Development of Methodology to Assess Application of Practical Elimination for Nuclear Power Plants

摘要

The Fukushima Daiichi nuclear accident is presented as the primary case study for the topic of practical elimination. A decision matrix was created to assess whether practical elimination has been achieved or not. Public acceptance is included as a factor in practical elimination. An evaluation of an underground High-Temperature Gas Cooled Reactor was performed, where it was determined that a greater than 10 earthquake on the Richter scale is practically eliminated, but can easily be overturned based on public acceptance. A plane crash scenario was also practically eliminated. The gap analysis performed concluded that the developed decision matrix requires reworking.
