Reactor Power

Some articles on power, reactor, reactor power, reactors:

Chernobyl - Accident - Conditions Prior To The Accident
... As planned, a gradual reduction in the output of the power unit was begun at 0106 on 25 April, and the power level had reached 50% of its nominal 3200 MW thermal level by the beginning of the day shift ... At this point, another regional power station unexpectedly went offline, and the Kiev electrical grid controller requested that the further reduction of Chernobyl's output be postponed ... At 2304, the Kiev grid controller allowed the reactor shut-down to resume ...
Chernobyl - Causes - Operating Instructions and Design Deficiencies Found
... of the USSR State Committee for the Supervision of Safety in Industry and Nuclear Power has reassessed the causes and circumstances of the Chernobyl accident and came to new insights and conclusions ... These included operating the reactor at a low power level – less than 700 MW – a level documented in the run-down test program, and operating ... regulations did not prohibit operating the reactor at this low power level ...
Chernobyl - Accident - Experiment and Explosion
... During this period, the power for the four MCPs was supplied by the turbine generator as it coasted down ... Because of the positive void coefficient of the RBMK reactor at low reactor power levels, it was now primed to embark on a positive feedback loop, in which the ... yet more water to flash into steam, giving yet a further power increase ...
Vogtle Electric Generating Plant - Power Uprate
... In 2008, both reactors were increased in power by 1.7% by an "Appendix K" uprate, also called a Measurement Uncertainty Recapture uprate ... "Measurement uncertainty recapture power uprates are less than 2 percent and are achieved by implementing enhanced techniques for calculating reactor power ... feedwater flow, which is used to calculate reactor power ...
Void Coefficient - Reactor Designs
... Boiling water reactors generally have negative void coefficients, and in normal operation the negative void coefficient allows reactor power to be adjusted by changing ... void coefficient can cause an unplanned reactor power increase in events (such as sudden closure of a steamline valve) where the reactor pressure is suddenly increased ... the negative void coefficient can result in power oscillations in the event of a sudden reduction in core flow, such as might be caused by a recirculation pump failure ...

Famous quotes containing the word power:

    You only have power over people so long as you don’t take everything away from them. But when you’ve robbed a man of everything he’s no longer in your power—he’s free again.
    Alexander Solzhenitsyn (b. 1918)
