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.
