“…Beyond the realm of traditional safeguards, RETINA-type systems have also been proposed for disarmament negotiations and plutonium disposition. A recent study has argued for their deployment in Russian fast reactors tasked with eliminating plutonium stockpiles 29 . Studies have also investigated how they can be used to monitor MOX burnup in a PWR to verify plutonium incineration 30 .…”

Employing antineutrino detectors to safeguard future nuclear reactors from diversions

The Non-Proliferation Treaty and other non-proliferation agreements are in place worldwide to ensure that nuclear material and facilities are used only for peaceful purposes. Antineutrino detectors, sensitive to reactor power and fuel changes, can complement the tools already at the disposal of international agencies to safeguard nuclear facilities and to verify the States’ compliance with the agreements. Recent advancement in these detectors has made it possible to leverage them to reduce the likelihood of an undetected diversion of irradiated nuclear material. Here we show the sensitivity of antineutrino monitors to fuel divergence from two reactor types: a traditional light-water reactor and an advanced sodium-cooled reactor design, a likely candidate for future deployment. The analysis demonstrates that a variety of potential diversion scenarios can be detected by such a system. We outline recent developments in monitoring capabilities and discuss their potential security implications to the international community.

For over 40 years, physicists have considered possible uses for neutrino detectors in nuclear nonproliferation, arms control, and fissile materials security. Neutrinos are an attractive fission signature because they readily pass through matter. The same property makes neutrinos challenging to detect in systems that would be practical for nuclear security applications. This colloquium presents a broad overview of several potential neutrino applications, including the near-field monitoring of known reactors, far-field monitoring of known or discovery of undeclared reactors, detection of reactor waste streams, and detection of nuclear explosions. We conclude that recent detector advances have made near-field monitoring feasible. Farther-field reactor detection and waste stream detection monitoring are possible in some cases with further research and development. Very long-range reactor monitoring and nuclear explosion detection do not appear feasible for the foreseeable future due to considerable physical and/or practical constraints.

“…Recent work has shown that neutrino detectors, both using IBD (i.e.ν e capture on free protons) and CEνNS on nuclei, can serve as novel state of the art instruments for monitoring nuclear facilities (see [227] for a review). This includes both civilian nuclear reactors, where precise measurements of theν e flux can provide information about spent fuel [228,229], and the global excess of fissile nuclear materials [230,231]. These ideas have already motivated the construction of one such neutrino-based nuclear reactor monitoring system [232].…”

“…In both cases, CEνNS occupies a unique and complementary position relative to IBD because of its thresholdless nature [231,233]. There are two ways in which CEνNS differentiates itself from IBD.…”

“…Perhaps more important, however, is the fact that certain neutrino flux components appear only below the IBD threshold, E ν 1.8 MeV, and so CEνNS is the only tool available for certain applications. A notable example is the monitoring plutonium blankets [231] as a marker of compliance with the Plutonium Management and Disposition Agreement. 12 Interestingly, it is in this low-energy, low-nuclear recoil limit…”

We calculate coherent elastic neutrino-nucleus scattering cross sections on spin-0 nuclei (e.g. 40Ar and 28Si) at energies below 100 MeV within the Standard Model and account for all effects of permille size. We provide a complete error budget including uncertainties at nuclear, nucleon, hadronic, and quark levels separately as well as perturbative error. Our calculation starts from the four-fermion effective field theory to explicitly separate heavy-particle mediated corrections (which are absorbed by Wilson coefficients) from light-particle contributions. Electrons and muons running in loops introduce a non- trivial dependence on the momentum transfer due to their relatively light masses. These same loops, and those mediated by tau leptons, break the flavor universality because of mass-dependent electromagnetic radiative corrections. Nuclear physics uncertainties significantly cancel in flavor asymmetries resulting in subpercent relative errors. We find that for low neutrino energies, the cross section can be predicted with a relative precision that is competitive with neutrino-electron scattering. We highlight potentially useful applications of such a precise cross section prediction ranging from precision tests of the Standard Model, to searches for new physics and to the monitoring of nuclear reactors.
