Not native English speaker, but current title ("Molten salt reactor claims melt down under scrutiny") is fairly clear that claims melt down, not the reactor. Apologies if the title has been changed since initial comments. Otherwise, probably the case of "mentally read beginning and end of sentence" :). [and yes, journalists seem to have love of puns and 'puns' that others can only groan at... my favourite in IT is of course The Register, which can raise a stink in the room just by listing the headlines;-]
