International Classification:

G21C 736

US Classification:

376217, 376230, 376259

Abstract:

A transponder card for a nuclear reactor control rod drive control system is provided. The control system includes a control processor and a plurality of electrical devices operationally coupled to the control processor. The transponder card is configured to receive commands from the control processor, energize an appropriate electrical device when commanded, detect a failure in control circuitry of the transponder card, send a failure alarm, and remove power from an electrical device during a control circuitry failure event when there is no command to energize the electrical device.

Abstract:

A branch amplifier card for a nuclear reactor control rod drive control system is provided. The control system includes a control processor, a plurality of transponder cards arranged in clusters with each cluster under the control of a branch amplifier card. The branch amplifier card is configured to receive commands from the control processor, send the converted commands to transponder cards under the control of the branch amplifier card and to a downstream branch amplifier card, receive an acknowledge word from transponder cards under the control of the branch amplifier card, add AC voltage threshold level information about the transponder cards under the control of the branch amplifier card to the acknowledge word, permit transponder trouble information attached to the acknowledge word to remain in the acknowledge word, and resend the acknowledge word including the transponder trouble information to an upstream branch amplifier card.

International Classification:

G06F017/60

US Classification:

705 28, 707 3

Abstract:

A business process utilizes computer software and electronic customer/supplier connections to supply information, receive requests for quotation, supply quotations, receive purchase orders, and perform commercial and technical functions associated with delivery of such purchase orders or quotations with respect to environment and use specific products. Such products require customer or plant application unique technical evaluation and/or commercial processing to ensure applicability to a specific customer application. The system provides a vehicle to search for parts requiring such technical review encompassing anticipated product use.

International Classification:

G06F 1730

US Classification:

707 1

Abstract:

A system for managing multiple projects of a similar type has a global project management database for storing data for all participating projects which is dynamically updated with best current data representing best current practices across all participating projects in the system. Localized computer terminals are operated at each local site with a common project management program and data imported from the global project management database. Periodically, the local terminals export data to the global project management database which are evaluated to determine any new best current practices across all participating projects and to update the global project management database with the new best current practices. Upon periodically importing data from the global project management database, each localized computer terminal is updated with the new best current practices across all participating projects.
