Abstract
一种用于稠油热采具有铀氢锆点燃区的双区压水堆，其特征是具有含浓缩铀的铀氢锆细棒元件的点燃区和天然二氧化铀棒状元件的再生区的双区稠密水栅堆芯。本发明具有固有安全性，体积小，重量轻，热功率大。在稠油热采时，安置在地面下，既经济又安全。
Description
本实用新型属于核反应堆领域。
用于稠油热采，用于稠油热采，具有铀氢锆(燃料—慢化剂)元件“点燃区”的双区压水堆在已有技术文献中未见报导，中国专利CN1064170A“脉冲堆”为铀氢锆粗棒元件的池式实验堆；中国核动力研究院1994年8月在《核动力工程》第15卷第4期发表了“固有安全一体化UZrHx动力堆1NSURE—100初步研究”，报导了一种整个堆芯利用含高加浓铀的铀氢锆细棒元件的动力反应堆，上述二种全铀氢锆元件反应堆均不能为稠油热采提供温度、压力足够高的蒸汽，此外上述二种反应堆高加浓铀燃料初装载量大，燃料费用高。
本实用新型的目的在于提供一种具有安全性，能经济地提供用于稠油热采的高温，高压蒸汽的小型压水堆。
本实用新型由反应堆压力壳，包括点燃区和再生区的双区堆芯，堆芯筒体，支承，控制棒，测量仪表组成，其特征在于所述的点燃区采用含同位素浓度为10-20％浓缩铀的铀氢锆芯体不锈钢包壳的细棒元件，上述棒状元件呈三角形稠密排列，元件间隙为1-1.5毫米，再生区为天然二氧化铀、锆—4包壳棒状燃料元件，呈三角形排列的稠密水栅，栅元内慢化剂水与燃料芯体体积之比为0.50-0.83。反应堆一回路设备(包括点燃区和再生区的堆芯)“一体化”布置在不锈钢压力壳内，压力壳直径为1-1.5米，高度4-6米，二回路直流蒸汽发生器内产生131-169大气压，330℃—350℃，干度大于80％的水蒸汽。在稠油热采时，本发明安装在油田地面下的有辐射屏蔽层的深水池内，燃耗寿期超过2年，燃料卸出后，压力容器连同内部设备可整体由拖车移到他处，装料后继续使用。
本实用新型的优点：
1、由于采用了含高浓缩铀的铀氢锆元件稠密水栅点燃区堆芯，具有大的瞬发负反应性温度系数而形成固有安全性，同时为采用天然铀稠密水栅再生区提供了条件。
2、采用了天然二氧化铀棒状元件的稠密水栅再生区，充分利用了天然铀燃料，又有助于点燃区加浓铀燃料的燃耗的加深，明显地降低了燃料成本，又保证了装置小型化。
3、本实用新型热功率5-20兆瓦，为稠油热采提供了足够温度、压力的蒸汽，其温度330～350℃，压力相应为131-169大气压。
总之：本实用新型安全，体积小，重量轻，移动方便，成本低，在稠油热采方面具有较高的使用价值。
图1为本实用新型一回路在压力壳内布置的C-C纵剖面示意图。
下面结合附图进行详细描述：不锈钢压力壳1高度为4-6米，外直径1-1.5米，压力壳上腔有足够体积的空间，利用蒸汽和加充的氮气实施自稳压，不锈钢的“点燃区”筒体2把压力壳内空间分为内、外两区。直流蒸汽发生器3布置在“外区”上半部环形空间里，悬挂在压力壳壁上，其底部距离在“外区”下半部的“再生区”4的顶部1米左右。“再生区”由天然(二氧化)铀芯体，锆-4包壳的棒状元件，按三角形紧密排列成的稠密水栅组成，其组体座落在堆芯下支承板8上，(二氧化)铀棒芯体直径0.843-2.0厘米，锆-4包壳厚度为0.6-0.7毫米，再生区内紧贴“点燃区”筒体处(水温较低)安装六个Y字形控制棒5，棒内含碳化硼吸收体，外有不锈钢包壳。“点燃区”筒体上、中段为其导向组件提供横向定位，在压力壳内壁和再生区组体之间间隙中再安装六个硼钢片状控制棒7，既作调节控制棒，又能在其插入时减少压力壳的辐照。堆芯“点燃区”6在筒体内区，座落在和筒体下端固结的下支承板上，点燃区内有含可燃毒物铒或钆的高加浓油(浓缩度为10-20％)铀氢锆细棒元件，其芯体直径12.8毫米，外有Φ13.7×0.4毫米不锈钢包壳，其上焊有不锈钢定位丝(直径1-1.5毫米)。元件棒呈三角形紧密排列，形成稠密水栅，为方便卸装和临界安全，点燃区由几个组件组成。冷却水通过双区堆芯，形成双流程：冷却水从直流蒸汽发生器一回路出口处，向下流入“再生区”，在下腔改变流向，流入“点燃区”，由下而上，出堆芯后延“点燃区”套筒向上，进入直流蒸汽发生器上部内侧面入口。直流蒸汽发生器二回路出口蒸汽压力为131～169大气压，蒸汽温度330～345℃，干度大于80％。
