Keywords:Strontium, Release, Transport, LWR severe accident

Release and transport behavior of Strontium (Sr) was evaluated by a combination method of atmosphere-dependent release model and chemical equilibrium calculation. It was found under a specific accidental condition that a meaningful amount of Sr could be released from the fuel and migrate and/or retain in the reactor.
