SAMI, a physical model and computer code for FCI in a LMFBR subassembly

SAMI is a physical model with corresponding computer code. It describes a fuel-coolant interaction in a LMFBR subassembly. The model takes into account the multichannel geometry of the subassembly and assumes a partial meltdown of the fuel. The computer code gives the possibility of variating initial conditions and system parameters such as channel sizes and number. The present paper is a description of the computer code and how to use it
