    摘要： Various embodiments of the teachings herein include a solid insulation material based on a resin containing epoxy groups for production of an anhydride-free insulation system by means of VPI. The material comprises: an anhydride-free curing catalyst; and an additive for improving distribution of the anhydride-free curing catalyst, wherein the additive comprises a phenyl carboxylate. The additive is present in an amount based on the epoxy groups in the resin containing epoxy groups which is present in the impregnating agent of at least 0.1% in stoichiometric terms.

    摘要： Provided is an insulating sheet capable of effectively enhancing thermal conduction and adhesiveness and effectively suppressing generation of voids. The insulating sheet according to the present invention contains a thermosetting component and boron nitride, the insulating sheet has a first surface on one side in a thickness direction and a second surface on the other side in the thickness direction, and a first average major diameter of the boron nitride in a region having a thickness of 10% of a thickness of the sheet, from the first surface toward the second surface is smaller than a second average major diameter of the boron nitride in a region having a thickness of 90% of a thickness of the sheet, from the second surface toward the first surface.

    摘要： A method of operating a nuclear reactor includes operating a valve actuator to open and close a valve in fluid communication with a nuclear reactor fluid control system. The valve actuator includes a motor having windings of magnet wire. The magnet wire includes a layer of insulating material disposed over a conductor. The layer of insulating material comprises polyetheretherketone (PEEK) and has a thickness between about 0.025 mm and about 0.381 mm. A method of replacing a valve actuator motor with such a motor having windings formed of PEEK-insulated magnet wire is also disclosed. A method of coupling a valve actuator with such a motor having windings formed of PEEK-insulated magnet wire to a valve is also disclosed.
