Cubic-meter-sized antineutrino detectors can be used to non intrusively, robustly, and automatically monitor and safeguard a wide variety of nuclear reactor types, including power reactors, research reactors, and plutonium production reactors. Since the antineutrino spectra and relative yields of fissioning isotopes depend on the isotopic composition of the core, changes in composition can be o...

In the last decade nuclear reactors have proven to be a source of electrical energy economically competitive with conventional means of power production. With the resulting increase in orders for nuclear power stations there has been a corresponding increase in public awareness of the safety and environmental aspects of these facilities. This public awareness has been evidenced by the number of...

Increasing complexity in reactor designs suggests a need to reexamine of methods applied in spent-fuel characterization. The ability to accurately predict the nuclide composition of depleted reactor fuel is important in a wide variety of applications. These applications include, but are not limited to, the design, licensing, and operation of commercial/research reactors and spent-fuel transport...

We discuss the feasibility of using the detection of electron antineutrinos produced in fission to monitor the time dependence of the Plutonium content of nuclear power reactors and large (> 1 MWatt) research reactors. If practical such a scheme would allow worldwide, automated monitoring of reactors and, thereby, the detection of proliferation attempts. Although this idea shows some promise, w...
