2/22/2016· The cost of most reactors can be estimated by determining the cost of a pressure vessel with the same dimensions and adding in the cost of the internals (Towler and Sinnott, 2013). ... as it is the most economical method for large scale reactors. Chemical agents cannot be toxic to the product, and UV radiation cannot penetrate fluids easily.

Large-Scale Simulations, Large Eddy Simulation, Exascale, CFD 1. INTRODUCTION Computational fluid dynamics (CFD) is increasingly used to simulate nuclear reactor flows. Most CFD analysis, especially within industry, relies on the Reynolds averaged Navier-Stokes (RANS) approach and traditional two-equation turbulence models.

Location. Currently, nuclear power stations are large scale sites that typically cover an area of over 400,000m2. This is because traditionally once a company has gone through the time and expense of securing an appropriate site, it was more cost effective to build as much capacity on that site as possible.

SMRs are predicted to have higher fuel costs than large reactors. Particularly, integral pressurized water reactors (iPWRs) are shown to have from 15% to 70% higher fuel costs than large light water reactors using 2014 nuclear fuels market data. Fuel cost sensitivities to reactor design parameters are presented.
