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.”

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 trec.support@cern.ch

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
