dc.description.abstract | This paper presents the development of a nodal diffusion code, RAST-V, and its verification and validation for VVER (vodo-vodyanoi energetichesky reactor) analysis. A VVER analytic solver has been imple-mented in an in-house nodal diffusion code, RAST-K. The new RAST-K version, RAST-V, uses the triangle -based polynomial expansion nodal method. The RAST-K code provides stand-alone and two-step computation modes for steady-state and transient calculations. An in-house lattice code (STREAM) with updated features for VVER analysis is also utilized in the two-step method for cross-section gen-eration. To assess the calculation capability of the formulated analysis module, various verification and validation studies have been performed with Rostov-II, and X2 multicycles, Novovoronezh-4, and the Atomic Energy Research benchmarks. In comparing the multicycle operation, rod worth, and integrated temperature coefficients, RAST-V is found to agree with measurements with high accuracy which RMS differences of each cycle are within +/- 47 ppm in multicycle operations, and +/- 81 pcm of the rod worth of the X2 reactor. Transient calculations were also performed considering two different rod ejection sce-narios. The accuracy of RAST-V was observed to be comparable to that of conventional nodal diffusion codes (DYN3D, BIPR8, and PARCS).(c) 2022 Korean Nuclear Society, Published by Elsevier Korea LLC.
