Abstract

ABSTRACT
This research is on performing computational analysis of Criticality Accident Alarm System (CAAS). It is focused on the parts of the standard that are most, applicable to calculating CAAS detector response and evaluating CAAS detector coverage. This is followed by a brief discussion of how CAAS detector response calculation differs from eigenvalue calculations that criticality safety practitioners perform regularly. This research provides computational
example how to determine the minimum accident of concern according to ANSI/ANS-8.S-1997 (R2012), how to calculate the response of a CAAS detector due to a specific criticality accident, and how to evaluate the coverage of a CAAS detector for criticality accidents. These researches are solved applying SCALE 6, but the methodologies can be applied to other radiation transport codes with the similar capabilities, including deterministic codes.

ABSTRAK
Kajian ini adalah berkaitan dengan analisis berkomputer Sistem Penggera Kemalangan Kritikal. Ianya difokuskan di bahagian kebiasaaan yang kebanyakan dapat, dikaitkan untuk mengira tindak balas pengesan CAAS dan menilai liputan pengesan CAAS. Ini diikuti oleh satu perbincangan ringkas bagaimana pengiraaan sambutan pengesan CAAS pengiraan berbeza dari pengiraan-pengiraan nilai Eigen yang boleh diaamalkan oleh pengelidik keselamatan kritikal. Penyelidikan ini menyediakan contoh pengiraan bagaimana untuk menentukan kemalangan minimum, berdasarkan ANSI / ANS 8.3 1997, bagaimana untuk menghitung sambutan pengesan CAAS disebabkan kemalangan kegentingan khusus, dan bagaimana unt.uk menilai, liputan pengesan CAAS untuk, kemalangan-kemalangan, kegentingan. Penyelidikan ini, menggunakan SCALE 6, tetapi, kaedah, lain boleh digunakan ke atas kod pengangkutan sinaran lain kod dengan keupayaan serupa,, termasuk, kod-kod deterministik.
