If it's not interesting from an engineering perspective then why did the nuclear community write a post-accident report [1] and then update it 7 years later [2]? Perhaps _now_ it's less interesting as the faulty design has been studied at least twice with computer simulations (and a lot more skepticism on the initial Russian presentation which blamed the operators).
