Molten salt reactors as liquid-fuelled are flexible in terms of operation or design choices, but they very different design, and safety approach compared to solid-fuelled reactors. Such call for a new definition their operating procedures approach. Dedicated developments studies have been performed the frame European SAMOFAR project Horizon2020 parallel France involving CNRS, CORYS Framatome de...

Seismic analysis model is required to evaluate themechanical structural integrity of reactor internals when earthquakeis occurred. Finite element method is used to prepare a seismicanalysis model for reactor internals. The reactor internals arecomplex mechanical structures, so much analysis time is requiredto obtain the seismic responses with the detail finite element model....

To demonstrate the applicability and feasibility of AI technology in nuclear fields in China, a fuzzy controller to control the reactor power of China Advanced Research Reactor (CARR) is designed in this paper. The fuzzy controller uses Mamdani inference system based 2 inputs-power difference and power period, 1 outputvelocity of control rods. To evaluate the performance of the fuzzy controller...

Materials issues are a key concern for the existing nuclear reactor fleet in the United States as material degradation can lead to increased maintenance, increased downtime, and increased risk. Extending reactor life to 60 years and beyond will likely increase susceptibility and severity of both known and new forms of degradation. A multitude of concrete-based structures are typically part of a...

Poly(L-lactic acid) microspheres loaded with holmium-166 acetylacetonate (166Ho-PLLA-MS) are a novel microdevice for intra-arterial radio-embolization in patients with unresectable liver malignancies. The neutron activation in a nuclear reactor, in particular the gamma heating, damages the 166Ho-PLLA-MS. The degree of damage is dependent on the irradiation characteristics and irradiation time i...

In this work we present an accurate parameterization of the anti-neutrino flux produced by the isotopes 235U, 239Pu, and 241Pu in nuclear reactors. We determine the coefficients of this parameterization, as well as their covariance matrix, by performing a fit to spectra inferred from experimentally measured beta spectra. Subsequently we show that flux shape uncertainties play only a minor role ...

The neutron population in a nuclear reactor is subject to fluctuations in time and in space due to the competition of diffusion by scattering, births by fission events, and deaths by absorptions. As such, fission chains provide a prototype model for the study of spatial clustering phenomena. In order for the reactor to be operated in stationary conditions at the critical point, the population o...
