Thermal-hydraulic analysis of cross-shaped spiral fuel in high power density BWRs
… analysis of the cross-shaped spiral (CSS) fuel assembly suggests great thermal-hydraulic upside. According to computational models, the increase in rod surface area, combined with an increase in coolant turbulence and inter-channel mixing will allow for a greater than 25% uprate in total …

Thermal aspects of high efficiency channel with conventional and alternative fuels in SuperCritical water-cooled reactor (SCWR) applications
… range of 45 ‒ 50% owing to reactor‘s high outlet temperatures. A generic pressure-channel (or pressure-tube)SCWR operates at a pressure of 25 MPa with inlet- and outlet-coolant temperatures of 350°C and 625°C. Consequently, the sheath and fuel centerline temperatures are higher in SCWRs than those …

Design of an economically optimum PWR reload core for a 36-month cycle
… an economic benefit. On the other hand, fuel with higher enrichment is required, and the fuel fabrication costs go up. A single-batch strategy is required if the current burnup licensing limit (60 GWD/MTU) is to be maintained. Previous work has shown the technical feasibility of …
