They don’t bother to tell us what really happened here. It appears almost certain that it is a worker who was carried out on an emergency stretcher or gurney. Was this during the refuelling outage or during regular operations? One guesses it was during refuelling. Why does it say that both Unit 1 and Unit 2 temporarily lost secondary containment because doors were open? Do they share the doors? Is the NRC uncertain of which unit is impacted? Were there two emergencies? Is there some other reason? Will we ever know?
“REACTOR BUILDING AIRLOCK DOORS OPENED SIMULTANEOUSLY
“On April 6th, 2016 at 1337 [EDT] and 1343 [EDT] Secondary Containment became inoperable due to failure to meet a Surveillance Requirement (SR 22.214.171.124.3) on Unit 1 and Unit 2.
“The inoperability was caused when two separate sets of Reactor Building airlock doors were sequentially opened during a medical emergency to transport an individual. Each set of airlock doors was opened momentarily to allow passage.
“Secondary Containment was restored April 6, 2016 at 1344 [EDT] when the transport evolution was complete.
“This event is being reported under 10 CFR 50.72(b)(3)(v)(c) and per the guidance of NUREG 1022 Rev 3 section 3.2.7 as a loss of a Safety Function. There is no redundant Susquehanna Secondary Containment system.”
The NRC Resident Inspector has been notified.” http://www.nrc.gov/reading-rm/doc-collections/event-status/event/2016/20160407en.html

* Naval Hospital Camp Pendleton holds transport drills[MIGRATE]
Nov 18, 2013
CAMP PENDLETON, Calif. – Robert Miller and Chris Anderson roll a gurney into Naval Hospital Camp Pendleton during a patient relocation drill Nov. 15. Emergency medical technicians were escorted through the hospital to pick up corpsmen who posed as patients. The simulated patients were put into ambulances and transported to the new hospital, giving the participants a chance to experience what they will have to do during the actual relocation on Dec. 14. Miller and Anderson are both emergency medical technicians.
