摘要： A compact, unitized pressurized water reactor having a pressure vessel (3) with inner and outer walls (5, 7) which form an annularsection (9) and a central chamber. Heattrans- fer tubes (59) are provided in the annular hollow section (9) and mounted on tube sheets (35) which seal the upper portion of the annular section (9) from the lower portion thereof. Compartments (10) are formed in the lower portion of the annular hollow section by divider walls (33) and channel members (42). A core (29) is disposed within the central chamber and coolant circulating pumps (63) are provided for circulating coolant upwardly through the core (29) and through the heat exchange tubes (59) in the annular section (9) in which secondary coolant is converted to steam and discharged through openings (65) in communication with steam drums (69). The arrangement provides for a very compact structure with minimal leakage problems, all passages except for the steam pipes being contained within the reactor vessel (3).

摘要： © in a nuclear reactor pressure vessel including reactor internals with hold down spring structures and upper head region cooling passages, the hold down spring structures comprise a plurality of stacks of Belleville spring washers to provide spring load and deflection capability to hold down the reactor vessel internals. Each spring assembly includes means for passing an adjustable coolant flow to the upper reactor vessel head region in order to maintain that region at inlet coolant temperature. The spring assemblies are angularly spaced about a core barrel support flange to cooperate with coolant flow passages formed therein.

摘要： A hydro-ball in-core instrumentation system for a nuclear reactor (48, 50, 52) for measuring the core reactivity, employs detector strings (40) having radiation sensitive balls (84) spaced, threaded and fixed on each string; the opposite tip ends of each string are transportable by fluid drag for transporting the detector strings (40) from stored positions in an exterior chamber to inserted positions within the instrumentation thimbles (150, 352) of the fuel rod assemblies of a pressure vessel (50) from the bottom or top, and for return. The coolant pressure within the detector passageways is the same as that within the vessel (50). The detector strings (40) may pass through a very short bend radius thereby minimizing space requirements for the connections of the instrumentation system to the vessel and concomitantly the vessel containment structure. Improved radiation mapping and a significant reduction in exposure of personnel are realized.

摘要翻译：用于测量核心反应性的核反应堆（48,50,52）的水球核心仪表系统使用具有辐射敏感球（84）的检测器串（40），每个串隔开，螺纹并固定在每个串上; 每个串的相对的末端可以通过流体阻力传送，用于将检测器串（40）从外部室中的存储位置传送到压力容器（50）的燃料棒组件的仪表套管（150,352）内的插入位置）从底部或顶部，并返回。检测器通道内的冷却剂压力与容器（50）内的冷却剂压力相同。检测器串（40）可以通过非常短的弯曲半径，从而最小化仪器系统与容器的连接的空间要求，同时伴随着容器容纳结构。实现了改进的辐射测绘和人员暴露的显着减少。

摘要： A nuclear rector steam generating plant including a pressurized water reactor (3) with a single discharge line (5) to a steam generator (7), with the primary coolant passing through the steam generator being divided into two streams in the channel head outlet section that is divided into two subsections. Discharge nozzles on the outlet subsections direct the streams of coolant to two separate pumps (29, 31) which pump the primary coolant back to the reactor (3). Operational safety is greatly improved with this arrangement, especially for smaller one- or two-loop plants.
