The fundamental design of the cold-neutron source (CNS) to be installed in the China Advanced Research Reactor (CARR) was prepared. The principal design criterion of the fundamental CNS design is the maximum increase of cold-neutron flux considering nuclear heating to be removed and safety problem. All nuclear calculations were performed with MCNP (version 4A) computer code using a complete 3D model of a reactor core and CNS except a horizontal cold-neutron channel. The nuclear heating, integral cold- and thermal-neutron flux and cold-neutron gain factor were evaluated for all options. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 3]
