Abstract
Thorium-based fuel bundles according to one or more embodiments of the present invention provide a fresh fuel bundle comprising a first ring of fuel pins and a second ring of fuel pins. Each ring fuel pin has a fuel composition comprising uranium and thorium. The first ring fuel pins differ from the second ring fuel pins in each of the thorium wt %, uranium wt %, and 235U enrichment.
Claims21
A fresh fuel bundle comprising a first ring of fuel pins and a second ring of fuel pins, wherein:
- each of the first ring fuel pins and the second ring fuel pins have a fuel composition comprising uranium and thorium;
- thorium wt % of the fuel composition in each of the first ring fuel pins differs from a thorium wt % of the fuel composition in each of the second ring fuel pins;
- uranium wt % of the fuel composition in each of the first ring fuel pins differs from & uranium wt % of the fuel composition in each of the second ring fuel pins;
- 235U enrichment of the uranium in each of the first ring fuel pins differs from 235U enrichment of the uranium in each of the second ring fuel pins;
- the thorium wt % of the fuel composition in each of the first ring fuel pins and in each of the second ring fuel pins is less than or equal to 90 wt %;
- the uranium wt % of the fuel composition in each of the first ring fuel pins and in each of the second ring fuel pins is at least 10 wt %;
- the 235U enrichment of the uranium in each of the first ring fuel pins and in each of the second ring fuel pins is less than or equal to 20%;
- and
- the fuel bundle is shaped and configured to be used in a pressurized heavy water reactor.
