Texas A&M welcomes uranium conversion research
The Texas A&M Engineering Experiment Station (TEES) has signed a research agreement with Quantum Leap Energy (QLE) “to advance and de-risk the commercial production of high-purity uranium hexafluoride (UF6).”
QLE is an Austin, Texas–based subsidiary of ASP Isotopes (ASPI), which is developing an isotope enrichment platform for applications in nuclear energy, nuclear medicine, and semiconductors. QLE specializes in the uranium conversion step of the nuclear fuel cycle—the conversion of yellowcake uranium concentrate (U3O8) into UF6 prior to enrichment.

The Transient Fission Matrix Combination (TFMC) method is a novel hybrid algorithm that performs transient neutron transport calculations with high fidelity and computational efficiency. In this paper, we verify the TFMC method using the control rod insertion/withdrawal C5G7-TD benchmark. The TD4 test case involves five complex control rod movement patterns in a four-assembly light water reactor model. On 20 parallel cores, each 16-s transient simulation completes in approximately 2 min (excluding database generation time). The computed total power and power distributions agree closely with reference results in all cases. These findings demonstrate the TFMC method’s potential as an efficient and accurate tool for transient neutron transport simulations.
