T 6.0 EXERCISE SCENARIO
^
6.1 Narrative Summary "The ' cenario begins with a contaminated injury s
requiring of fsite medical assistance.
This results in the declaration-of a Notification of Unusual Event.
While the contaminaten injury is being transported to Maryvale Samaritan'~Aospital, a dropped rod accident occurs and the rod recovered.
However, the flux tilt caused by the rod drop casualty results in fuel cladding failure.
An Alert is declared due to an increase on the Letdown Monitor of greater than 1% fuel failures within a 30-minute period.
While awaiting confirmatory chemistry results, a rod ejection accident occurs.
A Site Area Emergency is declared as the loss of coolant becomes greater than make-up pump capacity.
The reactor is tripped.
The Power Access Purge Downstream Isolation Valve fails to close when a containment isolation signal is received.
An uncontrolled fire involving the turbine lube oil storage tanks occurs requiring offsite fire assistance.
The casualty is escalated to a General Emergency when the failure of the Power Access P. urge Upstream Isolation Valve results in a release to atmosphere with levels greater than SR/hr (Thyroid) at the site boundary.
The release path is terminated by an emergency repair of the Power Access Purge Downstream Isolation Valve.
Due to releases of radioactive materials to the environment, radiation monitoring teams will be deployed.
The~ scenario also incorporates medical and fire emergencies requiring offsite assistance.
News media participation is expected and.both APS and state media centers will be activated.
Exchange of information among the various public information spokespersons will facilitate joint releases to the news media.
