中国广核团体“尖峰方案”科研项目-----三废零碎蒸发塔和脱气塔要害技能研讨

 

  三废零碎蒸发塔和脱气塔是核电站废液处置零碎(TEU)和硼接纳零碎(TEP)中的要害设置装备摆设。脱气塔将反响堆冷却剂中的氢气、氮气和放射性气体脱除;蒸发塔对颠末除气的冷却剂蒸发处置,别离成反响堆级的补给水(蒸馏液)和硼酸溶液(稀释液)。现在,大亚湾和岭澳核电站的蒸发塔和脱气塔设置装备摆设均由法国某公司成套提供,由于这两个要害设置装备摆设技能庞大,触及的技能困难多,因而国际研制单元随便不敢涉足,其严峻障碍我国核电设置装备摆设国产化程度和进度。

  为冲破技能瓶颈,中国广核团体科研专项“尖峰方案”特此立项——“三废零碎蒸发塔和脱气塔要害技能研讨”,由中科华核电技能研讨院无限公司担任构造科研攻关。

  南京玖玖彩票金属配备工程株式会社承当了蒸发塔单位的设计、制造、调试等整套建立任务,并顺遂经过中广核团体的验收。

  本课题旨在针对制约在役或在建的核电站塔器设置装备摆设停止技能研讨和科研攻关,冲破外洋技能把持,低落新工程电站的建立本钱,完成设置装备摆设或零碎的国产化,终极构成自主知识产权,进一步提拔自主品牌着名度和中心竞争力。

  Evaporation tower and degassing tower are the key equipments in waste treatment system (TEU) and boron recovery system (TEP) in nuclear power station. Degassing tower is used to remove hydrogen, nitrogen, and radioactive gases from the reactor coolant. Evaporation tower is used to evaporate the coolant after degassing into reactor-grade make-up water (distillate) and boric acid solution ( concentrated solution). Currently, the complete sets of evaporation tower and degassing tower of Daya Bay Nuclear Power Station and Ling Ao Nuclear Power Station are provided by a French company. Since complex technologies and technical problem of these two key equipments, development organizations in domestic easily dare not to tread. And the domesticization level and progress of nuclear power equipments has been seriously hampered.

  To break the technological difficulties, scientific research program "Rush Plan"——"the research on the key technologies of evaporation tower and degassing tower in waste system" is hereby set up by CGNPC. Central China Nuclear Power Technology Research Institute is responsible for organizing scientific research.

  DUBLE has undertaken the design, manufacturing, debugging and other complete building work of evaporation tower unit and has passed the acceptance of CGNPC successfully.

  This topic aimed at technical and scientific researching of restrictive towers and equipments of in service or under construction nuclear power plants to break the monopoly of foreign technology, reduce the construction cost of new project power plant, realize the domestication of equipment or system, and ultimately form the proprietary intellectual property rights and further enhance the own brand and core competitiveness.
