Description

The 233Pa(2nth, f) cross-section has been experimentally determined for the first time using a fission track technique. It was found to be 4834 ± 57 b, which is significantly high and thus is very important for 232Th-233U-based fuel in advanced heavy-water reactors (AHWR) and accelerator-driven sub-critical systems (ADSs). This is because the 233Pa is an important intermediary in the thorium-based fuel cycle and thus its fission cross-section is a key parameter in the modeling of AHWR and ADSs. The 233Pa(2nth, f) cross-section was calculated theoretically using the TALYS computer code and found to be in good agreement with the experimental value after normalization with respect to 241Am(2nth, f).
