A roadmap has been established for development of ATW Technology. The roadmap defines a reference system along with preferred technologies, which require further development to reduce technical risk, associated deployment scenarios, and a detailed pl
Actinide-Only Burnup Credit for Pressurized Water Reactor Spent Nuclear Fuel—I: Methodology Overview
Publikováno v:
Nuclear Technology. 125:255-270
A conservative methodology is presented that would allow taking credit for burnup in the criticality safety analysis of spent nuclear fuel (SNF) packages. The method is based on the assumption that the isotopic concentration in the SNF and cross sect

A flat, uniform axial burnup assumption, preferred for its computational simplicity, does not always conservatively estimate the pressurized water reactor spent-fuel-cask multiplication factors. Rather, the reactivity effect of the significantly unde

The calculation of isotopic concentrations in spent nuclear fuel (SNF) assemblies and the subcritical multiplication factor of SNF packages are two of the essential requirements of the actinide-only burnup credit methodology. To justify the accuracy

In this paper, uranium metal alloys were previously suggested for use in advanced pressurized water reactors; a method is proposed to select an appropriate fuel rod diameter for a uranium alloy-fueled reactor. The method attempts to isolate effects c
