Abstract: A drilling system configured to install a tap assembly into a ship skin is disclosed. The drilling system comprises a remotely-operated underwater vehicle and a drilling assembly configured to be operated by the remotely-operated underwater vehicle. The drilling assembly comprises a frame comprising an attachment element configured to hold the drilling assembly to a surface of the ship skin. The drilling assembly further comprises a drill actuation system comprising a linear actuator attached to the frame and a rotary actuator, wherein an actuation of the linear actuator is configured to move the rotary actuator relative to the frame to install the tap assembly into the ship skin by driving the tap assembly with the rotary actuator and the linear actuator.

Abstract: A system for a monitoring lithography lasers at integrated circuit fabrication plants. Each laser at each fabrication plant has associated with it a terminal server. With respect to each fabrication plant a central control server unit is in communication with each of the lasers through a local area network. Information from the lasers is collected by the central control server unit and the information is used to provide summary information which is made available in a web site format to interested parties having access authorization.

Abstract: A nuclear fuel channel has four corners and four elongated sidewalls disposed between the corners so as to provide a polygonal transverse cross-section. Each of the channel sidewalls has a longitudinal centerline that coincides with a line of maximum stress that is imposed on the sidewall during in-reactor service. The sidewalls have one or more longitudinal off-center lines that are located between the longitudinal centerline and one of the corners abutting the elongated sidewall. The longitudinal off-center line coincides with a line of minimum stress imposed on an elongated sidewall during in-reactor service. A weld is formed along the length of the off-center line on at least two of the sidewalls. At least one of the off-center line welds is also a seam weld. The disclosed arrangement provides improved resistance to bulging of the channel sidewalls during in-reactor service.
