LONG TERM HABITABILITY OF TECHNICAL SUPPORT CENTER UNDER ACCIDENT DOSE ANALYSIS EXCEEDS ACCEPTANCE CRITERIA
"At approximately 1430 CDT on 3/12/08 Prairie Island staff completed a preliminary review of a revised dose analysis for the Prairie Island Technical Support Center (TSC) that called into question the long term habitability of the TSC under bounding accident conditions. The preliminary calculation result exceeds the 30-day 5 rem whole body dose acceptance criteria of NUREG-0696 and is based on bounding case assumptions consistent with Regulatory Guide 1.4 (including fuel melt, highest allowable containment leakage and bounding atmospheric dispersion factors). The primary contributor is an approximately 25 square foot window in the north wall of the TSC. Compensatory measures are being established to provide shielding over the window in the TSC."
The licensee will notify the NRC Resident Inspector.

AGREEMENT STATE - UNIDENTIFIED RADIOACTIVE MATERIAL RECEIVED AT METAL RECYCLING FACILITY
The State of Oregon Radiation Services Section reported that they had sent an inspector to Schnitzer Steel in Portland, Oregon due to unidentified radioactive material that had been received by the facility. A barge of metal for recycling had been received from Amix Recycling of Vancouver, British Columbia that set off a radioactive portal alarm. The radioactive material has not yet been specifically identified. The State inspectors have determined that one of the radioactive sources appears to be a process gauge with a Cesium source. There is also indication of a Radium or Cesium source in a scrap metal pipe. The State will ensure that the sources are adequately secured and will be following the licensees interactions with the originator of the shipment in terms of long term disposition of the sources.
Oregon Report Number 08-0025
* * * UPDATE AT 1921EDT ON 03/13/08 FROM STATE OF OREGON (TERRY LINDSEY) TO STEVE SANDIN VIA EMAIL * * *
"Oregon Radiation Protection Services personnel have completed an initial survey of the empty barge that contained two radiation gauges with Cesium-137. One gauge (mat scanner) was sheared apart with scrap steel equipment and was leaking along both shear points. Both gauges have been secured and contamination has been contained at this time.
"The Oregon 102nd Civil Support Team also assisted with the final survey and decontamination evaluation onsite and the site has been secured for today.
"A U.S. EPA Region X team has been activated by U.S. EPA Duty Officer and is enroute to Oregon to assist with further site evaluation and investigation. Oregon RPS personnel will be coordinating with the U.S. EPA team tomorrow morning for any final survey work and evaluation of potential enforcement concerns related to removal of radiation warning labels from these gauges."
Notified R4DO (Pruett) and FSME (Bradford).

INTERRUPTION TO ENS TELEPHONE SERVICE
"At 05:00 hours on 3/12/2008, it was discovered that the Surry Power Station Emergency Notification System (ENS) phone was nonfunctional. This was discovered when the NRC attempted to contact the Surry Main Control Room, and no response was obtained. The ENS phones in the Main Control Room and the Technical Support Center cannot dial out. Telecommunications has been contacted to investigate the problem.
"This event is reportable in accordance with 10CFR50.72(b)(3)(xiii), any event that results in a major loss of offsite communications capability. (e.g., Emergency Notification System).
"At 08:00 the NRC ENS phone was tested and it was determined to be functional from the Main Control Room to the NRC. The NRC Resident was notified that the ENS phone was returned to service at 09:20."

ACCIDENTAL EMERGENCY SIREN ACTIVATION
"At approximately 0815 CDT, on March 12, 2008, a Dakota County corrections officer inadvertently activated the Dakota County sirens from the backup unit during the conduct of a silent siren test. The licensee was notified of the siren activation by the activation signal received on the informer unit in the Technical Support Center (TSC) at 0815, as well as a subsequent phone call from the siren contractor. Seven of the 117 sirens in the 10-mile Emergency Planning Zone (EPZ) were activated for approximately 3 minutes. No press release is planned by Xcel Energy. Dakota Communications Center received a call from a local radio station asking why the sirens were activated. No other press release is planned by Dakota County.
"The NRC Senior Resident Inspector was notified."
