Outline
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

Why TREC ?
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.”

Choice of the hardware and software tools
Pilot users from BE-ABP-SU, EN-STI and TE-CRG
Pilot tests in the LHC buffer zones SD1 with on site support
Systematic use for ALL material in transit in SD1 and SD2

Design scenarios
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.

TREC - The vision
LHCBuffer Zone
How we can manage the risk of dissemination of radioactive equipment: 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

Today’s traceability at CERN
Hardware Generic, unique, unambiguous
traceability labels; LHC buffer zones equipped
with a PC & 2D barcode reader; Software
http://trec.web.cern.ch(simpler, type „trec“ in the browser address);
Extended MTF (InforEAM Oracle Database & PL/SQL procedures)
Functionality to create EDH transport request by TREC

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 [email protected]
Of course …There is always room for improvement !

Work to come ?
Planned work…
Federate TREC with the traceability databases set up by the LHC Experiments.
Extend TREC to manage radioactive shipments (e.g. avoiding the paperwork).
Link TREC to other databases: spectroscopy db, rad.waste db (ISRAM), warehouse manag. system (BAAN).
… and new requests ?! 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)

Advice to the users
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.

Some definitions
Tracer Responsible person for the equipment identification and labelling.
Traceability
Ability to trace the history, application or location of an entity by means of recorded identifications [ISO 8402:1994 standard, “Quality management and quality assurance”].
Traceability system
Set of hardware and software tools together with operational procedures allowing traceability.
To Trace Retrieve data of a traced physical piece of equipment from the traceability database.

Contrôle Radiologique du Matériel
Tout matériel retiré du TUNNEL LHC doitOBLIGATOIREMENT être contrôlé par DGS-RP(contrôles activation + contamination si nécessaire)
Déposer le matériel dans la zone tampon Renseigner les données du matériel dans TREC Informer DGS-RP si réutilisation urgente du matériel
NB: Pour le matériel lourd/encombrant informerDGS-RP avant intervention - Tél: 75252
EDMS 1196590 v.1 16
EDMS 1203350
Contrôle Radiologique du Matériel
Tout matériel retiré des zones de service (UL/UA/US/UJ) est considéré comme non radioactif
Par principe de précaution: contrôle obligatoire du matériel par le propriétaire à l’aide du PCM
Attention: tout matériel mesuré radioactif doit IMMEDIATEMENT être déposé dans la zone tampon et signalé à DGS-RP – Tél:75252
