摘要： An advanced control room complex for a nuclear power plant, including a discrete indicator and alarm system (72) which is nuclear qualified for rapid response to changes in plant parameters and a component control system (64) which together provide a discrete monitoring and control capability at a panel (14-22, 26, 28) in the control room (10). A separate data processing system (70), which need not be nuclear qualified, provides integrated and overview information to the control room and to each panel, through CRTs (84) and a large, overhead integrated process status overview board (24). The discrete indicator and alarm system (72) and the data processing system (70) receive inputs from common plant sensors and validate the sensor outputs to arrive at a representative value of the parameter for use by the operator during both normal and accident conditions, thereby avoiding the need for him to assimilate data from each sensor individually. The integrated process status board (24) is at the apex of an information hierarchy that extends through four levels and provides access at each panel to the full display hierarchy. The control room panels are preferably of a modular construction, permitting the definition of inputs and outputs, the man machine interface, and the plant specific algorithms, to proceed in parallel with the fabrication of the panels, the installation of the equipment and the generic testing thereof.

摘要： A spider assembly for supporting a corresponding rod cluster in a pressurized water reactor vessel, through which the core outlet flow passes in a predetermined direction. Each spider assembly comprises a generally cylindrical, central hub disposed in parallel axial relationship to the predetermined direction of the core outlet flow and a plurality of vane assemblies. Each vane assembly comprises means for mounting at least one rod to the assembly and at least one vane element connecting the rod mounting means to the hub. Each vane element has generally parallel, major planar surfaces disposed parallel to the predetermined direction of flow and a square trailing edge configuration which mitigates the shedding forcing function on the spider resulting from the core outlet flow thereover, while maximizing material content and thereby the strength thereof. Further, each vane element defines a plane of symmetry intermediate the major planar surfaces thereof and a leading edge cross-sectional configuration which is non-symmetrical relative to the associated plane of symmetry and preferably which is substantially uniform and defines a flow stagnation line which is off-set from the plane of symmetry. Corresponding vane elements, extending in generally diametrically opposite directions from the hub and having aligned planes of symmetry, have flow stagnation lines which are offset in a common direction from the aligned, respective planes of symmetry; alternatively, adjacent pairs of equiangularly displaced vane elements may have oppositely directed such offsets, commonly for all such pairs.

摘要： Flow induced vibration (FIV) at the slip joint between a nuclear reactor jet pump mixer and diffuser is suppressed without installing additional parts or altering the jet pump construction. The disclosed method determines a relationship between reactor operating conditions that trigger FIV and the magnitude of a mixer/diffuser transverse contact load. A mathematical analysis on a representative jet pump configuration determines the quantitative relationship between mixer/diffuser cold positions and their positions when the reactor is operating. Thus, a prediction can be made as to whether an installed jet pump will experience FIV, and the mixer and diffuser can be positioned by a mixer adjustment tool when the reactor is cold to provide the necessary operational transverse contact load. Alternatively, a contact load measuring tool directly measures the magnitude and direction of the cold mixer/diffuser transverse contact load to determine if FIV will be suppressed when the reactor is operating.

摘要翻译： 在核反应堆喷射泵混合器和扩散器之间的滑动接头处的流动诱发振动（FIV）被抑制而不安装附加部件或改变喷射泵结构。 所公开的方法确定了触发FIV的反应堆操作条件与混合器/扩散器横向接触负载的大小之间的关系。 代表性喷射泵配置的数学分析确定了混合器/扩散器冷位置与反应器运行时的位置之间的定量关系。 因此，可以预测安装的喷射泵是否将经历FIV，并且当反应器冷却以提供必要的操作横向接触负载时，混合器和扩散器可以通过混合器调节工具定位。 或者，接触负载测量工具直接测量冷混合器/扩散器横向接触负载的大小和方向，以确定当反应器运行时FIV是否被抑制。
