摘要： A fuel pin for a liquid metal nuclear reactor is provided. The fuel pin includes a generally cylindrical cladding member with metallic fuel material disposed therein. At least a portion of the fuel material extends radially outwardly to the inner diameter of the cladding member to promote efficient transfer of heat to the reactor coolant system. The fuel material defines at least one void space therein to facilitate swelling of the fuel material during fission.

摘要： The invention relates to a nuclear reactor spacer grid member for use in a liquid cooled nuclear reactor and to a ductless core component employing a plurality of these spacer grid members. The spacer grid member is of the egg-shell type and is constructed so that the walls of the cell members of the grid member are formed of a single thickness of metal to avoid tolerance problems. Within each cell member is a hydraulic spring which laterally constrains the nuclear material bearing rod which passes through each cell member against a hardstop in response to coolant flow through the cell member. This hydraulic spring is also suitable for use in a water cooled nuclear reactor. A core component constructed of, among other components, a plurality of these spacer grid members, avoids the use of a full length duct by providing spacer sleeves about the sodium tubes passing through the spacer grid members at locations between the grid members, thereby maintaining a predetermined space between adjacent grid members.
摘要翻译：本发明涉及一种用于液冷核反应堆的核反应堆间隔网格构件和采用多个间隔网格构件的无管芯组件。间隔网格构件为蛋壳型，并且构造成使得栅格构件的单元构件的壁由单一金属厚度形成以避免公差问题。在每个电池构件内是液压弹簧，其液压弹簧横向地约束穿过每个电池构件的核材料轴承杆，以响应于通过电池构件的冷却剂流而抵抗硬停止。该液压弹簧也适用于水冷核反应堆。除了其他部件之外，构成多个这些间隔网格构件的芯部件避免了通过在电栅部件之间的位置处通过间隔栅格部件的钠管提供间隔套筒来避免使用全长管道，从而保持相邻网格构件之间的预定空间。

摘要： A locking connection for releasably attaching a handling socket to the duct tube of a fuel assembly for a nuclear reactor. The connection comprises a load pad housing mechanically attached to the duct tube and a handling socket threadably secured within the housing. A retaining ring is interposed between the housing and the handling socket and is formed with a projection and depression engageable within a cavity and groove of the housing and handling socket, respectively, to form a detachable interlocked connection assembly.
