| event text = Beginning December 1,2009, at approximately 1200, the Fermi 2 Integrated Plant Computer System (IPCS) will be removed from service to support installation of a Cyber Security Modification. The Safety Parameters Display System (SPDS) and Emergency Response Data System (ERDS) reside on the PCS platform and will be out of service when the PCS is removed from service. These systems will be unavailable to the Control Room and all other Emergency Response Facilities (ERFs) for approximately six hours. By 1800, it is planned to restore IPCS, including SPDS and ERDS, to the Control Room, Operational Support Center, and the Technical Support Center. The IPCS will remain unavailable to the Emergency Operations Facility (EOF) as well as alternate EOF. On December 2, at approximately 1600, IPCS will be restored to the EOF but will remain unavailable to the alternate facilities. On December 3, 2009, at approximately 1600, IPCS will be restored, including alternate facilities. | | event text = Beginning December 1,2009, at approximately 1200, the Fermi 2 Integrated Plant Computer System (IPCS) will be removed from service to support installation of a Cyber Security Modification.

During this entire duration dose assessment capability will only be available in the manual data input mode. A follow-up notification will be submitted when the PCS is completely restored. For the first six hours of the PCS outage, the emergency assessment capability of all Fermi 2 ERFs will be degraded by the loss of IPCS and SPDS. During this period the ERDS function will also be lost. For the following 24 hrs., the EOF will have no IPCSs capability, which includes the SPDS function. Based on the aggregate effect of these losses, this notification is being made per the requirements of 8 Hour Non-Emergency Notification 10CFR,50.72(b)(3)(xiii), any event that results in a major loss of emergency assessment capability. | During this entire duration dose assessment capability will only be available in the manual data input mode.
