Nuclear new build procurement considerations
It may seem counterintuitive, but the best time to enhance the ability to support operations and maintenance for a new plant is before construction starts. This is one of many lessons learned by the currently operating nuclear fleet. As construction and startup of many nuclear facilities was completed, it quickly became evident that the ability to efficiently support operations and maintenance was limited. Most of the information necessary to establish and manage procurement of spare and replacement items, maintenance, and configuration of the facilities was unavailable and had to be gathered on a case-by-case, “on-demand” basis. Absence of necessary information and the associated challenges resulted in the need for staff augmentation and multiyear-long projects to develop equipment bills of material and maintenance programs and to perform technical evaluations for the huge quantities of spare and replacement items being requested.

This paper presents the generation of modes of angular momentum of the orbital type using a proposed array antenna fed with Rotman lens of multiple layers of compact size. The gain of orbital angular momentum is enhanced by the proposed microstrip antenna, which is a circular array antenna with nine elements fed with Rotman lens utilizing the patch element of high gain. Antenna gain can be enhanced in an effective manner; the patch element is attached with two slots loaded in a stacked patch. The circular array when employing the feeding network with Rotman lens causes excitation of different input ports, which produces carrying beams of orbital angular momentum with mode numbers m = 0, m = ±1, m = ±2, m = ±3, and m = ±4. A phase shift of 160 deg is achieved on the output ports in the adjacent position for meeting the requirement of the phase of orbital angular momentum modes of m = ±4. The detection angle of the ports of the beam and array is adjusted by modifying the Rotman lens for achieving the uniform distribution of amplitude on the output ports of the antenna. Therefore, effective improvement is observed in the radiation pattern of the orbital angular momentum beams, which obtains equal amplitude in all the output ports. The fabrication of a prototype antenna of C band is done, and measurements are performed. Simulated results match the measured results, indicating that generation of orbital angular momentum is done by the antenna proposed in this paper, which can be used in communication systems based on orbital angular momentum.
