The implementation of a planned replacemen … 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.</br>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.</br>* * * UPDATE AT 0935 EDT ON 4/11/11 FROM CHARLES ROKES TO MARK ABRAMOVITZ * * *</br>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.
