Abstract
Abstract
The equipment number of Small module reactor (SMR) is significantly less than that of commercial reactor, and accordingly, the number of fixed fire ignition sources and the ignition frequency are much less. Based on the analysis of the design characteristics of Small Module Reactor, this paper develops a preliminary research and innovation on the internal fire ignition frequency evaluation method of Small Module Reactor, and implements a sensitivity analysis on the commercial reactor ignition frequency methods. The result indicates the fire ignition frequency would increase 51% if the NUREG/CR-6850 generic ignition frequency data are adopted. However, the design characteristics of SMR can be better reflected in this innovative method, which needs more attention in the future.
