An inverted pressurized water reactor design with twisted-tape swirl promoters
… to increase the core power density by using twisted tapes (TTs) as swirl flow promoters inside the IPWR cooling channels. The study focuses on optimizing the cooling channel design with twisted tapes to improve the DNB performance alongside using more powerful reactor coolant pumps to deliver …

Departure from nucleate boiling and pressure drop prediction for tubes containing multiple short-length twisted-tape swirl promoters
… possibility of inserting multiple short-length twisted-tapes (MSLTTs) in the cooling channels. For a fixed coolant mass flow rate, the swirling flow produced by the MSLTTs allows the IPWR to have a higher operating heat flux while maintaining the design criteria of MDNBR as compared to either …

Investigation and characterization of pressure drop in evenly spaced twisted tapes
… Ferroni (2010) suggested using short-length twisted tape inserts in order to increase the critical heat flux (CHF) at which departure from nucleate boiling occurs. Shortlength twisted tapes were proposed in his study because they offer the benefits of increased heat transfer and CHF, but also …

Computational fluid dynamics modeling and comparison of advanced techniques for heat transfer augmentation for nuclear applications
… feature of NuScale’s reactor designs. Twist tape is one passive heat enhance heat technique. The present research investigated thermo-hydraulic characteristics of natural and forced convection of water under different configurations of twisted tape inserted in tube as well as NuScale rod …
