Title	Reportable Occurance Related to Building Exhaust Fan
Event Description	The following information was provided by the licensee via fax or email: While performing the pre-start checkout on 2022-02-15 [at approximately 0800 EST], the SRO [Senior Reactor Operator] performing the checkout discovered that the building exhaust fan was not operating. This fan is required to be operating during reactor operations, and it is typically left running all the time. Troubleshooting determined that the cause of the fan loss was power loss from a conduit being cut the previous day when a small area of the cement floor in the janitor closet was being removed for replacement of the janitor closet sink. The concrete work was performed between 1200 and 1453 EST, which was when the contractor signed in and out. The reactor was shut down at 1551 EST, so the reactor was operated for at least an hour without the fan operating. There were no safety implications for the reactor, the staff, or the public.
