"During the current Unit 2 refueling outage, the Unit 2 plant process computer system will be taken out of service for approximately three weeks to support a planned modification which will install a new (upgraded) plant process computer system. During this timeframe, ERDS [Emergency Response Data System] and SPDS [Safety Parameter Display System] will be unavailable on Unit 2 which will remain in a shutdown condition. The computer outage will have no impact on Unit 1. Should the need arise, plant status information will be communicated to the NRC using other available communication systems. The computer outage is expected to commence at 1130 CDT on 3/17/2010 and the process computer will be restored prior to Unit 2 startup, currently scheduled for 4/11/2010.
"This event is reportable under 10 CFR 50.72(b)(3)(xiii) as a Major Loss of Assessment Capability."
The licensee has notified the NRC Resident Inspector.

| Event Text AGREEMENT STATE - RADIOGRAPHY TRUCK INVOLVED IN AUTO ACCIDENT
"On April 7, 2010 at approximately 1430 CST the Incident Investigation Program was notified by the licensee's Radiation Safety Officer (RSO) that one of the licensee's trucks carrying a camera with a 24 curie Iridium (Ir) 192 source had been involved in a car accident around 1300 CST that same day. The RSO stated that the radiography truck had collided head on with a tractor-trailer on a highway approximately 8-10 miles east of Kosse, Texas. One of the radiographers was fatally wounded and the other was rushed to the hospital. Consequently, no one was able to perform a survey to verify the source was intact in the camera as well as secure the camera. The RSO stated that the Robinson County Emergency Management Coordinator was on the scene along with police and fire personnel, as well as Texas Department of Transportation. The RSO stated that none of the emergency personnel responding were equipped with a radiation survey meter to verify the source locale. The RSO stated that the Site Radiation Safety Officer was en route to the scene to perform a survey and retrieve the camera, but he was almost two hours away. The Emergency Management Coordinator had cordoned off the area around the radiography camera. I contacted an Agency investigator who was near the area performing field work, and he agreed to go by the location and perform a survey because he could be there within 45 minutes. At approximately 1630, the investigator arrived on the scene and performed his survey. The investigator stated that it appeared the source was still housed in the camera and that the highest dose rate was 2.2 millirems/hour near the camera. The site RSO arrived on the scene, and the investigator briefed him on the survey. The information was passed to the RSO and he agreed to submit a report to the Agency."

| Event Text AGREEMENT STATE - DEPLETED URANIUM FOUND IN SCRAP METAL
A scrap yard located in Seguin, TX was processing a rail car loaded with scrap metal when their radiation detectors alarmed. When the load was investigated a Varian Linear Accelerator was found (serial number 71). The source of radiation was determined to be from approximately 100 lbs. depleted Uranium contained in the unit.
The shipment originated from Austin, TX.
* * * RETRACTION FROM RAY JISHA TO CHARLES TEAL ON 4/8/10 AT 1302 * * *
Additional investigation determined that the Varian CLINAC 18 accelerator does not contain depleted Uranium. The shields in this model are made of tungsten. |

"At 1622 hours CDT, an electrical ground on 480 Volt Bus 1B3A was determined to be from a supply cable to Motor Control Center (MCC)-3A1. Isolating loads on this MCC required securing power to HCV-1385, Steam Generator RC-2B Inlet Isolation Valve. This condition results in the valve being unable to close on a Steam Generator Isolation Signal (SGIS), which requires entry into Technical Specification 2.0.1(1). This Technical Specification requires the plant to be placed in a Hot Shutdown condition within 6 hours. A plant shutdown to Mode 3 was commenced at 1740 hours CDT."
The licensee notified the NRC Resident Inspector.
* * * UPDATE FROM DAVID SPARGO TO DONALD NORWOOD AT 0036 EDT ON 4/9/2010 * * *
"At 2123 hours CDT, the Reactor was manually tripped from 22% Reactor Power in order to meet the requirements of Technical Specification 2.0.1(1) and have the reactor in a hot shutdown condition. All systems functioned properly.
"At 2124 CDT, the plant entered Mode 3 Shutdown Condition. AT 2235 CDT, HCV-1385, Steam Generator RC-2B Inlet Isolation Valve has been manually closed. Technical Specification 2.0.1(1) has been exited."

"On April 10, 2010, the Monticello Nuclear Generating Plant (MNGP) will be performing planned maintenance to upgrade the site phone system. The maintenance activity will result in the majority of commercial phone lines to the site and the onsite phone system being taken out-of-service for approximately two hours starting at approximately 0800 CDT. The site NRC Emergency Telephone System (ETS), phone lines (which includes ENS, HPN, and ERDS), auto ring lines between the site and the State of MN Emergency Operations Center, onsite radio communication systems, offsite radio communications systems, and the plant Gaitronics system will be unaffected by the maintenance activity. In addition, a commercial phone line in the Control Room and dedicated cellular phone for the Shift Manager will be available for off-site communications."
The licensee notified the NRC Resident Inspector and will notify state and local agencies.

"At 04:00 on Monday, April 12, 2010, the Cook Nuclear Plant (CNP) Technical Support Center (TSC) air conditioning and charcoal filtration systems will be removed from service for scheduled maintenance. Under certain accident conditions the TSC may become unavailable due to the inability of the air conditioning and charcoal filtration systems to maintain a habitable atmosphere. Compensatory measures exist to relocate TSC personnel to the unaffected unit's control room if necessary.
"TSC ventilation system maintenance is scheduled to be completed by 22:00 on Monday, April 12, 2010.
"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 of an emergency response facility." |

"A planned modification at the James A. Fitzpatrick (JAF) Nuclear Power Plant will replace an air conditioning chiller unit located in the old administration building. The electrical isolations necessary to safely perform the modification will require tagging out a booster fan common to the chiller unit and the Technical Support Center (TSC) ventilation system. Therefore, the TSC ventilation system will be rendered non-functional during the course of the work activities. The TSC ventilation is expected to be out of service for approximately 12 hours.
"If an emergency is declared requiring TSC activation during this 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 station Emergency Plant Manager will relocate the TSC staff to an alternate TSC location in accordance with applicable site procedures giving first consideration to the Control Room. TSC facility leads have been made aware of this contingency.
"This notification is being made in accordance with 10CFR50.72(b)(3)(xiii) due to the potential loss of an emergency response facility (ERF). An update will be provided once the TSC ventilation has been restored to normal operation.
"The NRC Resident Inspector has been notified." | |
