PETE SNYDER * * *

The Alert condition at the site has been terminated. Conditions requiring entry into the Alert have been rectified.

Notified IRD (Gott), R4DO(Miller), EDO (Mallett), DHS (Jason Craig), FEMA (Mike LaForty), DOE (Thomas Yates), USDA (Rob Leadbetter), and HHS (Harry Peagler).

HIGH PRESSURE COOLANT INJECTION (HPCI) SYSTEM IDENTIFIED INOPERABLE DURING SURVEILLANCE

"Unit 2 HPCI was declared inoperable during the performance of a scheduled surveillance test. HPCI failed to develop the required discharge pressure to meet its design function." Reactor Core Isolation Cooling (RCIC) is available. The licensee notified the NRC Resident Inspector.

* * * UPDATE FROM DAVE FOSS TO JOHN KNOKE AT 0954 ON 06/17/08 * * *

"The purpose of this notification is to retract a previous report made on 6/12/08 at 0549 hours (EN# 44290). On 6/12/08, the High Pressure Coolant Injection (HPCI) system was declared inoperable as a result of the performance of a routine Surveillance Test (ST). During the ST, the HPCI pump discharge pressure did not achieve the acceptance criteria of greater than or equal to 1258 psig. The highest indicated pressure achieved during the ST was approximately 1230 psig. Therefore, notification of this issue to the NRC on 6/12/08 as a loss of the HPCI safety function was initially made as a result of the belief that the HPCI system was inoperable due to inadequate discharge pressure. HPCI was maintained in an available status as troubleshooting began.

"During subsequent troubleshooting on 6/12/08, it was determined that the Main Control Room HPCI discharge pressure indicator (i.e., the pressure indicator used during the ST) was reading approximately 65 psig low. Therefore, the pressure indicator used during the ST indicated a low value for discharge pressure. Based on this, the actual HPCI discharge pressure during the ST was acceptable. The pressure indicator was recalibrated and the HPCI ST was re-performed successfully. HPCI was declared operable by 1805 hours on 6/12/08.

"Based on the above, there were no unplanned loss of the safety function for the HPCI system. Therefore, the initial ENS notification is being retracted. "

Licensee has notified NRC Resident Inspector. Notified R1DO (Schmidt)

UNUSUAL EVENT DECLARED DUE TO A MAJOR LOSS OF RESPONSE AND COMMUNICATIONS CAPABILITY

"At 1130CDT on 6/12/2008, the Duane Arnold Energy Center was informed due to flooding in the local area that access to the Joint Information Center (JIC), the Offsite Radiological Analytical Laboratory (ORAL), the Offsite Relocation and Reassembly Area (ORRA), and the Emergency Operations Facility (EOF) have been lost. This constitutes a reportable condition per 10CFR50.72(b)(3)(xiii) due to the major loss of offsite response capability. The ORAL function will be maintained by the Iowa State Hygienics Lab. At the present time the remaining facilities are being relocated or moved to the Linn County Emergency Operations Center (EOC) located at the Kirkwood Community College Campus. Also, although multiple roads in the area are closed due to high water level, evacuation capability in the EPZ is being maintained. Also, at 1256CDT on 6/12/2008, Duane Arnold Energy Center was informed that local commercial phone service through the Palo phone system has been lost. This service also includes our ability to fax and access the internet. We have also lost our FTS2001 ENS connection. Again, per 10CFR50.72(b)(3)(xiii) this represents a major loss of offsite communication capability. Offsite communications is being maintained currently thorough our microwave and cell phone systems. Onsite communications are possible through our in house PBX and page system. Contingency plans are in effect to setup a mobile satellite uplink that would include voice and data capability."

The NRC Resident Inspector has been informed.

* * * UPDATE AT 1629EDT ON 06/12/08 FROM DOUG PETERSON TO S. SANDIN * * *

"At 1430CDT on 6/12/2008, Duane Arnold Energy Center lost communications capability via commercial phone line, FT2001 ENS system and the microwave phone system. This meets the threshold criteria of an EAL classification of an Unusual Event. At 1440CDT the Shift Manager declared that Unusual Event and notifications were made to Linn County Emergency Management Agency, Benton County Emergency Management Agency and the Iowa Homeland Security Emergency Management Division. Currently, offsite communication is still possible via our installed cell phone and satellite systems and onsite communications remain possible via our PBX and page system."

The NRC Resident Inspector has been informed. Notified ET Member (B. Mallet), all IRD Management (B. McDermott, W. Gott, M. Leach), Commissioners' Staffs (D. Skeen, T. Hipschman, S. Baggett, J. Thoma, D. Coe), EDO Staff (J. Adams), PAO (E. Brenner), OCA (D. Decker), RDOs (R. Summers, B. Bonser, P. Louden, G. Miller), FEMA, DOE, USDA, and HHS.


* * * UPDATE AT 1428EDT ON 06/19/08 FROM MARK GILBERT TO J. KNOKE * * *

"On 6/12/2008 at 1444 FPLE-DAEC declared an unusual event (SU6.2) due to loss of all offsite communication. These systems included the FTS 2001, microwave phone lines, and commercial phone lines due to flooding of the Palo, Iowa phone station. Since that date FPLE-DAEC has reestablished two of the three offsite communication methods. The microwave telephone system has been restored and the commercial phone lines have been restored through a new exchange through the town of Shellsburg, Iowa, which was not affected by the flood. With these two lines of offsite communications reestablished the DAEC will de-escalate from the Unusual event from the loss of offsite communication.

"FPLE-Duane Arnold will be issuing a press release stating the unusual event has been cancelled. The NRC senior resident inspector has been notified and the state of Iowa, Linn County, and Benton county will be notified."

The licensee exited the Unusual Event at 1428 EDT on 06/19/08. Notified R3DO (Kunowski), NRR EO (Fred Brown), IRD MOC (Bill Gott), DHS, and FEMA.

* * * UPDATE ON 7/1/08 AT 1640 FROM SCOTT AREBAUGH TO MARK ABRAMOVITZ * * *

Multiple power sources are now available to the Emergency Operations Facility.

The licensee notified the NRC Resident Inspector.

Notified the R3DO (Kozak).

UNAVAILABILITY OF EMERGENCY OPERATIONS FACILITY

"At 1345 on Thursday, June 12, 2008, the Cook Nuclear Plant (CNP) Buchanan Office Building was conservatively evacuated due to the presence of a solvent vapor in the building. The Buchanan Office Building houses both the Emergency Operations Facility (EOF) and Joint Information Center (JIC).

"The Buchanan Office Building has been ventilated and has been verified inhabitable by Safety and Health personnel. The Emergency Operations Facility and Joint Information Center access was restored at 1530 on Thursday, June 12, 2008. Further investigation concluded that the concentration of the solvent vapor was never at a level that would have mandated evacuation.

"This notification is being made in accordance with 10 CFR 50.72 (b)(3)(xiii) due to the loss of offsite response capability. The licensee notified the NRC Resident Inspector."
