On September 27, 2012, Comanche Peak Nucle … On September 27, 2012, Comanche Peak Nuclear Power Plant began a cyber security related modification to the Unit 1 and 2 Plant Computer Systems (PCS) and associated network infrastructure. The entire PCS for each unit will be out of service for approximately 6 hours. During that time, the PCS satellite display systems (SDSs) in the TSC and EOF will be inoperable. After approximately 8 hours, the PCS will be restored to service along with the SDSs in the TSC. The SDSs in the EOF will remain out of service until the modification and related site acceptance testing is complete, currently scheduled for October 5, 2012. During this period. the remote display of Radiation Monitoring System (RMS) information in the EOF and OSC will be unavailable.</br>The loss of EOF SDS terminals will be compensated by use of an alternate plant parameter display system, and loss of EOF/OSC RMS remote display will be compensated by means of the status board recorder telephone loop. Therefore, it is expected that appropriate assessment of plant conditions. notifications, dose projections, and communications could still be made, if required, during the time that the SDSs and RMS remote displays are inoperable.</br>The extended loss of the EOF SDSs and EOF/OSC remote RMS data is being reported in accordance with 10.CFR.50.72(b)(3)(xiii). which is any event that results in a major loss of emergency assessment capability, offsite response capability, or off site communications capability. The NRC Resident Inspector has been notified. A follow-up ENS communication will be made when the EOF SDSs and EOF/OSC remote RMS remote displays are fully restored to service.</br>* * * UPDATE FROM RAUL MARTINEZ TO JOHN SHOEMAKER AT 0224 EDT ON 10/06/12 * * * </br>Maintenance has been completed on the Unit 1 and Unit 2 Plant Computer System.
