Abstract: A tooling assembly suitable for use in infiltrating a fibrous preform comprises a first perforated plate having an outer surface and an oppositely disposed inner surface defining a plate thickness therebetween, and a plurality of tapered holes extending through the thickness. Each hole of the plurality of tapered holes has a first diameter at the outer surface and a second diameter at the inner surface, and the first diameter is greater than the second diameter.

Abstract: A target irradiation system for irradiating a radioisotope target in a vessel penetration of a fission reactor, including a target delivery assembly including a body defining a central bore, a basket that is slidably receivable within the central bore of the body, and a winch that is connected to the basket by a cable, the target delivery assembly being affixed to the vessel penetration of the reactor, and a target passage that is in fluid communication with the target delivery assembly, wherein the basket is configured to receive the radioisotope target therein via the target passage and be lowered into the vessel penetration of the reactor when irradiating the radioisotope target, and the target delivery system forms a portion of the pressure boundary of the reactor when in fluid communication with the reactor.
