TT66 in the passage way

between TCC6/TJ7:

• Could not yet be installed because space

is still needed for evacuation of radioactive

material from TNC and the dismantling of

the T9 target was delayed.

• Installation to be completed during the

next technical stop and accesses during

stable LHC physics beam operation.

Operational RP issues20

Studies completed on:

Prompt dose rate in accessible areas

Residual dose rate in the experimental area

Activation (air & cooling circuits)

Detailed Fluka model of the facility

Several operational scenarios considered

Negligible dose rates in the accessible areas in bldg. 876 and surroundings

Top of the shaft sufficiently shielded even for the worse case scenario of HiRadMat operation


Worst case

scenario

Bldg. 876

T9 to TED modification: our plan21

1. Preparatory works & T9 shielding opening2. Remove target & upstream collimator3. Remove downstream collimator blocks (4)4. Install new shielding5. Install TED (not possible right now: TED not ready) 6. Install new upstream collimator block

T9 target to become a TED dump:



22

January 2011: TBID dismounted Dose rate inside collimator volume

(1mx1mx1.2m) was measured (N. Conan):

Reminder: forbidden area if d> 100mSv/h

The 4 copper blocks:

Each block has a hot corner

Axis of bloc 2&3 is outside range of overhead crane

No remote handling foreseen (in 1993)

T9 to TED modification: a big challenge !

Débit de dose télétector 12.01.11

40cm à l’extérieur des blocs : 20mSv/h

5 cm à l’extérieur des blocs : 60mSv/h

430mSv/h 10-15 cm dans les blocs Cu:

1 Sv/h Max obtenu (distance non estimée)



23

Axis of bloc 2&3 is outside range of overhead crane

Take 1&2 / 3&4 together

Use custom-made lifting beam

No remote handling foreseen

Use existing threaded holes (4 per block)

Handling plates must be installed on copper blocks

Each block has a hot corner

Handling plates + extra shielding to protect personnel when fixing plates

Blocs will be placed inside container in sarcophagus downstream TNC (40cm iron)

T9 to TED modification: a big challenge !



24

Extensive tests on mock-up

(carried out 01&02/02/2011, extensive report on EDMS1119840)

T9 to TED modification: mock-up test



25

Presentation in ALARA L3 committee of 17/01 & 04/02/2011

Extensive documentation (procedure, DIMR, thorough risk analysis, ...) in EDMS for approval

T9 to TED modification: ALARA approval

We managed to squeeze the HiRadMat installation work foreseen initially in two shutdowns in only one year

Despite the disturbance caused by the “Copper block story” and thanks to the efforts and flexibility of many people the HiRadMat is well on track, with commissioning sometime in Summer’11 with first experiments hopefully later in Autumn’11

Within the project, old facilities: T1 & T9 targets, WANF have been dismantled which is a bonus for CERN

Lot of work is being put to fine tune the irradiation area and the associated infrastructure in view of the future users and the future experiments

We are quite pleased to receive 12 beam requests and we hope to be able to do some experiments in 2011. The decision to run the LHC the whole 2012 is welcome and allow us to establish a challenging schedule for 2012 as well

Doing experiments in HiRadMat would be very interesting, lots of physics questions to answer, but also very challenging

Summary

Spares33

Risk analysis34

:Questions to be addressed:

For each possible incident: what are the consequences?

How frequently each possible incident might occur?

Risk evaluation matrix

takes into account:

Probability of occurrence

Severity of consequences

Risk is the “product” of the probability times the severity

M. Gruwe - IEFC Workshop 2010


M. Gruwe - IEFC Workshop 2010

Risk management35

Questions to be addressed:

What can we do to minimize the probability of an incident?

What can we do to minimize the consequences of an incident?

What can we do to minimize the risk?

What do we choose to do, and why ?

Content: Explanation of the technical and organizational choices

Purpose is to ensure

Adequacy of the system with the requirements

Traceability of the technical and organizational choices

Validity in time of these choices

Coherence (in time) between the system and the safety requirements
