DEGRADED CONDITION DUE TO LEAKAGE ON A PRESSURIZER HEATER SLEEVE
During in-service inspection VT-2 visual inspection, the licensee discovered dried boric acid on pressurizer heater sleeve C-3. All other pressurizer sleeves were inspected with no additional findings. The licensee will not increase coolant temperature until the repair is made to the sleeve.
The licensee has notified the NRC Resident Inspector.

OPERATIONS SUPPORT CENTER RENDERED NON-FUNCTIONAL DURING PLANNED MAINTENANCE
"Planned preventive and corrective maintenance activities are being performed today (2/25/08) on the Hatch Nuclear Plant's HP/Chemistry area emergency air handling unit. The HP/Chemistry area emergency HVAC is required for functionality of the Operations Support Center (OSC), as this area may be utilized during declared emergencies. These planned work activities are to be completed today within (15) hours. During the time these activities are being performed, the HP office emergency HVAC will not be available for operation and will be rendered non-functional during the performance of the work activities.
"If an emergency condition requiring activation of the OSC occurs during the time these work activities are being performed, then contingency plans call for continued utilization of the HP/Chemistry areas as long as radiological conditions allow. Habitability surveys will be performed more frequently in the areas while they are being utilized. If required, respiratory protection equipment will be utilized, as appropriate, for emergency responders utilizing this area until such time as the power is restored to allow the HP/Chemistry emergency HVAC to be returned to service.
"This event is reportable per 10 CFR 50.72 (b)(3)(xiii) as described in NUREG-1022. Rev. 2, since this work activity affects an emergency response facility for the duration of the evolutions."
The licensee has notified the NRC Resident Inspector.
