摘要： The deep-pool nuclear reactor for district heating is a novel type of nuclear reactor technology for district heating purposes. This invention provides a design for a deep-pool reactor with fairly high outlet water temperature which can meet the requirements of medium and small size district heat grids while retaining the simplicity, high inherent safety, and lower economic-scale of pool-type reactors. The depth of the reactor pool (6) is increased to keep the reactor core (14) under static pressure of pool water and the hot water enters the heat exchanger (5) from the bottom (17) to keep high saturation temperature of the reactor outlet (3) cooling water. The advantages of this design include; simplicity in structure, better safety features, lower capital investment, easy operation and maintenance, the possibility of comprehensive utilization, and hence higher economic benefit.

摘要： Air-hardenable steels of duplex bainite/martensite microstructure consisting essentially of 0.10 to 0.7% C, 0.1 to 2% Si, 2.1 to 3.5% Mn, 0.0005 to 0.005% B, up to 3.5% Cr and preferably containing Cr in amount of at least 0.1%, balance Fe except for incidental impurities. Optional elements are up to 1.5% W, 1.0% Mo, 0.15% V, 0.2% S, 0.1% Ca, 0.1% Pb, 0.1% Ti and 0.2% total rare earths. At least 1.0% Cr is especially preferred and if below such amount, total Mn and Si is at least 3% and in such case, if C is under 0.47%, at least 0.6% Si is present. The steels are hardenable to R c 20 to R c 58 and have a hardenable diameter in the range between 35 mm and 80 to 100 mm by air-cooling only, together with good strength, toughness and fatigue- and wear-resistance.

摘要： The hydraulic step cylinder of orifice type is a new type of driving device of the control rod; it is fitted for water power reactor. In the cylinder the water - reactor coolant - is used as working medium, the drag between piston (1, 2) and cylinder (3) is changed with a stagger of the orifices (11, 21, 31) which are on them, the piston (1, 2) can be moved step by step by controlling of the flow. It has no sealing problems of too high pressure which are faced in usual driving devices of control rod on power reactor, so it can be put into the reactor vessel. Its properties are better than the "hydraulic control rod" of KWU, F.R.G. (the groove type). It is a simpler and cheaper device of the control rod of a power reactor. It will play an important part in reducing the reactor scale and in simplifying the reactor structure.
