>it is an opinion piece written by someone who has a very specific viewpoint.

whether a core melts through the containment vessel or not depends on specific temperature that pool of melted uranium on the floor will develop. That in itself depends on the geometrical shape of the pool, uranium enrichment degree and presence of the neutron moderator material in the pool. That in itself depends on a bunch of other things ...

Nowhere it depends on the opinion or a viewpoint.
