TRACEABILITY A SAFETY TOOL TO MANAGE THE RADIOLOGICAL HAZARD AT CERN By L. Bruno, T. Schmittler DGS-RP S. Mallon-Amerigo, M. P. Kepinski GS-ASE EDMS 1203350 IEFC Workshop, 7 March 2012

Outline 2 � Motivation Rationale to extend the existing CERN traceability system (“MTF”) to trace radioactive equipment. � Review of the extended system Design scenarios for the Traceability Radioactive Equipment at CERN (“TREC”) “Vision” of TREC at CERN New MTF features � Key figures Statistics gathered during the last technical stop Remarks about the current use � Possible improvements EDMS 1203350

Why TREC ? 3 Safety Officers findings, June 2009 � � � “The existing manual traceability system is too resource consuming. ” “Present documentation systems are not integrated: as an example, it is not easy to retrieve radiological checks (e. g. dose rate measurements. . . ) of a piece of equipment identified in MTF. ” “Trace can be lost if an equipment is shipped, leaves an experimental cavern, is centrally stored, becomes waste. ” « Visite de contrôle » of the French and Swiss Authorities, June 2010 � “Je vous demande de bien vouloir harmoniser les procédures concernant la sortie du matériel radioactif de zones contrôlées pour tous les accélérateurs et salles expérimentales du CERN (et pas uniquement pour le LHC) et mettre en place un système informatique permettant la gestion de tous les matériels sortants de ce zones. ” EDMS 1203350

Design scenarios 5 ① A technician retrieves from service a potentially radioactive accelerator component. The component has not been traced yet. Need: The technician needs RP to check the item before shipping it to a suitable workplace for maintenance. ② An RP officer finds an unidentified radioactive piece of equipment, which is abandoned in a location of the PS Complex. Need: The officer needs to label immediately the piece of equipment, measure the ambient dose equivalent rate and store the measurement result. EDMS 1203350

TREC - The vision 6 LHC Buffer Zone SPS Buffer Zone How we can manage the risk of dissemination of radioactive equipment: � Rad. Lab 1 Buffer Zone � Rad. Lab 2 � Buffer Zones Rad. Waste Buffer Zones � Provide with a buffer zone all locations at radiological risk; Intercept rad. material at the exit of each location; Trace rad. shipments between locations; Do not trace movements of rad. material inside a location EDMS 1203350

Today’s traceability at CERN 7 Hardware � � Software � � � Generic, unique, unambiguous traceability labels; LHC buffer zones equipped with a PC & 2 D barcode reader; http: //trec. web. cern. ch (simpler, type „trec“ in the browser address); Extended MTF (Infor. EAM Oracle Database & PL/SQL procedures) Functionality to create EDH transport request by TREC Support � � Trec. support@cern. ch EDMS 1203350 SIR web-based course

Some numbers 10 TREC Statistics 7 Dec 2011 - 5 Mar 2012 Remarks TREC usage: � RP Measurements requested: 2048 � RP Measurements closed: 1912 Support requests � Open/in progress: � Closed: Material measured � Total volume [m 3]: 481 � Total weight [kg]: 8 19 23119 Radioactive material identified � Total volume [m 3]: 31 � Total weight [kg]: 10335 Radioactive waste The system has been validated by extensive use. The system is robust and easy to use: users have requested help in ~1. 5% of the cases. The system can provide statistics about the production of radioactive equipment. The system can be installed for routine use in other CERN buffer zones. Contact trec. support@cern. ch Of course …There is always room for improvement ! EDMS 1203350

Work to come ? 11 Planned work… q Federate TREC with the traceability databases set up by the LHC Experiments. … and new requests ? ! q Extend TREC to manage radioactive shipments (e. g. avoiding the paperwork). q Link TREC to other databases: spectroscopy db, rad. waste db (ISRAM), warehouse manag. system (BAAN). Use TREC out of the buffer zones? use TREC inside the rad. Labs ? (i. e. integrate TREC within the Computerized Management Maintenance tools) Manage risks other than radiological ? (e. g. presence of chemical risk) EDMS 1203350

Advice to the users 12 How to best profit from traceability: � Register your components as soon as possible. Be pro-active: the sooner you register your equipment, the easier it is to trace it (the data will be in the DB already!). � Register the type of your components. If possible, group your equipment by design type: it will be easier to link material data and assembly drawings. � Capture the data at the earliest stage. As an example, it is much easier to get the material’s data when you buy the material than afterwards. Contact edms. support@cern. ch EDMS 1203350
