Abrégé
A molten salt reactor system includes a fuel salt system configured to circulate a molten salt through a reactor vessel. The molten salt reactor system further includes an inert gas system fluidically coupled with the fuel salt system and configured to maintain a pressurized volume fluidically between the molten salt and a drain tank by circulating an inert gas along a first inert flow path. The molten salt reactor system further includes an equalization system configured to equalize pressure between all head spaces of the molten salt reactor system including the reactor vessel and the drain tank in response to a shutdown event. The inert gas system is configured to cease maintenance of the pressurized volume in response to the shutdown event.
In various embodiments, the stabilizing face ring joint flange and assemblies thereof can be adapted to include a ring joint gasket and resist leaks when a fluid flowing through a pipe at high temperatures and pressures. The stabilizing face ring joint flange assembly with the ring grooves in each flange can be situated in such a way that once full compression is achieved on the ring groove by the gasket, raised faces of the two flanges can meet to ensure that the rotation of the pump or any potential perpendicular loading do not provide a stress on the gasket that would cause the gasket to deform or cause a seal to be lost.

In one embodiment, an anhydrous hydrogen fluoride generator vessel (also referred to herein as the "AHF generator vessel") is provided. In several embodiments, an AHF generator vessel may include a container assembly, one or more shelves, and a center pipe assembly. The container assembly may include a lid assembly that may be removably coupled to the wall, and one or more feet. The center pipe assembly may include a base adapter, a center pipe, and a bottom adapter. In one embodiment, sodium bifluoride is loaded onto the one or more shelves which are positioned perpendicular to the center pipe and stacked upon one another. An external heat source may provide the heat to the vessel to thermally degrade the sodium bifluoride into HF and sodium fluoride (NaF). In various embodiments, the HF may be carried by a carrier gas out of the AHF generator vessel via the lid assembly.
A pipe connector for use in high temperature environments, such as those characteristics of molten salt reactors. The pipe connector can be used in any industry that uses pipe connectors, and in particular, can be used in a molten salt system including a reactor requiring a connection rated for greater than 700 °C and up to 15,000 psi. The pipe connector 100 may comprise a pin 110, a seal ring 140, a retainer ring 150, a box 160, a locking nut 180, and a retaining nut 190.

IDENTIFYING AND QUANTIFYING COMPONENTS IN A HIGH-MELTING-POINT LIQUID
Apparatus, systems, and methods for identifying and quantifying chemical components in a high-melting-point liquid. One such method includes: receiving, into a nebulizer assembly, a high-melting-point liquid from a molten liquid conduit; aerosolizing, using the nebulizer assembly, at least a portion of the received high-melting-point liquid; delivering, into one or more instruments, the aerosolized high-melting-point liquid from the nebulizer; and chemically analyzing, using the one or more instruments, the aerosolized high-melting-point liquid.

APPARATUS, SYSTEMS, AND METHODS FOR NON-INVASIVE MEASUREMENT OF FLOW IN A HIGH TEMPERATURE PIPE
A method, apparatus, and system according to which first and second transducers are connected to first and second waveguides, respectively, the first and second waveguides are connected to a pipe, and ultrasonic wave signals are exchanged between the first and second transducers, said ultrasonic wave signals passing through the first and second waveguides, the pipe, and a fluid in the pipe. A temperature of the fluid flowing in the pipe may exceed about 600 C. The first and second waveguides insulate the first and second transducers from the pipe and propagate the ultrasonic wave signals between the pipe and the first and second transducers, respectively, so that the ability of the first and second transducers to exchange the ultrasonic wave signals is not adversely affected by the temperature of the fluid in the pipe. The first and second waveguides may be made of a calcium silicate technical ceramic.
