Reactor Containment Heat Removal by Passive Heat Sinks Following a Loss-of-Coolant Accident

Laminar and turbulent condensation models have been employed to compute the heat transfer coefficients on the heat-conducting surfaces following a loss-of-coolant accident in a reactor containment. The results indicate significantly higher heat transfer coefficients than those predicted by the modified Tagami correlation, and consequently the post-blowdown containment peak pressure reduces considerably.
