2• Plan for PSS

3• PSS Status

Radiation Monitors/StatusFAT was on 3-4 Sep 2013

Now we have

-5 movable combined stations (trolleys) ready to be

connected to PSS.-2 portable Neutrons.-Some spare parts. G chamber N chamber Display N portable detectors Bridge Roof Service area

- Calibrations kit: On site.

- 2 Gamma portable detector: expected in days.

Passive:

- Gamma dosimeters/ SESAME. Service area SR tunnel

- Neutron TLD’s from Jordan Atomic Energy Commission (JAEC).- In addition to an external service from Landauer for both Gamma& Neutrons for comparable issues, expected in one month.

Plan for PSS Based on the experience of similar installation, the safety integrity level required is SIL-3 PSS equipment:

1. Two cabinets. (One next to the Booster tunnel door, one in the control room)

2. Safety PLC modules. (distributed in two cabinets)3. Tunnel door switch and lock.4. Emergency stop push buttons. (inside tunnel and on the two cabinets)5. Safety relays for main interlocks.6. Search patrol (search buttons, fence inside tunnel, tunnel evacuation

message)7. Public address system (inside tunnel and service area, expandable for SR

phase)8. IP Camera (operator in control room can monitor the status of the tunnel

door)9. Light indicators. ( Horns and beacons, light panels on tunnel cabinet)10. Independent cable tray.11. Network for safety devices.

PSS Interlocks:

1. Safety relays for interlocks: a- Microtron trigger b- Microtron high voltage power supply c- RF interlock d- Vacuum gate valve e- Extraction kicker power supply (to be used in SR phase)

2. Tunnel door switches: a- Electromagnetic lock b- Magnetic switch

3. Interlock signals from each radiation monitor: a- Low level alarm b- High level alarm c- Fault signal
