Axial enrichment profile in advance nuclear energy power plant at supercritical-pressures

Abstract

The High-Performance Light Water Reactor (HPLWR) is the European version of the advance nuclear energy power plant at Supercritical-pressure. A light water reactor at supercritical pressure, being currently under design, is the new generation of nuclear reactors. The aim of this study is to predict the HPLWR neutronic behavior of the axial enrichment profile with an average enrichment of 5 w/o U-235. Neutronic calculations are performed using WIMS and CITATION codes. Changes in neutronic parameter, such as Power Peaking Factor (PPF) are discussed in this paper.

Neutronic Analysis of Heavy Water Application in HPLWR Emergency Core Cooling System

“…Neutronic and Thermal hydralic analysis of HPLWR fuel assembly cluster has been performed by Tashakor et al [6,7]. Tashakor et al [8] presented an axial enrichment profile in advance nuclear energy power plant at supercriticalpressures. Neutronic analysis of semi-heavy water in VMHWR has been presented by Tashakor [9,10] , and the results show that use of semi-heavy water in VMHWRs coolant channels will lead to optimal fuel burn up and reactor performance.…”
