Accordingly, the fuel efficiency mode for artificially turning off the PWM control of the LDC is added, so that when the fuel efficiency mode is performed, power of an auxiliary battery is temporarily supplied to an electric field load, thereby reducing power consumption of a main battery and improving fuel efficiency. Further, when the auxiliary battery is separated, power of the main battery is temporarily supplied to the electric field load by performing the PWM control of the LDC, to prevent a phenomenon that power is not supplied to the electric field load when the auxiliary battery is separated.

Abstract: An oil pump includes a pump housing comprising an oil input port formed at one side of the pump housing. An oil output port is formed at another side of the pump housing. An oil flow unit is provided at a center of the pump housing, and the oil flow unit compresses and discharges oil input from the oil input port toward the oil output port. A bypass passage circulates the oil from the oil output port to the oil input port. A pressure control chamber allows the oil to flow through the oil output port and the bypass passage.

A bypass hole is formed at one side of the pressure control chamber and allows the oil passing through the oil output port to flow to the bypass passage when the plunger moves due to the oil pressure. The amount of oil flow increases depending on a movement distance of the plunger.

Abstract: A zirconium alloy for use in nuclear fuel assemblies is provided, which provides increased resistance against oxidation and corrosion and also improved bonding with parent material, because pure metallic material such as silicon (Si) or chromium (Cr) is evenly coated on the surface of the parent material by plasma spraying. Because the plasma spray coating used to coat the pure metallic material on the zirconium alloy does not require vacuum equipment and also is not limited due to the shape of the coated product, this is particularly useful when evenly treating the surface of the component such as 4 m-long tube or spacer grip arrangement which is very complicated in shape. Furthermore, because the coated zirconium alloy confers excellent resistance to oxidation and corrosion under emergency such as accident as well as normal service condition, both the economic and safety aspects of nuclear fuel are improved.
