LOSS OF THE OPERATIONS SUPPORT CENTER DUE TO INOPERABLE EMERGENCY HVAC
"During the performance of procedure 34S0-Z41-006-0 section 7.3.1.8, which tests the operability of the HP/CHEM area emergency HVAC, the system failed to indicate proper flow of the system. On panel 1Z41-N030, the system flow gauge failed upscale high and could not be lowered. The decision was made to halt the procedure at 1700 [EDT] on step 7.3.1.8 and restore the normal HP/CHEM HVAC lineup.
"The HP/CHEM area emergency HVAC is required for functionality of the Operations Support Center (OSC), as this area may be used during declared emergencies. Alternate OSC facilities have been verified to be available. All efforts and resources have been made available to restore the HP/CHEM emergency HVAC to functional status.
"This event is reportable per 10CFR50.72(b)(3)(xiii) and TRM 3.10.1.B.2"
The licensee has notified the NRC Resident Inspector.
