The following was received via email from Westinghouse:
On July 25, 2020, at approximately 1100 EDT, a Westinghouse employee performing routine work in the pelleting area passed out due to a personal medical emergency. Site emergency first responders responded per plant procedures and training until Emergency Medical Services (EMS) personnel arrived. The employee was transported to an offsite medical facility accompanied by a plant health physics technician due to the potential for radioactive contamination based on the work location of the employee.
There was no release to the environment and no process or plant equipment involved. Surveys taken at the hospital and of all emergency response equipment and response personnel revealed no contamination. [All removable contamination from the Westinghouse employee was returned to the facility.] The Columbia plant is a licensed Part 70 facility subject to 10CFR70 Subpart H.
The licensee has notified state and local county governments.
