Ensa increase its external calibrations

Maliaño, March 26th 2019-.  The Metrology Laboratory of Equipos Nucleares S.A., S.M.E is set as a reference in the world of calibration. An example of this is the constant increase of external works realized. In 2010 a hundred measurements were counted, in 2018 this figure has reached up to 600.

The cantabrian company ensure that the confidence that its clients have deposited in it is due to several factors as the direct, professional and near deal with the laboratory technicians, reflected in the results of the surveys made; to the differentiating element of its service  by calibrating what the customers need when they need it; and the increase in accreditations ENAC that allow Ensa to participate and win tenders for calibration plans of big companies as Repsol, GE, etc.

These data are supported by the good results obtained in external and internal audits and in the inter-comparisons with other laboratories.

The Advanced Technology Center of Ensa cooperate with Navantia improving the developments in the design and production of a component for a new submarine

Maliaño, March 5st, 2019. – The Advanced Technology Center of Equipos Nucleares S.A., S.M.E  , with other technologies centers as CTC, Eurocontrol and CADE, made an advisory and consulting work  to Navantia shipyard in the design and manufacturing review of one of the integrating components of the new S-80 submarines.

Through different analysis and calculations, in addition to ensuring compliance with the ASME standard, it was verified that these components of the submarine were safe for installation.

Ensa develops two news processes of protection against the corrosion of the sealing gaskets of its ENUN cask

Maliaño, March 1st 2019.- Equipos Nucleares S.A., S.M.E has developed two news alternatives for the recharge processes in the seat area of the sealing gaskets thanks to a subsidy of the line INNOVA 2017 of de Department of Innovation, Industry, Tourism of the Cantabrian government.

The main purpose of the project consists in the improvement of the productivity and competitiveness of metal casks of the ENUN family of new manufacturing in the protection of the board area against to corrosion. For that, Ensa has developed two alternatives and complementary lines thanks to the introduction of new technologies.

Therefore, Ensa has developed the robot application of weld CMT, which allow the performance of recharge the sealing gasket with a high metallurgic quality and an important rise in productivity. This is possible thanks to the improvement of the welding device, as well as the system robotization that allows covering any type of complex geometry.

Ensa received students of the intermediate level of Mechanid of Salesianos school

Maliaño, February the 26fst of 2019.- Equipos Nucleares S.A., S.M.E  received the visit of the second-year students of the intermediate level of Machined of Salesianos school at Santander.

The group was welcomed with a presentation of the company where the main products designed and manufactured and the services offered to the nuclear industry were shown.

The visit continued in the Advanced Technology Centre where they observed, among others, tensile tests and impact tests with Charpy pendulum.

The meeting finished in the factory where they could see the main components and products in differents stages of manufacturing. Also the group observed the operation of specific machines such as grinding machines, boring machines, broaching machine and the vertical lathe and it was explained to them the work carried out in the clean area.

Ensa has done a new vibration test in the Ascó nuclear power plant

Maliaño, February the 21fst of 2019.- The Automatic department of the Advanced Technology Centre of Equipos Nucleares S.A., S.M.E has made a new test of vibrations in Ascó nuclear power plant in Tarragona to verify the correct state of the reactor coolant pumps.

As a part of the framework contract that the state company with head office/headquarters in Maliaño has signed with Westinghouse for the nuclear power plants of the National Association Ascó- Vandellós group it has been made the vibration measurements of the reactor coolant pumps during the beginning of plant cycle.

With these measures it was verified the correct state of the pumps after the servicing realized during the refuelling outage and also the needed calculations were made in anticipation of a scenery where balancing is necessary. The works were developed during the pressure and temperature rise of the plant until reaching nominal values.

Ensa collaborates with the University of Cantabria and the CSIC in a project on non-destructive ultrasonic testing techniques

Maliaño, December 17th, 2018 – Equipos Nucleares S.A., S.M.E collaborated with the University of Cantabria and the Higher Council for Scientific Research in a project related to the techniques of non-destructive testing by ultrasound whose objective was that the Cantabrian company improve its training in two new generation techniques Phased Array and TOFD.

The execution of this project is translated in terms of innovation for Ensa, due to the fact that the advanced ultrasound tests can contribute to guarantee the quality of the welds in the welding station itself.

This collaboration has served to launch a new inspection technology project aimed at robotizing tests for the ITER project with which the Cantabrian company and the UC will continue working together.

The project was financed by the Ministry of Innovation, Industry, Tourism and Trade of the Government of Cantabria through the European Regional Development Fund .

Ensa participated in the Heavy Fabrication Summit (HFS2018) in Finland

Maliaño, December 12th, 2018-. Equipos Nucleares S.A., S.M.E participated in the Heavy Manufacturing Summit held at the Pemamek headquarters in Loimaa, Finland whose main objective was to make known the latest welding trends to increase quality, productivity and efficiency in heavy manufacturing.

The event was attended by over a hundred participants from companies around the world who came together to learn about the latest trends in heavy welding , recent innovations in this field and ways to increase production capacity. In addition, there were live demonstrations of six different automated PEMA welding and production solutions. Domingo Lima, head of the Center for Advanced Technology represented the Cantabrian company there.

Ensa develops a mechanized welding machine for circular joints in ITER sectors

Maliaño, December 5, 2018 – The Automatic unit belonging to the Advanced Technology Centre together with the Welding Development of Equipos Nucleares S.A., S.M.E have developed a mechanized welding machine for the accomplishment of the circular joints of the sector PS1 of ITER .

This machine has the particularity of having a rotary joint that allows continuous welding.

Ensa collaborates again with SANDIA and PNNL (USA ) and BAM (Germany) laboratories

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.
