Ensa and Shanghai Electric sign an agreement to enhance their collaboration in the Chinese nuclear market

Maliaño, July the 4th, 2019.- Equipos Nucleares SA, SME and the nuclear group of Shanghai Electric Corporation signed an agreement to continue and expand their collaboration in the Chinese nuclear market that includes the manufacture of main components for nuclear power plants and other equipment related to spent fuel and services in plant.

In recent months both companies have been working on the definition of a renewed collaboration agreement that was finally signed at the facilities that the state company has in Maliaño. In the coming months, both will work to materialize in contracts the efforts made to date.

Ensa was represented by a delegation led by its president, José David Gomila; its general director, Rafael Triviño; its director of Projects, Miguel Ángel Andérez; its director of Business Development, María Vega and its Commercial Nuclear director, José M. Zubimendi. For its part, the Chinese delegation was headed by the vice president of SEC, Lv Yachen; the president of SENPGC, Shao Jianming; and his Commercial sub-director, Zhou Jie.

Strengthen their collaboration

The signing of this agreement strengthens, even more, the collaboration that began in the nineties. Ensa and SENPGC give great importance to this agreement, since it establishes the lines of collaboration in a common benefit and that will open up possibilities for joint development in China to explore future projects.

During the meeting, a review of the international nuclear market was made and possible joint actions were identified in order to face the current scenario.

Already last april a delegation of Spanish public companies, led by Ensa and Enusa, made a visit to China to strengthen the already existing collaboration between these countries in nuclear matters.

SEC is a Chinese multinational that manufactures electrical and power generation equipment. It is the world’s largest manufacturer of steam turbines and is also dedicated to the design, manufacture and sale of products that include, among others, power generation, transmission and distribution equipment and transformers.

Ensa successfully completed the installation of five racks at the Olkiluoto plant in Finland

Maliaño, April 12, 2019- Equipos Nucleares S.A., S.M.E successfully completed the installation of five racks in the spent fuel pools of the KPA storage building of the Olkiluoto nuclear power plant in Finland.

The Cantabrian company installed the first four racks in the plant in 2014 and this work has been recently completed with the installation of five new racks for the expansion of the pools. These last “internlock” racks, Ensa’s own design, were supplied last year and finally, they have been installed in underwater installation conditions. The works, coordinated by the owner of the Teollisuuden Voima Oyj plant and supervised by Ensa, have been executed with the tools that the company based in Maliaño had supplied in the first installation and within the established schedule.

Ensa has extensive experience in the design, manufacture and installation of fuel storage equipment among which are the racks. Since 1993, it has supplied a total of 38,941 cells that are installed in all the Spanish plants and many others in China, South Korea, Finland, Taiwan and France. All designs have been developed following the highest quality standards, according to the demands of their clients.

ENUSA and Ensa show their technological strengths in China

A delegation of ENUSA and Ensa headed by their respective presidents, José Vicente Berlanga and David Gomila, with members of their management teams, Roberto González Villegas and Rafael Triviño have visited China to hold meetings at the highest level with the Chinese nuclear sector.

It is necessary to highlight the importance of the Chinese nuclear program, with five new reactors entering into operation in 2019, after the eight that were launched in 2018, with 10 new reactors under construction at present, and with the recent authorization of the construction of four new reactors. All this implies new needs in relation to fuel production, which will probably require new factories for the CNNC group and the CGN group.

The big Chinese nuclear companies see the Spanish homonyms ENUSA and Ensa, as preferential partners in their development activities in the Chinese nuclear program and in the exit to the outside of these companies.

The Spanish leaders were received by the vice-president of the CGN and a member of the Chinese government, who confirmed the Group’s interest in strengthening the collaboration begun with Spanish public nuclear companies years ago in the spent fuel management areas, service provision, development of equipment and the expansion to the design and manufacture of fuel, dismantling and participation in R + D + i activities. The CGN Group is the largest nuclear operator in China and the third worldwide.

The CGN group is interested in the fact that ENUSA can help with the implementation of its expected fuel factory, for which they have already requested construction authorization at the Yiangjian site.

Therefore important expectations for the Spanish nuclear industry are opened not only in the fuel cycle or in the development of technology, but also in the process of digitalization initiated by the Chinese nuclear sector, and in which Spain is a benchmark, as a result of the intense work begun more than a decade ago by the Spanish nuclear industry in the digitalization of its processes to improve the quality and safety of its products. In this way, the Chinese nuclear industry tries to match other industrial sectors in its country, which have already made important advances in this area.

During this visit they visited several sites where Chinese companies have their activity.

ENUSA has had the opportunity to visit the CNNC group factory in Yibin, operated by the CJNF company of the CNNC group. ENUSA has been collaborating with this company for several years, a collaboration that has resulted in the supply of several production quality control equipment’s, and with whom there are opportunities to extend this collaboration to improve its facilities in the near future through the support in the layout of their new factory in the Yibin area.

During their stay in the Asian country, both companies have held meetings with the SNPEC engineering of the Chinese SPIC nuclear group, in charge of the execution and operation of the AP-1000 design reactors located in Sanmen and Haiyang, which has put in value the great work done by Ensa in the supply of steam generators for Sanmen and they  have manifested their firm intention to collaborate in the future with both Spanish public companies.

For its part, Ensa visited the Sanmen site, the first Ap-1000 design center that has entered into operation. During the visit, the President of the Operadora, Mr. Miao Yaming, expressed his gratitude to Ensa for the services provided by the Spanish public company with the supply of steam generators. Mr. Miao also expressed his desire to extend this collaboration to the supply of equipment for phases 2 and 3 of the Sanmen project.

On the other hand, ENUSA has taken advantage of the opportunity to extend its representation agreement with its agent in China, NUTECH, until 2023, responsible for identifying the needs of the Chinese nuclear industry, and has facilitated these meetings with the Chinese nuclear industry that translate into important commercial expectations for the Spanish company. An agreement that has been signed following the strict rules of Compliance of the public company, which ensures the transparency and legal security of commercial transactions with third countries.

The CGN group is interested in the fact that ENUSA can help with the implementation of its expected fuel factory, for which they have already requested the construction authorization at the Yiangjian site.

Therefore important expectations for the Spanish nuclear industry are opened, not only in the fuel cycle or in the development of technology, but also in the process of digitalization initiated by the Chinese nuclear sector, and in which Spain is a benchmark, as a result of the intense work begun more than a decade ago by the Spanish nuclear industry in the digitalization of its processes to improve the quality and safety of its products. In this way, the Chinese nuclear industry tries to match other industrial sectors in its country, which have already made important advances in this area.
