WP1: Optimised methods for the measurement of activity in metallurgy
CMI, CIEMAT, ENEA, ITN, POLATOM, PTB, SMU, STUK
Current gamma detection systems used to monitor the steel production chain (i.e. each stage of the smelting process) differ in geometry, energy resolution, sensitivity and throughput. In addition the reference standards for these systems are either missing (replaced by mathematical modelling) or not very well characterised (i.e. they aren't traceable to the SI). This makes the comparison of results between steel companies inaccurate and subject to disputes. The disparity between national regulations and the lack of a harmonised European standard only compounds this unsuitable situation further.
Aims of the work package
The aim of this work package is therefore to assess current gamma detection systems and to optimise them and design standardised, traceable methods for the control/measurement of activity (i.e. radionuclides) in scrap loads, cast steel, slag and fumes dust discharges.
- Task 1.1: Survey of current devices/systems used for measuring activity in metallurgy (CMI, CIEMAT, ENEA, ITN, POLATOM, PTB, SMU, STUK)
- Task 1.2: Proposal of an optimised testing procedure for gate scrap monitors (CMI, ITN, SMU)
- Task 1.3: Recommendations for the basic design of an optimised spectrometric device for cast steel and slag sample measurement (CMI, CIEMAT, ENEA, ITN, POLATOM, PTB, SMU, STUK)
- Task 1.4: Proposal of a sampling and sample preparation methods for fumes dust measurement (CMI, CIEMAT, ENEA, ITN, POLATOM, PTB, STUK)
WP 2: Development and characterisation of reference standards for the metallurgical industry
PTB, CEA, CIEMAT, CMI, ENEA, IFIN-HH, JRC, POLATOM, SMU
Currently there is a lack of reference materials and calibration standards for radioactivity monitoring. Therefore, this JRP will go beyond the current state of art by designing and developing prototype reference materials and calibration standards for radioactivity monitoring at each stage of the smelting process e.g. slags, filters for fume dust, cast steel probes. These reference materials should ensure the reliable and SI traceable measurements of radioactivity and the specific radionuclides to be used in this JRP are 60Co, 90Sr/90Y, 137Cs, 192Ir, 226Ra and 241Am.
Aims of the work package
The aim of this work package is to develop reference standards to enable the accurate and traceable measurement (e.g. via radio-assay) of materials relevant for the metallurgical industry (e.g. cast steel, slag and fume dust).
The reference materials will contain those radionuclides that are known as potential contaminants (Co-60, Cs-137, Ir-192, Ra-226, Am-241, Sr/Y-90) in cast steel, slag or fume dust and single radionuclide reference sources will be preferred. For each type of reference standards at least two activity levels of radionuclides will be produced, in order to achieve a low uncertainty value when calibrating detector systems. They are:
- One set with activity levels in the order of 1 Bq/g, which corresponds to current clearance levels for radioactivity and
- One set with higher activity values in the order of 10 Bq/g to 100 Bq/g. The exact values will depend on the information provided in the questionnaires in task 1.1 as this will indicate the minimum activity necessary to calibrate the detector systems in a reasonable time.
The target uncertainty value for measuring activity in the reference standards is less than 5%.
As well as producing the reference standards in this work package, JRP-Partners involved in WP2 will be required to produce samples of the reference standards for the inter-comparison in WP3 task 3.3. The inter-comparison will require one sample for each of three groups of reference standards developed in WP2 (i.e. real cast steel, slag and fume dust reference standards):
- One sample for cast steel reference standards contaminated with radionuclide Co-60 with clearance level activity of 1Bq/g;
- One sample for slag reference standards contaminated with radionuclide Ra-226; with higher activity values (as defined above)
- One sample for fume dust reference standards contaminated with radionuclide Cs-137 with higher activity values (as defined above)
For each sample, sufficient copies will be produced by the JRP-Partners in WP2 for distribution to every JRP-Partner participating in the inter-comparison in WP3 and to those JRP-Partners who intend to reproduce and offer them commercially in the future

WP 3: Characterisation of WP1-recommended measurement geometries using WP2 reference materials, Monte Carlo simulations and inter-comparisons
CMI, BEV/PTP, CEA, CIEMAT, ENEA, IFIN-HH, IJS, ITN, JRC, MKEH, POLATOM, PTB, SMU, STUK
Aims of the work package
The aim of this work package is to characterise the measurement geometries recommended in WP1 using the reference standards produced in WP2. To do this, this work package includes:
- A task developing a validated Monte Carlo model/simulation of the spectrometric device proposed in task 1.3
- A task on the calculation of true coincidence summing corrections for cast steel, slag and fume dust samples,
- An inter-laboratory comparison of activity measurements of the cast steel, slag and fume dust reference standards produced in WP2. The goal of the inter-comparison is to confirm the traceability of the reference standards and to determine the range of sample geometries (e.g. shape, density and elemental composition) that the Monte Carlo models needed to encompass.
- Task 3.1: Development of a validated Monte Carlo model of the device proposed in task 1.3 (ITN, all JRP-Partners except IJS)
- Task 3.2: The calculation of true coincidence summing corrections for cast steel, slag and fume dust samples (CMI, CEA, CIEMAT, ENEA, IFIN-HH, ITN, JRC, PTB, SMU, STUK, MKEH)
- Task 3.3: Inter-laboratory comparisons of WP2 reference standards (JRC, all JRP-Partners)
WP 4: Production of an optimised spectrometric device for the measurement of cast steel, slag and fume dust samples
(CIEMAT, CMI, ENEA, PTB, SMU)
The current state of the art for radioactivity monitoring in smelting factories are gamma detection systems that use plastic or crystal scintillator detectors. These systems are commercially available but vary in their technical approach, which result in differences in geometry, energy resolution or sensitivity levels of their measurements, making difficult to compare their performance and results.
To address this issue, JRP IND04 will analyse commercially available gamma detection systems and their technological components (e.g. detectors, measurement cells, acquisition and data processing modules). The JRP will then select the optimal measurement configurations and specific procedures
Aims of the work package
The aim of this work package is to specify in detail and build on the recommended basic design of an optimised spectrometric device for the measurement of cast steel, slag and fume dust samples produced in tasks 1.3 and 1.4 and to produce a full design for the device. The design will be adapted to the dimensions and compositions of typical probes used in smelting facilities. The goal is produce a device with enhanced efficiency and reliability over those currently existing and its specific values and advantages will be determined from WP1 results.
Two prototype devices from the same design will be constructed in this work package. They will then be evaluated at end user facilities as part of WP5, and subsequently used for end-user demonstrations in WP6.
- Task 4.1: Design of an optimised spectrometric device for measuring cast steel, slag and fume dust samples (CIEMAT, CMI)
- Task 4.2: Construction of two prototype spectrometric devices from the design in task 4.1 (CIEMAT, PTB, ENEA)

WP 5: Evaluation of the prototype spectrometric devices produced in WP4 and the methods developed in WP1 at end-user facilities
IJS, BEV/PTP, CIEMAT, CMI, ENEA, IFIN-HH, ITN, JRC, POLATOM, PTB, SMU
Aims of the work package
The aim of this work package is the evaluation of the prototype spectrometric devices produced in WP4 using the methods developed in WP1 at end-user facilities (i.e. smelting foundries). As stated in WP4 the goal with the prototypes is to produce a spectrometric device with significant advantages over existing probes in terms of detection efficiency and reliability, as mentioned in WP4. To be able to determine this and evaluate whether the prototype spectrometric devices and methods developed in WP1 are better than the current state of the art (i.e. for measuring activity in scrap metal, slag, fume dust and cast steel) precise evaluation criteria need to be developed. Measurements will be performed at more than one end-user facility in order to demonstrate reproducibility.
- Task 5.1: Definition of the evaluation criteria for the spectrometric prototypes. (ENEA, IJS, CIEMAT, PTB, SMU, BEV, POLATOM, IFIN-HH)
- Task 5.2: Calculation of correction factors for the spectrometric prototypes produced in WP4 based on the end-user facilities used in task 5.3 (CMI, CIEMAT, IFIN-HH, ITN, JRC, POLATOM, PTB)
- Task 5.3: Evaluation of the spectrometric prototypes produced in WP4 and the methods developed in WP1 at end-user facilities (IJS,BEV,CIEMAT, CMI, ENEA, PTB, SMU)
WP 6: Creating impact
Aims of the work package
The aims of this work package are:
- To share the results of the JRP with the wider metrological and end user community,
- To promote uptake of the results by end-users
- To enable feedback from the stakeholders and end-user community to be incorporated in to the JRP.
- Task 6.1: Stakeholder and End-user group (CIEMAT, all). The aim of this task is to set-up a stakeholder and end-user group, with JRP supporters and collaborators as its core members. This group will be open to any EU Enterprise that has an interest in improving the measurement of radioactivity, particularlywithin metallurgy and so its size is expected to grow during the JRP.
- Task 6.2: Publications (papers and conference presentations) (PTB, all). The aim of this task is to disseminate the JRP results through publications in peer-reviewed international scientific journals and at national and international conferences.
- Task 6.3: Input to Standards & Regulation(CMI, all). The aim of this task is to disseminate the JRP results to National and European technical committees/working groups and thereby input into standards and regulation.
- Task 6.4: JRP website (CIEMAT, all). The aim of this task is to setup and operate a JRP website for dissemination of JRP results and to support the communication between members of JRP-consortium. CIEMAT with the help of BEV will develop and host the MetroMetal website to enable supporters, collaborators and all JRP-Partners to remain informed on the progress of the JRP.
- Task 6.5: Demonstration of the prototype spectrometric devices (WP4), the reference standards (WP2) and methods developed in WP1, at end-user facilities (IJS, CIEMAT, SMU, BEV, ENEA, IFIN-HH, POLATOM, CMI). The aim of this task is to demonstrate the performance of the prototype spectrometric devices (WP4), using the reference materials developed in WP2 and the geometries and methods developed in WP1, at end-user facilities across Europe.
- Task 6.6: JRP workshops (CIEMAT, all). The aim of this task is to organise annually a MetroMetal workshop for the general dissemination of JRP results.
- Task 6.7: Exploitation Plan (BEV, all). Intellectual Property (IP) generated in this JRP will be exploited / protected in line with the `JRP Consortium Agreement'. The JRP-Consortium will analyse the possibility to exploit the prototype spectrometric devices, reference sources, correction factors and methods developed under WP1, WP2, WP3, WP4 and WP5.
WP 7: JRP management and coordination
The JRP-Coordinator is the permanent reference point for the project for both the JRP-Partners and EURAMET e.V.
Management and coordination of the project is done by:
The JRP-Coordinator, who represents the CIEMAT and the Project Management Board (see below) and will be the point of contact for the JRP for both the JRP-Participants and EURAMET e.V.
TheProject Management Board (PMB):
- Composition: The PMB will consist of the JRP-Coordinator and the six other WP leaders. The PMB will be chaired by the JRP-Coordinator. If necessary, the PMB will invite technical experts into the PMB to help validate technical decisions.
- Function: The PMB acts as the ultimate decision making body of the JRP. The PMB will monitor the JRP progress and will determine its strategic direction. The PMB will be in charge of the high level management of the JRP, addressing all the administrative, contractual and financial matters. It will take all important decisions related to the contractual execution such as: contract changes or re-negotiation, reallocation of works, responsibilities and man-power between contractors, settlement of problems or differences between contractors.
- Meetings: The PMB will meet at least once a year for a one day meeting, prior to the general project meetings. Further meetings, if necessary will be scheduled by the JRP-Coordinator. A specific area will be reserved on the JRP website for the use of the PMB.
- A Kick-off meeting will be held at the start of the JRP to ensure that all JRP-Participants fully understand the objectives of the JRP and their contribution to it. It will be an important meeting, as it will provide an opportunity for all the JRP-Partners to meet and to unify them around a common set of goals.
- A General Project Meeting to be attended by all JRP-Participants or their representatives will be held once a year, for a period of two days. Major technical and scientific results and advances will be presented and reviewed, and compared with the planned programme. The members will be consulted on major decisions to be made by the PMB and be able to formally request particular actions to be taken, which the PMB must respond to.
- The Final Meeting to be attended by all JRP-Participants will feature an evaluation session, where the project impact is evaluated and the final report concluded.
