The reactor involved in the Chernobyl nuclear accident was a 1, 000-MWe(3, 200-MWt) RBMK, a boiling-water pressure-tube, graphite moderated power reactor that was developed and operated in the former Soviet Union. Because of the pressure-tube design using water as coolant within channels in the graphite moderator, RBMK reactors have a significant positive void coefficient of reactivity in which a reduction in the coolant density results in an increase in the system reactivity due to a reduction in neutron absorption by the coolant. 1, record 2, English, - positive%20void%20coefficient%20of%20reactivity

In a nuclear plant of Westinghouse design the reactor coolant system components may be forged or cast stainless steel and varies from plant to plant. The reactor coolant pump casings are always cast. Both forged and cast product forms exhibit exceptionally high toughness in the as-build condition; however, the cast material is susceptible to thermal aging. Thermal aging causes significant reduction in fracture toughness, while the tensile strength and yield stress of the materials most often increase. 1, record 3, English, - thermal%20aging

La dénomination de «vieillissement thermique» recouvre toute une série de mécanismes basés sur la diffusion des éléments chimiques et permettant aux «systèmes» métallurgiques de revenir à un état d'équilibre thermodynamique plus stable, sous l'effet de la température de fonctionnement (entre 290 et 350 °C dans le cœur des REP [réacteur à eau sous pression]). Ce retour à l'équilibre se traduit par une évolution microstructurale et par une évolution des propriétés des matériaux. Les principaux mécanismes de vieillissement thermique susceptibles d'apparaître sont la précipitation, la mise en ordre, le vieillissement dynamique et la ségrégation de certaines espèces chimiques. Tous ces mécanismes conduisent plus ou moins à une fragilisation du matériau (avec ou sans durcissement). 3, record 3, French, - vieillissement%20thermique

In a nuclear electric propulsion system, heat from a nuclear reactor is converted to electrical energy either by direct thermoelectric or thermionic conversion. NEP provides higher power, thrust, and specific impulse than a SEP [solar electric propulsion] system, although the thrust still pales to insignificance compared to our chemical rockets. For a comparison specific impulse of chemical rockets is about 400secs, Deep Space 1 uses SEP and produces around 3300secs, NEP on the other hand could produce specific impulse as high as 13, 000secs. 1, record 9, English, - nuclear%20electric%20propulsion

CANDU plants can be operated in two basic modes :reactor-following-turbine(RFT) and turbine-following-reactor(TFR). Steam generator pressure control plays a pivotal role in these schemes. In TFR mode the reactor power is held constant at a level set by the operator and the turbine governor control valves are used to regulate steam pressure. This mode is suitable for unit operation within a large system network where it is used to supply the base loads while other units are used to supply peak loads. Since reactor conditions remain constant, this mode also constitutes a safer state of operation from the nuclear plant perspective. The control system reverts to this mode of operation during plant upsets. In RFT mode, the turbine load is set by the operator and the reactor is used to regulate steam pressure. In both TFR and RFT modes, the turbine is also used to regulate speed and assist the system in meeting short-term changes in electrical load demand. In RFT mode, the governor control valves also attempt to maintain a constant generator output. 1, record 15, English, - turbine%2Dfollowing%2Dreactor

The power plant operator must promptly and correctly diagnose the initiating event. He accomplishes this mentally, based on training and prior experience. As a result of this instant evaluation, he then selects the event-oriented procedure that best fits his diagnosis. For example, if his evaluation indicates that a small steam line break has occurred in the reactor building when, in actuality, a small loss of coolant has occurred in the building, he would implement the wrong event-oriented procedure.

Record number: 29, Textual support number: 1 CONT
Inside the building housing a reactor which is undergoing a major nuclear accident, internal steam pressure can be greatly reduced by using a dousing system to condense the steam. All CANDU reactors are provided with such a dousing system. It is much more difficult to reduce the pressure from non-condensable gases which are formed in great quantities during meltdown. 6, record 29, English, - dousing%20system
Record number: 29, Textual support number: 2 CONT
The Containment System forms a continuous, pressure-confining envelope around the reactor core and primary heat-transport system. In the CANDU 6 design it consists of a pre-stressed, post-tensioned concrete structure, an automatically-initiated dousing system, building coolers, and a filtered air discharge system. In Ontario Hydro’s multi-reactor designs, containment includes a vacuum building connected to all reactor vaults in the plant, with its own dousing system for reducing internal pressure. 7, record 29, English, - dousing%20system
