1 Mar 2018 Oak Ridge - Nuclear scientists at Oak Ridge National Laboratory (ORNL) are retooling existing software used to simulate radiation transport in small modular reactors, or SMRs, to run more efficiently on next-generation supercomputers. In addition, Oak Ridge National Laboratory researchers have directly written high-purity metallic structures narrower than a cold virus - which could open nanofabrication opportunities in electronics, drug delivery, catalysis and chemical separations.

ORNL is working on various aspects of advanced SMR designs through simulations currently performed on the lab's Titan supercomputer.

"The next generation of supercomputers will run on more sophisticated architectures based predominately on graphics processing units, or GPUs", ORNL's Steven Hamilton stated. "For the radiation transport algorithms to be compatible, we are preparing now so that we can take advantage of the full capability of GPU-based systems and run simulations as efficiently as possible."

The ORNL team leveraged Titan's hybrid platform system that includes GPUs to develop and test the radiation transport codes. The newly developed method, described in Annals of Nuclear Energy , will be further scaled up to run larger simulations efficiently when future machines come online.

At ORNL's Center for Nanophase Materials Sciences, the team rastered a beam from a helium-ion microscope through a solution to locally deposit platinum, forming a ribbon only 15 nanometers in diameter.

"This is the first occurrence of direct-write nanofabrication from a liquid-phase precursor using an ion microscope", stated ORNL's Olga Ovchinnokova. "With full understanding from experiment and theory, we direct-wrote precise structures with highly pure material using unique tools."

The team ran calculations on ORNL's Titan supercomputer and analyzed data from experiments and simulations to understand the dynamic interactions among ions, solids and liquids essential for optimizing the process. Their results were published in the journal Nanoscale .
