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 • Ajet fire • A flash fire • Gas released harmlessly Given the Event Tree below and the values associated with each event, what is the probability that gas is NOT released harmlessly once the initiating event has occurred? Give the answer to 4 decimal places. Event Probability of "Yes" to event occurring Instantaneous release 0.020 Immediate ignition 0.016 0.05 Delayed ignition Explosion of fire 0.051

Initiating Event Instantaneous release Immediate ignition Delayed ignition Explosion or fire Incident Outcome YES Explosion YES NO Flash fire YES YES Explosion YES NO Flash fire NO NO Gas release (Harmless) Hydrogen Release (leakage /Rupture) YES Jet fire NO YES Explosion YES NO Flash fire NO NO Gas release (Harmless)
