    摘要: Изобретение относится к атомной технике, в частности, к ядерным реакторам с водой под давлением. Ядерный реактор с водой под давлением содержит тепловыделяющие сборки, расположенные в ячейках активной зоны, поглощающие стержни системы регулирования и защиты, стержни с вторичными источниками нейтронов, размещенные вблизи от ионизационных камер в тех ячейках активной зоны реактора, в которых отсутствуют поглощающие стрежни, и закрепленные на траверсе. Каждый стержень с вторичным источником нейтронов герметизирован наконечником и подвеской и выполнен в виде полой трубки, заполненной гелием под давлением, в которой размещена герметичная капсула, заполненная гелием по давлением. Капсула содержит таблетки из смеси изотопов бериллия и сурьмы, зафиксированные от осевого перемещения фиксатора, расположенным в свободном объеме внутри капсулы. Центрирование капсулы в стержне осуществляется с помощью дистанционирующего элемента. Изобретение позволяет повысить безопасность и ускорить повторный пуск ядерного реактора с водой под давлением.

    摘要: A method of storing a chimney assembly of a reactor pressure vessel during a nuclear reactor outage may include detaching a chimney barrel with upper chimney partitions therein from a top guide assembly of the reactor pressure vessel. A height of the upper chimney partitions is less than a height of the chimney barrel so as to leave a plenum region in a top section of the chimney barrel. The top guide assembly includes lower chimney partitions therein. The lower chimney partitions are removed from the top guide assembly and inserted into the plenum region of the chimney barrel so as to be on the upper chimney partitions. As a result, the chimney assembly can be stored in a relatively compact form during a reactor outage. The chimney assembly may be a combination of at least the chimney barrel, the upper chimney partitions, and the lower chimney partitions.

    摘要: A nuclear reactor core comprises a calandria having a shell and a tube sheet defining an aperture, a calandria tube coupled to the tube sheet and extending into the shell, a lattice tube coupled to the tube sheet and extending away from the shell, an end fitting body positioned at least partially in the lattice tube, a pressure tube positioned at least partially in the calandria tube and have an end secured to the end fitting body; and an end fitting liner positioned at least partially in the end fitting body coaxial with the pressure tube. An end of the end fitting liner adjacent the pressure tube includes a first inner surface having a roller clearance counter bore. The counter bore provides clearance to avoid contact between a rolling tool and the end fitting assembly.

    摘要: The invention relates to the pressure vessel of a reactor (2) comprising a flow space (8) arranged between the reactor core (6) and a separation device (10) for separating water from water steam, the surface area of the flow section of said space expands upstream the separation device (10), thereby making it possible to pre-separate a water-water steam mixture (G) coming from the reactor core (6). Due to said pre-separation, only the central area is provided with a cyclone device (24), and only drying equipment (26) is disposed near said cyclone device (24). Said invention makes it possible to reduce the height of the pressure vessel of a reactor (2).

    摘要: The transmutation of radioactive material using a hybrid transmutation reactor is disclosed wherein a kinetic proton source is used to collisionally induce the transmutation of radioactive material with the generation of thermal neutrons as a byproduct. Additionally, a system and method for the production of Tritium utilizing the thermal neutrons generated in the transmutation process is further described. The present invention offers advantages and improvements over existing nuclear reactor technologies in that nuclear waste may be rendered inert, or otherwise at least partially deactivated and/or made less dangerous, with the substantially simultaneous production of energy and/or Tritium as a byproduct of the transmutation process.

    摘要: A method for reparing cracked jet pump riser assemblies (56) in a boiling water reactor utilizes a spacer clamp (80) and a seal collar (148). The spacer clamp is secured to the jet pump riser assembly to limit horizontal displacement between a shroud (18) and the jet pump riser assembly. A method for reparing a circumferential weld (72) connecting an elbow (70) of the jet pump riser assembly with a thermal sleeve (74) involves positioning the weld within the seal collar to limit leakage from the weld. The seal collar includes a pair of hinged jaw members movable between an open position and a close position for receiving a pipe therebetwen. The seal collar includes a pair of seals disposed along inner surfaces (176A and 177A) of the jaw members to circumferential contact with the pipe on opposite sides of the weld to limit leakage.
