“…Researchers from the United States proposed a hightemperature reactor, a fluoride-salt-cooled reactor that used coated particle fuel and was cooled by the salt, and conceptually and experimentally investigated the core design [8,9]. A liquid-salt microreactor (MARS) was designed in Russia for space exploration [10]. Feasibility and safety assessments of liquid-fuel fast-reactor systems (EVOL and SAMOFAR) have been performed in the Euratom framework project, and the fast-spectrum MSR concept (MSFR) was developed to investigate the feasibility of applying the MSR for fuel breeding and nuclear waste transmutation [11][12][13][14].…”

A molten-salt reactor (MSR), in which the nuclear waste can be separated and taken away from the liquid fuel through online chemical treatment, has remarkable advantages in safety and economics. To ensure the safe operation of an MSR plant, it is necessary to carry out a controller design and stability analysis of the whole system. In this work, a nonlinear distributed-parameter model of an MSR plant with a graphite-moderated liquid core was established and verified by the reference model. By applying a joint feedforward and feedback control strategy, the power controller and steam temperature controller were designed to adjust the plant load. The Nyquist criterion was used to assess the stability of the control system. The system responses to four different perturbations at the nominal power level were simulated, and the results show that the designed controllers have good reliability. In addition, the control performance was tested in two load change cases: a step load reduction and a linear load change. The dynamic response characteristics of the system parameters show that the developed control system based on the nonlinear distributed-parameter model is capable of fast and accurate regulation.

“…Nuclear power is considered to be the best choice to satisfy the demand of future energy in environmental protection, fuel economy, saving cost, etc. The molten salt reactor (MSR) has been selected as one of the most promising next-generation nuclear reactors, due to its incomparable advantages for online refueling and removing fission products, good heat transfer characteristics, high security, along with hydrogen production capability [1][2][3]. The eutectic molten fluoride salt is widely used as fuel carrier and coolant medium in MSR to transfer heat from nuclear reactors to plants.…”

Corrosion test of a Ni-16Mo-7Cr alloy with a decarburized layer was conducted in FLiNaK salt at 700°C. A detailed microstructure study was performed to investigate the corrosion behavior and mechanisms. The results show that the Ferich layers were formed on the corroded alloys with and without decarburization. The surface decarburization had little influence on the corrosion resistance of the alloy, whereas it caused more M 2 C carbide formation beneath the corrosion layer. That is attributed to the higher concentration of C gradient near the alloy surface, which was resulted from the increase in C content liberated from graphite crucible wall during the corrosion process.

The effect of long-term thermal exposure on the carbide evolution in a Ni-16Mo-7Cr base superalloy was investigated. The results show that M12C carbides are mainly precipitated on the grain boundaries during thermal exposure, and the primary massive M6C carbides can be completely transformed to M12C carbides in situ at temperatures above 750 °C for long-term thermal exposure. The transformation from M6C carbides to M12C carbides is attributed to the release of C atoms from M6C, which results in the morphology changes of massive carbides, and stabilization of the sizes of M12C carbides precipitated on the grain boundaries.
