Fission yield measurements for decay heat evaluation of used nuclear fuel

Corpuscular physics and outer space Nuclear physics

Abstract

The fission process involves the violent splitting of a heavy nucleus into two fission fragments, resulting in over 300 different isotopes. Understanding the distribution and production of these fragments, known as fission yields, is essential for grasping the underlying mechanisms of fission, which are influenced by nuclear structure and dynamics. Accurate measurements of fission yields are crucial for advancing nuclear energy applications, particularly in developing Generation IV reactors and recycling spent nuclear fuel. The VAMOS magnetic spectrometer enables precise fission yield measurements due to its large acceptance and identification capabilities for various isotopes. An experimental campaign at VAMOS in 2024 utilized beams of (^{238})U and (^{232})Th on a carbon target to produce fissioning actinides. The combination of VAMOS with a new Silicon telescope (PISTA) enhances data quality significantly. The candidate will analyze VAMOS data to produce high-resolution fission yields and study uncerta
