The nuclear industry needs more and more computing power to meet the myriad challenges it faces. While today's supercomputers will be inadequate in a few decades, quantum computing is generating considerable interest and hope.
As a key component of the energy mix, the nuclear industry faces innumerable challenges when it comes to maintaining its current role and preparing itself for the future. The most pressing need for the existing plants is to reduce their costs. For atomic energy to remain competitive, we estimate that it needs a cost reduction of around 30%.
There are various ways to achieve this. Behavioral simulation opens up new scenarios to optimize the safety and efficiency of operations by providing technicians with information and predicting the behavior of plant equipment with unparalleled accuracy and completeness. Augmented reality means they can act more quickly, more efficiently, and with greater safety, in perfect coordination with the control room. The use of data to better control production, or to apply planning and 5D design, enables maintenance and construction operations to be optimized.
Based on the Internet of Things, 3D, Big Data, artificial intelligence, and complex simulation, these kinds of operational applications require computational power that was only available for research until recently.
Computation at the heart of the nuclear industry
The development, industrial validation, and construction of new generation reactors, such as small modular reactors (SMR), high and very high temperature reactors (HTR, VHTR), and rapid neutron reactors (RNR) require ever greater computing power for modelling and simulation.
While nuclear research and the nuclear industry are already among the first to use High Performance Computing (HPC), and the CEA (Commissariat à l’énergie atomique) has some of the most powerful supercomputers in the world, all of these new developments will only increase demand at an exponential rate. However, conventional IT is already reaching its limits. The traditional race for computing power, which is primarily a race for miniaturization, is approaching the insurmountable wall of atomic scale. The sector is also very attentive to the development of quantum computers, which should allow this limit to be exceeded, as well as exponentially multiplying performance for certain algorithms.
Quantum, beyond high performance computing
Quantum computers are based on subatomic physical objects (qubits) with states that can encode binary information. The big difficulty is managing to intertwine and stabilize these qubits to obtain the equivalent of a processor. Qubits form unstable structures, weakened by so-called "decoherence" phenomena. To date, researchers have successfully stabilized twenty qubits in an operational setting and fifty in an experimental setting. The systems known as Noisy Intermediate-Scale Quantum (NISQ) tolerate certain disturbances and can display 50 to 100 qubits whose short periods of stability are sufficient to perform certain operations. Generally, quantum calculators are not necessarily destined to become general-purpose computers. They serve as accelerators for certain calculation sections or deal with specific problems for which they are particularly suitable, such as n-body problems or combinatorial optimization.
Of course, both of these are of great interest to the nuclear industry! In research, being able to simulate dynamic systems with strongly correlated n-bodies would be a decisive step forward to help improve our understanding of this question. As for combinatorial problems, they are a key issue for the industry, similar to the optimization of shutdowns. So, it is hardly surprising that the US Department of Energy (DOE) is among the first customers of the Atos quantum QLM simulator, or that the CEA is launching an industrial research post, focusing in particular on developing more robust qubits. From atom to atom, the nuclear industry and quantum computing are walking into the future hand in hand.
