Summary of the MACCS and COSYMA Consequence Codes

Introduction

The information developed in this study will be used to perform uncertainty studies 
using the European Commission (EC) consequence code COSYMA and the US
Nuclear Regulatory Commission (USNRC) code MACCS. COSYMA and MACCS 
model the offsite consequences of postulated severe reactor accidents that release a 
plume of radioactive material to the atmosphere. These codes model the transport and 
deposition of radioactive gases and aerosols into the environment and the potential 
resulting human health and economic consequences. They calculate the health effects, 
impact of countermeasures and economic costs of the releases. The processes 
considered in the calculations, and the routes of exposure following accidental 
releases to atmosphere, are illustrated in Figure A-1. The calculations are divided 
into a number of steps, illustrated in Figure A-2. COSYMA and MACCS are modular 
codes, with different modules addressing the different stages of the calculation. 
However, while Figure A-1 illustrates the steps in the calculation, the modules of 
the codes do not correspond exactly with the boxes shown.

The following sections give brief descriptions of the COSYMA and MACCS codes.
