AMALIA, assessment of nuclear power plants core internals (EMMA)

Oct 20 2021
Feb 01 2022

The AMALIA laboratory was built and it is operated in order to provide tools to study the effect of environment on the mechanical and corrosion performance including life assessment and qualification of structural materials for present and next generation of nuclear systems. It includes test machines and auxiliary equipment for corrosion and environmentally assisted cracking testing for various types of test specimen. In support, 3D profilometry, x-ray tomography, Scanning Electron Microscopy (SEM), microstructural analysis and data management tools can be offered.

AMALIA is situated at the Joint Research Centre in Petten (the Netherlands), consists of 5 water loops for providing and analysing water for AMALIA autoclave test facilities. The water loops include:

  • State of the art water chemistry sensors such as Conductivity, pH, dissolved oxygen and hydrogen sensors.
  • Low and high pressure pump including the back pressure regulators and pulsation dampeners to provide water circulation and needed water pressure for test facilities.

Priority topics of AMALIA

  1. Safety and reliability of nuclear components for current and future nuclear systems
  2. Support to the development and adaptation of European Codes and Standards
  3. Development of advanced test methods for material characterization
  4. Characterisation of mechanical properties of candidate and new corrosion-resistant high-temperature materials, incl. surface modifications and welded joints
  5. Prediction of design life of new materials, remaining life of service-exposed materials including welded joints subjected to operational conditions by mechanical tests, modelling and microstructural analysis. 
  6. Characterization of tensile and creep properties using standard and sub-size specimen and small punch tests
  7. Characterization of ageing effects for key material properties.

Definition and conditions of access

Access to the research infrastructure is granted on the basis of Access Units. For AMALIA, the Access Unit is an 'AU' and corresponds to 1 day of continuous operation.

The typical duration of a test programme is 1-60 AUs. The latter is representative for performing a SCC initiation tests in high-temperature and pressure water with controlled oxygen or hydrogen content. Up to three SCC initiation tests can be performed simultaneously in Autoclave 4. Otherwise only one test per autoclave is usually under way. Moreover, corrosion tests (without any load) can be conducted as well with AUs extending to 60 AUs.

  • Estimated total number of Access Unit allocated to the call: 60 AU
  • Average number of Access Unit per Project: 30 AU (corresponding to mechanical and corrosion tests in six Autoclaves) 
  • Estimated costs excluding consumables and expenses:
    • Research infrastructure operated by JRC staff: 0€ / Day
    • Research infrastructure operated by users: Yes

It is expected that the User Institutions provide the test specimens.

Support of users for travel and subsistence

The JRC may provide a financial or in-kind contribution to support Users to cover their costs of travel and subsistence (T&S) related to the User Stay Days, subject to the availability of funds, personnel and other resources to Users from User Institutions located in an EU Member State or country associated to the Euratom Research Programme (only Switzerland and Ukraine).

A User Stay Day is a day of physical presence of a User at the concerned Research Infrastructure for Access related to the User Access Project. A User Stay Day counts as a registered entry to the JRC site where the Research Infrastructure is located.

  • Estimated total number of User Stay Days for short- term stays eligible for T&S allocated to the call: 40
  • Estimated total number for long- term stays (months) eligible for T&S allocated to the call: 16

Long term stays are primarily for students and have a duration of at least 1 month. They are typically 3 to 9 months for Karlsruhe, and 1 to 6 months for Petten and Geel.

The Lead Used is welcomed to fill in the User travel and subsistence form and send it to by the closing date of the call. For more information the Lead User may contact the JRC Research Infrastructure at

Allocation of intellectual property rights

  • The JRC and the entitled party (person or organisation that has been granted access) become co-owners in equal shares of all raw data, treated data and documentation data developed with respect to the access.

or, if requested by the user or when users run the research infrastructure

  • Raw data, treated data and documentation data will be solely owned by the entitled party. The JRC receives a non-exclusive, royalty free, unlimited and world-wide license to use (meaning in particular to access, exploit, adapt, merge, translate, copy and store) the raw data, processed data and documentation data in all fields of exploitation. Where relevant, the license will include all the data / information necessary to replicate the tests.
