"The implementation of a planned replacement of the Unit 3 plant process computer, also known as the Critical Function Monitoring System (CFMS), with a new Plant Integrated Computer System (PICS), resulted in the loss of the Emergency Response Data System (ERDS). The Meteorological Radiological Plant Data Acquisition System (MRPDAS), and Meteorological Information and Dose Assessment System (MIDAS) is also impacted. MIDAS will function but the automatic download of Unit 3 plant parameters will not be available and the MIDAS Operator (SM or Dose Assessor) will have to manually input this data to perform dose assessment. Meteorological data will remain available. All Unit 2 functions remain available. Other systems such as the Safety Parameter Display System (SPDS), the Radiological Emergency Communication System (RECS), and the Emergency Notification System (ENS) remain available. As a compensatory measure, a proceduralized backup method is available to FAX applicable data for ERDS and MRPDAS. As discussed in a letter to the NRC data October 6, 2010, the plant process computer is being replaced due to obsolescence. The new Unit 3 computer processors will be located in the Unit 2 Computer Room which will become the Computer Room for both the Unit 2 and Unit 3 Plant Computers. The new Unit 3 plant process computer work stations will be located in the Unit 3 Control Room. The new PICS was previously installed in the Unit 3 plant simulation facility. The modification was initiated on February 4, 2011 and is scheduled to be completed by March 6, 2011. The new PICS will not affect the transmitted data points nor affect the transmission format and computer communication protocol to ERDS. In accordance with the site reporting procedure, a loss of ERDS is reportable as a major loss of emergency assessment capability."
The licensee expects the duration of the ERDS outage to be from one to three weeks. The licensee notified the NRC Resident Inspector. The licensee also notified the following: New York State, Putnam County, Westchester County, Rockland County, and Orange County.
* * * UPDATE AT 0935 EDT ON 4/11/11 FROM CHARLES ROKES TO MARK ABRAMOVITZ * * *
"This notification is an update to the information previously provided on February 4, 2011. The replacement of the Unit 3 plant process computer with a new plant integrated computer system (PICS) has been completed. With the return of PICS to service the function of ERDS was also returned to service. A quarterly test with the NRC on April 5, 2011, verified ERDS is functional. The link to PICS for MRPDAS and MIDAS remains unavailable. The previously reported compensatory measure using a proceduralized backup method remains available to FAX applicable data for MRPDAS. Future upgrades will address the PICS data for MRPDAS and MIDAS."
The licensee notified the NRC Resident Inspector and will notify the state and local authorities.

The following information was provided by the State of Mississippi via e-mail:
"During inspection and review of licensee's gauge service reports, two gauges were discovered to have stuck shutters. Both gauges are Ronan models SA1-F37. Ronan service engineering was called in to repair gauges and determined that on gauge serial # 9473GG, the bottom bushing was found frozen to the shutter shaft. On gauge serial # M4122, the roll pin was broken and the shutter handle was rotated 45 degrees out of alignment. Both gauges were repaired.
Both gauges had a Cs-137 source. Gauge #M4122 was 5 millicuries and gauge #9473GG was 200 millicuries.

"On April 6, 2011 the Agency [State of Texas] was informed by the licensee that on April 6, 2011, while conducting shutter operational checks, the shutter on an Ohmart Model SH-F1 containing 60 millicuries of Cesium (Cs) -137 was found to be stuck in the open position. The licensee stated that this is the normal operating position for the gauge and because of its location it does not create an exposure risk to any individuals. The licensee has contacted a contractor to repair the gauge. The cause for the failure is under investigation. Additional information will be provided as it is received in accordance with SA - 300."

| Event Text AGREEMENT STATE REPORT - SOURCE DISLODGED FROM OHMART VEGA MODEL SHLM-BR
The following was received via e-mail:
"Licensee's RSO notified DRH [state] by phone on 3-22-11, and by letter received on 3-22-11, of a dislodged source from an Ohmart Vega Model SHLM-BR, fixed gauge Ser. No. 13530993. The source became dislodged from the main rod during the gauge's shutter test and fell into the gauge well. The licensee's surveys around the gauge well were less than 0.5 mR/hr. A gauge representative has been called in to repair the gauge.
"DRH [state] requested licensee send in manufacturer's service report with the licensee's written 30-day report."
The source is 40 millicurie Cs-137, ser. No. 6965GK.
Mississippi Incident Number MS-11004.
* * * UPDATE FROM JAYSON MOAK TO JOE O'HARA VIA E-MAIL AT 1200 EDT ON 4/7/11 * * *
"Licensee was contacted [by the state] on 4/7/11, for further clarification of the location of the source. The licensee's RSO said the source was at the bottom of the well inside a vessel. This would also be the case during normal operations. Surveys were also confirmed by the RSO to be 0.5 mR/hr around the vessel. Licensee's RSO said a new well is being built for the vessel and a service representative has been notified. Source retrieval and replacement of the gauge is scheduled for the middle of April once the new well is built, and the material in the vessel has cooled."

"An ambulance responded to the site to assist a worker with a head injury. The worker was transported as potentially contaminated to an offsite medical facility.
"Follow-up to the above information, it was later determined that the worker was not contaminated."
The contract worker was in secondary containment climbing a ladder when he hit his head on a scaffold pole. He was transported to Pottstown Memorial Hospital.
