SUMMARY
The discussion centers on the feasibility of using liquid nitrogen injection as a cooling method for molten reactor cores in the event of a catastrophic breach at the Fukushima plant. Participants highlight the impracticality of this approach due to the immense thermal output of the reactors, which would require an unmanageable amount of liquid nitrogen—approximately 20 tanker trucks per hour for four reactors. The conversation also touches on the challenges of constructing circum containment systems around the reactors, given the geological constraints and the current state of the reactor pressure vessels. The INES 7 rating indicates severe risks, yet the reactors' pressure vessels remain intact, complicating the situation further.
