该合同由Enresa于2017年5月投标,对该单位退役的“潜伏期”提供四年的工程支持。它还包括编写技术和许可文件。

法国供应的480 MWe气体石墨反应堆Vandellós1号机组于1972年至1989年间运行。

西屋公司负责全球退役,净化,修复和废物管理的副总裁Yves Brachet表示:“这份合同是一个与在法国面临类似挑战的法国电力公司合作的机会,它还突出了我们的专业知识和我们提出的能力采用创新的退役解决方案。“

法国电力公司退役和废物管理项目总监Sylvain Granger表示:“法国有九个拆解项目正在进行中,其中六个涉及气冷反应堆,法国电力集团在这一领域拥有独特的专业知识,并有意成为新兴拆解市场的领导者。我们很自豪能够与西屋公司一起在Vandellós项目上工作,并为Enresa提供拆解项目期间开发的最佳实践。“

Enresa于1994年开始拆除Vandellós1,并于2003年退役。第二阶段拆除 - 包括拆除反应堆压力容器外的所有建筑物,系统和设备 - 已于2003年顺利完成。

没有核燃料的压力容器已经密封并将保持25年。在这个休眠期间,内部结构的放射性自然衰减。2028年左右,压力容器和所有内部结构将被移除。该网站将被完全释放。



Contract awarded for Vandellós 1 engineering support

Westinghouse and EDF will provide engineering services for the dismantling of unit 1 of the Vandellós nuclear power plant under a contract awarded by Spanish decommissioning and waste management firm Enresa.

The contract - which was put out to tender by Enresa in May 2017 - covers a four-year period of engineering support for the "latency phase" of the unit's decommissioning. It also includes the preparation of technical and licensing documentation.

Unit 1 of Vandellós, a French-supplied 480 MWe gas-graphite reactor, operated between 1972 and 1989.

Yves Brachet, Westinghouse's vice president for global decommissioning, decontamination, remediation and waste management, said: "This contract is an opportunity to work together with EDF, who is facing similar challenges in France. It also highlights our expertise and our ability to come up with innovative decommissioning solutions."

EDF's director of decommissioning and waste management projects Sylvain Granger said: "With nine dismantling projects under way in France, six of which involve gas-cooled reactors, EDF possesses unique expertise in this field and is aspiring to become a leader on the emerging dismantling market. We are proud to be working with Westinghouse on the Vandellós project and to be providing Enresa with the best practices developed during our dismantling projects."

Enresa began dismantling and decommissioning Vandellós 1 in 1994. Stage 2 dismantling - consisting of the removal of all buildings, systems and equipment outside the reactor pressure vessel - was successfully completed in 2003.

The pressure vessel, without nuclear fuel, has been sealed and will remain so for a period of 25 years. During this dormancy period, the radioactivity of the internal structures will decay naturally. Around 2028, the pressure vessel and all the internal structures will be removed. The site will then be released completely.
