Abstract: A device for in-situ corrosion monitoring in a molten salt reactor system includes a mounting structure and a plurality of probes. Each probe of the plurality of probes may have a main portion and a thinned region that together define a sealed chamber with the mounting structure. Each thinned region of the plurality of probes may be configured to corrosively fail, when exposed to a corrosive environment, both: (i) before any main portion of the plurality of probes, and (ii) temporarily in series with the other thinned portions of the plurality of probes. The device may further include a plurality of sensing features corresponding to the plurality of probes, each sensing feature disposed in a respective sealed chamber of the plurality of probes. Each sensing feature may be configured to detect a breach of the respective sealed chamber caused by the corrosive failure of the thinned region.

Abstract: 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.

Abstract: The disclosure includes a heat-staking device comprising a base, an upright arm coupled to the base, and a head vertically movable along the upright arm. In some embodiments, the head includes a main head unit, a quill coupled to the main head unit, an insulating tip holder coupled to the quill and configured to removably retain a thermal-installation tip, and a handle configured to cause vertical motion of the insulating tip holder. The quill may also include a soldering iron configured to heat the thermal-installation tip. In some embodiments, the heat-staking device is configured to swap out thermal-installation tips while the thermal-installation tips are still hot.

Abstract: This disclosure is related to devices and related methods for isolating a treatment region in a human body from fluid pressure. In various embodiments, an implantable device for isolating a treatment region in a human body from fluid pressure comprises a first elongated segment, and a second elongated segment, and one or more branch segments in fluid communication with one of the first elongated segment and the second elongated segment. The elongated segments have a combined cross section that is substantially conformable to an intraluminal cross section of a body lumen into which they are implanted. A method of installing an implantable medical device into the body of a patient comprises deploying a first elongated segment, deploying a second elongated segment, and deploying one or more branch segments in a target region of a vasculature.

Abstract: Various aspects of the present disclosure are directed toward a steerable endovascular graft delivery device including an anti-cannulation member. The delivery device generally includes a guide wire extension element, a steering wire, and a membrane. The steering wire is operable to deflect a distal end of the guide wire extension element, and the membrane is operable to prevent cannulation of the gap that is formed between the guide wire extension element and the steering wire when the distal end of the guide wire extension element is deflected.
