Whynter BWR-171DS Instruction Manual

Typical examples of each of these classes of BWR are: Mark I containments are equipped with lines connected to the wetwell that can be used to vent the containment if the pressure becomes too high.

In the sketch above there are 3 low pressure turbines, as is common for MWe plant. If a LOCA [loss of coolant accident] occurs, steam flows from the drywell through a set of vent lines and downcomers into the suppression pool, where the steam is condensed.

This electrical power is then distributed to a Generator Transformer, which steps up the voltage to eitherorvolts.

This template also does not apply to postage stamp designs published by the United States Postal Service since The BWR reactor typically allows bulk boiling of the water in the reactor. The report text describing the diagrams, on page 10 pdf 35 is: The water then passes to the Feedwater Pumps which in turn, pump the water to the reactor and start the cycle all over again.

The water eventually is heated enough to convert to steam.

The containment is divided into the drywell containing the reactor vessel and the wetwell torus containing the suppression pool. Steam can also be released Bwr 4 the reactor vessel through the safety relief valves and associated piping directly into the suppression pool.

In the event that the pressure in the wetwell exceeds the pressure in the drywell, vacuum breakers are provided that equalize the pressure.

The water in the suppression pool acts as an energy absorbing medium in the event of an accident. This only applies to original works of the Federal Government and not to the work of any individual U. The turbines are connected to each other and to the Generator by a long shaft not one piece.

The containments are constructed of either concrete or steel. The torus or suppression pool is used to remove heat released if an event occurs in which large quantities of steam are released from the reactor or the Reactor Recirculation System, used to circulate water through the reactor.

Steam separators in the upper part of the reactor remove water from the steam. The BWR is unique in that the Control Rods, used to shutdown the reactor and maintain an uniform power distribution across the reactor, are inserted from the bottom by a high pressure hydraulically operated system.

The operating temperature of the reactor is approximately F producing steam at a pressure of about pounds per square inch.Buy the World Tableware BWRBW White Dinnerware at KaTom. Low Prices Now on thousands of restaurant supplies.
