Nuclear power plant with the valve working conditions and the requirements of the valve
(1) the main types of nuclear power plant in Figure 3-292 (valve optional manual) expressed in a nuclear power plant into electric energy from nuclear power and the process schematic.
A coolant loop will be issued within the reactor axis rod heat incoming steam generator, and where the heat of the working media to pass the secondary circuit. Steam turbine generator to promote the production of steam to drive the generator rotor rotation and to generate electricity. The first loop is a loop reactor, and the second loop is the steam generator circuit.
(2) Glossary of water - water reactors - there are two kinds of pressurized water and boiling water reactors. In the pressurized water reactor, the water used for both the slow agent, useful to do the cooling agent, in any normal operating conditions, as well as from one condition to another condition over when the maximum temperature of water with low total in the coolant loop may appear in a minimum pressure corresponding saturation temperature. In the boiling water reactor, then the use of the work under the pressure of the provisions of the corresponding saturation temperature of the soda mixture to make slow-agent and coolant.
Water-cooled graphite (uranium - graphite) reactors: In this reactor, the graphite is used to slow agent, water, steam - water mixture or superheated steam used as a cooling agent, which are arranged along the graphite in the core of parallel block Process flow of the pipeline, which processes the import pipeline in conjunction with the coolant tube and pipe exports in conjunction with each other connected.
Steam generator: it is from the shell and the shell composed of piping within the equipment used to produce steam, which rely on a coolant loop to heat and vaporize the water within the secondary circuit which generate steam.
Regulators: used to maintain a loop pressurized water reactor pressures of working within the same equipment, by using steam or gas cushion pad to compensate for a water-filled circuit due to temperature changes caused by changes in water volume.
A circuit: the main loop pressurized water reactor loop, which is from the reactor, steam generator (heat exchanger), the main circulating pumps, valves and piping to connect these devices, as well as systems composed of regulators. Graphite - water-cooled reactors, a return to the routing process within the reactor pipe, joint control, separation drum, driven by the cooling agent in the loop to achieve a mandatory combined-cycle pumps, valves and connecting piping and other circuit devices formed.
A loop system: through the loop including main and auxiliary systems, such as the cooling agent on the charge, discharge and purification systems, other independent processes within the loop-loop heating and cooling systems, reflective of waste emissions from a loop and storage systems.
2 circuit: it is separated from the steam generator or steam turbine before the main steam drum into the steam pipeline valve, condensation water pipeline, water supply pipeline, piping and steam vacuum extraction pipes and all appliances.
Experimental Reactor 2 circuit: it is by the acceptance of a loop heat pipe related equipment, and composed.
(3) nuclear power plant the main characteristics of the valve size parameter and performance parameters depend largely on the capacity of nuclear power plant process parameters and mechanical parameters, and these parameters are primarily determined by its own power nuclear power plant the size and type.
