Ensa finished successfully the test developed with the mockup of its ENUN 32P cask by the German Institute B.A.M

Maliaño, February 7th 2019. – Equipos Nucleares S.A., S.M.E has finished successfully all the activities in the 1/3 mockup of its ENUN 32P cask at the facilities of the German Institute B.A.M with the American laboratories of SANDIA and PNNL.

Two drop tests were performed from 30 cm height, in horizontal position with different orientations of its basket, on non-deformable surface that show the postulated scenarios  according to normal conditions of transport, at the regulation transport of radioactive material.

The cask was instrumented with 51 accelerometers located in the body of the cask, in the basket, at 11 of the fuel elements and also at the contact surface in the floor. SANDIA laboratories are in charge of the post-processing of the results, and PNNL of the modelling of the system through two elements finite codes.

The project is part of a series of tests and simulations that the state company located in Maliaño, SANDIA and PNNL have been carrying out for many years, to study in detail the behavior of spent fuel assemblies during postulated mechanical processes in the transport regulation of radioactive material for standard conditions and hypothetical accident conditions.

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 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.
