Abstract: A process for reducing residual tensile stresses in high nickel-chromium alloy nozzle safe-end welds of pressurized water reactor nuclear pressure vessels such as are found at the reactor vessel inlet and outlet nozzles and the pressurizes surge, spray, safety and relief nozzles. The process involves the application of radial compression on the outside surface of the nozzle's safe-end and/or connecting coolant piping, to reduce the outside diameter at the mid-point of the piping element to which the load is applied to between about 0.2% and about 3%. The radially compressive load applied by this process is imparted using a mechanical device that can be employed at the vessel manufacturer's facility or at a nuclear power plant after welding of the nozzle safe-end to the coolant piping or before either after plant commissioning of operation.

Abstract: An apparatus for capturing and storing a co-marketer identification symbol representing an identity of an entity that has referred a user on a user station to a computer service, wherein the user station is coupled to the computer service by a communications path. A database is provided for storing a plurality of user records. Each of the user records includes a user identification field for storing information uniquely associating each of the user records with a user, and a co-marketer identification field for storing identity information representing the identity of an entity that directed the user to the computer service. An enrollment means is coupled to the communications path and the database, and is provided for enrolling a user on the computer service. The enrollment means includes means for determining a co-marketer that directed the user to the computer service, and means for assigning a unique user identification number to the user.
