BOTH TRAINS OF CONTROL ROOM EMERGENCY AIR CONDITIONING SYSTEM INOPERABLE
"At 0628 [EDT] on 10/28/15, the Salem Unit 1 Control Room Emergency Air Conditioning System (CREACS) train was declared inoperable due to the results of charcoal filter testing not meeting the surveillance requirement. Prior to declaring the Unit 1 train inoperable, the system was operating in the single train filtration operation mode due to refueling outage activities being performed on Unit 2 with the Unit 2 CREACS train inoperable. This resulted in both units' CREACS trains being inoperable.
"Prior to the event on 10/28/15, Salem Unit 1 was operating in Mode 1 at 100% power and Unit 2 was in Mode 6 with fuel movement in progress.
"At 0628, Unit 1 entered Technical Specification 3.0.3, and Unit 2 suspended fuel movement to comply with Technical Specification 3.7.6 (Modes 5 and 6, or during movement of irradiated fuel assemblies), action c. The Unit 2 train was placed in service at 0755, allowing Unit 1 to exit Technical Specification 3.0.3. Operators continued to align the Unit 2 CREACS to single train filtration operation to comply with Unit 1 Technical Specification Action Statement 3.7.6.1, Action a. Actions to place the Unit 2 CREACS in single train filtration operation were completed at 0950.
"This 8 hour notification is being made pursuant to the requirements of 10 CFR 50.72(b)(3)(v) for 'any condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to : (D) Mitigate the consequences of an accident.'"
