3. LOCATION

4. PO’ RIVER

5. DECOMMISSIONING OF THE TURBINE BUILDING AND TURBINE ANNEX DECOMMISSIONING OF 6.000 TON OF EQUIPMENT, STRUCTURES, PIPES, TANKS INSIDE THE TURBINE BUILDING DECONTAMINATION OF 1.200 TON OF RADIOACTIVE MATERIAL RUNNING TIME: 30 MONTHS

6. LONGITUDINAL TURBINE BUILDING SECTION

7. CERTAIN AREAS IN DETAIL

8. DETAILED DESIGN FOR EACH AREA Identification of the lines and facilities to preserve Identification of the SPOOL Dismantling sequenze Choice of the cutting techniques Procedures for components removal Materials handling

9. EQUIPMENT AND LINES TO PROTECT

10. TRACEABILITY OF COMPONENTS “SPOOL IDENTIFICATION”

11. CUTTING TECHNOLOGY CHOICE

12. DISMANTLING SEQUENCE 1.Electrical systems (boards, conduits and possibly cable conduits) 2.Electric Motors, servo-motors 3.Carpentry and civil structures 4.Line pipe and components 5.Supports and cushions

13. Cutting technologies to reduce risks

14. COMPONENTS REMOVAL

15. MATERIALS HANDLING

16. DISMANTING SEQUENCE PROCEDURES Processing flowchart AREA PROJECT ( SPOOL, WEIGHTS,ELIMINA TION MODE/HANDLING ) SOGIN APPROVAL SOGIN VERIFICATION ( SPOOL, PLANTS TO PRESERVE ) DISMANTLING DECONTAMI- NATION TBA, TBC, TBE TBD (NON CONTAMINATED) CONTROL 100% CONTROL 10% ALIENATION

17. DISMANTLING OF THE AREA COMPONENTS Results Effective production lower than expected

18. PROBLEMS RUNNING THE SYSTEM (creating spool, “physiological” times of the system, understanding the implementation procedures) RESTRICTIONS INTRINSA TO THE SYSTEM  IMPROVEMENT OF THE NATURAL HEALTH CONTROL PROCESS  IMPROVEMENT OF THE MATERIAL HANDLING PROCESS

21. EFFECTS ON PRODUCTION

22. WORKING PROGRAMME

23. RESULTS

24. LABOUR USED

25. CONCLUSIONS 1.Extreme design at all stages of intervention 2.Training of employees 3.Creation of new technologies and working procedures not needed until now on traditional field 4.In the order of magnitud the decommissioning and demolition costs are not comparable 5.The decommissioning is not a variant of the demolition work but a real industry that requires expertise and skills.
