Verification of the nTRACER/CTF code system for full core high resolution cycle analysis with the OECD/NEA TVA Watts Bar Unit 1 benchmark

• Development of the high-resolution multi-physics core solver nTRACER/CTF for cycle analysis of PWRs. • Verification of nTRACER/CTF with VERA for the OECD/NEA TVA Watts Bar Unit 1 benchmark. • High-resolution simulation of the whole first cycle of OECD/NEA TVA Watts Bar Unit 1 benchmark with nTRACER/CTF. • Good agreement of the two code systems in terms of Boron Concentration, pin power and local temperature predictions. This study aims to develop and verify the multi-physics high-resolution coupled code system nTRACER/CTF for full core depletion calculations in Cartesian geometry. The verifications are conducted on the basis of the OECD/NEA TVA Watts Bar 1 benchmark (TVA WB1), using multi-physics high-resolution results from the Virtual Environment for Reactor Applications (VERA), which includes MPACT and CTF. The paper presents the development of the nTRACER/CTF coupled system for dep…
