Abstract: A communication system transmits data between a plurality of locations. The communication system is suitable for use by a utility provider to monitor a plurality of metering devices from a remote location. The communication system in accordance with use by a utility provider to monitor metering devices comprises a control for at least receiving data, a plurality of metering devices arranged in a defined number of metering groups for transmitting data associated with an amount of usage of a utility, and a defined number of concentrators, each operably connected to the control and one metering group for transmission of data between the control and plurality of metering devices.

Abstract: The present invention relates to method of fueling and operating a nuclear reactor core. Fueling the nuclear reactor core for a power operation cycle includes the steps of designating a central core region, a buckled core region and a peripheral core region, placing at least two fuel assemblies of relatively high reactivity in the fuel cells in the central core region and placing fuel assemblies of relatively low reactivity in the cells in the peripheral core region.

Abstract: A control system for avoiding coupled neutronic-thermal hydraulic instabilities during maneuvering of a boiling water nuclear reactor that determines the average elevation in the reactor core of the coolant boiling boundary, and avoids instabilities by maintaining the core average coolant boiling boundary elevation above a target value, which is dependent on reactor design specifics but may be about four feet, in core power-flow operating regions which are subject to instabilities. The system may be implemented without physical modification of existing reactors or reactor instrumentation and control systems through use of the reactor core monitoring computer, which typically has available all core parameters necessary for the computations required in the invention.
