Use of 35-60 MeV electrons to make very hard X-rays via Bremsstrahlung radiation

At higher energy unwanted reaction can happen resulting in Zircon-89 and Yttrium-

Conclusions feasibility study

Electron accelerator is feasible production method for Mo-99/Tc-99m

Commercial feasibility• Full cost 30% lower than with

nuclear reactor (NRG modelling)

• Investment of 65 MEuro per

beamline depreciated in 20 year

• Financing by consortium

Technical feasibility• Production volume

of 2 beamlines similar

to HFR: 200.000 6d-Ci/yr

• Existing generators can be

used

• Accelerator using modules of

ASML FEL

• Production of other radio-

isotopes is possible

Durability• Installation intrinsically safe

• Minimal nuclear waste generated

since production with electron

accelerator is very specific

• Modelling shows quality of

Mo-99 meeting requirements

Social importance• Medical need: Supply

guaranteed in consortium with

Generator Manufacturer(s)

• Employment: Potential

continuation of employment

with consortium including build

and operations of facility

Political importance• Investments are 4x lower

for production of radio-

isotopes with electron

accelerator than for

nuclear reactor

• Location of electron

accelerator and production

of radio-isotopes open for

discussion and depending

on consortium members

Next steps• Experimental

verification

• Create consortium

with Generator

Manufacturer(s)

• Start of production

possible by 2020

• Components in isotope accelerator are the same as designed for EUV-FEL

• Laser induced injector generates beam of 30 mA

• Super-conducting linear accelerator accelerates electrons to 60 MeV

• “Kicker” beam splitter and transport optics split the beam such that Molybdenum target is exposed from both sides Developed by

The yield challenge

Three conflicting challenges

have to be addressed

simultaneously in the design

of the exposure cell

The Thermal Challenge• Beam of > 1MW deposited in

Molybdenum

• Molybdenum should not melt

• Maximum cooling 30 W/mm2

• Design drives towards:

• Lower beampower

• More Molybdenum

• Enlarge Mo surface

The Specific Activity Challenge• Loading state-of-art generator with

certain capacity of Mo-99 requires

minimal Specific Activity

• SA should be >130 Ci/gram (End

of Exposure)

• Design drives towards:

• Longer exposure

• Less Molybdenum

The Yield Challenge• Sufficient production of Mo-

99 should be realized to

justify investments

• A beamlines should produce

100.000 Ci/yr (6d EoP)

• Design drives towards:

• Shorter exposure

• Higher beam power

Technical feasibility

Production volume of 2 beamlines similar to HFR

Electron beam

Two beamlines can produce

200.000 6d-Ci/year End of Processing

• Compare to HFR capacity of

170.000 6d-Ci /year End of Processing

Simulation results by NRG and RuG• Central 20 mm of disks :

762.612 Ci/yr End of Exposure @ 130 Ci/gr

Outer part of 30 mm of disks:

170.169 Ci/yr End of Exposure @ 37 Ci/gr

• Two beamlines of 30 mA at 60 MeV

• Ratio of activity between “End of Exposure”

and “6days End of Processing” is <7.5
