Event Description	The Plant Process Computer System (PPCS) will be taken out of service for an approximate 2 week period to implement a planned modification. The current PPCS is being replaced and the computer outage is required to allow cutover to the new PCCS. During this time period ERDS and SPDS will not be available. Also, a small portion of the plant annunciator system (Trouble Light Alarms) will not be available. Regulatory Guide 1.97 Category 2D Containment Temperature and Category 3D Component Cooling Water Temperature indicators will not be available in the Control Room, although other instrumentation is available to monitor these parameters. This is an 8-hour reportable event per 10 CFR50.72(b)(3)(xiii) Major Loss of Assessment Capability. The operation of plant systems will not be affected due to this planned action. ERDS and SPDS parameters will be monitored by control board indications. Compensatory actions have been developed. The PPCS outage is expected to commence around 0700 CST on 1/6/05.
