Using Sea Water as an Alternative Emergency Coolant to Enhance Nuclear Safety
报告人: 潘钦 教授 台湾清华大学
Nuclear power, with its low carbon nature, is a very effective measure to reduce global worming emissions. Enhancement of nuclear safety is one of the major issues to broaden the acceptance of nuclear power. In fact, the Taipower Company in Taiwan has proposed the Ultimate Response Guideline (URG) to deal with a Fukushima-like accident and natural sea water around the nuclear power plant may eventually be employed to cool the reactor.
This talk will present some of our recent studies on the quenching of hot objects, up to 1000 °C, in natural sea water and compared with that in de-ionized water. The rapid quenching in natural sea water demonstrates the beneficial side of using natural sea water as an alternative emergency coolant to enhance the safety of a nuclear power plant.
Dr. Pan is now a Tsing Hua distinguished professor of National Tsing Hua University. He is now Chief Principal Investigator (Director) of the Low Carbon Energy Center, a center of excellence at NTHU funded by the Ministry of Education through the “Plan to Develop World-Class Universities and Top-Notch Research Centers”.
Dr. Pan’s research activities for the past two decades have been in the areas of two-phase flow, boiling heat transfer and energy engineering with a special focus on transition boiling, nucleate boiling near CHF, nuclear reactor thermal hydraulics, two-phase flow instability with or without nuclear coupling, two-phase natural circulation loops, microchannel two-phase flow, microchannel boiling, microchannel heat sink, microchannel reactor, and thermal-fluid transport in fuel cell systems.
