Maliaño, December 3, 2018 – Equipos Nucleares S.A., S.M.E has reached a new agreement with the American research laboratories of SANDIA and PNNL – with whom already collaborated in a project to measure vibrations during the transport of its ENUN 32P cask in 2017 – by which it will make available to SANDIA the 1/3 scale model of the cask, so that a series of new tests can be carried out in the facilities of the BAM research Centre, in Berlin . Ensa’s technicians will support SANDIA, PNNL and BAM through the tests that will be carried out in this Centre.
The foreseen tests are framed in the verification of the behaviour of the cask and the spent fuel for compliance with the safety requirements indicated in the Normal Conditions of Transport, which are required in the licensing processes of casks for the Transport mode, according to the current IAEA regulations .
As indicated above, the scale model to be used was built in Ensa for the tests performed under Normal Transport Conditions and Hypothetical Accident Conditions, carried out at the SANDIA facilities , to validate the design of the ENUN 32P cask and the impact limiters of all the casks of the ENUN family, checking the accelerations suffered by the cask, while in this new project the accelerations suffered by the fuel will be checked in greater detail.
Once the tests are completed, all the equipment will return to Ensa while SANDIA and PNNL will be in charge of post-processing and analysing the results obtained. This new collaboration confirms the preparation of Ensa’s technological equipment and its positioning in the research of more advanced products.

Ensa welcomes ENUSA President
Maliaño, October 22, 2018 – Equipos Nucleares S.A., S.M.E received the visit of José Vicente Berlanga, president of ENUSA INDUSTRIAS AVANZADAS, S.A., S.M.E , who was accompanied by Pablo Zuloaga, Government delegate in Cantabria.
Eduardo González-Mesones, president of the Cantabrian company; Rafael Triviño, general manager and Ángel Cosío, director of Human Relations and Corporate Social Responsibility, explained some of the most relevant aspects of the company’s activity focused on the design and manufacture of large components for the nuclear industry, spent fuel management and which provides different services in the plant covering its entire life cycle, including dismantling.
During his visit to the workshop, Berlanga was able to gain first-hand knowledge of some of the equipment currently in different stages of manufacture and showed special interest in the fuel heads of the Spanish nuclear power plants that Ensa has been supplying to ENUSA since 1998. «I have been able to verify in situ that a Spanish company such as Ensa is a technical reference in the manufacturing of components for such a demanding sector as the nuclear sector», he declared.
For its part, Zuloaga valued this meeting very positively and expressed its commitment to visit the facilities of the company based in Maliaño on another occasion and in greater detail.
Both companies belong to the SEPI Group, Ensa 100% owned and ENUSA 60% owned, a holding company that covers a total of 15 public companies directly and majority owned, with more than 74,000 professionals. It also has a supervised public foundation and minority direct shareholdings in nine other companies and indirect shareholdings in more than one hundred companies.
Maliaño, 11th October 2018.- Equipos Nucleares S.A., S.M.E participated in the 44th annual meeting of the Spanish Nuclear Society with two presentations. The first one to present its advances in the ITER project and the second one focused on the automation of the measurement of tube plate hole diameters.
Sofia Corino, in charge of the Special Projects area, presented the latest novelties related to the assembly of the ITER vacuum chamber, as well as the validation of the prototypes developed.
Her, presentation was divided into two blocks to explain, on the one hand, the scope of Ensa within this project of international importance, as well as the challenges and technical difficulties that must be overcome, among which the limitation of space and access stands out. On the other hand, she talked about the prototypes already developed and the advance of their validation on the 1:1 models.
Domingo Lima, head of Ensa’s Advanced Technology Center , spoke about «Automation of the measurement of tube plate diameter holes».
In this sense, he explained that during the manufacture of the steam generators the drilling of the Tube Plate is carried out and that the difficulty in the quality control of these holes has made necessary the development of a new system and the improvement of the methodology to make the inspection in an automated and more efficient way.
Some of the advances of this robotic system are:
– Guarantee of 100% inspection of the holes.
– Calculation of measurements in real time without further processing.
– Registration of the acquired data.
– Automatic generation of reports with all measurements and non-conformities.
– Adaptable to all types of geometries.
– Improved productivity.
– Reliability of the system.
The robotic welding system developed at the Center for Advanced Technology of Equipos Nucleares S.A., S.M.E concluded the work of the first Splice Plate set of the 1/1 model that represents the Vacum Vessel of the International Thermonuclear Experimental Reactor , which is being developed in the workshops that the company has in Maliaño, as part of the order received from Iter Organization at the end of 2012.
The main objective in this phase of the project is to design and verify that the equipment and developments carried out are suitable for the work that will later be done in the installation phase in Cadarache. One of the key activities is welding, and for this reason the validation of the robotic welding system has begun, welding the first set of splice plates that act as joining pieces between the two sectors of the 1/1 model. The method used is based on an integrated robotic system conceived in the Automatic department of the CTA for the tracking of trajectories generated from 3D scans of the pieces.
In the case of ITER, the 3D model of the splice plates is used together with the data provided by the dimensional control of the robot positions. All this information is previously loaded into the system at the disposal of the welders at the operation station, which allows the joint to be selected by its reference as well as controlling and recording the operation parameters throughout the process.
Another important aspect of the system designed, has to do with the protection gas, since the particular characteristics of the sectors, the backup gas system can only provide protection in a very localized way, so a module was included in the control system that allows to coordinate the movement of the robot with that of the backup system and thus achieve that the area covered by the gas is always below the zone of incidence of the current.
Once the first batch of splice plates has been completed, a second batch will continue which, if necessary, will allow new functions to be added to the system and new improvements to be introduced that could be identified with the aim of continuing to improve the process.
Equipos Nucleares S.A., S.M.E successfully completed the loading of four spent fuel casks in Group I of the Ascó Nuclear Power Plant in Tarragona. The casks were duly positioned in the independent spent fuel storage installation of this plant.
Loading was carried out between February and May in collaboration with Enwesa S.A., S.M.E., a subsidiary of Ensa. The forecast for 2018 for the Ascó plant is to complete the load of 2 additional units in Group II foreseen for the third quarter of the year.
The main functionality of this system is the dry storage of the fuel in the plant. The Cantabrian Company has previously manufactured this type of containers for the same site and expects to participate in future loading campaigns for the Ascó y Vandellós Nuclear Association based on its experience and satisfactory results.
