The event tree for a (fictitious) safety system in a natural gas reactor is designed to prevent damage from hydrogen released due to a rupture or leakage. The possible outcomes are: • An explosion • A jet fire • A flash fire • Gas released harmlessly Given the Event Tree below and the values associated with each event, what is the probability that there is either a Flash Fire or a Jet Fire once the initiating event has occurred? Give the answer to 4 decimal places. Event Probability of "Yes" to event occurring Instantaneous release 0.013 Immediate ignition 0.019 0.03 Delayed ignition Explosion of fire 0.065 Initiating Instantaneous release Event Immediate ignition Delayed ignition Explosion Incident Outcome or fire YES Explosion YES NO Jet fire YES YES Explosion YES NO Flash fire NO Hydrogen Release (leakage /Rupture) Gas release (Harmless) YES Flash fire YES YES Explosion Gas release (Harmless) NO Gas release (Harmless)
