Ensa receives the Certificate of Compliance of the ENUN 24P cask in Spain

/en /por

Maliaño, October 31, 2017. – Equipos Nucleares S.A, S.M.E. has received the approval of the MINETAD for the design of its ENUN 24P cask for the transportation of spent nuclear fuel. With this approval, the licensing process in Spain of the cask is concluded.

The design of the ENUN 24P allows the storage and transportation of up to 24 non-damaged used PWR fuel by road, rail and sea. Ensa has already manufactured a unit of this model, which has already been delivered to the Daya Bay plant in Shenzhen – China.

This license approval is a milestone for the Spanish nuclear industry, since  the ENUN 24P is the first cask licensed in Spain that allows the transportation of high burnup fuel . Additionally, the ENUN 24P increases the list of self-designed casks already licensed by Ensa, adding to ENUN 32P and ENUN 52B.

The Energy Policy and Mines General Directorate of MINETAD, in accordance with the favorable report issued by the CSN and, as a result of the evaluations carried out, agreed to approve this design for «complying with the requirements for type B packages as per the regulations of the International Atomic Energy Agency and the Spanish regulations on the transport of dangerous materials «.

Ensa is currently providing support to its customer URC for the design validation process by the Chinese Nuclear Regulator Authority . This validation will presumably  enable URC to carry out the first commercial high burnup fuel transportation in China.

Ensa belongs to the SEPI Group, a corporate holding company that comprises a total of 15 Spanish public companies directly and majority owned, with a workforce of almost 73,000 professionals. SEPI is also a shareholder of the Spanish Broadcasting Corporation , and has a public foundation and direct minority interests in nine other companies and indirect in more than one hundred companies.

Vacuum Vessel: first parts manufactured by ENSA completed

/en /por

ENSA , as part of the AMW consortium, has achieved a key F4E milestone: the machining of two inner shell plates – the first pieces to be manufactured at ENSA – has been completed. These plates will make up the longest of the segments of the ITER Vacuum Vessel’s sector 3, and measure each 6 metres long, 1.5 metres wide, and has a thickness of 60 millimetres. The plates are made up of the special ITER grade stainless steel. The long length of each plate has entailed a number of challenging steps involving cleaning; cutting and machining of holes which will house the so-called flexible housings ; as well as carrying out a wide variety of inspection techniques in order to detect the presence of defects, characterise findings, and measure without causing any damage to the plates themselves . What makes this work additionally challenging is the fact that the flatness tolerance is very tight – only a 0.4 mm variatio

n in 6 metres is permitted. With the right techniques, the necessary flatness tolerance for the plates has been achieved, even despite that the longer the length of the piece, the more difficult it is to attain the same overall flatness.

“This milestone achievement shows the commitment of ENSA as part of the AMW consortium to the delivering Europe’s Vacuum Vessel contribution and its key role in the success of the Vacuum Vessel manufacturing”, says Rafael Treviño, Director General of ENSA.

“F4E is pleased with ENSA’s performance: they keep their commitment whilst anticipating and mitigating issues. ENSA has lived up to its reputation of being one of the best European companies in the nuclear field”, says Francesco Zacchia, Project Manager for F4E’s Vacuum Vessel Team.

The European Commission approves Ensa its MEACTOS project .

This project, which lasts four years, aims to improve the reduction of residual stresses and the stress effect of cracking corrosion in steels from the perspective of microtensions and surface cracks induced by machining and treatments that can be given superficially to the pieces to alleviate them or to avoid their appearance.

In addition to the general objectives of the project, Ensa expects to obtain information on the possible replacement of cutting fluids and oils by refrigeration with cryogenic technology , and to acquire the necessary qualifications to carry out processes that have to do with this surface induction tension effect in machining.

In its «passion for improvement», for Ensa it´s important work with the most advanced technologies, such as cryogenics or CO2 cooling and introduce the latest technological advances in its manufacturing processes.

Led by CIEMAT and within the framework of Research and Innovation Program of the European Union Horizon 2020 the Cantabrian Company has participated with AREVA, EDF and Nuclear AMRC.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 755151.
