Ensa successfully loads the first two ENUN 32P casks in Trillo NNPP

Maliaño, January the 24th of 2019. – Equipos Nucleares S.A., S.M.E successfully completed the loading of the second ENUN 32P cask at Trillo Nuclear Power Plant in Guadalajara. The cask was transferred to its storage position in the Individual Spent Fuel Storage Installation (ISFSI of the plant, where 2 ENUN 32P casks and 32 DPT casks, also designed, manufactured and loaded by Ensa, are stored.

With the loading of these casks, carried out in collaboration with Enwesa S.A., S.M.E, a subsidiary of Ensa, the first load campaign of the ENUN 32P casks was successfully completed and the process of starting up was completed. This process was previously initiated by the modification of auxiliary equipment and the performance of cold trials.

ENUN 32P casks, designed and manufactured by Ensa, allow the transport and storage of spent fuel. These first campaigns of loads carried out in Almaraz NNPP and Trillo NNPP suppose putting in service this cask model of the ENUN series.

During his stay various meetings were held, as well as visits to the works hops where this project is being worked on and the last two specific developments of the project were presented: Tooling for the semi-automatic positioning of splice plates in ports and the welding head for biscuits.

Ensa’s new success in ITER robot welding

Maliaño, November 16, 2018 – Equipos Nucleares S.A., S.M.E continues with success the execution of welds of components destined to the ITER project .

 

The robotic TIG welding system developed in the Advanced Technology Centre by the Automatic Unit with the Welding Development Unit, in collaboration with the personnel of the Production Welding Unit, has made possible to complete the vertical upward welds on both sides of one of the ITER sector components assigned to the Cantabrian company, obtaining magnificent results in the quality and productivity of the process in the 3 welded components.

PARTICIPANTS IN THE COROMA PROJECT hold their general meeting in Ensa

Maliaño, November 13, 2018 – The European project COROMA, in which Equipos Nucleares S.A., S.M.E participates as an end user, continues and the second anniversary of its beginning is celebrated, two working days were organized in the company’s facilities. The main objective was to expose the most significant advances of this important project whose aim is to develop an autonomous modular robot, easily programmable, safe in its interaction with humans and other machines and able to adapt to changes in its environment.

The first day was of a technical nature and served to share their experiences. In the different presentations details of their developments were shown and the operation of their modules was explained. At the end of the day, all the participants visited Ensa’s workshop and showed their interest in the processes and components it manufactures.

The second day was attended by two experts in charge of evaluating the work carried out. After the presentations of those responsible for each of the work packages and the subsequent analysis, the evaluators showed their good impression of the level reached so far in each of the sections.

In the following months, work will continue on the integration of the different modules, after which, in the last four months of 2019, final tests will begin on the applications proposed by end users.

The COROMA project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 723853.

Ensa participated in the 8th NDA Estate Supply Chain Event in Manchester

Maliaño, November 6, 2018 – Equipos Nucleares, S.A., S.M.E participated in the 8th edition of the NDA Estate Supply Chain Event held in Manchester; the most important event in Europe related to nuclear dismantling.

This fair, organised by industry for industry, provided the opportunity to establish contacts with more than 300 exhibiting companies in the nuclear industry. On this occasion, the Cantabrian company was able to share its experience in the dismantling of both Spanish plants and experiences outside Spain .

 

Ensa successfully completes the loading campaign at the Ascó II Power Plant

Maliaño, 19th October 2018.- Equipos Nucleares S.A., S.M.E successfully completed the loading of 2 casks at the Ascó nuclear power plant in Tarragona.

With this work, the Cantabrian company has completed the loading campaign this year for a total of 6 casks; 4 in group I between March and April and 2 in  group II between September and October.

In addition to the loads, Ensa received 4 new casks manufactured by the company itself, two of which were used for Group II.

Ensa participated in the SNE meeting with two conferences to present its advances in the ITER project and in the automation of the measurement of tube plate hole diameters

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.

Ensa, within a group of technologists, winner of the «Secretary’s Honor Awards – Achievement Award»

The Cantabrian company was nominated in May 2018 for an R&D project on its ENUN32P cask.

Maliaño, 04 October 2018.- Equipos Nucleares S.A., S.M.E in collaboration with other national and international technologists -Enresa and Enusa, the American laboratories: Sandia National Laboratories and Pacific Northwest National Laboratory and several South Korean organizations , has finally won the «Secretary’s Honor Awards – Achievement Award» granted by the Department of Energy of the Government of the United States of America for an R&D project to study the behaviour of spent fuel elements transported in its ENUN 32P dual-purpose, storage and transport cask, and verify the calculations made during the design.

U.S. laboratory Sandia led this international data collection test during an eight-month triathlon to quantify the accelerations and vibrations and deformations experienced by uranium oxide rods from a simulated spent fuel element during transportation by rail, ship and truck. Its analysis revealed that the accelerations and deformations were well below the resistance limit of the irradiated fuel.

The award recognizes the contribution of this equipment to the benefit of U.S. society and represents the highest non-monetary recognition that can be received.

Other entities that have received this prestigious award have been the Oak Ridge National Laboratory and NASA.
