  1. APR’04 UNECE Group of Experts on Monitoring of Radiologically Contaminated Scrap Metal Presented by: • Alvaro Rodríguez Martínez (Spain) IEC-BIR Chairman Spanish Scrap Monitoring Protocol

  2. PROTOCOL ORIGINS • On June 1998 one Cs 137 source is smelted by Acerinox (Cádiz) with an adverse national and international publicity. • The Government decides to create a dialogue forum with the different public and private stakeholders in order to analyse the problems and seek possible solutions. • During 18 months this group discussed different alternatives. The 2th November 1999 the Spanish Protocol on Radiological Surveillance of Metal recycling (“The Protocol”) is signed.

  3. PROTOCOL SIGNATORIES On the First moment: • Administration • MINER, CSN, M. of Infrastructure and ENRESA • Industrial sector • Steel Utilities Association (UNESID) • Metal Recovering Association (FER)

  4. PROTOCOL SIGNATORIES (Cont…) On a second moment: • Industrial sector • Aluminium Utilities Association (ASERAL) • Lead Utilities Association (UNIPLOM) • Cooper Utilities Association (UNICOBRE) • Unions • Unión General de Trabajadores (U.G.T.) • Comisiones Obreras (C.C.O.O.)

  5. POSITIVE ASPECTS OF THE PROTOCOL • Every signatory of the Protocol gives and receives something from the Protocol. • It is voluntary. • It is the result of a very long negotiation and conversation. • It promotes the common knowledge of the problem and the possible solutions. • Shared costs. • Recovery Plants and Smelters are “Collaborators of the system”, and not “Criminals that have to be persecuted”. • Existence of mechanisms of revision  “We learn from the mistakes”.

  6. COMMITMENTS OF THE PARTS • MINER : • To create and maintain the Register of Collaborators and communicate registrations • To grant a generic transfer authorisation of radioactive material detected from the facility to ENRESA • To govern special interventions in case of big accidents with contamination • CSN: • To issue (generic or case by case) safety guidance • To inspect surveillance systems • To set up radiological criteria • Investigation and Exemption levels (NI, NE) • To inform plants and ENRESA on applicability of the Protocol • To promote training activities • Direct intervention if needed

  7. COMMITMENTS OF THE PARTS (cont…) • ENRESA: • To give technical advise • To collaborate to re-export radioactive material • To dispose of radioactive material • To collaborate in training activities • To sign a specific agreement with the facilities • M. of Infrastructures • To require radiological surveillance certification to authorise scrap unloading in the Spanish harbours • To inform CSN in case of event

  8. COMMITMENTS OF THE PARTS (cont…2) • Commitment of the facilities • To install, maintain and operate a surveillance system in each facility • To surveille radiation level in scrap and processed materials • To take appropriate measurement to avoid radiological risks • To require radiological surveillance certification from supplier • To inform CSN on each relevant detection event • To sign an agreement with ENRESA • To collaborate in training activities

  9. HOW THE PROTOCOL WORKS (Part 1) Steel Facility Certifi- cation Imports Melting sample National scrap Radioactive material Scrapyard CSN expert inspection

  10. HOW THE PROTOCOL WORKS (Part 2) • To survey all scrap and processed materials • To immobilise shipments and to stop process if investigation levels (NI) have been exceeded • To require a UTPR services if the event occurs in the process • To investigate shipments and processes where NI have been exceeded • To segregate, characterise, and isolate radioactive material if exemption levels (NE) have been exceeded • To inform CSN if NE have been exceeded • To guard safely radioactive material until ENRESA taking off • To manage re-sending abroad radioactive material, if applicable

  11. CONCLUSIONS OF LAST 4 YEARS • 980 radioactive materials segregated and well managed. • 83 radioactive sources. • 37 small sources (non very important) • 46 relevant sources. • 75 facilities in the Protocol. (14.000.000 Tons per year are checked at least once). In the Protocol are: • All the steel smelting plants. • Most of shredding plants • Some other scrap yards, whilst • Other non ferrous plants are coming. • The number of sources grows with the time (more expansion of the Protocol more sources founded)

  12. Thank you very much for your attention
