The high level goal of the SMART-AS (Alarm System for System-integrated Modular Advanced ReacTor) is for operators to enthusiastically accept a new technology that will improve their response to alarms during plant transient conditions.Three alarm system design characteristics were included: (1) alarm processing(degree of alarm reduction); (2) alarm availability (prioritization and suppression); and (3) alarm display (a dedicated tile format, a mixed tile and message list format, and a format in which alarm information is integrated into the process displays).The SMART-AS prioritizes alarms based on the state of the plant; reduces the amount of information presented to the operator by grouping and display the arms in accordance with the present state of the plant; and allows nuisance alarms to be suppressed.This paper provides an introduction into applying the data mining techniques for the alarm processing of SMART-AS.In this paper, we describe our data mining algorithms, and illustrate how to apply these algorithms to generate an alarm suppression model from the alarm data.
