"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"

At 1905 EST, Vermont Yankee declared a Notice of an Unusual Event (NOUE) based on EAL SU 4.1, loss of 75% of the control room annunciators associated with safety related systems for greater than 15 minutes. Around 1845 EST, several annunciators were received and based on the failure mode, the licensee conservatively estimated that greater than 75% of the annunciators in the control room were inoperable.
The licensee will notify the NRC Resident Inspector.
