N2 - We developed a new transport lattice code called DENT-2D (Deterministic Neutral Particle Transport Code in 2-Dimensional Space). This code is designed to generate few-group constants for the reactor physics analysis diffusion code such as KAERI reactor analysis nodal code, MASTER, and to perform a whole-core transport calculation. CASMO-3 and HELIOS have been used in generating the few-group constants for MASTER. DENT-2D adopts characteristics method for the spatial discretization, CMFD (Coarse Mesh Finite Difference) for the speedup of eigenvalue calculation, subgroup method for the resonance treatment, B1 approximation for the criticality spectrum, and exponential matrix method for the depletion calculation. We performed benchmark calculations for the fuel assemblies of pressurized water reactor and compared results with those of the conventional reference codes such as CASMO-3, HELIOS and MCNP4C. The results show that the multiplication factors of DENT-2D are consistent with HELIOS within 100 pcm for the single pins and within 200 pcm for the assembly. The reactivity changes from the changes of fuel and moderator temperatures are also very consistent with each other. Pin power distributions predicted by DENT-2D are very close to those of HELIOS code. The multiplication factors as a function of burnup are also consistent with those of HELIOS and CASMO-3.
