摘要： A method of fragmentation of elements of a nuclear reactor includes placement of elements inside a cask and subsequent cutting, the cask being perforated. Each element is lowered into the cask by a full internal height of the cask using a gripper having clamping jaws. The element is intercepted at an upper edge of the cask, lifted, and positioned using video surveillance and artificial lighting so that a hydraulic cutter is directly under the clamping jaws. The element is cut at a point corresponding to a level of the upper edge of the cask, separating from the element a fragment equal to the internal height of the cask. Then the upper part of the element remaining after cutting is lowered inside the cask by the full internal height of the cask and the cutting of the element into fragments is repeated until the element is fully cut to fragments.

摘要： One variation of a method for deploying a nuclear reactor system includes: constructing a tunnel at a particular location; and installing the nuclear reactor, loaded with a first core assembly, within the tunnel. The method further includes, during an operating period: in response to detecting a high-energy demand period: triggering operation of the nuclear reactor at a first capacity, directing a first portion of energy output to a charging station for charging electric vehicles, and directing a second portion, less than the first portion, of energy output to a gas sequestration subsystem; and, in response to detecting a low-energy demand period, triggering operation of the nuclear reactor at a second capacity less than the first capacity, directing a third portion of energy, less than the first portion, output to the charging station, and directing a fourth portion of energy, exceeding the second portion, output to the gas sequestration subsystem.

摘要： A method of compacting radioactive metal wastes comprising enclosing the radioactive metal waste in vacuo in a capsule, placing the capsule into a pressure container, and subjecting the capsule to an increased pressure at a high temperature to compact the waste. The compacting treatment is conducted in a state in which the atmosphere within the pressure container contains water molecules in an amount, in terms of the total weight W (g) thereof, the amount being preferably in the range of:1.3.times.10.sup.-6 .times.V.ltoreq.Wwherein V (cm.sup.3) is the volume of the compacting space in the pressure container. Alternatively, an oxide coating is formed on the outer surface of the capsule before the capsule is placed into the pressure container, or the formation of the oxide coating is followed by the compacting treatment conducted in the above-mentioned state.

摘要： A process for separating ceramic nuclear fuels out of metallic support mers or support member parts in which there adhere the nuclear fuels, especially subsequent to the burning down of the nuclear fuels in nuclear reactors. The ceramic nuclear fuels are washed off from the support member or carrier member part by means of a liquid jet which stands under a high pressure. The liquid jet is directed against the nuclear fuel, and the pressure of the liquid is set so high, that the nuclear fuel which adheres to the support member is completely removed. The liquid jet finds the transition from the ceramic nuclear fuel to the metallic support member material such that, even at a swelling of the fuel rod, and deformation of the support member part, there is achieved an efficient detaching of the nuclear fuel. The metallic support members or support member parts hereby remain intact and are segregated after the washing off of the nuclear fuel. Only the nuclear fuel fragments are introduced into the chemical solvent.
摘要翻译：一种将陶瓷核燃料从金属支撑构件或其中附着核燃料的支撑构件部分分离的过程，特别是在核反应堆中的核燃料焚烧之后。陶瓷核燃料通过在高压下站立的液体喷射器从支撑构件或载体构件部件中洗出。液体射流被引向核燃料，并且液体的压力被设置得如此高，使得附着到支撑构件的核燃料被完全去除。液体射流发现从陶瓷核燃料向金属支撑构件材料的转变，使得即使在燃料棒的膨胀以及支撑构件部分的变形的情况下也能实现核燃料的有效分离。金属支撑构件或支撑构件部件保持完整，并在核燃料的冲洗之后被分离。只有核燃料碎片被引入到化学溶剂中。
