EADS Sodern Amendment

Hello Eric,

I am attaching some documents which should clear up the construction

questions that you had. The area completely surrounding the NEM is HDPE (you

can see the blue modular HDPE blocks in the photos). If you look at the top

2 pictures (particularly the one on the upper right) you will see the steel

supports (also blue) around the perimeter of the CNA. Each modular unit to

the right and left of the NEM is about 29" wide. The entire unit is about 1

meter wide.

If you should have any further technical questions you wish to contact

Damien Smith at Dsmith@sodernusa.com.

Please do everything you can to move this forward as quickly as possible. We

have a very tight deadline with our new project in Illinois, and need to

have this amendment submitted to Mr. Henry in Illinois before we can move

forward.

Thanks for your time, we will appreciate anything you can do for us.

Annex 4: CNA Safety devices & controls

Risks Security devices or risk prevention

Radiation Shielding blocks all around the neutron source reduce the dose rate in the

protection when vicinity of the CNA. The shielding blocks are PE shells filled with a

CNA ON neutrons stopping material (mixture of paraffin and PE)

Radiation dose rate are controlled by the manufacturer (SODERN) in the

manufacturing site and by the user on site

Automatic Radiation Protection: fence around the CNA which delimits a

radiation area.

The user can connect a warning light to the tube emission signal to warn

people about the presence of neutron emission.

People attempting A security switch installed by the CNA user on each access door of the

to penetrate into fenced area will automatically switch off the generator. Each security

the fenced area switch is serially linked to the security loop, which directly control the

generator ON/OFF (hardware link with not software dependant).

Radiation posting on the fenced area, installed by the CNA user, warn

about the presence of radiations.

People attempting NEM access is protected by two levels of security devices: • one security

to open the CNA switch on the outside door of the NEM access door, ° one security switch

and access to the on the NEM drawer itself. Each security switch is serially linked to the

NEM security loop, which directly controls the generator ON/OFF (hardware link

with not software dependant).

The security switches used are Class III magnet auto-controlled high

security switch. The good working order of the security switches is

checked on each CNA by the manufacturer (SODERN).

Radiation posting are stick on the different faces of the CNA to warn about

the presence of possible radiation

Radiation dose The dose rate in contact with the CNA when the generator is OFF is lower

when the neutron than 0.5 pSv/h. The surrounding area of CNA when the generator is OFF

generator is OFF can thus be considered as a public zone.

Risk during Maintenance and service operation are to be done when the generator

Maintenance and and the CNA electronics is OFF, as described in the user manual.

service

Electrocution The whole CNA electronics, through its design and its manufacturing,

passes all the CE certification qualification.

All the electronic equipments are integrated and tested in the

manufacturing plant.

All the electronic equipments of the shielding are protected in hermetic

IP55 boxes.

No part under voltage is accessible from outside. Warning posting is stick

on the CNA and on the electronic boxes.

All metal parts are linked to the earth point.

HV cables are protected by very rugged insulating sheath

CEM The compliance to the CE specification with emission of electromagnetic

limits has been qualified in the frame of the CE certification.

The jointed arms: folded and unfolded

Wipe carefully the access gate plate so that the drawer of the NEM will slide on it easily.

EADS SODERN recommends the operator to use the provided suction grip for this step.
